We’ve already carried out this experiment. Rooftop solar is a luxury good that doesn’t actually reduce fossil fuel dependence.
Thankfully Spain has learned the lesson of California & is only giving a wholesale rebate on the bill meaning you’ll never make money from rooftop solar:
But that doesn’t change the math that using public funds to incentivize rooftop solar is a populist direction that isn’t actually a good idea for the grid. Once enough rooftop solar is installed, watch the grid in Spain start to struggle financially if they haven’t priced the T&D hookup fee correctly (+ expect that fee to rise over time). All that being said, Spain & Europe are slightly different stories - they have a unified electricity grid I believe which lets them export their surplus. Not sure if that actually works for rooftop solar but may help mediate some of the problems that we have in the US.
