Anyway, how does it stack up, availability-wise, against grid-power power sources? My brother-in-law has a PV system and about the best he ever does is 50% for the PV output at the bus bar. Usually more like 25-30%, but that's in the Denver area. I told him he needs to move his house to the Mojave to get a decent output from the PV, but for some reason, he won't listen to me.
