In California, which receives more than 3000 hours of light a year, solar power installation is at a very high level. It is an ideal place to install photovoltaic solar panels and solar heating systems. This includes local distributed generation and grid-scale solar power plants. Thanks to the Renewable Portfolio Standard, 1/3 of the state electricity needs come from renewable sources until 2020. Most of this energy requirement comes from concentrated solar power plants and PV facilities.
Besides, the decision of the California Energy Commission unanimously, requiring solar energy panels in all detached houses and apartments to be built after January 1, 2020, has also provided important developments for the State.
In California, the Solar Energy Industries Association (SEIA) reported that it has 27,400 MW of solar installed capacity, which makes up 20 percent of the total electricity produced in the state, according to the open 2019 statements. Thus, California has the capacity to generate enough solar energy capacity to power around 8 million homes as the leading solar generating state in the country. In the next five years, the state is expected to add another 16,000 MW of solar capacity to its current capacity.
California has dozens of different solar energy systems contractors. These companies provide solar energy systems installation services to many individuals or corporate companies locally and nationally. After these companies start the projects they offer, they become the executors of all transactions from A to Z. Also, they follow the possible discounts and supports they can get from the government.
In addition to this, the Solar Star project with an installed power of 579 MW, which was implemented in California in 2015, was the largest solar energy factory in the American continent at first, and it has already managed to stay in the top 10 in the list of giant solar companies with other companies established later.
