Flexible vs. Rigid Solar Panels
We're evaluating our solar panel options, and I'm intrigued by the flexible Allpowers 100W monocrystalline panels. (5.56A, 18V) They only weigh 7lbs!
They're about $190 each (41" x 21"), but my thought would be that they could be rounded on the roof so that we could get sun sooner, and later, and have less weight on the bus.
BUT, do you think we'd actually be losing out on prime mid-day/overhead sun to charge the solar by having a few of the cells anchored to the edge area of the bus roof? (I don't think so, but would rather ask than assume!)
Our plan would be to drill the flexible panels into the roof with nylon washers, and be done. If we go with rigid panels, we'll have to add framing for a platform, which would be more weight for framing and for rigid panels.
It doesn't seem like many use the flexible panels. Is this because they're new-ish or more expensive?
