Can sun rays reflected by a mirror to a solar panel generate electricity?
The reflectivity of the mirrors ranges from 40 per cent to 95 per cent. With a mirror of good reflectivity (95 per cent) the intensity of the reflected sunlight will not be affected much. The reflected sunlight can generate PV current almost as effectively as the incident rays.
In the countries located far away from equator (Norway, Sweden etc.) the intensity (power) of sun light will be low (100-300w/m). Here larger sized plane mirror reflects the sun light on to the PV panels. An array of mirrors focuses the low intensity sunlight on panels to boost PV current generation. A big concave mirror also enhances the power of solar rays at the focus.
