SummaryMost of the largest solar panel manufacturers are based in China, and the country currently supplies 80% of the world’s solar panels, according to the International Energy Agency.China is also winning the solar power race in terms of capacity; it has over three times the capacity of the other top three countries combined, based on the latest numbers from Our World in Data.This could mean that countries and regions such as the UK, the US, and the European Union, who want to increase their use of solar power, might need to take a leaf out of China’s book and start manufacturing more solar panels domestically.If you want more facts and stats about the state of solar power, check out our page on solar panels statistics. FAQs Where is the largest solar farm in the world? The largest solar farm is Golmud Solar Park in China. Situated in the north-western Qinghai province, the solar farm has more than seven million solar panels, which have a combined capacity of 2.8 GW. Who is the biggest solar panel supplier in the UK? Project Solar is the biggest solar panel supplier in the UK, and is also one of the best solar panel installers. It’s been in business since 2011, and has completed over 45,000 solar panel installations nationwide. Are there any solar panel manufacturers in the UK? There are a few solar panel manufacturers in the UK, including GB-Sol, Viridian Solar, and UKSOL. Not all of them manufacture all their solar panel parts in the UK, but all their panels are designed and assembled in the UK.There are also a few companies that make non-traditional types of solar panels. Polysolar, for example, is a UK-based company that manufactures transparent solar panels. AES Solar makes solar thermal panels in the UK.
