The Short Answer
Yes — solar installations in West Covina require building and electrical permits. Excellent production, but NEM 3.0 changes the economics.
Apply through One Stop Portal at westcovina.gov or in-person at Room 215. Phone: (626) 939-8425. Building permit (racking) + electrical permit (inverter). CSLB C-10 or C-46. SCE interconnection under NEM 3.0. California property tax exclusion (R&T Code 73). SGIP battery incentive for SCE customers. ~5,500–5,800 kWh/kW annually.
West Covina solar permit rules — excellent production, NEM 3.0 economics
Solar PV installations in West Covina require a building permit (racking attachment) and an electrical permit (inverter interconnection), both through the One Stop Building Permit Center Portal or in-person at Room 215. Phone: (626) 939-8425. CSLB C-10 (Electrical Contractor) or C-46 (Solar Contractor) licensed contractors hold permits. After city inspections, the solar installer submits SCE's interconnection application under California's NEM 3.0 program.
California NEM 3.0 (Net Billing Tariff, effective April 2023) dramatically changed solar economics in California. Unlike the previous NEM 2.0, which credited exported power at near-retail rates, NEM 3.0 credits excess exported power at the "avoided cost" rate (approximately $0.05–$0.08/kWh in many cases) rather than the retail rate (~$0.35+/kWh for SCE customers). This ~75% reduction in export compensation makes oversizing systems for export less economical. The optimal NEM 3.0 system is sized to match the home's consumption (minimize export) and paired with battery storage to shift self-generated power to evening peak periods when SCE time-of-use rates are highest.
West Covina's excellent solar production (~5,500–5,800 kWh per kW annually from the inland San Gabriel Valley) combined with SCE's high electricity rates (among the highest in the nation) still makes solar economically compelling under NEM 3.0, particularly when paired with battery storage.
California Revenue & Taxation Code Section 73 excludes new solar installations from property tax reassessment. California's Self-Generation Incentive Program (SGIP) offers SCE customers rebates for battery storage systems installed alongside solar.

Common questions about West Covina CA solar permits
How do I apply for a solar permit in West Covina?
One Stop Building Permit Center Portal at westcovina.gov, or in-person at 1444 W. Garvey Ave S, Room 215. Phone: (626) 939-8425. Mon–Thu 7:30 AM–5:30 PM. Building permit (racking) + electrical permit (inverter). CSLB C-10 or C-46 licensed contractor.
What is California NEM 3.0 and how does it affect West Covina solar?
California's Net Billing Tariff (NEM 3.0), effective April 2023 for new SCE interconnections, replaced the prior NEM 2.0 program. NEM 3.0 credits excess exported solar power at the "avoided cost" rate (approximately $0.05–$0.08/kWh) rather than the retail electricity rate (~$0.35+/kWh). This approximately 75% reduction in export compensation changes optimal system design: systems should be sized to match the home's consumption (minimize export) and paired with battery storage to shift self-generated power to evening peak hours when SCE time-of-use rates are highest.
Is solar still worth it in West Covina under NEM 3.0?
Yes, particularly with battery storage. West Covina's ~5,500–5,800 kWh/kW annual solar production (excellent inland SoCal irradiance) combined with SCE's high electricity rates make solar economically compelling. Under NEM 3.0, the optimal system is sized to match consumption and paired with a battery to capture the value of avoided peak-rate purchases. Contact a CSLB C-46 or C-10 solar contractor for a site-specific NEM 3.0 financial analysis.
What is California's SGIP battery incentive for West Covina homeowners?
California's Self-Generation Incentive Program (SGIP) offers SCE customers incentive payments toward battery storage system installation. The program is administered by the CPUC and pays on a per-kWh basis for installed storage capacity. SGIP pairs very well with NEM 3.0 solar in West Covina: the battery stores excess daytime solar production and dispatches it during evening peak hours, maximizing the value of self-generated power.
Does California's property tax exclusion apply to solar in West Covina?
Yes. California Revenue & Taxation Code Section 73 excludes new solar energy system installations from property tax reassessment. The added value of the solar installation does not increase the assessed value of your West Covina home for property tax purposes.
