Below is how the top installers compare, what a system really costs in 2026, and how to pick without overpaying.

How we ranked the best solar companies

Three things separate a great solar company from an expensive mistake: price per watt (the apples-to-apples cost metric), warranty depth (equipment, workmanship, and production guarantees), and who actually shows up (in-house crews vs. rotating subcontractors). We weighted installers on those factors plus financing flexibility, coverage area, and post-install support.

The 7 best solar companies of 2026

1. Sunrun — best for leasing and $0-down

The largest residential installer in the country, Sunrun is strongest if you want a lease or power-purchase agreement with little money down. You trade some long-term savings for a hands-off arrangement where Sunrun owns and maintains the panels. Best for homeowners who want predictable monthly payments over maximum ROI.

2. Tesla Solar — best for price per watt

Tesla consistently posts some of the lowest advertised prices per watt in the industry and pairs panels cleanly with the Powerwall battery. The trade-off is a largely online, lower-touch sales and service experience. Best for cost-focused buyers who are comfortable with a streamlined process.

3. Palmetto — best for service and monitoring

Palmetto combines competitive pricing with a well-reviewed app and an optional protection plan that covers monitoring and maintenance. Its network model keeps installs local. Best for homeowners who want strong ongoing support after the crew leaves.

4. Freedom Forever — best warranty coverage

Freedom Forever backs systems with a 25-year production guarantee alongside equipment and workmanship warranties, and operates through a wide installer network across many states. Best for buyers who prioritize long-term guarantees.

5. Momentum Solar — best full-service experience

Momentum handles design, permitting, and installation in-house in the markets it serves, which tends to smooth out the process. Pricing runs a bit higher than budget options. Best for homeowners who want one accountable company end to end.

6. Elevation — best for whole-home energy efficiency

Elevation pairs solar with energy-efficiency upgrades and home energy monitoring, aiming to cut consumption before sizing the array. Best for owners who want to lower usage, not just offset it.

7. A vetted local installer — best value in most markets

National brands are convenient, but a licensed, well-reviewed local installer frequently beats them on price and responsiveness because their overhead is lower. Best for homeowners willing to get quotes and check licensing, reviews, and NABCEP-certified staff.

What does a solar system actually cost in 2026?

Residential solar in 2026 typically runs about $2.50 to $3.50 per watt installed before any incentives. A common 6-to-11 kW home system therefore lands roughly in the $15,000 to $33,000 range gross, with 8 kW near the middle.

A federal residential clean-energy tax credit has historically covered 30% of the cost, and many states add rebates or performance incentives — but these programs have been changing recently, so confirm current eligibility and deadlines for your state before you sign. Between the federal credit and local incentives, net costs are often meaningfully lower than the sticker price.

Key cost drivers: roof complexity and pitch, panel efficiency tier, whether you add battery storage (a battery can add $10,000-$20,000), and local labor and permitting.

How to choose the right solar company

Get at least three quotes and compare price per watt, not just the bottom-line number, so you can compare systems of different sizes fairly. Then check five things: the installer's state license, whether crews are in-house or subcontracted, the length and terms of the equipment/workmanship warranties, the production guarantee, and independent reviews. Be skeptical of high-pressure "today only" pricing and of quotes that bundle financing fees into an inflated cash price.

Ownership beats leasing for most homeowners who can use the tax credit, because you keep the incentives and the full long-term savings. A lease or PPA makes sense mainly when you can't use the credit or want zero upfront cost.

Bottom line

There is no single best solar company for everyone — the right pick depends on which installers serve your ZIP code, whether you're buying or leasing, and how much hands-on service you want. Start with two or three of the names above plus one strong local installer, compare on price per watt and warranty, and verify current incentives before you commit.
