Why choose Clean Energy USA, and why you might not

Reasons to look at others

Clean Energy USA reviews: what customers say
Each review site shows its own score; we read them on October 12 and 13, 2026 and do not combine them or add our own rating.

The five positive reviews below praise dedicated, responsive staff, quick activation with paperwork and permits handled, and help reconnecting an inverter’s monitoring, though one wished the instructions supported Macs. The three negative reviews describe calls and voicemails that went unreturned, including a reviewer still waiting weeks after an electrician visit about linking a generator to the solar inverter. These are issues to ask about, not a measure of how often they happen. Ask Clean Energy USA who returns service calls and how quickly.

How we picked these: the five newest 5-star and the five newest 1- or 2-star reviews with written text on Google and Trustpilot, as of October 2026 (161 reviews read, back to Mar 8, 2010). We found no Trustpilot page for Clean Energy USA on October 12, 2026. Each quote is one sentence, word for word. Picking the highest and lowest ratings shows the range of experiences; it is not a representative sample, and we did not verify what reviewers describe.
How much does Clean Energy USA cost?
Clean Energy USA does not publish its own system price; its residential FAQ gives only a general average range for home solar. Ask for an itemized quote showing the cash price, system size and equipment models, and how any state program or loan changes what you pay. For state price ranges, see our solar panel cost guide; for how the plans compare, see loans, leases and PPAs.
State-backed loan (Green Grant Delaware)
You own itA low-interest state loan program named on its incentives page. Terms are set by the program, not the company.
Low- to Moderate-Income Solar Program
Ask who owns itA state program for qualifying households, named on its incentives page. Ask who owns the system and what you must sign.
Programs as listed on Clean Energy USA’s residential incentives page, read October 13, 2026. The site lists no company loan, lease or PPA.
Clean Energy USA does not name the panel, inverter or battery brands it installs on the pages we read. Its customer service page gives support help for Fronius, Enphase, SMA and SunPower inverters, and it also installs Span smart electrical panels and EV chargers. Your written proposal should list the exact panel, inverter and battery models, the system size in kilowatts (kW) and the forecast yearly production in kilowatt-hours (kWh).
