Photovoltaics (PVs), which convert solar energy directly into electricity, are probably the most effective alternative energy source to conventional power supplies. The world demand for terrestrial applications of photovoltaic systems has increased, first for isolated areas and more recently in connection with grids in large PV roof programs, the most important cases being in Japan and Germany.
