Water use and wastewater discharge are particularly relevant for the sustainable and reliable production of silicon based solar cells [19], [63], [26], [53].Periods with droughts or reduced water availability can compromise the operation of water and energy intensive industrial processes, in extreme cases this could develop into a factories unplanned shutdown.
The theory of solar cells explains the process by which light energy in photons is converted into electric current when the photons strike a suitable semiconductor device.The theoretical studies are of practical use because they predict the fundamental limits of a solar cell, and give guidance on the phenomena that contribute to losses and solar cell efficiency.

These parameters create an ideal environment for maximum solar panel''s performance – no shade, no cloud, no wind. The amount of power a solar panel generates under the Standard Testing Conditions becomes its maximum power rating or nameplate capacity. If a solar panel outputs 400 watts at STC, it will be labeled as a 400-watt solar panel.
