Micro production of solar electricity in multi-family buildings

This thesis is commissioned by the Swedish electricity trading company GodEl with the purpose of evaluate solar electricity in multi-family buildings in the Stockholm region. The prices of solar panels have dropped recently due to the advances in technology, but the installation rate in Sweden remains low. It is therefore interesting to study the profitability of solar electricity today, and if it is profitable enough to install based on profitability alone and not simply due to environmental considerations. Therefore this thesis first studies the profitability of solar panels based on a simulation of electricity production and consumption for multi-family buildings this region. The study concludes that solar electricity can be profitable in the Stockholm region under certain conditions; all of which have to be favourable for profitable solar electricity. The thesis also studies the opinion of the company's costumers concerning solar electricity. The study concludes that they are very positive to solar electricity in general, but are uncertain of the profitability. The thesis summarizes the results through suggestions to GodEl of how they could assist their customers in questions regarding solar electricity.
