Solar & Battery Installation in Ontario, CA
Serving the Inland Empire from our Ontario office. Hot summers and high AC loads make solar-plus-battery especially valuable here.
What going solar looks like in Ontario
Ontario homes are served by Southern California Edison (SCE), and permits run through City of Ontario. 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.

Local to Ontario
Solar designed around Ontario
We design and install across Ontario — including Ontario Ranch, New Model Colony, Park Place, The Avenue, Creekside, and Downtown Ontario / Euclid Avenue corridor.
Climate & energy use
Ontario sits in an inland valley where summer highs routinely climb into the upper 90s and triple digits, driving heavy daytime and evening air-conditioning loads that often continue well after sunset. Pairing solar with battery storage lets homeowners bank midday production to help cover those hot late-afternoon and evening hours, when SCE's time-of-use rates tend to be highest and grid demand is greatest.
Roofs & housing stock
Ontario's housing stock ranges from older homes near Downtown and the Euclid Avenue corridor, where composition shingle and some Spanish-style clay tile are common, to the large master-planned tract neighborhoods of Ontario Ranch and the New Model Colony, where newer homes often feature concrete tile or composition shingle. We design and flash mounts appropriately for each roof material, since tile and shingle call for different attachment and waterproofing methods.
HOA & design review
Much of newer Ontario, especially the Ontario Ranch villages like Park Place, The Avenue, and Creekside, falls under HOAs with architectural-review requirements, and we prepare and submit the design packages those committees ask for.
