For a small slice of San Diego County homeowners, rooftop solar might suddenly cost next to nothing. The county is rolling out a limited pilot that lets income-qualified owners in unincorporated communities install rooftop solar with little to no out-of-pocket cost. The San Diego Solar Equity Program - County Pilot sets aside just 22 project slots and is designed to knock down the steep upfront price that often stops households at the door. County officials say the incentives are sized to cover typical installation expenses for qualifying homes.
How the pilot works
The county describes the pilot as offering incentives of up to $4 per watt, intended to cover 100% of installation costs for many systems, and expects to support roughly 22 residential installations in this single application cycle. The pilot is funded with a federal Energy Efficiency and Conservation Block Grant and will be administered locally to prioritize disadvantaged unincorporated neighborhoods, according to the County of San Diego.
Who qualifies
The program focuses on owner-occupied single-family residences, including mobile and manufactured homes, where household income is under 120% of the Area Median Income and the property is located in a disadvantaged community as defined by federal screening tools. The pilot opened to applications in mid-November 2025 and comes with a limited incentive pool of about $440,000 for solar incentives plus $20,000 set aside for panel upgrades, according to the program FAQ at SD Solar Equity Program.
How to apply and the fine print
Homeowners must work through an eligible solar contractor listed on the program site. Contractors submit reservation requests and the nonprofit Center for Sustainable Energy reviews applications on a first-come, first-served basis. Incentive payments are released only after installations are complete and SDG&E issues Permission to Operate, and approved projects must be finished within 12 months. For local contact details, the county lists America Aceves in Planning & Development Services, [email protected], on its program page, according to the County of San Diego.
Why this matters
Rooftop solar can chip away at household energy costs at a time when local utility bills have been climbing, with the typical SDG&E customer’s monthly bill nearing $200 in early 2026. The county pilot builds on a larger SD Solar Equity Program launched with SDG&E funding and is meant to test how a targeted incentive model works outside the city. Local reporting and utility program materials lay out the equity goals and funding behind these efforts. See coverage from KPBS and program details from SDG&E.
Spots in the county pilot are limited and reserved on a first-come, first-served basis, so eligible homeowners might want to move quickly. Residents can review requirements, find the list of eligible contractors and access reservation forms at the program website.
