Doesn the glazed front reflect light away from solar photovoltaic (PV) modules?
Not really, no. Solar PV modules constructed with a glass front have two characteristics that reduce light reflection. In order to optimise electrical yield the glass is treated with an anti-reflective coating which greatly increases the transmittance through the glass to maximise 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 surface which again maximises yield. These two characteristics greatly reduce reflection from the glazed front face of solar PV modules when compared with conventional glazing.
