Ok, the weather finally cooled off and allowed me to finish the panel. I coated the whole thing in 4 coats of KILZ white sealer. I did not use pegboard for the cell mounting substrate because I didn’t like the holes. I instead used 1/8″ door skin which worked out excellent. I also did not glue the cells down with blobs of silicone. I decided to use 1″ Scotch heavy duty mounting squares which are adhesive on both sides. You just peel the tape off of the outside and stick them down. I am not sure how these will work VS. silicone in the long run, but I experimented with a cell by sticking it onto a scrap piece of door skin and the bond was permanent. I had to destroy the cell to get it off of the scrap piece. So, hopefully they will work. All that is left to do now is get a piece of glass cut, silicone that down and put some aluminum channel on the outside. This entire thing is going to cost around $140 to build. The panel puts out 63 watts, 19.25 volts and 3.63 amps. Not bad.
Together with our partner Giertsen Bredenoord installed an an off-grid solar-based power plant at the Medina hospital in Somalia. The installation makes optimal use of solar energy in combination with an efficient tuned genset.
