Southern California has 300+ sunny days a year and some of the highest electricity rates in the U.S. Going solar now means:

  • ☀️ Maximum sunlight → more free electricity from your roof
  • 💡 Shielding from utility rate hikes (SCE, LADWP, SDG&E, Edison)
  • 🌎 Support for California’s clean energy future
  • 🏡 Higher home resale value (buyers love solar-equipped homes)
  • 🔋 Energy independence — especially if paired with battery storage

 

2️⃣ Residential vs. Commercial Solar Installation

Feature Residential Solar Commercial Solar
