Solar & Battery Installation in Costa Mesa, CA
We install solar and battery across Costa Mesa — from Mesa Verde to the Eastside — on Southern California Edison, with permits run through the City of Costa Mesa, backed by our nearby Irvine crews for some of the fastest turnarounds in Orange County.
What going solar looks like in Costa Mesa
Costa Mesa homes are served by Southern California Edison (SCE), and permits run through City of Costa Mesa. 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 Costa Mesa
We design and install across Costa Mesa — including Mesa Verde, Eastside Costa Mesa, Mesa del Mar, Halecrest, and College Park.
Climate & energy use
Costa Mesa sits just a few miles inland from the coast, so summer mornings often start under a marine layer (the local "May Gray" and "June Gloom") before clearing to warm, sunny afternoons that drive most of the cooling load. Pairing solar with a battery here helps shift that midday and late-afternoon production into the evening and through the dry, warm Santa Ana wind events that can stress the grid in fall.
Roofs & housing stock
Costa Mesa's housing stock leans heavily on 1950s-70s mid-century ranch homes with low- to medium-slope composition-shingle roofs, alongside Spanish-influenced clay and concrete tile in newer and remodeled pockets. Single-story ranch rooflines often offer large, unobstructed south- and west-facing planes that lay out well for panels, while tile roofs call for tile-specific flashing and careful hook placement to keep the roof watertight.
HOA & design review
Several Costa Mesa tracts and condominium communities have HOAs with architectural-review requirements, and we handle those approval submittals alongside the city permit.

Battery backup & solar repair in Costa Mesa
Yes — we handle more than new installs in Costa Mesa. 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 Costa Mesa 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.
