Doesn the glazed front reflect light away from solar PV modules?
No. Solar PV modules constructed with a glass front have two characteristics that reduce light reflection. In order to optimize electrical yield, the glass is treated with an anti-reflective coating which greatly increases the transmittance through the glass, maximising the amount of light reaching the solar cells. Secondly, the outer face of the glass has a slight granular texture. The result is a matt-like finish – rather than mirrored. Again, this is actually intended to maximize yield. These two characteristics greatly reduce reflection from the glazed front face of solar PV modules when compared with conventional glazing.
