8 Best Solar Companies of 2024
Our team evaluated close to 100 U.S. solar companies based on reputation, solar services, payment options, state availability, and warranty coverage. Here are our picks for the best solar companies:
What Should You Know About Going Solar?
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, credits, and rebates allow you to save money when installing solar equipment. The federal government provides a 30% federal tax credit. Some solar companies assist you with finding and applying for solar incentives.
We also suggest you visit the Database of State Incentives for Renewables and Efficiency to view your area’s state and local incentives.
We surveyed 1,000 solar customers about their experiences getting quotes and installing solar panels. Most respondents (78.4%) used solar incentives to reduce their overall costs. A little over 75% of those respondents said the incentives they used were easy to access.
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.
How do I pay for solar panels?
You can choose from various solar financing options to fit your budget. 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.
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.

Are Solar Panels Worth It?
Though expensive to install, solar panels are worth the investment. 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.
How Do I Find The Best Solar Company in My State?
Some companies are available nationwide, while others have smaller service areas. Use our tool below to find which solar companies service your area.
What Should You Know About Solar Panel Equipment and Efficiency?
The solar equipment you choose plays a major role in your system’s performance and energy savings. Most homeowners choose rooftop installations to position their panels closer to the sun for optimal performance. You can add system upgrades, such as solar batteries, to extend your system’s functionality. Investing in high-efficiency solar panels will also help maximize your energy production.
Solar Panel Equipment
Below is an overview of typical installation options and upgrades.
- Traditional solar panels: Monocrystalline solar panels are the most common among homeowners. These panels offer the best efficiency and power output but are the most expensive. Polycrystalline panels cost slightly less but are also less efficient, so you must buy more panels to power your home.
- Solar shingles and roofing: Solar shingles and roofing provide the same structural protection as traditional roofing while also powering your home with solar energy. They offer a sleek, integrated design at a much higher price than traditional panels. For example, the Tesla Solar roof costs more than its traditional solar panels coming in at roughly $38,400 for a standard-sized system.
- Solar batteries: Most homeowners add solar batteries to their systems to maximize energy production and store backup power. You can use this stored energy when the power grid is down to keep your home running. We recommend considering a solar battery if you experience frequent outages or have medical equipment that requires power.
- EV chargers: Electric vehicle (EV) chargers offer a convenient at-home solution for EV owners. They use energy generated from solar panels to charge your vehicle at a lower rate than public charging stations.
How Do You Avoid Solar Scams?
Here are some tips for avoiding solar scams as you navigate the solar panel system buying process:
- Avoid individuals offering “free” solar panels: If you encounter a salesperson who claims you can receive free solar panels, this is a misleading sales tactic that is most likely trying to get you to lease a system.
- Don’t agree to pay up-front: Deposits are standard, but never pay in full until your system is installed, functioning properly, and has passed inspections.
- Purchase your system if possible: Scammers may highlight low costs by leasing the system, but you need to own your system to benefit from most solar incentives such as the federal solar tax credit. Paying in full typically provides the most long-term savings and helps you avoid untrustworthy providers.
- Read reviews: It’s important to conduct thorough research on each company you’re considering by checking third-party online reviews. Be cautious of any service provider with widespread negative reviews, complaints, or legal issues.
- Watch for aggressive sales tactics: High-pressure sales tactics, unsolicited calls, and door-to-door pitches are all warning signs of pushy salespeople who aim to persuade you to make impulsive decisions.
What Should You Expect During a Solar Installation?
You’ll typically meet with a representative to begin the installation process after you choose a solar provider. Here’s what to expect from this process based on our conversations with various installers.
A company representative will assess your property’s solar potential and determine your energy needs. Many companies offer in-person or virtual consultations. You’ll need your most recent utility bill to help determine your average energy usage. We recommend analyzing bills from several months to get the most accurate estimate.
The company representative will review your roof’s structural integrity, available space, slope, and shading. This helps determine the best location for your solar panels.
The rep will design a solar system to fit your needs with panels, components, and add-on accessory options. You’ll receive a finalized, detailed quote to approve. Most installers handle all necessary permitting and paperwork. The permitting process varies among areas but typically takes two to four weeks to complete. We recommend getting an estimated timeline for the entire installation process.
The solar company may use an in-house staff or third-party installers. To help avoid communication issues, we recommend asking for your project’s main point of contact. Most installations take one to two days, sometimes longer for complicated jobs.
Your solar company will coordinate with local officials for final activation approval. All installations must meet local codes and match the approved project designs. This process could take two to four weeks and depends on all parties’ availability.
Your system will receive permission to operate (PTO) once all parties approve the installation. The longest part of the installation is activation because you have to wait for local utilities to come out and put in a new meter. According to Matt Johnson, co-owner of Namaste Solar, “That’s something that can take a few weeks to a couple of months, depending on how backed up the utility is”. Your installer will connect the system to the grid and get final approval from the utility company for activation.
Which Solar Panel Installation Company Should You Choose?
Palmetto is our top-rated solar company due to its customized, high-performance, high-quality panels. You should consider Sunrun if you want excellent solar savings without committing to system ownership. We also like Blue Raven Solar because it provides competitive rates on high-efficiency systems and has one of the best financing programs for solar.
Consider your energy needs, budget, and local climate to determine the best solar energy company for you. We recommend getting multiple free quotes to compare costs, services, and warranty options.
FAQ About Solar Energy Companies
What are the disadvantages of solar energy?
The two main disadvantages of solar energy are the high initial cost and the dependence on weather conditions. Though solar panels are more affordable than ever, installing a solar energy system is still expensive. Additionally, the amount of energy a solar system generates can be affected by weather conditions such as clouds or storms, reducing the system’s overall efficiency and output.
Which is better: Sunrun or SunPower?
When comparing Sunrun vs. SunPower, the better option will depend on your needs. SunPower uses high-quality Maxeon panels paired with custom components to create high-performing systems. Sunrun offers unique leasing financing options that provide solar energy savings without buying your own system. Choose SunPower if having superior solar technology is a priority. Sunrun might be the better option for your home if you’re interested in energy savings without system ownership.
How much energy would solar panels produce?
Most residential solar panels produce between 250 and 400 watts of power. The higher the wattage, the more power your home receives. A solar installer will analyze your current electricity usage and determine the number of solar panels for your home. You can also use this calculator from the National Renewable Energy Laboratory to determine your solar panel size based on your energy usage.
Does homeowners insurance cover solar panels?
Yes, solar panels are covered under most homeowners insurance policies. This protection extends to damage caused by fire, wind, lighting, or other physical damage. Check your policy for complete details on your full coverage.
How easy is it to go off-grid for solar?
Going off-grid is considerably harder than investing in a traditional grid-tied system. The cost of an off-grid system is a much higher investment than a typical residential system, averaging between $45,000 and $65,000. They require more detailed planning for daily energy consumption to account for adequate energy storage needs. We recommend sticking with a grid-tied solar system unless your home is too far from traditional electric company power connections.
What Brand Has the Best Quality Solar Panels?
SunPower offers the most efficient and best performing solar panels, with efficiency rates reaching 22.8%, higher than the average of 15%-22%.
