Silicon-based solar cells – characteristics and production processes
A set of photovoltaic modules of the PV system powering the triphase current
network must be divided into three segments of equal initial power. For the safety
matters, the PV system must also have earthing and a lightning arrester installation.
The configuration of a chosen PV system and its energy balance can be calculated
with the application of the commercially available computer software, such as PVsyst
5.03. [79].
One of the largest PV systems in Poland is located on the roof of a carrying
freezer owned by FROSTA in Bydgoszcz. The self-acting system with the power of 80,5
kW p , constructed on the surface area of 600 m 2 , consists of 366 mc-Si modules
produced by Conergy and it allows for a 30 % electric energy safe, necessary for
chilling the cold store. A big PV system integrated with a 53 kW p power network, built
of a-Si and mc-Si modules, is located on the building of the Faculty of Environmental
Engineering, of the Warsaw University of Technology. The largest - 1 MWp - grid
connected PV system in Poland is located in Wierzchosławice community
