portable solar hot air panels
In ref to the question above.. I too would mount them where you can get to them easily.
I mounted the 3 I built on legs.
2 are mounted vertically
1 is mounted horizontally..
1 on my back deck..
2 on the ground but on 2x4 legs about 3 ft off the ground to account for snow build up.
They all work perfectly mounted vertically and even the one I mounted horizontally turns on and off automatically like weeee the people.
19 degree temps?
They all kick on when the sun hits them and produce over 90 degree temps into the house.
Most of the time the temps are in the 100's
no soda cans
just flat plate (aluminum flashing) collectors with ripple clear roofing material for glazing..(plexiglass) purchased from Lowe's
If anyone needs my build info just email me thru this website ok?
