Utility Power Station
An increasing number of countries are investing in solar power to produce electricity locally and reduce greenhouse gas emissions. Germany and Japan, the two leading countries in this field, have rolled out massive programs to equip households and companies with "solar roofs". In the case of households, these are just small installations, but when installed on an industrial building or in a field, they become genuine solar power plants.
Power is generated by photovoltaic modules on the roofs of industrial buildings, supplying some of the user's power needs. When there is little or no sun, a connection to the main grid provides a top-up. It is also possible to feed all power generated back into the main grid. The set-ups can then be referred to as photovoltaic power plants, just like the thermal power plants run by national producers.
