Application of solar energy in Harjakangas artificial groundwater plant

The purpose of this thesis was to research different options for the application of solar energy in a raw water purification plant in Harjakangas. The research will include both photovoltaic and solar thermal systems of different sizes, their prices, payback times and estimated productions. The studied photovoltaic system options were the sizes of 5, 10 and 20kW. The studied solar thermal systems included either 2, 3 or 4 collectors and the different options for the 4 collector system were studied separately. The thesis will first go through background information of the plant itself and continues to examine the collected data of electricity and heating oil consumption. After this is the solar thermal system simulation, options and payback times followed by the estimated production and payback times of the photovoltaic systems. An installation plan for the selected system written in Finnish will also be included as an appendix
