  • 13. Photovoltaic Photovoltaic “The trend is clearly to bigger plants – 100 MWp or larger.” Jens Vorbrodt, General Manager for Solar Power, Siemens Renewable Energy Division turns mass into energy. After convert- ing hydrogen to helium, the sun re- leases about 4 million tons per second of energy into space. From another perspective, even if you total all the en- ergy that will be obtained forever from coal, oil, natural gas and uranium, the solar energy that reaches the surface of the earth is about two times that amount, each and every year. Convert- ing that energy into electricity is, at least in principle, a fairly simple pro- cess involving a photovoltaic (PV) sys- tem (PV = “photo” [light] plus “voltaic” [electricity]) that utilizes cells, or semiconductors, on solar panels. Today’s solar energy facilities are effi- cient, extremely powerful and profit- able.

Urban Integration Urban Integration GIS Substations That Embellish, Not Blemish the Urban Streetscape In the past, high-voltage substations were always industrial- looking eyesores that, whenever possible, were banished from urban centers. Today, Siemens Energy’s state-of-the-art technology, engineering and design of gas-insulated switch- gear (GIS) substations mean that utilities can integrate high- voltage substations into urban settings in a way that makes them virtually invisible and entirely compatible with densely populated districts.
