I know a solar farm developer that was originally going to go with Thin Film for his installation, but to get the power capacity he would have wanted, he would have had to literally cover almost the whole farm land. The ground was naturally contaminated with sulphur as it happened, so it wasn’t usable farm land, but I know allot of people who spend time thinking about land use (Bureau of Land Management in the US, Ministry of Agriculture here in Canada for example) who worry about this possibility. That’s one of the reason I love tracking systems – you get up to 44% more power per day, and you can dual use the land. These pics from an orange orchard in Spain are the prettiest examples I’ve seen – they used to use diesel generators to power the water pumps. (These are not ours, but we’re looking at that brand of tracker.)
Pretty, eh? Here’s another.
