Photovoltaic solar energy is the fastest-growing energy source in the world. CurrentlyChina, India, and the US produce the majority of the global solar power, with the Middle Eastcoming on strong. Growth is booming — especially in the deserts of Asia and the Middle East, where huge solar farms are in the process of being built and expanded. To give you a taste of just how rapidly the adoption of solar power is expanding, we’ve profiled five of the largest solar plants currently in operation. Enjoy!

Tengger Desert Solar Park

Largest solar farm in the world

Location: ChinaSite Area: 43 square kilometersOutput: 1,547 MW

Known as the “Great Wall” of solar power, the Tengger Desert Solar Park is the largest solar farm currently in existence. Located in China’s Tengger Desert, the solar field occupies only 3.25 percent of the arid land in the region.  That might not sound that big, but it’s actually more than 10 times larger than New York’s Central Park, and is capable of producing 1.5 Gigawatts of power, rivaling the power capacity of mostnuclear power plants. With plenty of room to expand, we expect Tengger to be a top solar power producer for years to come.

Bhadla Solar Park

Largest solar farm in India

Location: IndiaSite Area: 40 square kilometersOutput: 1,365 MW

The Bhadla Solar Park currently produces 1,365 MW, but that is about to change. The facilityis expanding rapidly, and has plans to produce an additional 880 megawatts by March of 2019. Once it reaches full capacity next year, Bhadla will claim the title as the largest solar facility in the world and will help India come closer to its goal of obtaining 17% of its energy from solar power.

Longyangxia Dam Solar Park

Renewable hybrid power with solar and hydroelectric

Location: Tibetan Plateau, ChinaSite Area: 27 square kilometersOutput: 850 MW

Longyangxia Dam Solar Parkwas completedin 2015 and is integrated with the facility’s 1,280MW Longyangxia hydroelectric dam. Together the two power sources complement each other. Solar power helps to conserve water usage by the dam, while the hydroelectric dam balances out the variable energy production from solar cells.

Villanueva Solar

Largest in North and South America

Location: Coahuila, MexicoSite Area: 24 square kilometersOutput: 828 MW

The Villanueva solar power facilityhas been growing steadilywith the commissioning of the 427 MW Villanueva 1 park and the 327 MW Villanueva 3 park in early 2018. Enel Green Power Mexico, which oversees the plants, continues to add capacity in small chunks, with a goal of reaching 1,700 GWh per year once the facility is fully operational. This facility is part of Mexico’s commitmentto supply 35 percentof its electricity from clean sources by 2024.

Kamuthi Solar Power Station

Largest solar farm in the state of Tamil Nadu

Location: Tamil Nadu, IndiaSite Area: 10 square kilometersOutput: 648 MW

As of the writing of this post, the Kamuthi Solar Power Station is the sixth largest solar farm in the world. Built in a mere eight months, the plant went online in September 2016. The 2.5 million solar panels at the facility produce enough power for 750,000 people. One cool fact: the facility is cleaned daily by a fleet of robots who are charged by the solar panels they service.

Solar Star Solar Farm

Largest solar farm in the US

Location: Rosamond, CaliforniaSite Area: 13 square kilometers (5.0 sq mi)Output: 580 MW

One of the older plants on our list, construction began on the Solar Star power plant in 2013 and was completed in 2015. The facility includes1.7 million solar panelsthat can supply electricity to power the equivalent of approximately 255,000 homes. Solar Star hails from California, which leads the US with almost 23GW in solar energy and accounts for nearly 17 percent of California’s electricity supply.

Mohammed bin Rashid Al Maktoum Solar Park

Largest planned solar farm under construction

Location: UAESite Area: 77 square kilometersOutput: 5,000 gigawatts planned by 2030

The 213MW Mohammed bin Rashid Al Maktoum Solar Park may pale in comparison to other facilities, but it hasbig plansfor the future. The solar parkhas planned improvementsthat are expected to generate 1,000 MW by 2020 and an incredible 5,000 MW by 2030. Not only will it be the largest solar park in the world, but it also will have the world’s tallest solar energy tower. The 260-meter tower is part of phase four of development and will contribute 700MW to the plant’s total output.
