GoGreen Home loans in California: rates, terms and who qualifies

A heat pump, a panel upgrade or new insulation can cost thousands of dollars, and many people put that on a credit card or a short personal loan. California has a lesser-known option built for exactly this: GoGreen Home, a state program that helps lenders offer lower-rate, longer-term loans for energy upgrades.

How it works. GoGreen Financing sits in the California State Treasurer's Office and was created by the California Public Utilities Commission in 2013. The state does not lend the money. Participating lenders, mostly credit unions, make the loans, and the program backs them with a loan loss reserve that covers most of the loss if a borrower defaults. That backing is what lets lenders offer better terms and approve a wider range of borrowers.

What it pays for. Examples on the program's site include attic insulation, high-efficiency heating and air conditioning, EV chargers, and solar panels with battery storage. The City of Palo Alto's program page also lists heat pump water heaters, induction ranges and ENERGY STAR appliances, and says required work such as an electrical panel upgrade can be financed too. Palo Alto's page also notes that up to 30% of the financed amount can go to non-energy "bonus" upgrades; check with your lender whether the same rule applies to you.

Rates, terms and amounts. Terms run up to 15 years, or up to 20 years if the project includes solar. The program's lender chart, with rates as of March 2, 2026, lists six statewide credit unions offering loans up to $75,000 at APRs ranging from 3.58% to 9.48%. Several regional credit unions offer similar loans in their own areas. Rates change, so treat these as a snapshot.

Who qualifies. The program covers single-family homes, condos, townhouses, mobile and manufactured homes, and buildings of up to four units. There is no lien on your property, renters and lessees can use it, and the lender chart says credit scores starting as low as 580 can qualify.

Example: a $15,000 heat pump. These numbers are illustrations, not quotes. At 6% over 10 years, the payment is about $167 a month and total interest is about $4,980. At 6% over 5 years, the payment is about $290 a month and total interest is about $2,400. A longer term makes the monthly payment easier, but you pay more interest overall, so compare both.

Is it a scam? No. It is a state program. PG&E, SCE, SDG&E and SoCalGas logos appear on its site, but the utilities do not make the loans or review applications. Still, the loan itself comes from a lender with its own terms, so read them like any other loan.

Questions to ask before you sign: What is the APR, and is it fixed? Is there a prepayment penalty? Does the quoted rate assume an auto-pay discount? Does my contractor need to be a GoGreen participating contractor? Can a rebate I receive later be applied to the balance?

Today's step: get your contractor's quote in hand, then use the loan calculator and lender list at GoGreenFinancing.com to compare two lenders that serve your area.
