The state of solar power in San Francisco, CA

A solar PV system allows you to use a free and abundant energy source - the sun's light - and convert it into electricity that you can use to power appliances in your home. If you live in San Francisco, CA, you are in one of the best places in the U.S. for solar power.

California has well above average peak sun hours per day. According to the Solar Energy Industries Association, it also ranks first in the US when it comes to renewable energy investments and incentives to promote the installation of solar PV systems.


How much solar power does San Francisco, CA produce?

Despite being a relatively small and foggy city, San Francisco’s solar power production is significantly higher than that of most other cities in the United States.

In 2016, the city mandated that all new buildings that are less than ten stories have solar panels that cover at least 15 percent of the roof. At that time, the city had 24.8 MW of solar capacity. Today, the municipality alone has 23 installations pumping out 8.6 MW to power libraries, high schools, and even city hall.

Is solar power genergation feasible in San Francisco, CA?

Solar power generation is highly feasible in San Francisco. The city gets an average of 259 sunny days per year, which is significantly higher than the national yearly average of 205. During those sunny days, San Francisco has approximately six peak hours of light in the summer and 3.5 peak hours in winter, during which solar panels produce electricity at optimal capacity.

Another factor that contributes to San Francisco’s solar feasibility is its Global Horizontal Irradiance of 4.35 kilowatt-hours per square meter per day, which is 7 percent higher than the average. The climatic and environmental conditions in San Francisco allow for high solar energy potential and relatively short solar cost offset times.
