Why Solar Is Getting Popular in the USA
I remember talking to a friend in Texas last year. He told me his electric bill dropped from $280 a month to almost nothing after going solar. That got me curious.
More and more Americans are installing solar panels on their roofs. Not because it is trendy. But because electricity prices keep going up and solar prices keep going down. That is just smart math.
The USA had over 4 million homes with solar panels in 2023. That number is growing fast. And with a 30% federal tax credit that was available through 2026, many homeowners saved thousands of dollars on installation.
But here is the real problem. There are hundreds of solar companies out there. Some are great. Some are not. And signing a bad solar contract can hurt you for 20 to 25 years.
That is why I spent a lot of time reading reviews, checking Reddit threads, and going through company details to give you this honest list of the best solar panel company in USA.
How Much Does Solar Cost in the USA?
Before picking a company, you need to know the basic numbers.
In 2026, the average solar installation costs around 3.50 per watt before any incentives. For a typical 6 kW home system, that works out to roughly 21,000 before the federal tax credit.
After applying the 30% Residential Clean Energy Credit (which was available through end of 2026), many homeowners paid around 14,700 for the same system.
A battery storage system like a Tesla Powerwall adds another 15,000 on top of that.
Over 25 years, most solar owners save between 148,000 on electricity bills depending on where they live.
Now, let us look at who you should buy from.
Top 20 Best Solar Panel Companies in USA
1. Sunrun
Founded: 2007 | HQ: San Francisco, CA | States: 20+
Sunrun is the biggest residential solar company in the USA. They serve over 500,000 homes and are known for making solar affordable through leases and power purchase agreements (PPAs).
What they offer:
- Solar panels from LONGi, Tesla, and other top brands
- Brightbox battery storage
- EV charging for Ford F-150 Lightning
- Solar leases with $0 down
Average cost: Varies by location; lease starts as low as $6/month for the first months.
What Reddit and users say: Honestly, Sunrun gets mixed reviews. Many users praise the low-cost lease option. But a lot of people on forums complain about pushy sales tactics, poor customer service after installation, and subcontractors doing inconsistent work. About 60% of reviews are positive. Around 25% are negative, mostly about slow service and warranty delays.
Verdict: Good if you just want $0 down and do not want to own the system. Not ideal if you care about customer service quality.
2. Tesla Energy
Founded: 2016 (formerly SolarCity) | HQ: Austin, TX | States: All 50 states
Tesla Energy is one of the most well-known solar brands in the world. They install solar panels, solar roof tiles, and the famous Powerwall battery. They also offer a price-match guarantee.
What they offer:
- Monocrystalline solar panels (now using Q Cells brand)
- Tesla Solar Roof (glass tiles that look like regular shingles)
- Powerwall battery storage (13.5 kWh capacity)
- Online quote tool and itemized pricing
Average cost: Among the lowest in the industry. A 6 kW system can cost around 17,000 before incentives.
What users say: Tesla is great for technology. Their Powerwall is considered one of the best batteries in the market. However, customer service after installation has been rated average to below average on many review sites. Some people wait a long time for service appointments.
Verdict: Good for tech-forward homeowners who want a clean, integrated setup. Not the best for those who need lots of hand-holding after installation.
3. SunPower
Founded: 1985 | HQ: San Jose, CA
Important note: SunPower filed for Chapter 11 bankruptcy in August 2024. They stopped offering new installations and financing. If you are an existing customer, you can still get system support. But new buyers cannot purchase from SunPower directly anymore.
We include SunPower here because it spent nearly 40 years as one of the most respected solar companies in the USA. Their Maxeon panels held efficiency records for over a decade. They offered a 25-year combined product, labor, and performance warranty, which no other company matched.
Their panels had up to 22.8% efficiency, which is among the highest for residential panels.
Verdict for new buyers: Look at alternatives. For existing customers, check SunPower's bankruptcy guidance for support options.
4. Momentum Solar
Founded: 2009 | HQ: South Plainfield, NJ | States: 12 states
Momentum Solar gives you a concierge-style experience. That means one person handles your project from start to finish, which cuts down on confusion.
What they offer:
- Tier 1 solar panels from multiple brands
- Enphase battery storage
- Financing, lease, and PPA options
- 25-year workmanship warranty for lease customers
Average cost: Similar to industry average, around 3.00 per watt.
What users say: Most reviews praise Momentum Solar's customer service. People like that they always speak to the same representative. The main complaint is limited availability since they operate in only 12 states.
Verdict: One of the better options for customer experience. Great if you live in their service area.
5. Blue Raven Solar
Founded: 2009 | HQ: American Fork, UT
Important note: Blue Raven was owned by SunPower and was included in the August 2024 bankruptcy filing. They stopped new installations at that time.
Before that, Blue Raven was well-regarded for its $0 down financing and no payments for 18 months offer. They had an A+ BBB rating and were praised for customer service.
Verdict for new buyers: No longer taking new projects. But their financing model was something many competitors copied.
6. Trinity Solar
Founded: 1994 | HQ: Wall, NJ | States: Northeast USA (NY, NJ, CT, MA, RI, PA, FL)
Trinity Solar is one of the oldest solar companies in the USA. They have over 30 years in the business, which is rare. They focus mostly on the East Coast.
What they offer:
- Solar panel installation with no upfront cost option
- Financing and lease options

Average cost: Competitive for the Northeast market.
What users say: Reviews are split. Some customers love their electric bill going down to under $5 a month. Others on Consumer Affairs have complained about poor communication after signing and some aggressive sales reps.
Verdict: Good track record and long history. Vet the local team before committing.

Verdict: A solid choice if you live in the New York area and prefer a local company over a big national chain.
9. Green Home Systems
HQ: New Jersey | States: Multiple
Green Home Systems focuses on solar plus battery storage packages. They specialize in helping homeowners understand the full system, not just the panels.
What they offer:

10. ADT Solar
Status: Exited residential solar business in January 2024.
ADT Solar was formerly known as Sunpro Solar. After ADT acquired Sunpro, they built a solid reputation with good warranties and quality products. However, ADT officially shut down its residential solar division at the start of 2024.
Verdict for new buyers: No longer available. Former customers should check ADT's transition support options.

What they offer:

Verdict: ION Solar does good work when it goes well. But delays are a real issue. Ask them for a specific timeline in writing before you sign.

Founded: 2011 | HQ: New Orleans, LA | States: CT, MA, MS, LA, NJ, PA

What they offer:

- Energy efficiency upgrades included
- GAF Energy panels
- Habitat for Humanity partnerships
Average cost: Lease starts at approximately $13,000 for purchased systems.
What users say: PosiGen has had a very difficult 2024 and 2026. Multiple customers reported systems installed but not activated for months. There are also reports that PosiGen went through financial restructuring, which has delayed projects.
Verdict: The mission is good and serves an underserved community. But the operational issues in recent times are a real concern. Verify their current operational status before signing.
15. Freedom Forever
Founded: 2011 | HQ: Murrieta, CA | States: 33 states + Puerto Rico

What they offer:
- 25-year production guarantee (85% for purchased systems)
- Multiple panel brands

What users say: The production guarantee sounds good, but reviews tell a different story. Many customers complain that the actual production fell short of promises and getting reimbursement is a battle. NerdWallet noted that Freedom Forever was on probation with California's Contractor State Licensing Board.
Verdict: The guarantee is attractive in theory. But verify everything before signing.
16. NextEra Energy

What they offer:

HQ: American Fork, UT | States: Nationwide (direct-to-consumer model)
Project Solar is different from all others on this list. They sell solar systems directly to homeowners at a much lower cost because they cut out the expensive door-to-door sales teams that add significant markup to every system.

- DIY-friendly kits or installer referrals
- No high-pressure sales
Average cost: Reported at 30 to 50% below typical national installer prices.

Verdict: Best for homeowners who have done their research, are not afraid to ask questions, and want to save serious money on their solar system.
Common Mistakes People Make When Choosing Solar
Choosing the lease without reading the contract. A 20 to 25 year lease can complicate selling your home. Some buyers do not want to take on someone else's solar contract.
Not getting three or more quotes. Solar prices can vary by thousands of dollars for the same system.
Focusing only on the panel brand. The installer's workmanship and warranty support matters just as much.
Ignoring customer reviews. Reddit, Consumer Affairs, and BBB reviews tell you what happens after installation. Read them.
Not asking about permits. Your installer should handle all permits. If they say you need to do it yourself, that is a red flag.
Tips Before Signing a Solar Contract
- Get at least 3 quotes from different companies.
- Ask for the exact brands of panels, inverters, and batteries they will use.
- Read the production guarantee carefully. Ask what happens if they miss the target.
- Check the BBB rating and look for recent complaints, not just the star rating.
- Ask about subcontractors. Some national companies outsource installations to local crews.
- Look up the company on Reddit. Real homeowners share honest experiences there.
Conclusion
Going solar is one of the smartest financial decisions an American homeowner can make today. But picking the wrong solar company is one of the easiest ways to ruin that decision.
From the research I did across review sites, Reddit forums, and company information, a few things are clear. Tesla Energy has the best technology. Momentum Solar has the best customer service. Freedom Solar Power is the top pick for southern states. And Project Solar is the best for budget-conscious buyers who do their homework.
SunPower, Blue Raven, and ADT Solar are no longer taking new customers, which is something many review sites still fail to mention clearly.
If I were choosing today, I would get quotes from at least three companies, read real reviews on Reddit and Consumer Affairs, and ask hard questions about production guarantees before signing anything.
The best solar panel company in USA for you depends on your location, your budget, and how much support you need after installation. Use this guide as your starting point, but always verify with local quotes.
