Hi: Boy, that is tough. You could run two down the East slope and two down the West slope facing true South but your roof is about 10 degs to steep, to much shading. You could only use that approach if you mounted all the way at the South end of the house so the shading problem goes away except the whole rest of the roof will then be in the shadows of the thermal units, not good for PV. That would give you 120 tubes which would yield about 100,000 to 120,000 Btu's on a perfect solar day, which would get you part way there. I suppose you could put some PV on the North end facing south but you would have to raise them up a bit for shading issues.. Not an easy install either way....

Hi again,

Interesting. Thanks for that.

I think the situation is not at all good for this house for real RE.

Really time to look for a better place I think... B^>
