Here is a short blow by blow example of some DIY Uni-Solar enthusiasts installing a BIPV smart roof in Hawaii. First the gable flashing is tacked on, then the cut panel starter strip is slid under the flashing and the clips screwed on. First panel is cleaned with alcohol and the laminate is applied starting with the top foot then the laminate is rolled up from the bottom and the peel and stick plastic backing is pulled off while the laminate is rolled out into the standing seam roofing pan. There is a twenty year warranty when they are installed correctly on approved substrates. The laminate must be 100% bonded down to the Galvalume roofing pans which are flat as can be. They can also be applied to EPDM roofing membranes. There are 18 total and they will charge 8 L16 batteries @ 24 volt nominal with an Outback FX2524 and the Outback FM-80 charge controller with 80 amps and maximum power point tracking. The Uni-Solar laminates are wired in series strings of three each with 6 circuits landing on 8 amp breakers each in the combiner box. The MPPT charge controller is a modern device which allows wiring PV laminates at 72 volt nominal and down converting the voltage and up converting the amperage at the maximum power point. This gets you 15% more power into the batteries. It’s like hitting a tennis ball in the sweet spot on the racket. The roof charges your batteries down below; such a beautiful and simple concept.

Just call one of your local metal roofing suppliers in your area and ask for Galvalume or Zincalume Kynar painted 16″ minimum standing seam concealed fastener roofing panels 24 G. The pans must be flat as can be. Typical cost is $3.50/LF so an 18’3″ panel will cast about $65 plus clips and screws.

I bought three of the Unisolar 124 laminates to experiment with. Where did you get the roofing trays to put the laminates in? Thanks.
