Evaluation Methods for Photovoltaic Installations on Existing Buildings at the KTH Campus in Stockholm, Sweden

The aim of this project is to investigate and evaluate the suitable area on the existing buildings at the Royal Institute of Technology (KTH) campus for the installation of solar PV panels along with the resulting potential for electricity production. The building evaluations were conducted to determine the available campus rooftops that could be utilized by eliminating those with visible contributions to shading. Two sample buildings were chosen for further simulation in the software PVsyst. The results of the simulation were further evaluated in terms of losses and applied to the whole campus suitable area in order to determine a total potential energy production. The resulting electricity production through PV installation was significantly lower in comparison to the total building energy consumption. Therefore, the importance of reducing energy usage and increasing energy efficiency is highlighted instead of focusing on renewable energy installations. This may result in a greater contribution from PV panels to the share of energy production in the future, making the campus more self-reliant and less dependent on the grid.
