Solar & Battery Installation in Altadena, CA
Altadena is an unincorporated foothill community in Los Angeles County, set against the San Gabriel Mountains just north of Pasadena — which means solar permits run through LA County, not a city hall. We've worked on homes throughout Altadena, and as the community rebuilds after the January 2025 Eaton Fire, we're focused on pairing solar with battery backup so homes here are more resilient the next time the winds come down the canyons.

What going solar looks like in Altadena
Altadena homes are served by Southern California Edison (SCE) / Clean Power Alliance, and permits run through Los Angeles County Building & Safety. 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 Altadena
We design and install across Altadena — including Janes Village, Christmas Tree Lane, The Presidents (President Streets), The Meadows, La Viña, and Rubio Highlands.
Climate & energy use
Altadena sits in the San Gabriel foothills above much of the marine layer that dims coastal production — summers are hot, dry, and clear, and orographic lift brings roughly 21 inches of rain a year, more than downtown LA. The same canyons channel severe Santa Ana winds (the conditions behind the January 2025 Eaton Fire), so we engineer arrays for wind exposure and recommend battery backup given SCE wildfire-safety power shutoffs in the foothills.
Roofs & housing stock
Altadena's housing stock spans early-1900s Craftsman bungalows, 1920s–30s Spanish Revival and Tudor-style cottages (including Janes Village), and 1950s–60s ranch tracts like The Meadows — mostly composition shingle, with clay tile on Spanish Revival homes. Older roofs often warrant a roof-condition and structural check before mounting, while post–Eaton Fire rebuilds mean brand-new roofs where solar is easiest to integrate from day one.
HOA & design review
Most of Altadena has no HOA — its historic neighborhoods predate the master-planned era, so the majority of homeowners face no architectural-review step. The main exception is the gated La Viña community, which has a homeowners association; under California solar-rights law, an HOA can review aesthetics but cannot prohibit a properly permitted solar installation.
