SunPower earned House Method’s recognition as the best overall solar company. With more than 35 years of experience in the industry and 16,000-plus employees across all 50 states, this is one of the most experienced providers you could use for any solar energy need. It provides a range of monocrystalline panel options for residential applications.
SunPower offers full installation for all panels it provides. You’ll also have access to a full monitoring system for your panels via a mobile app. Aside from conventional installation and maintenance for the panels we’ve listed below, you’ll be able to get the following from this company:
SunPower has moved towards almost entirely in-house solar panels. Its offerings include using Maxeon cells, which provide greater energy output per panel.
SunPower offers a 25-year warranty for all solar panels it installs. Clients are afforded easy tracking of solar panel efficiency through a mobile interface that SunPower technicians will help to set up.
The average cost of a SunPower 5kW system will range between $11,500 and $41,000. This equates to between $2.23 and $9.22 per watt. Costs such as these are calculated before in-state incentives or the federal tax credit are applied, so your costs will vary.
SunPower offers the following options for purchasing solar power: Full purchase, financing, and solar lease. With either financing a solar loan, you’ll be able to defer much of the cost through a payment plan. You’ll still be treated to reduced costs but must make monthly payments on your loan. However, with a solar lease, SunPower retains full ownership of your panels, which you effectively rent via monthly payments.
SunPower partners with AAA to offer discounts which can vary by state. If you’re a AAA member in most states, you could be eligible for a $1,000 Visa rewards credit if you get your solar power from SunPower.

Tesla Solar is one of the most prominent providers of solar panels and solar roofs in the United States today. With plenty of low-profile solar shingles and solar panel options and name recognition worldwide, it is an increasingly popular option among homeowners. Tesla offers many services at a high level, either directly or through its Certified Installer Program across the states in which it operates. No matter where you’re located within its service area, you’ll have access to high-efficiency solar energy and qualified installation assistance.
Tesla Solar uses installation contractors to provide a typical range of installation and maintenance services for its systems. These include:
Tesla manufactures its own solar panels, solar roof, and solar battery, the Powerwall.
Tesla offers a comprehensive 10-year product warranty for all solar system components. It covers defects or issues with your battery, panels, or inverters, as well as roof leaks or mounting problems.
Along with this, you’ll be afforded a 25-year performance guarantee. It states that if your solar panels fall below 80% maximum capacity for power production during this time, you’ll be entitled to free repairs or replacement. While this somewhat lags behind other solar providers’ guarantees, it does offer some protection.
Tesla solar panels feature a low-profile, sleek design and are meant to be an accent piece to an existing roof, aside from providing energy-efficient electrical solutions. You’ll be able to purchase Tesla panels in four differently-sized packets, which are priced as follows:
These price points do not reflect potential tax incentives, which will differ depending on your location. For the 12-panel system, you could expect to pay between $13,000 and $15,000 after these have been applied.
If you opt for a solar roof from Tesla, your minimum price point will be around $75,000 before incentives. A Tesla Powerwall battery for on-site energy storage can be purchased but will inflate your price far more.
Tesla solar offers two options for purchasing one of its solar panel systems. These include financing and outright purchase. You’ll have to inquire about costs and down payment requirements when you get your in-home inspection from this provider. However, regardless of your choice, Tesla’s price-matching option makes for competitive rates.
Tesla Solar is available across all 50 states, but availability varies by ZIP code.

Momentum Solar was founded in 2009 and is our pick for the industry’s best customer service and installation labor.

With Momentum Solar, you’ll be afforded access to quality solar components from top industry manufacturers, attentive labor, and system monitoring for the lifetime of your solar system.
Momentum’s somewhat limited reach is balanced by its qualified in-house installation teams. When you book with Momentum Solar, you’re guaranteed to have one.
Momentum Solar exclusively uses high-quality monocrystalline solar panels for all residential applications. These panels offer the highest available energy efficiencies and temperature tolerances on the market today.
It has also begun using Enphase micro-inverters and solar batteries for all similar projects. Along with sturdy hardware and components, these ensure a long-lasting system.
Momentum Solar provides two separate 25-year warranties. They cover:
Your cost for a 5kW solar energy system with Momentum Solar will likely fall between the industry average of $22,000 to $33,000. This provider doesn’t post much of its pricing information on its website. You’ll be able to get a quote by scheduling an in-home consultation and evaluation from a Momentum Solar expert.
Momentum offers customers the ability to purchase their home solar systems outright, as well as solar leases, solar loans, and Power Purchase Agreements (PPA). A PPA involves paying your solar company instead of your local utility company. The amount you pay will depend on the energy production of your system.
Momentum Solar is available in 11 states, which include:

The professionals at Sunrun are well aware of how expensive the startup costs can be when going solar and are prepared to help. This provider’s leasing and financing options make it far more accessible to the average homeowner looking to go green with their home energy needs.

Trinity Solar is one of the most experienced solar installers in the industry, doing business throughout the eastern United States since 1994. The company’s main draw is its fast installation, performed by experienced installers certified by the North American Board of Certified Energy Practitioners (NABCEP). Installation sometimes takes a single day to complete. Trinity offers a solid selection of high-quality solar panels from top brands and offers flexible financing options, making it easy to find the right plan for your financial situation.
Trinity Solar offers no-cost solar installations, which makes it easier than ever to afford to make the switch to solar power. The company handles the entire process for you, from handling permits to designing your system and performing the installation in-house. Trinity will also help you find the right financing option to reap the financial benefits of residential solar.
Trinity provides panels, battery backups, and inverters from the industry’s leading brands, including Q Cells, SolarEdge, Tesla, and Generac.
One of Trinity Solar’s weaknesses is its warranty, which covers equipment for 12 years and workmanship for just five years. The industry’s best warranties cover both equipment and workmanship for 25 years, making Trinity’s warranty look unattractive by comparison.
Unfortunately, Trinity Solar doesn’t publish its pricing on its website. You can expect to pay between $22,000 and $33,000 for a typical 5 kW system. The variation in cost is due to differences between panel brands, home size, and other factors unique to your region and home.
Trinity Solar offers monthly leases, full leases, solar loans and full purchase options.
Trinity Solar’s Headquarters is located in Monroe Township, New Jersey, with service available in the following states:

Vision Solar is a newcomer to the solar space. The company was founded in 2018 in Blackwood, New Jersey but has quickly gained popularity in the states where it’s available. Despite its limited service area, Vision Solar offers a decent selection of equipment and solar services from leading brands.
Vision Solar’s services are somewhat limited. Unlike some companies that offer battery backups, electric vehicle (EV) chargers, and system monitoring, Vision Solar only offers basic solar panel installations.
Vision Solar partners with Enphase, SunPower, and other undisclosed tier-one panel manufacturers.
Though it is unusual for a solar company not to offer a workmanship warranty, Vision Solar doesn’t offer warranties on any purchased solar systems beyond the coverage provided by the manufacturer. However, Vision Solar handles all repairs and replacements if you enter a PPA with the company.
Vision Solar doesn’t make its pricing information available on its website, so you’ll have to contact the company and schedule a free quote for specific information. The national average cost for a 5 kW solar panel system is around $11,000, although most solar installers charge double or triple that price to cover installation and operating costs. That means you should expect to pay from $22,000–$33,000, on average.
Vision Solar doesn’t offer traditional leases, but it does offer PPAs, along with outright up-front purchase.
Vision Solar is currently available in the following states:

Freedom Forever has been in business for more than 10 years, bringing affordable renewable energy to residential customers since 2011. The company is primarily a residential solar provider, which means it’s accustomed to dealing with the unique challenges of installing rooftop solar and helping ordinary people change to solar power. The company has an excellent track record, boasting an A+ rating from the BBB and countless positive reviews online.
Freedom Forever doesn’t offer as many solar services as some competitors, but its services are solid. The company provides basic solar panel and battery backup installations from leading solar brands.
Freedom Forever produces its own solar panels in-house, a rarity in the solar industry. However, the company relies on industry mainstays like LG and Tesla to provide its solar batteries.
Freedom Forever relies on the manufacturer’s warranty to protect the equipment it installs, but it does offer a competitive 25-year warranty on production. The company’s Production Guarantee states that Freedom Forever will repair your solar system or reimburse you if it doesn’t perform up to the standards it sets during installation. This peace of mind is hard to come by and is one of the top reasons to go with Freedom Forever.
Estimating Freedom Forever’s average cost is difficult due to its large service area. The national average cost of solar installations is just under $3 per watt, but the variance between regions is high. You should expect to pay between $15,000 and $25,000 for an average-sized solar panel system from Freedom Forever. If you also want a battery backup, you should pay an extra $7,000–$14,000.
However, contacting the company for a free quote is the only way to get an accurate price for your home.
Freedom Forever offers full purchase, fixed-rate monthly leases, PPAs, and solar loans.
Freedom Forever is available in the following 25 states:
Arizona | California | Colorado | Connecticut | Delaware | Florida | Georgia | Idaho | Illinois | Maryland | Massachusetts | Nevada | New Hampshire | New Jersey | New Mexico | North Carolina | Oregon | Pennsylvania | Rhode Island | South Carolina | Texas | Utah | Vermont | Virginia | Wisconsin

NRG Clean Power has been around since 1987, providing top-notch solar installation services backed by industry-leading guarantees for more than two decades. The company only serves Texas and California, but its limited service area has allowed it to become an expert on the nuances of installing rooftop solar panels throughout the desert southwest. NRG Clean power offers an impressive lineup of solar panels and batteries from virtually every top brand and stands behind its work with a 25-year comprehensive warranty.
The company offers solar panel and battery backup installations.
The company carries equipment from an impressive number of leading solar equipment manufacturers, including the following:
NRG Clean Power’s warranty is among the best in the business. The company covers equipment—panels, inverters, roof mounts, and batteries—for 25 years. It also offers a performance guarantee that provides compensation for underperforming systems for up to 25 years. This warranty and performance guarantee is outstanding and sets NRG Clean Power apart from most other solar companies.
NRG Clean Power doesn’t publish its pricing information on its website, preferring to deal with customers directly in personalized meetings. This makes it slightly more difficult to compare the company’s prices with other solar providers, but the wide range of products and brands NRG Clean Power offers makes it hard to estimate general costs anyway.
The national average cost of a 5 kW solar system is about $11,000, although most companies charge 100%–200% more for installation to cover operating costs. This means you should expect to pay around $22,000–$33,000 for a 5 kW system from NRG Clean Power
One of the only negative things we have to say about NRG Clean Power is that it doesn’t provide specific information about financing on its website. The company states that it offers several financing options but offers no details, making it difficult to know if it has a financing plan that works for you.
Most solar companies offer cash purchases and loans, with some also offering PPAs and leases. Unfortunately, you’ll have to contact the company to see what options it offers in your area.

As with any major home renovation, you’ll have plenty to consider before opting for solar energy or choosing a solar panel installation company. Total cost, quality of the solar products or workmanship, tax credits, net metering or other incentives, and more will go into your final decision. We’ve outlined the major areas of concern here.
Each solar power system should ideally be tailored to your home. As a homeowner, you’d do well to get consultations from multiple solar companies before deciding on the best option. Services offered can include:
Each solar company will offer slightly varied energy solutions. Not all renewable energy brands are created equal, and the solar company that manufactures your panels could dictate how well your system functions over time. Brands like LG Solar, LONGi Solar, SunPower, and more should be at the top of your list for quality.
The average cost of having a solar energy company install solar panels for a 2,000-square-foot home is between $18,000 and $22,000. Many states offer tax credits or incentives in other forms. Your particular solar system could also be eligible for rebates, depending on the solar panel manufacturer and company you use. This will all be calculated after the fact, however.
We recommend getting consultations from multiple local providers to get the most out of your full-service solar panel installation.
Many of the best solar panel and installation companies will offer built-in warranties for labor and equipment. Performance warranties for solar panels will typically guarantee 90% energy output for 10 years. Beyond that, a 25-year warranty will ensure 80% energy production. Beyond this, labor warranties will depend largely upon the provider you choose.
A solar system on your home can greatly reduce your energy bill in the right location, but you’ll be faced with high startup costs. As a result, many homeowners looking to go solar ask about financing options. Here are your standard purchasing options:
Before signing any contract for your solar panel installation, you must ask questions and look at the contract’s fine print. Some solar panel providers contract out labor and installation services to third parties. While many providers offer in-house labor and installation, your particular situation may differ. This could, in turn, affect labor warranties and overall solar panel system quality. Ask about the installation process and whether your company offers labor warranties.
Customer feedback should be a big differentiating factor between different solar industry providers when researching. Look through solar reviews before getting in-home consultations. Look for indicators that point to the quality of products a given company installs, the quality of labor, and the ease of working with a provider. Factors like customer support and the friendliness of the assigned labor crews should come into play here. Google, Yelp, social media, BBB ratings, and more such platforms will be helpful.
Company size, including the number of locations, number of employees, and qualified technicians, could influence your purchasing decision. Beyond the installation process, your solar company’s size could play a factor if you require future maintenance. Most solar panel companies will offer free or reduced-cost maintenance for a certain period after installation. The company size could determine how quickly it can assist you in an emergency.
With so many companies popping up in the solar industry, choosing an installer that fits your budget and still provides the quality products and service you’re looking for can be challenging.
After extensive research, we recommend any of the ten installers reviewed above for your solar project. These providers offer outstanding warranty coverage, great customer service, a good selection of equipment brands, and years of experience, all for relatively affordable prices.
California, Massachusetts, Arizona, Hawaii, and Nevada are the most solar-friendly states. Our in-house team conducted thorough research on this topic, which took state solar usage, tax incentives, and the total percentage of solar energy use into account.
This study by The U.S. Department of Energy at Berkeley Lab showed that prospective buyers would be willing to pay $15,000 more for a home with a solar roof or solar panels installed. Given that this study concluded in 2013, this figure would now be at least $18,690, keeping with inflation.
Monocrystalline solar panels have shown themselves to have superior heat tolerance, as well as model efficiency ratings. This makes them a fantastic option for desert climates and other areas that receive a fair amount of sunlight. Efficiency ratings for such panels are often between 20% and 22%, placing them in the upper echelon among all solar panels.
Solar energy systems average efficiency ratings between 10% and 15%. This means that, through the panel and accompanying micro inverter, the total amount of usable electrical output totals about 10% to 15% of the energy received from direct sunlight. Even with what looks to be a low efficiency rating, this can still reduce energy costs by up to 90% to 95% if you live in an area with high sun exposure.
Ideally, you’d like to have at least four hours of direct sunlight daily to ensure maximum output. However, your panels won’t need direct sunlight to produce energy. They will work with indirect sunlight and at a lower output during cloudy days.
A solar consultation will help determine whether your energy needs mesh well with your location. Supplemental energy from the existing power grid could be needed if you don’t receive enough direct sun. However, a good battery storage system could solve your problems.
At House Method, transparency and trust are our most important values for the reader. That’s why we took the time to create an objective rating system and score each solar energy company/service according to our methodology.
Our research team dug deep into the fine print of contracts, combed through more than one hundred customer reviews, and thoroughly investigated each solar energy company’s services, costs, and products. We’ve done the homework for you by researching nearly all the solar energy companies on the market so you can have the information you need to make the best choice for your home.
We developed a formula to objectively determine the best solar energy companies and give each a score out of 100 based on the following criteria:
