we had a dude come out and do a quote, and there were more options for placement of panels than we had considered. They can put them on frames to give a better angle to the sun, and the newer ones can work on filtered sun so don't need direct sun all day. We also asked about putting them on the shed, but to do this you also have to factor in cost of wiring etc to get the electricity from shed to your main electricity box. We are on a big block, so the cost outweighed any benefits.

We also discussed benefit to resell value, and a direct financial cost was difficult to determine, but it would definitely be a selling point that might get more buyers to look at the house, which might then drive up the price.

We don't have them on yet but keep revisiting the idea.
