Solar Star, California’s most extensive and best-producing solar farm, provides enough clean energy to power 250,000 homes. The farm stands in Kern and Los Angeles counties and is not only the most significant Solar Farm in California but the largest in the world when completed in 2015. The Solar Farm comprises 1.7 million solar panels spread over 13 square kilometers (3,200 acres). That’s 142 football fields or 4 Central Parks!

Solar Farm

Solar farms are large plots of land with photovoltaic, or PV, solar panels.

Solar Star

California is the leading state in renewable energy and hosts some of the largest solar power plants in the United States. Solar Star produced 579 megawatts of energy, enough to power 255,000 homes. Southern California Edison buys that energy and distributes it to its customers. The farm splits into two installations: Solar Star 1 and Solar Star 2. Solar Star 1 produces 314 MW, and number 2 makes a little less at 265 MW. Solar Star ranks as the largest installed capacity, using 1.7 million solar panels over 13 square kilometers. 

Compared to other solar plants, Solar Star is smaller in terms of size. This is because Solar Star uses a smaller number of crystalline silicon modules. Still, the modules they use are higher wattage, higher efficiency, and higher cost with newer technologies that follow the sun’s rotation throughout the day. In addition, the panels at Solar Star clean themselves automatically in a way that uses minimal water than other panels at other farms. These same solar panels also follow a new technology that uses a single-axis tracker to track the sun’s movements across the sky. This new technology makes the panels 25% more efficient than panels that don’t move.

There are over 2,500 solar farms in the United States.

The designers built Solar Star near Rosamond, California, on “disturbed” land, meaning people have altered or made the land. SunPower Services operates and maintains the farm. The power plant created 650 jobs over three years, and Cleantechnica reported that Solar Star created 40 maintenance jobs and 15 full-time site position jobs over its lifetime. It is hard to put the environmental impact of a project this size into perspective but to try. Solar Star is the ecological equivalent of taking 108,000 cars off the road yearly. 

How is Solar Star the Largest Solar Farm in America?

Even though completed in 2015, Solar Star still reigns as the highest-producing solar farm in the United States in terms of power generated. Solar farms in California, like Desert Sunlight and Topaz power plants, produce 550MW each. These solar farms take up more space (3,800 and 4,700 acres compared to Solar Stars’ 3,200), but Solar Star still comes out on top in terms of efficiency per area, based on location and engineering. 

What Animals live around Solar Star?

California’s largest solar farm, Solar Star, is located in Rosamond, California, in the Antelope Valley region of Southern California. While the area is predominantly desert and agricultural, several wild animal species can be found in and around Rosamond. In addition, some notable wild animals may inhabit or pass through the area.

Other Solar Farms in California 

Desert Sunlight Farm

The Desert Sunlight Farm is a 550-megawatt photovoltaic power station. It sits approximately six miles north of the rural community of Desert Center in eastern Riverside County, California, in the hot Mojave Desert. The Desert Sunlight photovoltaic solar farm produces 550MW of power capacity. The project was conceptualized by First Solar in 2008, approved in August 2011, and construction started in September 2011 and was finally completed in February 2015. The farm was built on 4,100 acres of land that the US Bureau of Land Management manages.

 Desert sunlight has approximately eight million FirstSolar Series 3 Cadmium Telluride (CdTe) thin-film PV modules. The project utilized 70,000t of American steel and generated 550 construction jobs. The PV modules installed at Desert Sunlight don’t require water for electricity generation or cleaning and generate no air, emissions, or waste. 

Desert Sunlight can generate 1,060GWh of electricity a year, which can serve 160,000 homes in California and equates to offsetting 300,000t of carbon dioxide emissions a year compared to the use of fossil fuels. The project supported the state’s target to generate 33% of power from renewable resources by 220. In addition to creating 550 construction jobs, it produced 15 permanent jobs and a gross indirect local economic benefit of $336m for Riverside County. 

Under two separate power purchase agreements (PPA), 300 MW of renewable energy from Desert sunlight is delivered to Pacific Gas & Electric (PG&E), while the remaining 250MW is provided to California Edison (SCE). The PPAS is valid for 25 years and 20 years, respectively. 

Topaz Solar Farm

Topaz Solar Farm is a 550-megawatt photovoltaic power station in San Luis Obispo County, California. Construction on the project began in November 2011 and finished in November 2014. Topaz ranks as one of the world’s largest solar farms but still is not bigger than Solar Star. It has 550MW of power Capacity, and at its total operational capacity, the plant produces enough electricity to power more than 181,000 homes. According to BHE Renewables’ estimates, this is sufficient to remove about 407,000 metric tons of carbon dioxide annually and is equivalent to removing 77,000 cars from the road. 

Topaz invested around $2.5bn and created 400 jobs during construction. Covering an area of approximately 4,700 acres, the Topaz Solar Farm stands in unincorporated easter San Luis Obispo County, California, near the small community of California Valley. 

Each solar photovoltaic module has a dimension of 4ft by 2ft and weighs 27.5 pounds. These modules mount together on panels supported by steel columns with advanced thin-film attributes capable of generating electricity without emissions, waste, or water use.
