The cost of new Photovoltaic power panels has fallen dramatically in the last decade. Utility-scale solar is 7 times cheaper (per generated kWh) in 2020 compared to 2010. The world's total solar capacity been growing at an exponential rate of 20-30% each year, and added 126 gigawatts of capacity in 2020 alone.
How much new solar PV capacity will be installed globally in 2030?
This question will resolve as the global new solar capacity installed in 2030, in gigawatts. For example, according to Our World In Data, 126.7 GW of capacity was installed in 2020. Resolution may come from the BP Statistical Review of Energy, official government estimates, or other independent energy researchers such as IRENA
