Abstract [en]

The purpose of this thesis is to examine the possibilities to incorporate solar heat and thermal energy storage to a newly produced apartment block with a low energy use. From HFAB we were given the block “Jordmåen” in Halmstad. “Jordmåen” that was complete in 2015, consists of 4 apartment buildings and fills its need of 669 MWh of thermal energy withdistrict heating.

The thesis describes a theoretical study about solar heat and thermal energy storage. To establish a usable area for the solar panels, measurements of an actual building have been made, given to us by HFAB. We use actual data from the Buildings but with the assumption that the buildings aren’t built. Solar panels from ASV Solar are used in the measurements, and possible energy production has been calculated with the program PVGIS. The economic calculations are based on two methods, Pay-off and value approach.

“Jordmåen” would be able to cover its heating needs from April to September and provide an addition of thermal energy for the remaining months, with 932 m2 of solar panels connected to a borehole thermal energy storage (BTES) with a degree of efficiency of 65 %. The payoff time for this system varies between 9 to 14 years, and the present worth varies between - 1 027 281 kr and - 22 343 kr, with the best outcome in a scenario with roof integrated solar collectors because of the savings of expensive roof material.

The conclusion is that solar heat combined with heat storage is not a profitable investment when not using the full capacity of the thermal heat storage. Although some parameters are missing to establish the real profit we advise to do a more in-depth investigation to get a more accurate outcome.
