> This is a common rebuttal, but not grounded in reality. Even assuming ~20% capacity factor for "apples to apples" comparison to legacy thermal and nuclear, solar and batteries are the cheapest form of power to install.
I looked it up because I was curious, according to Wikipedia average PV capacity factor is 25 % in USA, 10 % in the UK or Germany.
Nuclear has 88 % capacity factor worldwide. Meaning to replace 1 GW of nuclear installed capacity you need 8.8 GW of PV installed capacity in Germany or 3.5 GW of PV installed capacity in US.
Which might still be economically worth it, I don't know. But it is a number that surprised it.
