How Many Peak Sun Hours in California?
California's environment is perfectly suited for high-yield solar production. "Peak sun hours" refer to the specific hours when solar irradiance is strong enough to generate maximum power (1,000 watts per square meter).
Northern vs. Southern California
Southern California (San Diego, Los Angeles, Riverside) boasts some of the best solar conditions in the world, averaging 5.5 to 6.5 peak sun hours per day. Northern California and the Bay Area still maintain an incredibly strong 5 to 5.5 hours.
