I have a potential job where there is a flat (5 degree slope) metal roof constructed using sheets with folded metal seams. My thoughts:
- Using Uni-solar amorphous laminates laid between the seams looks a very neat solution. But I cannot get the numbers to work. Looking at the trade prices I could access last night the amorphous laminate rolls were getting on for twice as expensive per Wp as cheap solar panels. And the power density per unit roof area is less than panels. So apart from the aesthetic I cannot see why anyone would go the amorphous route.
- Considering putting a load of frames on roof to hold panels. eg console or schuco roof system. But do not want to increase roof loading by putting ballast up there. Schuco do a couple of clamps that fit directly onto metal seams with no roof penetrations. Anyone used a combination of frames and seam clamps to hold panels in landscape format on a roof?
Regards
