video’s of home made solar panels mounted on roof. 2 larger are 72 cells and the one small one is 36 cells. So It’s like having 5 panels . Had to go with the 2 larger ones because of glass size. I used storm door windows that are tempered glass. There is probably a slight loss because it is not white or solar glass but that is expensive. I am getting about 30 amps max out of them on a good day . adding the MPPT controller helped a lot. I will have another video here of that.
