Utilization of Solar Energy in Liljeholmskajen

Sammanfattning: For the sustainable development of society it is crucial to find a way to decrease dependency on fossil fuels. Buildings today are big energy-consumers making this sector an important one to examine and develop further. This thesis investigates the possibility of using solar energy in Liljeholmskajen, a district in Stockholm, by considering technical, economic and environment aspects of its implementation.This report analyses different technologies for solar energy, with its focus on thermal collectors, thin film panels and monocrystalline cells. The analysis covers factors such as the efficiency, longevity, and specific constraints for the system. Further the area of Liljeholmskajen is studied, with a focus on the energy requirements. The analysis is based on three different buildings, which are chosen to be representative for the district. Based on this analysis, the total energy demand that could be met by each type of solar energy can be assessed, and their respective costs of implementation calculated.Based on these results conclusions are drawn, including how solar energy could be used in the area in the most effective way. This report suggests that the best solution today would be a combination of solar thermal collectors and thin film panels, although this also depends on the size of the possible investment.Furthermore for the future, if the existing rock-caverns in the area were converted into heat storage facilities, the heat storage wouldn’t be a limiting factor for thermal collectors anymore, and an increased usage of thermal collectors would therefore be recommended.
