Ray, Thinking of light weight PV modules reminds me that Uni-Solar is gone. Still the highest performance module I have ever tested. Being light weight and unbreakable was the icing on the cake if you had the real estate needed due to efficiency. My hat is still off to the brilliant inventor Stan Ovshinsky.
Jay, There are Uni-Solar PVL’s floating around. A coupe years ago I found enough to build a 4.4kW off grid system. If you have the length necessary, I would highly recommend using them instead of the Flexible modules you are considering. https://www.amazon.com/Uni-Solar-PVL-68-PowerBond-112-Inch-15-5-Inch/dp/B002MWDI44 Larry Crutcher Starlight Solar Power Systems On Mar 9, 2020, at 11:07 AM, Ray <r...@solarray.com> wrote: I 2nd Larry's experience. I've never seen any flex modules that have held up for more than a few years. Complete degradation in our high altitude UV environment. Glass with monocrystalline cells on the other hand: we still see some bronzed out Arco (before Siemens) modules that are over 30 years old with decent output. Another possible way to follow the curve is with smaller glass modules. We're having good luck with little modules down to 10 watts.
