On the one hand, crops under solar panels lets the land do double purpose, at least if the alternative as some sort of shade structure. On the other hand, you've increased the cost of growing the crops, because you need to work around the solar panel structure (which is much beefier than an equivalent shade structure). You've also increased the cost of installing and maintaining the solar panels, because you need to do so at a reasonable height, without damaging the crops, at a relatively low density dictated by the crops. If land is expensive this makes sense, if land is cheap this doesn't... I wonder how often it's actually worth it.
