Abstract

This study evaluates the potential and profitability of photovoltaic (PV) power production and

battery storage systems for five selected parishes within the Church of Sweden. Through

simulations and economic analysis, it is demonstrated that PV systems are generally more

profitable in southern Sweden (price areas 3 and 4) due to higher electricity prices. Despite that

the azimuth and tilt affect the production, installations on east and west-facing roofs remain

profitable. The study reveals that buildings with high self-consumption rates achieve better

economic outcomes compared to those with higher surplus production sold back to the grid.

However, battery storage systems are not found to be economically viable under current

conditions in this study. Scaling up the findings suggests that the Church of Sweden can

potentially produce 0.17 TWh of solar electricity annually, surpassing its 2027 target. Future

research should explore ground-based PV installations, energy communities, how benefits as sale

on the ancillary service market could effect the profitability of the batteries and integration with

electric vehicle charging infrastructure to enhance sustainability.
