What Affects Solar Cost in Pasadena?
Key factors that determine your Pasadena solar installation price
System Size
Most Pasadena homes need 6-10 kW systems. Craftsman-style homes in neighborhoods like Bungalow Heaven typically need 6-8 kW, while larger homes in San Marino-adjacent areas may require 10+ kW.
Roof Type
Pasadena's historic Craftsman and Spanish Colonial homes often have complex roof lines. Installation costs vary based on roof material, pitch, and accessibility.
PWP Net Metering
Pasadena Water and Power, a municipal utility, offers its own net metering and solar rebate programs independent of California's investor-owned utilities.
Historic District Rules
Homes in Pasadena's historic districts may have additional design review requirements for solar installations. Most approve low-profile panels that match the roofline.
