There is not much land for large-scale power generation plants and “wasted areas” such as rooftops should be utilized to fulfill the increasing demands. Therefore, the study will focus on decentralized PV systems with integration of grid. The aim of the research is to better design the PV systems to help with sustainable transitions in Sweden.
However, there are still many challenges for PV installation in Sweden. This project explores the potential and feasibility of decentralized PV system in a Swedish context, including consideration of space, climate, infrastructure, and economics. A new model is developed and simulated based on a real Swedish case.
However, the PV system relies on local weather conditions. Although the studies on other countries could provide some insights, the real capacity and potential under Swedish contexts remain unknown. It is important to study local cases to fully understand how the PV systems would add value to achieve the goals.
The potential and feasibility of grid-connected PV system are measured within Swedish conditions regarding technical and economic aspects. A new weather model for high-latitude areas is developed. The impacts of climate change are evaluated based on historical and predicted big data. Economic analysis regarding consumer behaviors are analyzed.
