Spain would be the obvious comparison. They're installing rooftop solar like crazy.

  They’ve literally just started so it’ll take a while for them to see the problems. But already: https://www.solarpaces.org/spain-now-needs-csp-for-grid-stability-study/ https://www.solarpaces.org/spain-now-needs-csp-for-grid-stab... https://energypost.eu/spain-as-renewables-rise-managing-supply-and-demand-is-the-next-challenge/ https://energypost.eu/spain-as-renewables-rise-managing-supp... 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: https://www.ecovidahomes.com/blog/can-you-sell-electricity-back-to-the-grid-in-spain https://www.ecovidahomes.com/blog/can-you-sell-electricity-b... 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.
