Assessment of photovoltaic application on a residential building in Gävle, Sweden

The paper presents a PV-based electricity generation system of residential building located at Norra Fiskargatan in Gävle, Sweden, and aims to examine the environmental performance of PV-based electricity generation systems by conducting a thorough investigation of photovoltaic utilities of residential buildings. This paper also investigates the carbon dioxide emission reduction due to the use of the PV will estimated for the service lifetime of the PVs (30 years). A comparison between carbon dioxide emission of a PV-based electricity generation system and an electricity grid, during the lifetime of the PV-system. The results show if PVs installed on residential buildings, the electricity produced by grid can be reduced and the carbon dioxide emissions will be saved from the electricity grid
