Solar Industry Statistics

Solar is already reshaping power and supply chains, from U.S. residential installations making up just 0.3% of generation to solar PV expected to grow 2.3 times by 2030 in the IEA’s stated policies scenario. You will also see how policy incentives like the 30% ITC through 2032 and storage co development have shifted new capacity patterns, alongside the climate impact of 2.3 million metric tons of CO2e emissions avoided by solar thermal and PV generation.

Global solar PV demand has surged to roughly 450 GW in 2023, but the more surprising story is how quickly the industry is turning that demand into capacity while costs and constraints keep shifting. From the U.S. where solar helped displace 2.3 million metric tons of CO2e, to Europe pushing toward 40 GW per year of solar manufacturing, the sector is changing on multiple fronts at once. This post pulls together the most telling solar industry statistics so you can see where growth is accelerating and where the bottlenecks are easing.
