Whether fair weather or foul, sustainable energy supply must be independent of natural fluctuations of renewable energy sources, such as sunshine. The coupling of “green” energy sources with reliable energy storage systems is a concept as necessary as it is well-known. “Currently single systems of photovoltaic cells which are connected together – mostly lead-based batteries and vast amounts of cable – are in use.
Solar cells and battery to be combined into hybrid system for energy harvesting and storage
