First Solar is a solar panel manufacturer and installer focused on large, utility-scale solar power plants. They own and control each step of the manufacturing and installation process: panel production, sales, installation, monitoring, and recycling of the solar panels once they’ve met the end of their useful life.
While they don’t work in the residential sector and so their name might not be familiar to you, they’ve left a huge imprint on the solar industry. They’ve installed over 17 gigawatts of solar worldwide – enough to power almost 300,000 average sized homes and in 2016, they were the 6th biggest solar panel manufacturer in the world. However, their products are quite different than the others on that list!
