Our top pick for best solar company is Palmetto Solar due to its high-efficiency solar panels, all-inclusive warranty, and positive customer reviews.

Switching to solar power can substantially reduce your electricity bills and power grid dependency. But it is a big investment, so you want to choose a company that will provide you with the best products and services, both now and through the years. 

We’ve researched and reviewed 68 leading solar panel companies nationwide, interviewed industry experts, surveyed 2,000 solar customers, and spent more than 770 hours analyzing product specifications and warranties to find the best in the business. We selected Freedom Solar, Blue Raven Solar, and Palmetto as our top three choices for solar installation companies, with Freedom Solar getting our top vote. See how we compared these companies and other top-rated providers in our review.

Key Takeaways

  • Carefully review a solar company’s efficiency rating, warranty coverage, customer reviews, financing options, state availability, and equipment selection before making your choice.
  • You can greatly reduce your solar panel cost by taking advantage of solar incentives, tax credits, net metering programs, and local rebates.
  • Most homeowners pay for their system in full, but you can reap solar energy benefits sooner by financing your system using a solar loan, solar lease, or power purchase agreement (PPA).

You should know about the best payment options to maximize your investment and which solar incentives you’re eligible for to avoid scammers or untrustworthy companies when going solar.

How much does a solar panel system cost?

The national average solar energy system costs between $17,430 and $23,870.

The cost of your solar panel system varies based on several factors, including the system size, whether it’s installed on or around your home, the installation complexity, and your selected solar panel type. Changes in a company’s technology will also affect the price, as will your region.

We recommend getting quotes from at least three companies to closely compare your options.

What are solar incentives?

Solar incentives, such as tax credits and rebates, help you maximize your return on investment by putting money back in your pocket. For example, the federal government provides a 30% federal solar tax credit that allows you to reduce your federal taxes by up to 30% of what you paid for your solar panel installation. Some solar companies assist you with finding and applying for solar incentives you’re eligible for.

We also suggest you visit the Database of State Incentives for Renewables and Efficiency (DSIRE) to view your area’s state and local incentives.

We recently surveyed 1,000 solar customers about their experiences applying for solar incentives. Nearly 75% said they had taken advantage of solar incentives, 64% said they used the federal tax credit, 32% said they used a net metering program, and 30% said they got a local rebate.

What solar energy terms should I know?

There are a lot of solar energy terms you should know, such as active monitoring and inverter. Here’s a quick breakdown of key terms and their meanings.

  • Active monitoring: Active monitoring means tracking and analyzing various performance metrics for your solar energy system, such as electricity production, system health, and environmental conditions. This continuous monitoring helps you to detect issues promptly, optimize system efficiency, and get proactive maintenance to ensure reliable and optimal operation.
  • Inverter: This is a component that converts the direct current (DC) power your solar system gets from the sun into the alternating current (AC) power that runs your home. 
  • Solar panel efficiency rating: This indicates the percentage of sunlight that solar panels convert to usable electricity. The higher the efficiency rating, the better the energy production. Note that 100% efficiency isn’t scientifically possible. Most solar panels have efficiency ratings between 15% and 22%.
  • Solar battery backup: A solar battery backup system stores excess energy generated by solar panels, enabling you to use that stored energy when the sun isn’t shining, such as at night or during power outages. This product allows for greater energy independence and resilience against grid failures. According to our survey data, most homeowners purchase two batteries to go with their system.

How do I pay for solar panels?

There are several options for solar financing that can fit most budgets. Many companies offer two or more payment choices. A full purchase or loan is typically the most cost-effective option. “When you lease solar panels, you miss out on the substantial federal tax credit because it instead goes to the leasing company,” explains Matt Johnson, co-owner of Namaste Solar. “If you own your own solar panels, you will be the one to reap the financial benefits of the tax credit.”

Johnson adds that leasing your panels could also make selling your home cumbersome and expensive because you have to ensure the new owner wants to take over the lease or buy out the rest of your contract—potentially costing thousands of dollars.

Here is a list of the most common payment options:

  • Full purchase: A full cash purchase gives you full system ownership, qualifying you for all tax incentives and rebates. 
  • Solar loan: This option requires smaller monthly payments for a set time frame and grants you full ownership.
  • Solar lease: Homeowners lease the system from the solar provider and make monthly payments for its use. Check out our guide to solar leasing to determine if this option is worth it.
  • Power purchase agreement (PPA): The solar company retains system ownership and only charges you for the solar energy you use each month.

According to our recent survey of solar customers, 49% chose to pay in full upfront, 23% got a loan, 11% leased, and 17% financed through a PPA.

What warranties come with solar panels?

Warranties can differ based on each company’s products. You could have multiple warranties for one system if the company works with several manufacturers. Alternatively, a solar provider could offer all-inclusive warranty coverage for its in-house products, making the claims process much easier. 

The top companies offer 25-year warranties in most cases, but some limit their workmanship warranty to 10 years. We recommend finding a company that provides 25-year warranties for coverage throughout your system’s lifetime.

Here are the three most common warranties and what they cover:

  • Manufacturer’s warranty (or product warranty): Protects the individual solar system components in case of defects.
  • Workmanship warranty: Covers installation in case of poor workmanship or faulty installation materials.
  • Performance (or power production) guarantee: Certifies the solar system’s output as outlined in your contract.

What Should You Look for in a Solar Company?

First, ensure the installer you’re interested in provides high-quality, monocrystalline solar panels to maximize your solar investment. Also, check that it offers at least a 25-year product warranty and holds the proper certifications to operate in your area.
Here are the key qualities to look out for as you search for a solar company:
Certification: Solar installers may have certifications from specific solar panel and inverter manufacturers. Verify these certifications by checking the official websites of the respective manufacturers. You should also check that the installer is certified by the NABCEP.
Cost and financing: Every solar company in our review offers full purchase and loan financing options. Some also provide leases and PPAs. A full purchase or loan qualifies you for the federal solar tax credit and other cost-saving incentives. A lease or PPA reduces how much you pay up-front, but the solar company still owns the panels, so you can’t qualify for incentives. We recommend you pursue only full purchases and solar loans because of this limitation.
Installation process and services: Some companies offer a completely streamlined installation process, including in-house design, installation, and whole-home energy audits. Other companies use third-party installers, which can make communication and warranty issues more complicated. You should prioritize companies with in-house installers before considering providers that use third-party contractors.
Solar panel quality: Customers can usually choose between monocrystalline and polycrystalline solar panels. Monocrystalline panels are more efficient, so you should consider companies that specialize in these panels.
Warranty options: Each company on our list offers 25-year manufacturer warranties, but some companies’ workmanship warranties are only 10 years. The coverage specifics vary by the installer. A good general rule is to seek out companies offering baseline 25-year product warranties.

Our Top Solar Company Picks

Sunrun

4.5

We like Sunrun for its four financing options, including its unique leasing options if you don’t want to own your system. This stands out to us because the other companies on this list don’t offer as many options.

Prepaid and leased systems also include a 25-year warranty with system service and maintenance, ongoing monitoring, and theft insurance. The company even offers financing plans for quality monocrystalline solar panels and products from trusted brands such as LG.

How We Scored Sunrun

Sunrun earned 4.4 out of 5 stars based on our methodology. The company gained many points for its positive reputation, comprehensive leasing options, and well-rounded warranty coverage. It lost some points for is limited service selection.

  • Solar Equipment and Services (15 out of 25 points): Sunrun provides solar panel and battery installation but uses third-party installers. Though this is becoming an industry standard, in-house installers typically yield better communication and quality. The company also doesn’t provide roofing services or energy audits but does offer quality active monitoring assistance. 
  • Warranty and Performance Guarantees (19 out of 25 points): Sunrun offers quality warranties, such as its 25-year manufacturer and labor warranty, but doesn’t include a performance guarantee. 
  • Brand Reputation and Professional Certifications (13 out of 15 points): Sunrun has one of the higher customer BBB ratings we’ve encountered, and the company maintains an overall positive customer reputation online.
  • Financing Options (13.5 out of 15 points): The company doesn’t offer any in-house financing but provides more warranty coverage for customers interested in solar leasing than other providers, such as Palmetto.
  • Industry Experience (9 out of 10 points): Sunrun holds 17 years of experience in the solar industry, making it a veteran compared to a newer company such as Blue Raven Solar.
  • State Availability (8 out of 10 points): The company only serves 18 states.

Its accolades include Best CEOs for Diversity 2022, Best Company Culture 2021, and Best Company for Women two years in a row.

Sunrun currently holds an A+ rating from the BBB and is accredited. Former customers praised the comprehensive coverage for leased systems but complained about delayed installations, poor customer service, and poor communication with project managers. Additionally, some customers note being confused by Sunrun’s leasing and PPA options, though they also mention Sunrun is willing to discuss and clarify these plans.

Palmetto

4.4

Palmetto Solar offers a wide range of quality solar products and excellent customer service, including phone, email, and online chat options, an online service request portal, and a library of troubleshooting resources. Overall, Palmetto offers more customer support than other providers we reviewed, most notably through its tiered system protection plans and mobile app.

How We Scored Palmetto Solar

Palmetto earned 4.4 out of 5 stars according to our methodology. The company scored more points for its comprehensive service selection and long-term protection plans. It lost some because of its standard warranty options and lack of production guarantee.

  • Warranty and Performance Guarantees (16 out of 25 points): The company’s warranty options don’t stand out as much as Sunrun’s. It offers industry-standard coverage for 25 years on products and 10 years on labor.

Palmetto Solar is accredited by the BBB and has an A+ rating from the site. While reading online reviews, we noticed that homeowners praised Palmetto for its dedicated installation managers and quality systems but mentioned very long waiting periods for permitting, plus installation delays.

Solar Energy World

4.4

Solar Energy World (SEW) is one of the most robust and well-regarded solar installation companies. It boasts several impressive features, such as its 30-year manufacturer’s warranty. Its service area is limited, and it doesn’t offer energy auditing services. We like that SEW discloses what solar panels it primarily works with and that the panels are from trusted, quality brands such as Qcells and Silfab.

Roughly 11% of our surveyed solar users purchased their system from Solar Energy World.

How We Scored Solar Energy World

SEW scored 4.4 out of 5 stars according to our methodology. The company received many points because of its warranty, which is longer than most other solar companies’ warranties. SEW offers a 30-year manufacturer’s warranty on all its solar panels and inverters, whereas many providers only offer 25-year warranties.

  • Solar Equipment and Services (18 out of 25 points): The company is an ideal option for many basic solar products and services, such as solar panels and battery installation. It lost points because it doesn’t install EV chargers or perform energy audits.
  • Warranty and Performance Guarantees (19 out of 25 points): SEW’s manufacturer and labor warranties are standout features, but the company doesn’t include any production guarantees with its work. 
  • Brand Reputation and Professional Certifications (15 out of 15 points): The company’s reputation is one of the best, with high BBB and Google Reviews ratings. We also found no active alerts or lawsuits.
  • Financing Options (13.5 out of 15 points): SEW offers all possible solar payment options but doesn’t provide an in-house financing department. 
  • Industry Experience (8 out of 10 points): The company has been in business since 2009, so it received most of the points in this category.
  • State Availability (6 out of 10 points): SEW limits its service area to eight East Coast states.

Pros and Cons

Pros Features an extensive solar product catalog with trusted brands Includes free active monitoring Hires NABCEP-certified installers and designers Cons Reviews mention communication issues with staff Warranty coverage varies by solar panel brand Doesn’t offer a power production guarantee

Warranty and Financing

Warranty

SEW offers a 30-year manufacturer’s warranty on all purchased solar panels and inverters. However, coverage varies by brand, and the company doesn’t guarantee them with every panel option. 

Financing Options

✔ Full purchase
✔ Loan
✔ Lease
✔ PPA

State Availability

Available in: Washington, D.C, Delaware, Florida, Maryland, New Jersey, North Carolina, Pennsylvania, South Carolina, and Virginia

Reputation and Reviews

The company landed on Solar Power World’s 2023 Top Solar Contractors List in the No. 10 spot.

The BBB accredits SEW, and the company holds an A+ rating. Former customers praise the company for its professionalism, assistance with applying for financial incentives, and smooth installation process. However, some reported discrepancies in finances and scheduling.

Blue Raven Solar

It has won awards for its team and CEO, and customer reviews report great customer service and prompt installations. The company also stands out for its in-house financing, which includes 18 months of free solar energy.

Out of all solar brands in the market, 6.5% of our survey respondents chose Blue Raven.

How We Scored Blue Raven Solar

Blue Raven received 4.4 out of 5 stars according to our rating system. The company scored the most points for its customer service reputation and warranty coverage. It also earned points for providing all standard solar panel services but lost some due to its limited financing options and lack of roof leak coverage.

  • Solar Equipment and Services (18 out of 25 points): Blue Raven offers solar panel and battery installation, active monitoring services, and energy audits. However, it doesn’t offer solar roofs, EV chargers, or additional roofing services. 
  • Warranty and Performance Guarantees (22 out of 25 points): The company offers top-of-the-line warranties, including a 25-year workmanship warranty. The company earned points fo providing a performance guarantee, but its guarantee is shorter than many other providers. However, it doesn’t provide any roof leak coverage. 
  • Brand Reputation and Professional Certifications (13 out of 15 points): Blue Raven has high customer review ratings on its BBB profile and other popular review sites. The company uses in-house installers but doesn’t ensure they’re NABCEP-certified, which made it lose some points in this category.
  • Financing Options (12 out of 15 points): Blue Raven offers some of the best in-house financing of the companies this list, but it limits this financing to solar loans. You may want to consider a different provider, such as Sunrun, if you’re looking for a lease or PPA.
  • Industry Experience (7 out of 10 points): Blue Raven has less experience than other providers, with only 10 years in the industry.
  • State Availability (7 out of 10 points): The company limits its service area to 19 states.

Blue Raven is accredited by the BBB and currently holds an A+ rating. We noted that customers praised the knowledgeable staff and prompt installation but cited poor communication after completing projects. We analyzed several consumer reviews and found that some of these issues stem from the company’s financing department and third-party installers.

Read our review of Blue Raven Solar for more information.

Freedom Solar Power

4.4

Freedom Solar Polar is a SunPower Master Dealer that provides high-efficiency solar systems. The company has 17 years of solar industry experience and partnerships with certified installers. It’s one of the few solar companies to offer grid-tied, ground-mount, carport, and off-grid solar solutions.

Nearly 7% of our survey respondents chose Freedom Solar Power for their installation.

How We Scored Freedom Solar Power

Freedom Solar scored 4.4 out of 5 stars according to our methodology. The company earned most of its points because of its comprehensive warranty coverage and reputable customer service. Its biggest drawback is its basic service selection.

  • Solar Equipment and Services (16 out of 25 points): Freedom Solar has minimal service options compared to companies such as Elevation or ADT Solar. It offers solar panel and battery installation with active monitoring, but that’s it. We do like that it provides in-house installers to do the work.

This design provides a simple, stylish look tailored to your roof’s appearance. Additionally, Venture offers comprehensive financing options similar to Sunrun, making solar energy more accessible to homeowners.

How We Scored Venture Solar

Venture earned 4.2 out of 5 stars. It gained most of its points due to its flexible financing options paired with an in-house financing department. It also provides plenty of solar services to match most customers’ wants and needs, though it lost points for lacking roofing services, energy audits, and EV charger installations. 

  • Solar Equipment and Services (16 out of 25 points): Venture offers solar panel and battery installation with active monitoring. The company lost points in this category because it doesn’t provide EV chargers, solar roof installation services, energy audits, and roof repairs.

However, some customers have raised concerns about the pricing and quoting process. They found it confusing to determine the total cost of their system and experienced frequent back-and-forth over pricing.

Some customers also noted that Venture focuses on premium products, leading to higher pricing even when unnecessary. We found several Reddit threads discussing Venture where other solar customers and installers mentioned similar experiences.

Tesla Solar

4

Tesla is one of the few solar companies that provides potential customers with an up-front quote on its website. It offers a range of sleekly designed solar panels and shingles that blend into your existing roof. It also manufactures the Tesla Powerwall, one of the industry’s most popular solar batteries. There are a variety of price points for the Tesla Powerwall, depending on the model and where you live.

Tesla is one of the most popular solar brands in the industry, with 10% of our survey takers choosing its solar equipment.

How We Scored Tesla Solar

Tesla earned 4 out of 5 stars based on our rating scale. The company offers many industry-standard services, including solar roof installation. Unfortunately, Tesla earned some of the lowest point values for customer service and reputation. 

  • Solar Equipment and Services (18 out of 25 points): Tesla installs solar panels and shingles in addition to its Powerwall batteries. The company also earned points in this category for its active monitoring services.
  • Warranty and Performance Guarantees (16 out of 25 points): Tesla lost points in this category because it only offers a 10-year product and workmanship warranty, whereas most companies offer a 25-year product warranty.
  • Brand Reputation and Professional Certifications (5 out of 15 points): Tesla lost significant points in this category because it has a negative online reputation despite being a popular provider. It also doesn’t prioritize working with NABCEP-certified installers.
  • Financing Options (10.5 out of 15 points): Tesla doesn’t provide in-house financing and only offers full purchase and solar loan payment options. 
  • Industry Experience (7 out of 10 points): Tesla is one of the largest names in solar, but it only has 18 years of experience.
  • State Availability (8 out of 10 points): The company serves all 50 states.

Pros and Cons

Reputation and Reviews

Tesla began in 2003 as a subsidiary of Tesla, Inc., a leader in automotive manufacturing and electric vehicles. It grew its solar technology to include solar panels, the Tesla solar roof, the Tesla inverter, and the Tesla Powerwall, one of the industry’s most popular solar batteries.

Tesla has an A+ rating on its BBB profile but doesn’t hold accreditation. We noted that Tesla customers praised the company for its solar panel and Powerwall performances but flagged constant issues with scheduling repairs and servicing.

*BBB ratings are accurate as of May 2024. 

Note: In July 2024, SunPower notified dealers it would be halting all new shipments and project installations. The company also noted it would “no longer be supporting new Leases and PPA sales nor new project installations of these financing options.


Other Companies We Reviewed

The following companies didn’t make our list but are still worth considering.

  • LGCY Power: LGCY Power provides one of the best guided solar consultations and offers detailed online articles covering the solar installation process. The company also partners with Sunrun, one of our picks for top solar companies. 
  • Trinity Solar: Trinity Solar has served the Northeast for more than 28 years. The company’s in-house staff is certified by some of the solar industry’s most prestigious programs.
  • Elevation: Elevation takes a holistic approach to solar energy by offering entire home energy upgrades. The company provides solar systems, batteries, and energy audits to help you save on energy costs. The company also sells Curb Energy Monitoring devices to track energy usage and control smart devices in your home.
  • Green Home Systems (GHS): GHS installs high-efficiency solar panels and solar shingles that blend in with your roof. We like the company’s solar roofing system because it’s a competitive option compared to Tesla’s solar roof.

Some companies didn’t make our list because we don’t recommend them to everyone. For example, Solar Is Freedom has limited services compared to other providers, and Vision Solar recently announced bankruptcy amid two lawsuits. We feel confident the providers suggested in our guide have solid bankability and top-tier service options.


Are Solar Panels Worth It?

Though expensive to install, solar panels are worth the investment for most users. They offer several benefits, including long-term cost savings and increased home value. Going solar also allows you to rely less on external electricity sources and gain protection from unforeseen disruptions in the power supply. Federal and state solar incentives help reduce initial installation costs, resulting in a better return on investment.

More than 3 million homes have reaped these benefits by converting to solar energy, with one million installations taking place in the last two years, according to the U.S. Department of Energy.

  • Roughly 96% of solar customers we surveyed said they felt making the switch to solar power was worth it, and 82% said their installation increased their property value. 

How Much Do Solar Panels Cost?

Most U.S. homes require around a 10-kilowatt (kW) system, which costs an average of $31,460 before applying solar incentives. A 10-kW system is generally a large enough system to power a 2,000-square-foot house. You can greatly reduce your solar panel costs by applying for solar incentives, such as the federal tax credit, net metering, or local rebates. The federal solar tax credit alone allows you to recoup up to 30% of what you paid for your system on your income taxes. The average payback period, meaning the time it takes for your energy savings to be equal to your investment, is eight to nine years. 

How Long Do Solar Panels Last?

The Department of Energy says that quality solar panels last 30–35  years if well-maintained. Most come with a warranty of 25–30 years. Technically, your panels can last far longer, though energy production will likely decline, so they won’t generate as much electricity to power your home as they once did.
