Solar & Battery Installation in Rancho Cucamonga, CA
Served from our nearby Ontario office, Rancho Cucamonga homes get fast, in-house solar and battery installs.
What going solar looks like in Rancho Cucamonga
Rancho Cucamonga homes are served by Southern California Edison (SCE), and permits run through City of Rancho Cucamonga. We manage both for you. Under NEM 3.0, the smart play here is solar sized to charge a battery, so you run your home on stored solar during the expensive evening peak instead of buying power at top rates.

Solar designed around Rancho Cucamonga
We design and install across Rancho Cucamonga — including Alta Loma, Etiwanda, Terra Vista, Victoria, Cucamonga, and Red Hill.
Climate & energy use
Rancho Cucamonga sits on the alluvial plain below the San Gabriel Mountains, so it runs a hot-summer Mediterranean climate with long, dry summers and heavy daytime cooling loads that often peak well after the sun has dropped. Pairing solar with a battery lets that production carry a home's late-afternoon and evening air-conditioning instead of buying it back from the grid at peak prices, and it keeps essentials running during the fall Santa Ana wind events that periodically threaten the foothill, wildland-urban-interface neighborhoods with outages and fire weather.
Roofs & housing stock
Much of the city's housing stock is Mediterranean-inspired tract and master-planned homes from the late 1970s through the 1990s, so concrete and clay "S" tile roofs with stucco exteriors are very common, alongside composition shingle on newer and infill builds. Tile calls for tile-specific flashing and hooks and careful handling to avoid breakage, while the foothill hillside lots up in Alta Loma can add slope and shading factors we account for in the layout.
HOA & design review
Many Rancho Cucamonga homes sit in master-planned communities like Terra Vista and Victoria with active HOAs and architectural review, and we handle those submittals and approvals as part of the install.
