Actually returns (on solar companies) will probably be pretty high. See https://en.wikipedia.org/wiki/Swanson%27s_law https://en.wikipedia.org/wiki/Swanson%27s_law and https://en.wikipedia.org/wiki/Growth_of_photovoltaics https://en.wikipedia.org/wiki/Growth_of_photovoltaics Looking at the graph from the first link, what will likely happen is solar installations will grow rapidly to meet the trend line, which means high revenue growth. Solar is also currently priced like it's dying, so there'd also be a price/earnings increase.
