Best Solar Panels: Which One Should You Choose? | EnergySage

Choosing the best solar panel can feel overwhelming, but it's easier than you think. A quality solar installer will typically install quality solar panels, so your main focus should be choosing the best solar installer for the job—your installer's experience and your solar system's size have a bigger impact on effectiveness. Still, every home is different, and most will benefit from having the most efficient panels on the market.

JM Product Page

However, timing is critical: The 30% residential solar tax credit is currently set to expire at the end of this year, and equipment shortages are already affecting the availability of top-tier solar panels. While the panels ranked below represent the absolute best performance available, securing the 30% federal tax credit should be your top priority. If your preferred high-ranking panel isn't available or causes project delays, choosing a slightly lower-ranked but readily available panel is often the smarter financial move—the ITC savings will likely outweigh the small performance difference.

Based on our analysis, Maxeon offers the best solar panels, followed by VSUN, REC, Qcells, and Canadian Solar. Each scored well overall, but the best one for you depends on your home’s specific needs.

Maxeon’s 440-watt solar panel is our pick for best overall. It’s the most efficient panel at 22.8% and comes with the longest warranty (40-year performance and product warranties—15 years longer than the industry standard). Maxeon is the highest-rated solar panel on the EnergySage Marketplace. 

The biggest downside to Maxeon solar panels is the price tag. At $2.84 per watt, it’s one of the most expensive brands available. Its specs are stellar, but if budget is your priority, you can likely find a cheaper panel that still meets your efficiency needs.

“My panels were installed in April . I paired them with Enphase IQ8A’s and they put out a TON of power. On a hot summer day, each panel is putting out almost 380 watts per panel, which I’m very happy with. I bought Maxeon panels because they are the most reliable panels with their unique cell design that is different than anyone else’s on the market. And surprisingly, the pricing I got was actually less expensive than some higher-end panels like REC AlphaPure and Panasonic Evervolt. Would highly recommend!” -mattjohnson, EnergySage (edited for grammatical clarity)

What sets VSUN apart is its larger-format panel that maximizes power density. Because its panels are larger, you may need fewer of them for your roof, which may lower the cost of your purchase and installation. It’s an attractive choice for homeowners who have big roofs and want fewer, more powerful panels.

That said, the size of the VSUN panel is also its downfall—they may be too big for some roofs with smaller spaces. Also, the panel’s temperature coefficient is higher than premium competitors—which means they don’t work as well in hotter temps—making these panels a less viable option for homeowners in hot climates.

REC is a longtime favorite among EnergySage shoppers, probably because of its relatively low price per watt and impressive specs. Out of our top brands, REC offers the best bang for your buck: The Alpha Pure 410-watt panel maintains efficiency above 22%, and it has solid 25-year performance and product warranties. These panels also have one of the lowest temperature coefficients on the market, which means they perform better in hotter temperatures compared to other panels.

REC does the best job of balancing top-tier specs and affordability, but it falls short of Maxeon in terms of efficiency. We’re also hearing from installers that REC is experiencing supply shortages, so it may be hard to get your hands on these panels if you’re planning to install your system in time to claim the tax credit.

“Really happy with the great technology from REC. They have the best panel on the market and their 25+year history in the solar industry is really important to me.” -gdavissolar

“Simply put, the Alpha series panel is the best in the market right now. Being a solar consultant for the past 8 years has afforded me the opportunity to learn about panels in a detailed way. The Alpha series matches or beats SunPower in every metric there is, and its costs don't come close to the astronomical price point SunPower demands. I have 38 of these bad boys cranking out power here in Vegas, and I couldn't be happier.” -Tgibs, EnergySage (edited for grammatical clarity)

Qcells is a quality solar panel brand, delivering solid performance comparable to industry leaders. Its 22.5% efficiency exceeds REC, while its robust 25-year performance and product warranty offer peace of mind. Qcells may be especially attractive to homeowners for its sleek all-black aesthetic, competitive pricing, and being made in America—the company has two large facilities in Georgia. 

“I had my system installed in January . Here in Florida, my [panels] make around 100kwh on a full sun day in May through August. I haven't had 1 issue. My highest production day last year was 100 kWh, also, so just glancing at it, I feel degradation first year is less than 2%. It's June now, and the system has already made 10.2 mWh. I'm super happy with the panels. Hope this helps you make a panel decision. I can't rate [REC’s] services as I haven't needed them.” -timhugheseternal, EnergySage (edited for grammatical clarity)

“My system—17.32kWdc—has been running since May 30th, . It's high quality and zero issues thus far. Very happy with my system and the Home Team Energy Installer in my area.” -khanghulam, EnergySage(edited for grammatical clarity)

Canadian Solar’s TOPHiKu6 450-watt solar panel has the highest power output of the products on our list, which means it has the capacity to generate more electricity. While it’s the least efficient of our top brands, it boasts impressive performance specifications with a 22% efficiency rating and  -0.29%/°C temperature coefficient. Plus, despite its name, Canadian Solar manufactures some of its panels in the U.S.

“I had the panels installed on the back of my house 2 years ago. They are doing everything they should do and nothing they shouldn't. Output has been a bit above expectations, and they have been completely reliable. I have 39 panels in place and have not had an issue with any of them. We have had some rough weather, and they have come through it just fine. I would absolutely buy them again.” - mcgrathdw, EnergySage (edited for grammatical clarity)

Jinko didn’t rank first in any category and is the second most expensive panel on this list. It’s a great option compared to most panels on the market, but it lands sixth place when up against the others mentioned here.

The average 11 kW solar panel system costs $20,552 after federal tax credits. That's a lot of money. It's important to choose solar panels that are high quality and affordable. The best way to evaluate if you're getting the best bang for your buck is to divide your solar panel's power per square foot (W/sq ft) by its cost per watt ($/W). The higher this value, the more power per penny you get.

Even the best solar panels may perform poorly in difficult conditions. Some panels are better suited for small spaces, while others excel in hot temperatures. That’s why it’s so important to consider your roof, household electricity use, and climate when choosing solar panels for your home.

An experienced, local solar installer knows how solar performs in your area and can properly inspect your roof to recommend the best panels. But if you want to start some of the research, here are some things to think about:

Have a small roof with a lot of shading? You'll probably want a very powerful solar panel (unless you use very little electricity). Even light shading can reduce your solar panels’ output by 50% or more. Look for solar panels with high power output and high efficiency. 

It's no secret that solar panels are more prevalent in the Sun Belt than in other parts of the country, but they're also an excellent investment if you live in the Northeast or Midwest. You just need to choose the right panels. Your region and climate influence the performance of your panels— things like sun power, shading, panel orientation, temperature, precipitation, wind, dust, and dirt play a role. 

If you live in a place that sees a lot of rain, snow, or other cloudy conditions, you’ll want high-output and high-efficiency panels. If you live in a hot and sunny region, you're in a prime spot for premium solar panel efficiency and will want to pay attention to temperature coefficient as a leading factor in your decision-making.

If your roof is small and you don't have a lot of space for your system, investing in the most efficient, highest-performing panels can get you the performance you need. If you have enough room for a larger system, installing slightly less efficient panels could provide ample output at a competitive price. 

But at the end of the day, going solar now, while you can claim the residential tax credit, will lead to greater savings than waiting for the perfect solar panel. If federal clean energy tax credits are eliminated, the cost of solar and electricity will rise, which means even a few months could mean missing out on thousands of dollars in savings.

While Powered by Elevation is our team’s top-rated solar installer, we also found that Sunrun, Blue Raven, Palmetto Solar, and Venture Solar offer high-quality solar installations and overall value.

• Offers a highly transparent pricing model with itemized quotes
• Uses a comprehensive home approach, including energy audits and additional efficiency improvements

Keep in Mind

• Only operates in five states*
• May have a longer installation timeline due to a thorough assessment process, per customer reviews

Our Review

If you’re looking for more than just solar panels, Powered by Elevation takes a different approach to home energy solutions. Unlike traditional installers such as Sunrun or Blue Raven, which focus primarily on solar installation, Elevation starts with a comprehensive home energy audit to understand your complete energy profile. Its proprietary Curb energy monitoring system provides some of the most detailed energy usage tracking we’ve seen in the industry, helping you understand exactly where your power is going and how to optimize it.

What really sets Elevation apart is its commitment to total home energy efficiency. While most solar companies simply size a system based on your current usage, Elevation’s team identifies efficiency improvements that could reduce your energy needs before installing solar. This might mean suggesting upgrades to your home’s insulation, HVAC system, or other improvements alongside your solar installation. This selection is why it scores higher on our rating scale, but we placed it lower because our other top recommendations feature better service around only solar panel installation.

However, according to customer reviews we analyzed, Elevation’s thorough assessment process could mean longer installation timelines than companies such as Sunrun. While its pricing is transparent, with detailed itemized quotes, this approach comes at a premium. If you’re within their service area and interested in a whole-home energy solution rather than just solar panels, Elevation’s attention to detail makes it a compelling choice.

Elevation has an A+ rating and accreditation from the BBB with a 4.1 out of 5-star customer review rating. While some customers mentioned Elevation’s professional and helpful customer service staff and high-quality solar equipment, others noted ongoing problems with getting assistance from the company for system maintenance.

“For those who are looking to buy solar panels, you should consider Elevation—or at least give them a call and to answer your questions. Everyone has different experiences with solar companies, some good and some bad, but for me Elevation is the best. They were my first and only solar company and I have been with them for well over five years. …. I was very surprised to get a call back the same day. I was even more surprised that I have received several calls over the years just checking to see how my system was working and if everything was fine.” —Bil G. via the BBB in August

“I have had multiple technical issues with the solar system [which was] installed in summer of , requiring technicians to come to my home to perform repairs every few months. Given the young age of the system, it is frustrating to deal with this many quality issues. The parts are under warranty, but I have just been informed that Elevation has a ‘policy change’ and now each visit which was originally offered free of charge is now subject to a $200 fee for labor.” —Amber A. via the BBB in October

Average Cost: $14,812

NABCEP Certified: Yes

Warranty Length: 25-year equipment, 10-year workmanship, 10-year roof penetration

Performance Guarantee: 90% of estimated energy production

Company Overview

• Includes high-quality battery storage solutions such as the Tesla Powerwall and its own unique Brightbox system
• Partners with major retailers such as Costco to offer member discounts
• Provides comprehensive system monitoring through its user-friendly mySunrun app

Keep in Mind

• Has mixed customer reviews, with some complaints about aggressive sales tactics
• Some lease contracts and power purchase agreements (PPAs) have long terms of 20–25 years

Our Review

Sunrun is one of the biggest names in the U.S. solar industry. With over 15 years of experience and operations in more than 20 states, Sunrun has established itself as a major player in residential solar.* Its partnerships with retailers such as Costco can offer attractive member discounts, and its comprehensive monitoring system through the mySunrun app helps you track your system’s performance. Plus, it provides solid battery storage options, including Tesla Powerwall and its own Brightbox system.

Brightbox is Sunrun’s branded version of the LG Chem battery system. It provides backup power during outages and maximizes solar energy usage. The system stores excess solar power generated during the day, allowing you to use that energy at night or during power outages. Depending on your energy usage, the system typically provides 20–30 hours of backup power to essential home appliances.

However, our research reveals that bigger isn’t always better in solar. While Sunrun’s size gives it significant resources, the company typically charges more than smaller local installers for similar installations. Unlike companies such as Blue Raven Solar, which consistently receives high marks for customer service, Sunrun’s performance varies significantly by location. This is partly because it often uses third-party contractors rather than in-house installation teams. Despite these issues, Sunrun is a stable, established choice with strong warranties and reliable technology.

Sunrun holds an A+ rating and is accredited by the BBB, with an average customer rating of 3.2 out of 5 stars. Many customers have shared positive experiences regarding their initial installation and activation, noting that their solar system is producing energy efficiently. However, the majority of negative feedback is related to challenges with ongoing support and communication difficulties. In some cases, customers have also reported payment issues such as double charges, which can take several weeks to resolve.

“I just completed my second year as a Sunrun customer and I have been very pleased with my solar panels and solar production. [My] Sunrun consultant has been very helpful, especially in how to understand my ComEd bills and how my solar panels save me money. He is very through in his explanations and patient with me. I highly recommend Sunrun for the quality of service and excellent products.” —Kathleen R. via the BBB in January

“Sunrun double charged my account and will not give me a timely refund. I’m asking them to resolve this now but they are insisting it will take 3–4 weeks. I should not have to wait on a mistake to rectify at my expense when a company wrongfully charged my account. I’m really upset with their service and have to constantly monitor my account now.” —Rose W. via the BBB in April

Company Overview

• Offers an innovative BluePower Plus+ financing program with 18 months of free solar
• Uses in-house installation teams rather than contractors
• Customer reviews describe quality customer service with dedicated project coordinators

Keep in Mind

• Doesn’t offer leases or PPAs
• Has a more limited service area than some other companies*

Our Review

If you’re looking for top-tier customer service and transparent pricing, Blue Raven Solar stands out. What impressed us most during our research was the company’s consistent track record of clear communication and dedicated project management. These things are something that larger providers such as Sunrun often struggle with. Blue Raven uses in-house installation teams rather than contracted workers, which helps it deliver consistent quality.

Blue Raven’s financing approach is where it really shines. Its BluePower Plus+ loan program offers 18 months of free solar, making the transition to solar power more accessible for many homeowners. While it doesn’t offer leases or PPAs like Sunrun, Blue Raven’s financing options can work out better financially in the long run. Unlike leases, you own your system and can claim incentives with loan financing.

However, Blue Raven operates in only 17 states, primarily in the Midwest and Southeast, so it’s not an option for everyone. It also has a more limited selection of equipment compared to some providers, as it primarily works with Trina and Canadian Solar panels. And if you’re specifically looking for advanced battery storage solutions, you might want to consider other companies with more extensive battery offerings. That said, if you’re within its service area and looking for a straightforward solar installation with quality customer support, we recommend getting a quote from Blue Raven.

Customer Experiences

Blue Raven Solar has earned an A+ rating and accreditation from the BBB. The company currently holds a customer rating of 4.1 out of 5 stars. Many customers commended Blue Raven for its professionalism and the quality of its installation services. However, some customers reported confusion about promotional offers, unwanted spam calls, and instances where systems did not meet promised energy goals.

“After considering going solar for a long time but not being able to connect with the ideal company, I finally partnered with Blue Raven in . From the customer service team to the installation crew, the entire process was very transparent and informative, giving me the confidence that I was working with a reliable and experienced team in the solar industry. Working with Blue Raven surpassed all my expectations, and I wholeheartedly recommend it to anyone who values quality, reliability, and peace of mind.” —Marcelo C. via the BBB in February

“Poor communication and have holes in the wall and ceiling. Been dealing with [their] corporate [staff] for four months and can not get anyone out to help. I would not recommend Blue Raven. We were told two months up and running from install! Now going on four months and still not running!” —Angela S. via the BBB in April

Palmetto Solar

4.4 Overall Score Cost $21,812 Warranty 25-year panels, 10-year workmanship BBB Rating A+

Average Cost: $21,812

NABCEP Certified: Yes

Warranty Length: 25-year equipment, 10-year workmanship

Performance Guarantee: 95% of estimated energy production

Company Overview

• Customers report satisfactory service and a quick installation processes
• Offers comprehensive monitoring and maintenance service through its Palmetto Protect plans
• Provides virtual consultations and online quotes

Keep in Mind

• Uses third-party contractors in some locations rather than in-house teams
• May charge higher prices for solar installation than competitors

Our Review

If you’re tech-savvy, Palmetto Solar offers something unique. The company’s standout feature is the Palmetto Protect plan, which provides some of the most comprehensive solar monitoring and maintenance in the industry. Unlike basic monitoring systems from companies such as Sunrun or Blue Raven, Palmetto provides detailed performance tracking, proactive maintenance alerts, and easy access to customer support through its user-friendly mobile app.

Operating in 19 states, Palmetto offers high-quality equipment and long-term customer support. Its equipment selection includes top-tier manufacturers, and its 25-year panel warranty matches industry standards. However, the company may charge higher prices compared to some competitors. Palmetto’s installations typically come at a premium, especially when you factor in the additional cost of its Palmetto Protect service.

The main trade-offs with Palmetto include its installation model and pricing structure. Unlike Blue Raven Solar, which uses in-house teams, Palmetto often works with third-party contractors, leading to some inconsistency in installation quality and timing across locations. While Palmetto’s technology platform is impressive, you’ll need to weigh whether the higher costs justify the additional features.

Palmetto Solar holds an A+ rating from the BBB, but is not accredited. The company has a customer review score of 3.2 out of 5 stars. Positive feedback highlights the responsiveness and assistance provided by Palmetto employees, including customer service agents and installers. On the other hand, some negative reviews point out challenges related to ongoing support and difficulty in reaching customer service after the initial installation.

“Working with Palmetto staff has been easy from our first conversations to switching on our panels. The[y] provided answers to our questions—researching answers they weren’t 100% on. Husband was very skeptical about solar, but the [rep] did her best to address each issue. She managed to leave him without further concerns! Rather than financing, we received a significant discount for paying cash…. Install was easy and without issues. We became operational a few weeks after installation was complete. We’ve been operational almost six months and are happy with performance and monthly electric bill savings.” —Cheryl L. via the BBB in November

“[Palmetto] is nonresponsive and they are almost impossible to get on the . It seems they like to . We were notified [on] Sept. 25, that our solar [system] was not working. It was finally resolved on Dec. 2, at a cost of $360 to replace a fuse. Wouldn’t recommend Palmetto because trust is broken and those costs are ridiculous.” —Carol C. via the BBB in January

Best Northeast Regional Installer

Venture Solar

4.8 Overall Score Cost $13,636 Warranty 25 years BBB Rating A+

Average Cost: $13,636

NABCEP Certified: Yes

Warranty Length: 25-year manufacturer and labor warranty

Performance Guarantee: Varies by solar panel manufacturer

Company Overview

• Uses in-house installation teams for more consistent quality
• Has a strong presence in the Northeast with local expertise
• Creates custom system designs based on a detailed roof analysis

Keep in Mind

• Has limited battery storage options compared to larger providers
• Only operates in Connecticut, Massachusetts, and New York

Our Review

If you’re looking for top-tier installation quality in the Northeast, Venture Solar has built an impressive reputation. Venture keeps everything in-house with its own installation teams, which shows in its attention to detail. Venture is particularly skilled at handling the unique challenges of Northeast homes, such as working around snow and ice and historic properties with complex roof designs. Venture’s workmanship warranty is one of the longest we’ve seen, covering your installation for 30 years compared to the typical 10-year coverage from most competitors.

While some companies such as Blue Raven focus on rapid installations, Venture takes extra time to analyze your roof structure and shading patterns in detail. This can mean longer wait times during peak seasons, but the resulting systems can offer more efficiency and better integration with your home’s architecture. Also, Venture’s project managers provide consistent communication throughout the process, which is a change from the sometimes spotty communication you might experience with larger national providers.

However, Venture is currently limited to New York, Massachusetts, and surrounding areas, and the company doesn’t offer lease or PPA options as with some larger providers. If you’re in Venture Solar’s service area and value quality over cost, the company’s combination of technical expertise and attention to detail makes it a standout choice.

Customer Experiences

Venture Solar holds BBB accreditation with an A+ rating and boasts a customer rating of 4.7 out of 5 stars. Customers often praise the professionalism and efficiency of the company’s scheduling and installation teams. However, some negative reviews express dissatisfaction with the length of time required for inspections and activation.

“Last Thursday I had the pleasure of having 36 solar panels installed on my home by Venture Solar. I am thrilled to share that my experience was nothing short of exceptional! The entire process took just one day, and the team worked efficiently and professionally. The installers exhibited a high level of expertise, ensuring everything was done to the best standards. From the initial consultation to the final walkthrough, the customer service was outstanding, with clear communication every step of the way. Whether it was the sales team, project manager, or support staff, everyone went above and beyond to provide a seamless experience.” —Timothy F. via the BBB in January

“After initial installation of [my] solar system, they started to charge my account, though it never produced a watt of electricity for me. On top of that, my electricity bill went up 100% percent. I informed the company that there is an issue and they admitted it, but nothing happened since then. They [are] charging my account monthly, [but] I am not receiving any power, instead I am having 100% higher bills.” —Dimitry P. via the BBB in August

Solar Insights, Regulations, and Incentives

The solar industry is experiencing remarkable growth, with residential solar installations increasing by 40% year over year as of late . Rising electricity costs, improved solar technology efficiency, and federal incentives largely drive this surge. The federal solar tax credit remains at 30% through . The federal solar tax credit enables you to claim 30% of the total cost of your solar panel system as a credit against your federal taxes. For example, if the installation of your solar panel system costs $10,000, you will receive a tax credit of $3,000.

“Solar PV installation is best viewed as an investment, with payback period being the crucial metric—system cost divided by annual savings indicates how many years until the initial investment is recouped,” says Farzan Kazemifar, Ph.D., P.E., associate professor and associate chair at San José State University Department of Mechanical Engineering. “Recent market trends show decreasing component costs alongside rising electricity rates, generally improving the value proposition.”

At the state level, regulations and incentives vary dramatically. Some states, such as California, have mandated solar panels for new residential construction, while others offer additional tax incentives, rebates, or performance payments. Net metering policies, which allow you to sell excess power back to the grid for billing credits, remain a hot topic, with some states scaling these programs back and others strengthening them. For example, California’s updated NEM 3.0 policy has reduced the value of excess solar energy sold back to the grid, while states such as New York and Massachusetts maintain more generous compensation rates.

The Inflation Reduction Act of has also transformed the solar landscape by extending and expanding various clean energy incentives. In addition to the 30% federal tax credit, the act provides additional incentives for American-made equipment and battery storage systems. Utility companies are increasingly implementing time-of-use rates and demand charges, making battery storage more attractive for homeowners looking to maximize their solar investment by using stored energy during times of increased grid rates.

How To Choose the Best Solar Company

When choosing a solar installer, evaluate the company’s credentials and specific offerings for your home. The best solar companies typically have at least five years of experience, strong manufacturer partnerships, and proper certifications, including North American Board of Certified Energy Practitioners (NABCEP) certification for installers. Insurance coverage is important, too—look for companies that carry both general liability insurance and workers’ compensation insurance to protect you and your property during installation.

“Homeowners should evaluate a solar company’s reputation, customer reviews, warranties, financing options, and certifications (such as NABCEP),” says Abbas Ghassemi, Ph.D. “They should obtain multiple quotes to compare pricing and equipment quality, check for hidden fees, and ensure the company customizes the system to their home’s energy needs, and if they offer financing options, ensure they provide clear, transparent contracts. They should verify the warranty offered, including coverage for panels, inverters, and labor. Local companies often have a better understanding of regional regulations and climate conditions, which can be beneficial.”

Here is a list of key factors to consider when comparing solar companies:

• Certifications and insurance: Check that the company has NABCEP certification for its installers and any state-specific licensing. Ask about its general liability insurance, which should include a minimum of $1,000,000 in coverage, as well as workers compensation insurance.
• Customer support: Gauge the company’s responsiveness during the sales process by asking about any project timeline commitments. Check the company’s post-installation support and customer reviews and ratings on platforms such as the BBB and Google Reviews. You can also check for any complaint resolution history on these sites.
• Experience: Check to see how many years the installer has been in business and whether it has an installation track record. Ask about its financial stability and manufacturer partnerships. Also, check to see if it uses in-house installation teams or subcontractors. Subcontractors are a common occurrence in the solar industry, but we recommend you seek companies with in-house teams for more consistent quality and easier communication. However, subcontractors do not automatically mean you’ll receive less quality service.
• Financial options: The more financing options a company offers, including cash purchases, solar loans, solar leases, and PPAs, the better. Ask about any interest rates, terms, and down payment requirements for a loan or lease.
• Products and services: Check into the reputable brands of panels and inverters offered by the installer. The same goes for the installer’s battery storage options and system monitoring capabilities. A company offering additional services, such as roof repair and other energy efficiency upgrades, is a good sign, as it can help you streamline your entire home energy upgrade process.
• Warranties: A reputable solar installer should offer a 25-year equipment warranty and a 10-year workmanship warranty. High-quality companies may also include a power production guarantee for your system output and a roof protection warranty.

Solar Warranties and Performance Guarantees

Unlike home systems and appliances, which typically only have one warranty, solar panel systems have three different types of coverage. Learn more about different solar warranties: 

• Product or equipment warranty: This warranty covers your solar panels against factory defects and replaces any malfunctioning components. Depending on the solar brand and product line, this warranty can range from 10–40 years. We recommend purchasing solar panels with at least a 25-year product warranty since the typical panel lifespan is around 25–30 years.
• Workmanship warranty: While a product warranty replaces defective solar panels, a workmanship warranty covers the cost of installation and labor if you need a replacement. Reputable solar companies typically provide a workmanship warranty of at least 10 years, and in some cases you may receive coverage for 25 years or more.
• Performance or power production warranty: Solar panels gradually lose performance over time. This type of warranty specifies a maximum panel degradation rate, typically below 0.5% annually, and replaces any panels that degrade faster.

Solar system warranties protect both your investment and your long-term energy savings. However, getting a professional solar installation is critical if you want warranty coverage. Solar manufacturers will typically void your warranty if the system was installed incorrectly.

How Much Does Installing Solar Cost?

Solar panel costs have become increasingly competitive in recent years, offering a more attractive investment for homeowners looking to reduce their energy bills and carbon footprint. As of , solar costs about $14 per panel. Most home solar energy systems cost around $16,129, according to our survey of 1,000 residential solar customers. However, the total cost of a solar installation depends on various factors, including system size, panel type, location, and local labor costs.

“Try to find photovoltaic panels of high efficiency, even if they cost a little more,” says Carrick Eggleston, Ph.D. “The very best commercially available panels now have efficiencies of over 20%. I also recommend systems that have what is called ‘maximum power point’ control units on each panel.”

When considering solar panel installation, it’s important to understand that the price isn’t just about the panels themselves. The total cost includes hardware such as racking, wiring, and inverters, as well as labor for installation. Your roof’s size, angle, and complexity can also impact the overall cost, as can local permitting fees and regulations. Additionally, the choice of solar panel brand, efficiency, and output rating can affect the price, with higher efficiency panels generally costing more but potentially requiring fewer panels overall.

To give you a clearer picture of what you might expect to pay, here’s a breakdown of typical solar costs across systems sized for residential use.

Survey Insights from Solar Customers

In , we surveyed 1,000 homeowners across the U.S. who have recently purchased and installed solar panel systems. Our goal was to understand their experiences, costs, and the factors that influenced their choice of a solar provider.

The majority of homeowners spent approximately $16,129 on their solar panel system, with an average of 14 panels installed per home. This investment translated into notable energy savings, with most homeowners reporting a monthly reduction of $196 on their power bills—equivalent to about $14 per panel in savings.

When it came to choosing a solar installer, our survey revealed that Sunrun was the most popular provider among respondents. However, a number of respondents selected local or regional solar companies instead of a national installer. We recommend considering both options when comparing solar providers in your area to find the best deal.

Fifty-three percent of homeowners cited reducing electricity bills as their main reason for installing solar panels. These findings highlight the financial benefits of solar energy while also emphasizing the importance of researching and selecting a solar company that aligns with both your budget and service expectations.

FAQs About the Best Solar Companies

How long does it take to install a solar system?

The installation process typically takes 1–3 days. However, permitting, inspection, and utility approvals can extend the timeline to 1–3 months.

Do solar companies maintain the system after installation?

Many companies offer maintenance packages or warranties that cover repairs and upkeep after installation. However, solar systems typically require minimal maintenance, such as occasional cleaning and visual inspections. This differs if you purchase your system with a lease or PPA, however, in which case the installer maintains ownership and system upkeep as a result.

How do I know if my home is suitable for solar panels?

The suitability of solar panels on your roof depends on several key factors. South-facing roofs maximize sunlight, while east or west-facing roofs can still work but produce slightly less energy. Roof slopes between 15 and 40 degrees are ideal for performance. Make sure your roof is in good shape, with any necessary repairs completed before installation. Investigate local climate conditions using tools such as Google’s Project Sunroof or the Global Solar Atlas for insights.

What happens to solar panels during cloudy days or at night?

Solar panels still produce electricity during cloudy days but at a reduced rate. Depending on the thickness of the cloud cover, panels may generate 10%–50% of their typical output. Solar panels do not generate electricity at night because they require sunlight to activate the photovoltaic cells. Installing solar batteries lets you store excess energy generated during the day for use at night or on cloudy days.

How We Evaluated Solar Companies

We ranked the top solar installation companies based on equipment and service options, warranties and performance guarantees, certifications, and experience. We made sure every company offers at least high-quality monocrystalline solar panel installation and backup battery storage options.

Our Rating System

To determine the best of the best in residential solar energy, we’ve created a rigorous methodology that helps us analyze providers. We assessed each company in six key areas, from service options to the fine print of warranty coverage.

• Solar equipment and services: We read through each provider’s service catalog to learn what residential solar services they offer, including helpful additional services such as a dedicated app or web portal, energy audits, monitoring services, and roofing services. These services both help speed up and maintain solar panel installation. We also checked into whether or not a provider uses in-house installation crews or outsources to a third-party company.
• Warranty and performance guarantees: We went through each company’s warranty coverage and guarantees to make sure you receive adequate coverage and protection for factory malfunctions or improper installation issues. Companies that offer 25 years or more on workmanship and performance received the most points, with additional points offered for including a production guarantee or roof leak coverage.
• Brand reputation and professional certifications: We checked each provider on the Better Business Bureau (BBB) and analyzed hundreds of its most recent customer reviews to get realistic insight into what it’s like to work with that company. Additionally, we checked for ongoing lawsuits or alerts, and that the company holds NABCEP certification.
• Financing options: We reviewed each company’s payment and financing options. The more payment methods offered, the more points a company received in our review. However, offering leases and PPAs resulted in fewer points, which we find less desirable for long-term cost-effectiveness. We also gave additional points if the company provides in-house financing rather than relying on a third-party lender.
• Industry experience: The longer a company has been in the residential solar industry, the more points it earned in our review.
• State availability: We checked each provider’s service area. The more states a company offers solar panel and battery installation, the more points it received in our review.
