Solar & Battery Installation in Mission Viejo, CA
South Orange County homeowners in Mission Viejo trust us for custom solar, battery backup, and the Tesla Solar Roof.
What going solar looks like in Mission Viejo
Mission Viejo homes are served by Southern California Edison (SCE), and permits run through City of Mission Viejo. 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 Mission Viejo
We design and install across Mission Viejo — including Casta del Sol, Aegean Hills, Madrid del Lago, and Deane Homes.
Climate & energy use
Sitting inland in the Saddleback Valley, Mission Viejo sees warm, very dry summers where afternoon highs and hot, gusty Santa Ana wind events push cooling loads well above the milder coastal cities to the west. That combination of strong sun, heavy A/C demand on the hottest days, and SCE's time-of-use rates that peak in the late afternoon and evening makes a solar-plus-battery system especially worthwhile, letting homeowners store midday production to cover the costly evening peak and ride through grid outages during high-wind shutoffs.
Roofs & housing stock
Much of Mission Viejo's housing stock dates to its original master-planned build-out, so Spanish mission-style homes with barrel clay tile roofs are very common alongside concrete tile and composition shingle on later tracts. Tile roofs call for careful flashing and tile-replacement hardware to keep the install watertight, and many homes sit on contoured hillside lots with multiple roof planes and varied orientations, which we account for when laying out panels for the best year-round production.
HOA & design review
Mission Viejo is one of Orange County's most thoroughly master-planned cities with many homes governed by HOAs and architectural review committees, and we handle those design and submittal requirements as part of every project.

Battery backup & solar repair in Mission Viejo
Yes — we handle more than new installs in Mission Viejo. Our in-house crews add battery backup to existing solar systems, diagnose and repair arrays regardless of who installed them, and remove and reinstall panels when a roof needs replacing.
A battery added to an existing Mission Viejo system does double duty: it stores your cheap daytime solar to use in the evening, and keeps essentials powered through outages. And if a re-roof is coming, the tile roofs described in the notes above are why panel removal and reinstallation here is careful, flashing-first work — we detach, store, and reset your system and bring it back online.
