SolarGeng publishes independent reviews of U.S. residential solar installers, panels, and battery systems. Our goal is simple: help homeowners cut through marketing claims and understand what they are actually buying. Here is how we evaluate every company we cover.
What we evaluate
- Cost & transparency – how pricing is presented, the quote process, and whether costs are clear before you sign.
- Equipment quality – the panel and inverter brands offered, their efficiency, and durability.
- Warranties – workmanship, equipment, and production guarantees, and who actually honors them.
- Financing – cash, loan, lease, and PPA options, and how each affects long-term value.
- Installation & service – in-house versus subcontracted crews, timelines, and post-installation support.
- Reputation – verified customer feedback across the BBB, Google, and Trustpilot, including how complaints are handled.
Our sources
We combine public company information, manufacturer specifications, and aggregated customer reviews from independent platforms. We weight recurring themes more heavily than isolated comments.
How we score
Each company receives an editorial rating out of 5 based on the criteria above. Ratings reflect our independent analysis, not paid placement – SolarGeng does not sell ranking positions.
Reviews are written and maintained by Evan Caldwell, who has over a decade of experience analyzing the U.S. residential solar market.
