Tiivistelmä
The Bachelor´s thesis discusses the design of a 300 kW grid-connected Photovoltaic system in the largest logistics center of Posti in Tikkurilantie 148, Vantaa. Furthermore, an analysis of the payback time of the system was also carried out. The key goal of the environmental program of Posti is to reduce the carbon-dioxide emissions by 30 percentage by the year 2020 (compared to the 2007 level) by improving energy efficiency and using renewable energy sources with lower emissions levels.
The annual consumption of electricity in the logistics center is approximately 9200 MWh of which a small portion will be produced by the designed PV system in the near future as green energy. As a part of sustainability, Posti Group has managed to reduce the consumption levels significantly in the recent years. 1200 PV panels are going to be installed on the roof of the property and each panel will produce a maximum of 250 Wp resulting in a 300 kWp PV system. There will be a 14 PV array where each array will have 75-100 PV panels. The Junction box and Inverters will be installed in the upper floor around the center of the building to reduce the length of the cable. By the use of PVGIS estimation of power production, we can see significant power production from April to August.
Because of green electricity tariffs and investment incentives in renewable energy sources, this system will be vitally important in achieving its goal by the year 2020.
