The land doesn't have to be purchased though, there are plenty of uses which cooperatively use the land. Parking lots, and solar-agriculture. The coop use may even improve the hybrid performance - a little less sun and a little better shade microclimate for humidity can even be a crop yield booster (esp with climate change induced droughts).
- dublin 4y agoJust putting arrays on commercial rooftops is the most cost-effective solution by far. And no you can't really grow crops or much of anything but low grass/weeds under the panels due to 1) the problems (of shading with tall weeds or crops), and 2) the potential for damaging the surprisingly fragile wiring. (And don't get me started on this, but most arrays are wired stupidly, ignoring what the telegraph and phone guys learned 125 years ago: you want to ground the positive leg, NOT the negative, so you can use cathodic protection via a sacrificial anode to prevent the wires corroding away. You would be shocked how many 10-15 year old arrays I've seen that have something rapidly approaching empty straws of insulation connecting the panels - the breakeven on a solar PV plant is around 20-22 years, so these will never break even!)
