With large amounts of renewable power in power systems the need for balancing reserves on different time scales increases. If building-applied photovoltaic systems (BAPV) are integrated extensively in Sweden, future cities may become big power producers. The solar power variability and availability will then depend on the geographical extent of the city and the BAPV systems and how the weather changes over them. In this project we will characterize aggregated solar power generation from extensive city-scale BAPV in future scenarios for the city of Uppsala. We will develop models for geographically varying solar radiation and PV power generation on the city level and validate these with a monitoring network consisting of existing PV systems complemented with solar radiation monitoring. The project gathers a large number of systems that will be monitored, evaluated and used for modelling, and the participating system owners will actively engage in the project through workshops.
