Cost of raw #solar cells is unbelievably stupid: ~40$ per 1000W delivered to loading port. Peak electricity price here is something like $0.12/kW•h. So even with 50% overall efficiency it breaks even after ~800 hours of runtime. That’s fucking 100 somewhat sunny days at worst. One again: after 100 (one hundred) sunny DAYS you will have absolutely free electricity basically for the rest of your life. The rest of the panel price are shipping, labor, aluminum, glue, glass, copper, couple diodes and some solder. But wait! Factories producing don’t have enough buyers and work at half of capacity. One again: raw solar is dirt cheap and no one is fucking buying them! Oh, and at the same time China is adding something like 400 gigawatts of solar capacity per year. Global annual electricity demand is up to ~30000 TW•h or something like 82TW•h per day. 60% of that is fossil fuel Say cell can generate 1W in a whole day. To cover fossil fuels production use we need 50TW of solar which is roughly $2T worth of raw cells. Big number, but global GDP is $118T. So that’s just 2.3%. But here is a thing: estimated global fossil fuels subsidies anywhere from $0.9T to $6.7T in 2024, depending on how you count. Yeah, those numbers are based on sport raw cell prices. But wafers end cells are fucking HIGH TECH part of them and like half of cost. The rest is sweat, glue and glass. Anyone who can hold a soldering iron can assemble modules in panels. Solar transition is limited not by production but by fossil fuel bribery of the politicians, who impose taxes, tariffs and other completely made-up expenses to slow solar down. If we wanted we would’ve already replaced most of fossil with solar. Fuck politicians. Fuck governments. Fuck fossil fuels and their “stakeholders”
