There are actually a lot of people who think it increases overall efficiency for some farms - mainly in areas with more sun / hotter temps / less water. If you have a less dense amount of photovoltaics then you still get quite a bit of sun and they end up reducing the amount of water evaporated by quite a bit which is very important for growing crops in areas like California. We could end up with much higher overall land use efficiency.
