The state of solar power in San Diego, CA

California is among the largest producers of solar power in the U.S., with San Diego being one of its major contributors. As of 2016, the city ranked second for solar power capacity. By 2018, the Solar Energy Industries Association ranked the entire state of California first in the nation for solar generation.

Bright sunny days with clear skies are hallmarks of San Diego and make it perfect for solar power. Various laws and government incentives have also helped create a major shift toward renewable energy.


How much solar power does San Diego, CA produce?

San Diego generates far more electricity than most cities in the U.S. In fact, California produced so much solar power in 2017 that it had to pay neighboring states like Arizona to take some of that electricity to avoid overloading its power grid.

Currently, California generates 26,232.25MW of solar-powered electricity from 1,055,286 installations. That’s enough electricity for 6,828,939 homes—and more homes powered by solar than anywhere else in the U.S. Solar power generation in California is expected to rise another 15,867 MW over the next five years.

San Diego itself, per the California Energy Commission, has a 147.6 MW solar power production capacity and 354,024 net MWh.

Is solar power generation feasible in San Diego, CA?

Thanks to its climate and land area, solar is more than just feasible in San Diego - it's ideal. The city’s Direct Normal Irradiance (DNI) stands around 5.88, meaning it has excellent weather, maximum sunlight, and minimal airborne particulates.

In addition, California legislation and various incentives make installing solar systems a pocket-friendly long-term investment. Homeowners can choose to get their solar power from power companies or generate their own via residential systems.

Two system types are popular in the sunshine state—solar thermal and solar photovoltaic (PV). Solar thermal systems generate electricity by using sunlight to warm fluids and make steam. The steam generation turns turbines, which generate electricity.

On the other hand, solar photovoltaic (PV) directly converts the rays from sunlight caught by solar panels into electricity. Solar PV electricity generation exceeded that of solar thermal in 2008 and is now the most common solar system type in California.

How much does solar power cost in San Diego, CA?

Compared to other states, solar installation is quite affordable in California, including in San Diego. The cost of solar in the state has dropped by 36 percent over the last five years. The average payback period for solar in San Diego is 4 years, 6 months, but this will vary depending on the system type and size, cost of electricity, and availability of net metering.

How can I start using solar in San Diego, CA?

Considering the ease, energy-efficiency, and cost benefits of switching to solar power in San Diego, its no wonder California is leading the way in the solar power revolution.
