Supervised Master Thesis Project to Evaluate Financial Payback Models for Photovoltaic Systems

Background: The annual amount of photovoltaic (PV) power in Europe is strongly increasing. Several companies offer PV system installations in the Swedish market. Typically, these offers include estimates of financial payback time for the customer investments.

 

Problem and goal: Short economic payback times are appealing to customers considering the purchase of a PV system installation. Therefore, PV installation companies might use overly optimistic calculation models for the economic payback time. Since PV installation companies use different models based on different assumptions to calculate the expected economic payback time, it is difficult for interested customers to compare their offers.

 

This master thesis is associated with SOLVE and will be supported by the Swedish Solar Energy Association.

 

The thesis should give an overview of the Swedish electricity market (electricity prices, tax regulations, etc.). The task is to compile a list of Swedish PV installation companies. These companies should be asked how they calculate the economic payback times when offering a new PV system installation. Additionally, calculation models from other institutions should be considered, such as the calculator from Mälardalens university.

 

The thesis should present the different calculation models and evaluate them. The ultimate goal is to propose a realistic calculation model, which could serve as a standard for calculating economic payback times for PV systems in Sweden.
