Solar installation in Altadena, CA
Custom-designed solar and battery systems for Altadena homeowners. Southern California Edison expertise, no high-pressure sales — just a transparent quote.
Solar installation in Altadena means something different since January 2025. For families rebuilding after the Eaton Fire, solar usually isn't optional: homes rebuilt to today's Title 24 energy code generally must include a solar system, and the right time to design it is with the architect — not bolted on after drywall. Done during construction, it's also cheaper and cleaner: conduit inside the walls, panel placement integrated with the roof plan, battery and main panel sized once. For the Altadena homes that still stand, the calculus is the foothill classic — SCE NEM 3.0 battery math plus real PSPS exposure against the San Gabriels. Permits run through LA County Building & Safety, including the county's rebuild pathways, and we handle that process end to end. This is a community we work in with care; every design gets Taylor's personal review, and every quote is line-itemed.
What solar looks like in Altadena.
Every market has different utility rules, sun resources, and structural realities. Here's what we factor in when designing for Altadena homes.
Rebuilding after the Eaton Fire generally means meeting today's Title 24 energy code — which requires solar on most new homes. We help families fold that into the rebuild the right way, not as an afterthought

Why Altadena homeowners choose Helios.
We design and install across Altadena — from the Meadows, Janes Village, and President Streets, near Christmas Tree Lane, Eaton Canyon, and the Cobb Estate gates. Historically 1920s–40s craftsman and Spanish homes under the San Gabriels; after the 2025 Eaton Fire, much of Altadena is now active rebuild territory — new construction built to current energy code.

Altadena's utility: Southern California Edison
How net metering works for you.
SCE operates under NEM 3.0 (effective April 2023), which cut export rates ~75%. A solar+battery system is essential for healthy ROI here.
Production estimate
A typical 8 kW system on a Altadena roof produces approximately 16,352 kWh per year given 5.6 peak sun hours per day. We'll model your exact roof, shade, and azimuth in your free assessment.
Inland-valley summers are long and hot, which means strong solar production and the kind of high A/C bills that solar offsets especially well.
* Ballpark estimate. Actual production depends on roof pitch, orientation, shading, and panel choice.

Altadena solar questions, answered.
- Does a rebuilt Altadena home have to include solar?
- Generally yes — homes rebuilt to current California Title 24 code must include a solar PV system, with limited exceptions (shading, small roofs). It's sized to the home's expected usage, and adding battery storage during construction is far cheaper than retrofitting. We coordinate directly with your architect or builder so it's designed in, not tacked on.
- How much does solar cost in Altadena?
- For new construction during a rebuild, solar typically prices better than retrofit — roughly $2.20–$3.00 per watt folded into construction, with the battery and panel sizing done once. For existing homes, standard retrofit pricing applies (roughly $2.40–$3.25/W, $17,000–$30,000 typical). Every quote is line-itemed either way.
- Does Altadena get PSPS shutoffs?
- Yes — the foothill zone along the San Gabriels carries real Public Safety Power Shutoff exposure during wind events, which the community knows all too well. A battery keeps critical loads running through shutoffs and earns daily under NEM 3.0 by covering the 4–9 PM peak from stored solar.
