Choosing a solar installer is one of the biggest home-improvement decisions you can make, and the “best” solar company is rarely the one with the loudest ad — it is the one that is transparent on price, installs quality equipment, backs it with real warranties, and is reputable in your state. This hub gathers our independent, criteria-based reviews of the largest U.S. residential solar companies so you can compare them side by side.
Every review follows the same framework. See how we review solar companies for our full methodology — in short, we score each company out of 5 on cost & transparency, equipment, warranties, financing, installation & service, and reputation.
How to choose a solar company
- Get at least three written quotes and compare price per watt, not just the monthly payment.
- Favor ownership (cash or loan) over lease/PPA if long-term savings and resale matter.
- Confirm warranties in writing — workmanship length and any production guarantee.
- Check who installs — an in-house crew or a local partner — and read recent reviews in your state.

The bottom line
There is no single best solar company for everyone. The right choice depends on your state, your roof, and whether you value the lowest price, the strongest guarantee, or the best technology. Use the reviews above to shortlist two or three installers, then compare written quotes before you sign.
