Solar & Battery Installation in Downey, CA
Downey sits in the heart of southeast Los Angeles County, where a classic mid-century housing stock meets one of the region's more streamlined solar processes. The city permits rooftop solar through its own Building & Safety Division — including automated SolarAPP+ review for standard residential rooftop systems — and power is delivered over Southern California Edison lines with Clean Power Alliance as the community's default generation provider.
What going solar looks like in Downey
Downey homes are served by Southern California Edison (SCE) / Clean Power Alliance, and permits run through City of Downey Building & Safety Division. 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 Downey
We design and install across Downey — including Orange Estates, The Island, Northeast Downey, Northwest Downey, Downtown Downey, South Downey, and Rio San Gabriel.
Climate & energy use
Downey sits about a dozen miles inland on the flat floor of the Los Angeles Basin, so spring and early-summer marine layer ("May Gray" and "June Gloom") can shade mornings before burning off, while summers run warmer than the coast but noticeably milder than the inland valleys — August is the warmest month. The flat, fully urbanized terrain carries essentially no wildfire or PSPS exposure, so production here is steady and predictable year-round.
Roofs & housing stock
Downey's housing is quintessential postwar Los Angeles: the median home dates to 1959, built out during the city's 1940s–1960s boom, and the streets are dominated by single-story ranch and traditional houses with composition-shingle roofs, plus scattered Spanish-style homes with clay tile and some newer infill. On roofs of this vintage we verify roof condition and remaining shingle life before mounting, and older electrical services are evaluated for panel capacity during design.
HOA & design review
Most of Downey's mid-century single-family neighborhoods have no HOA, so architectural review is rarely part of the process here; associations are generally limited to condominium and townhome communities. Where one does apply, California's Solar Rights Act (Civil Code Section 714) prevents unreasonable restrictions, and we prepare any required application materials.
