Email is the only way we handle enquiries, and every message goes to one inbox:

We read everything and aim to reply within two business days.

If your company appears in our rankings

Rankings are computed from public installation records that utilities and state agencies report to Berkeley Lab's Tracking the Sun dataset. We can't change those records, but if your company's name is wrong, two companies have been merged under one name, or your company is shown as closed by mistake, email us and we will correct how we read them.

If you believe your company shouldn't appear at all, write from an address at your company's domain and explain why. We review every request.

If you found an error

A company that has closed, a wrong company name, a figure that does not match its source — please tell us which page and what is wrong. Corrections are the most useful email we get.

What we cannot help with

We are a directory, not a solar contractor. We cannot quote a system, service equipment, handle a warranty claim or intervene in a dispute with a company listed here. For those, contact the company directly, or your state contractor licensing board if the issue is unresolved.
