Why verify a California solar installer?

Solar installations involve electrical, structural, and roofing work — all under one job. Confirm your solar installer is properly licensed for every part of what they're proposing.

How to hire a California solar installer safely

  1. Verify the installer holds an active electrical or solar contractor license in your state.
  2. Confirm they will pull both electrical and building permits — required everywhere.
  3. Ask whether the installer (not a salesperson) is NABCEP certified — the industry's gold standard.
  4. Get a written warranty: 25 years on panels, 10+ years on inverters, 10+ years on workmanship.
  5. Insist the contract spells out interconnection (utility approval) and post-install inspection in writing.

Most states require a C-46 Solar contractor license, an electrical contractor license, or both. Some states also require a separate roofing license if attachments penetrate the roof.

How long does a solar install take?

Physical install is 1–3 days. Total project time, including permitting, utility interconnection, and inspection, is typically 6–12 weeks from contract signing to power-on.

Are solar installers responsible for roof damage?

Yes — a licensed solar installer's workmanship warranty covers roof penetrations they create. Always confirm this in writing before installation.
