http://www.posharp.com/photovoltaic/panelefficiency/database.aspx WebWith a 5.9V MPP voltage, the system will still be creating 88% of maximum power. We need to strike a balance between 5.3V and 6.6V, but not too low as the V MPP in extreme cold is 6.1V or so. So the effective range of MPP voltages we can choose for our panels is somewhere between 5.3V and 6.1V.
