Local Installers,
Not Out-of-State Sales.
Valley Sun Solar is a local, family-owned installer based right here in Simi Valley. Our crews — not subcontractors — do every install. We carry our own C-46 Solar contractor license (CSLB #1058294), and we back our workmanship for 25 years. No door-knockers, no high-pressure sales, no white-label crews you've never met.
“Solar only works if the system is designed right for your roof and your bills. We'll tell you honestly if it's not a fit — and we walk away from jobs that wouldn't pay back.”

“Got quotes from four solar companies. Valley Sun was the only one who actually walked the roof, pulled our last 12 months of bills, and showed us three sizing options with real numbers. No upsell on battery until we asked. Production is matching their design almost exactly seven months in.”

“Moved into a home that already had solar but the system was performing terribly. Priya's team diagnosed two failed microinverters and a loose combiner box connection — fixed in one visit. Production doubled. Wish we'd called them first.”

“Added a Powerwall 3 to our existing solar after last summer's blackouts. Clean install, perfect cable management, and the PTO paperwork with SCE was handled start to finish. Worth every penny.”
