The solar radiation of the sun is available in abundance as an energy source. The total energy radiated onto the surface of the earth could meet humanity’s energy requirements seven thousand times over. (Source: Volker Quaschning, Regenerative Energy Systems, Hanser Verlag, Munich).
In recent decades, intensive work has been done on solar technology to make it usable in solar energy systems. Two main approaches can be distinguished: solar thermal energy and photovoltaics.
The solar modules, collectors and technology installed in solar energy systems are exposed to weathering around the clock. That means these elements must be protected especially against environmental influences – like humidity and temperature fluctuations. Especially in the sunniest areas on earth, there are extreme temperature differences between day and night. This puts high demands on the protection and on secure, long-term sealing of cables, modules and converters.
