USA is an unquestioned champion in the solar industry. Many of the world’s biggest and most productive photovoltaic stations and farms are located in the United States. The nation boasts dozens of solar PV plants whose capacity exceeds 200 megawatts. All of them have been deployed within the last decade. 
Over a half of the top nation’s utility-scale PV projects are based in California – the sunniest state of the country. The Beach State houses the largest solar power station as of 2020 – 579MWAC Solar Star. 
Nevada ranks second, accommodating the second-largest and a few more over-200-MW plants. 
The PV systems in the list rank according to their capacity. Keep it in mind that the sector is growing rapidly and the rating is changing. But you can rest assured that we are doing our best to update the info regularly to keep you in line with the fresh news.
