Solar PV is well out of my budget range at the moment on my very slender student budget, but I've been researching concentrated PV methods for
building integration as part of my uni studies and wonder if anyone has tried to build a basic concentrator to boost power output?
This method would be ideal for something like the model that Swordbeast mentions...
At 10watts output it should be easy to boost that output x2 or x3 times at least by fabricating a very basic parabolic trough/dish from cardboard with
a surface area 2-3 times greater than the surface area of the PV panels and lined with reflective mylar (the stuff plastic-foil survival blankets are
made from) and the PV cell unit postioned facing-into-dish at the focal point...
...anyone willing to try boosting their cells this way in a field test?
incidentally, this wont damage the PV cells at a a few times magnification of cell surface area, but there is a tradeoff in that the cells will
operate at a higher surface temperature, and as a result will cause a small drop in photovoltaic efficiency
