Investigation of Energy Yield on Tromsøya by Mapping Solar Potential in ArcGIS

To reduce global greenhouse emissions, energy production from renewable energy resources should be markedly increased to supply the rising global energy demand. The aim of this study is to investigate the solar potential from rooftops on Tromsøya by creating a solar map in ArcGIS. The suitable areas for PV systems were determined by qualified estimations based on building area statistics and utilization factors. The energy load from Cruise ships was estimated by using given information from Port of Kristiansand. This study has created a 0.25-meter resolution solar map of Tromsøya. The result shows accurate results with a relative RMSE of 0.007 W/m2 when compared against averaged pyranometer values at Holt weather station. The resulting potential from buildings on Tromsøya shows that the PV energy yield with 10% integration scenario could cover the load from Cruise ships for all summer months during the tourist season. The solar fraction (SF) shows a positive energy balance between PV energy yield and Cruise ship energy load for all months, except from March, November and December.
