Photovoltaic
Principle:
Photovoltaics is the direct conversion of solar energy into electrical energy using solar cells. This technology is used for example in isolated applications, since the line length to the nearest grid connection would exceed or none is present. The solution also provides independence from high-maintenance fuel-generators, because the static energy generation, which means no mechanical movement occurs.
With the continuous technical progress solar cells today are not only more efficient but also shrink in size. This raises the possibilities of increasing use of photovoltaics.
