Solar Prosumer Business Models in Sweden

Sammanfattning: In this research, four of the most common business models for Swedish photovoltaic (PV) prosumers were analyzed through a business case study. The costs and revenues related to adopting these prosumer business models for a household were examined and their economic viability was measured using the Net Present Value- and Payback method. The markets of PV and Battery Energy Storage Systems (BESS) in Sweden were researched in order to provide an overview of the potential for future prosumers in Sweden. Relevant actors and business models have been described and analyzed. Furthermore, Sweden’s energy structure as a whole and its potential transformation to a more decentralized and prosumer friendly system has been discussed. The business case study results show that the most economically beneficial business model for prosumers today in Sweden is through a Power Purchase Agreement (PPA). The business model where the prosumer owns a PV system proved to be the second best option which also was calculated to be economically beneficial. Leasing a PV system or owning a combined PV- and BESS were proven to not be economically beneficial.
