2 System Description
Reducing the emission of carbon dioxide and reducing other environmental emis-
sions resulting from energy conversion is becoming more and more important. Re-
newable energy sources can make an important contribution to solve this problem.
The direct conversion of solar radiation to electric energy (photovoltaics) will play a
substantial role in this essential matter.
Supplementary grid feeding includes the conversion of the DC voltage from the PV-
panel to grid conform AC voltage with so-called ”inverters“ and the subsequent con-
nection to the mains in the house distribution.
Here the solar energy system provides all consumers with electric power (household
devices, lights etc.). In case that not enough energy is produced the additionally nec-
essary energy is obtained from the grid. A potential surplus of energy is fed into the
local grid and is therefore available for other consumers. This way every single kilo-
watt-hour is used and the electricity companies power plants are relieved. In the
most simple case a grid connected solar energy plant therefore consists of two com-
ponents: the PV-panel and the inverter.
