The most direct way to convert sunrays into electric energy is using the photovoltaic effect. Coefficients up to 20% make it possible nowadays to supply entire villages with electricity. Compared to a diesel power plant or a connection to the electric grid, a photovoltaic installation is often the most economic solution.
60 MW plants have already
proven successful in everyday duty. In countries with high sun
irradiation, photovoltaic is already competitive.
