Solar & Battery for IID Customers

No. CPUC NEM 3.0 applies only to California's investor-owned utilities (SCE, SDG&E, and PG&E). Imperial Irrigation District is a public irrigation and electric district governed by its own Board of Directors, and it operates an independent Net Billing tariff across La Quinta, Indio, Coachella, Bermuda Dunes, Thousand Palms, and Imperial County. Under IID Net Billing, electricity your home consumes directly from your solar panels or battery avoids IID's full retail rate (Schedule D plus Energy Cost Adjustment), while excess electricity exported back to the grid is credited at IID's published wholesale export compensation rate.

The Coachella Valley splits between IID in the east and SCE in the west. La Quinta, Indio, Coachella, Thermal, Mecca, and Bermuda Dunes are served by Imperial Irrigation District (IID). Palm Springs, Cathedral City, Rancho Mirage, Desert Hot Springs, and most of Indian Wells are served by Southern California Edison (SCE), while Palm Desert splits along Washington Street / Hovley Lane (mostly SCE west of Washington, IID in eastern pockets). We verify your exact utility meter and rate schedule on every quote.

For most Coachella Valley homes on IID, pairing a battery like Tesla Powerwall 3 (13.5 kWh usable, 11.5 kW continuous output) with rooftop solar improves both monthly savings and outage resilience. Because IID's Net Billing credits exported kilowatt-hours below the retail rate you pay to import power — and desert air conditioners keep running through 95°F–105°F evenings long after the sun sets behind the San Jacinto Mountains — storing your midday solar in a battery lets you self-consume your own generation overnight instead of selling it cheap at noon and buying retail power after dark.

OC Solar handles both pipelines end-to-end with in-house teams. Your project requires a city or county building and electrical permit (City of La Quinta, City of Indio, City of Coachella, or Riverside County PLUS) plus an interconnection application and production meter/disconnect review through IID Customer Generation. Our team engineers the heat-derated single-line diagram, pulls the city permit, installs the system with in-house B, C-10 & C-39 crews, passes city and IID field inspections, and secures final IID Permission to Operate (PTO).

The federal residential tax credit (IRC §25D) for homeowner cash and loan purchases expired on December 31, 2025. In 2026, IID homeowners can still capture the ~30% federal commercial tax credit (IRC §48E) pass-through via our Prepaid Solar Plan or a low-rate Lease/PPA where the commercial financing partner owns the system and builds the tax credit directly into your lower upfront or monthly cost. Income-qualified IID households may also check IID's REAP (Residential Energy Assistance Program) and tree/efficiency offerings.
