California is a leader in the solar industry, with more than 1.5 million solar panel systems installed statewide as of September 2022. Solar panels may be a good option if you live in the Golden State and are interested in lowering your household carbon emissions while also saving on energy bills.
California’s average residential electricity rate is higher than the national average. According to CNET’s corporate partner, SaveOnEnergy, Californians often pay a higher traditional energy bill than residents in other states.
You can find your 12-month energy consumption on your electric bill to calculate the possible savings you’d get from solar. According to the Energy Information Administration, California’s average residential electric bill was about $131 per month in 2021, or $1,568 over a full year. That means if you invest in a solar system that covers your entire energy usage, you could save up to $1,568 each year with solar energy. It’s also worth noting that in June 2022, electricity rates in California had increased 25% from June 2021, so your could increase.

Whether you’re interested in helping the environment or lowering your energy bills, the amount you could save on solar panels in 2022 is higher than in previous years.
California solar panel costs
The cost of a home solar panel system will depend on the system size (i.e., the number of panels included), components like solar batteries and installation costs. California’s average solar panel system is smaller (and therefore cheaper) than the national average, even though the cost per watt is normally above the US average.

The age and overall condition of your roof are also considerations. Older roofs or roofs needing maintenance should be replaced or repaired before solar panel installation. can affect how much electricity a solar system generates. According to the

But they’ll be much more efficient when installed where they receive at least four hours of direct sunlight each day. If your home is in a cloudy region of California or gets shade coverage throughout the day, a solar panel system will not generate as much electricity as it would with direct sunlight.
- HOA and neighborhood regulations: California law prohibits HOAs from banning solar panel installations, but there may still be specific requirements and approval processes in your neighborhood.

California solar power FAQs
Is solar power good for the environment?
Solar power has pros and cons, but generally, it is a more sustainable power source than coal or gas. Fossil fuel electricity sources emit greenhouse gases, including carbon dioxide, into the air when burned. Burning fossil fuels for energy is the main driver of climate change and contributes significantly to air pollution. Scientists say we must rapidly transition away from fossil fuels to avoid the worst effects of climate change. Solar energy is a greener alternative to fossil fuels because it is renewable (the sun will always produce the energy needed to create electricity), and converting the sun’s power into electricity for a home does not produce greenhouse gases. While the manufacturing of solar panels has some impact on the environment, it is much lower over the panels’ lifetime when compared to the carbon emissions from fossil fuels.
Does California require home solar panels?
In 2018, California passed a mandate requiring new single-family homes and multifamily buildings up to three stories high to install solar panels. This mandate took effect in 2020 and requires new construction projects to include a solar system large enough to cover all of the household’s energy needs each year based on the climate and square footage of the home. If the system includes a solar battery, the builder can reduce the system size by up to 25%. If you live in a home built before 2020, you are not required to purchase solar panels.
