Instructions

Conventional light filters in solar technology are mainly different conditions of
cloudiness. The cloudiness range reaches from “clear sky” to light, medium, up to
strong cloudiness
Different light spectrums are lost through the filtering of the light. Depending on the
foil colour, different light spectrums are filtered out. Therefore the solar cell releases a
respectively different performance.
Here is an experiment to explore the effect of light filters:
