Largest Solar Farms in the USA – Top 7 List Details 🌞

Solar panels are being used extensively in the world to generate electricity. In which the USA is embracing such renewable energy sources.

This is because the USA is trying to generate large amounts of electricity by building solar farms using solar energy to reduce fossil fuel consumption and reduce carbon footprint.

The world’s largest economy has built some of the world’s largest, most beautiful, and high-yielding solar farms. The following are the 7 most giant solar farms in the United States.

1. Solar Star, Kern & Los Angeles Counties, California

Solar Star is the largest solar farm in the USA that was completed and operated in June 2015. Until 2017, the Solar Star project was the world’s largest solar field in the US.

This is a kind of power project with a photovoltaic solar power facility.

Solar Star Farm Location and Site Details

Solar Star Farm is in Kern and Los Angeles Counties, Antelope Valley, in southern California. It is spread over 13 square kilometers and contains 1.7 million solar panels.

This place has been chosen due to the high quality of solar resources and very low rainfall.

It is approximately as big as 142 football fields, four times larger than Central Park.

Capacity Of Solar Star Project

The Solar Star Plant has been set up in two sections: Solar Star 1 and Solar Star 2.

Solar Star 1 has a capacity of 314 MW, and Solar Star 2 has a capacity of 265 MW. In total, both generate a total of 579 MW of solar energy. That’s enough electricity to power about 255,000 homes.

So, It ranks first among the largest solar farms in the USA.

According to NS Energy, The Star project uses approximately 1.72 million PV solar models mounted on a single-axis track to follow the sun’s movement for solar power generation.

Solar Star completed its fifth year in June 2020 and is still the largest solar farm in the country in terms of electricity generated by the Solar Star project.

  1. Informative article however, one has to remember that Solar (and wind) can only produce power 10 – 30% of the time. I have seen many comparisons between coal, natural gas, hydro, nuclear and solar. When making the comparison between Solar/Wind and the rest, one has to account for the 70-90% inefficiency of Solar/Wind. Meaning, they are not one-to-one when stacked against coal, natural gas, nuclear etc..
