How we rank installers in California
Installers on this page are ordered by the number of installations we have on record for them, then by customer rating. Paid installer memberships do not affect the order.
The installation records come from public utility and state solar program filings and from quotes homeowners upload to AgentSolar. We match each record to the installer named on it, so a company's count reflects work we can actually attribute to them, not a claim on their website.
Prices are computed from cash and loan purchases only. Leases and PPAs are excluded because their per-watt figures are financing terms, not equipment prices, and each figure above states how many quotes it was drawn from.
How to choose a solar installer in California
Is the price in the normal range?
The middle half of recent California installations came in between $2.50 and $3.30 per watt for the solar array. A quote well above that range deserves a second bid. One well below it deserves a closer look at the panels, the inverter and the warranty — the cheapest quote is often the one that has cut something you will notice in year eight.
How many systems have they actually installed?
Every profile linked above shows the installations we can attribute to that company from public records and homeowner uploads. A long track record in California specifically matters more than a national brand name: permitting, utility interconnection and roofing norms are local, and a crew that has done hundreds of them here has already made the mistakes on someone else's roof.
Are they licensed and insured in California?
Ask for the contractor license number and confirm it with the state licensing board yourself, and ask for a certificate of insurance that names you. Where we hold a license number for an installer it appears on their profile, but a number on a website is not the same as a current, active license.
What do the warranties actually cover?
Most quotes carry three separate warranties, and they are easy to conflate. The workmanship warranty covers the installer's own labor, including roof penetrations, and is only as good as the company standing behind it. The product warranty comes from the panel and inverter manufacturers and survives the installer going out of business. The production guarantee promises a minimum energy yield and usually has conditions attached. Get the length of each in writing.
Do they install with their own crews?
Some companies sell the system and subcontract the installation. That is not automatically worse, but you should know who will be on your roof, who takes a warranty call in year five, and whether the workmanship warranty is the seller's or the subcontractor's.
Cash, loan, lease or PPA?
With a cash or loan purchase you own the system, and the prices on this page are those purchases. With a lease or a power purchase agreement a third party owns it and you pay monthly for the equipment or the electricity. Compare the total cost over the contract term rather than the first monthly payment, and check what happens to the agreement if you sell the house.
