Compass orientation as well. Any chance of a wind turbine? https://windempowerment.org/the-piggott-turbine/ Ok, here you go. Dont know roof angle exactly, but very shallow. Typical modernish ag building. I think the wind turbine would be pushing it. Way to visible. Someone will complain. Some will complain about anything. Ground based solar is potentiall possible. Maybe. Link to comment Share on other sites More sharing options...

So October to April at most. No requirement outside of that. 1 Link to comment Share on other sites More sharing options...
SteamyTea Posted February 1, 2022 Share Posted February 1, 2022 (edited) So you got about 100m2 of almost south facing roof. When you get some time, find a sheet of something, insulation would be best. Get up in the eves and fit it 200mm below the inner roof. Seal all the edges, cut a hole at the top and the bottom for a small bathroom fan, wait till it is sunny, pump some air though and see what happens temperature wise. If you can capture 50W.m-2, that is 5 kW. Going to be up your way, again, again, come the weekend. Edited February 1, 2022 by SteamyTea Link to comment Share on other sites More sharing options...

Going to be up your way come the weekend. Yes, its quite large. But those trees are tall. So in winter the roof loses the sun quite early. Nice idea. Will need to try that. Wonder what that will produce?. Are you popping in for a cup of steamy tea? 2 Link to comment Share on other sites More sharing options...

If he has "metal" walls could he paint them black and run pex-al-pex across. Then polycarb sheet over the front. Insulate inside. Link to comment Share on other sites More sharing options...
