Is LumoWatt free for homeowners?

Yes. Browsing listings, comparing installers, and using the generator sizing calculator are all free.

How does LumoWatt check installers?

We confirm each installer's electrical contractor license is active on the state licensing board before they're listed, and re-check annually. See our listing standards and verification methodology for details.

Will my information be shared with multiple companies?

A quote request goes to at most 3 installers you choose, it is never blasted to a large list of companies.

Does LumoWatt install generators?

No. LumoWatt is a directory and comparison tool, not an installer. All installation work is done by the independent businesses listed here.
