Solar radiation and building integrated photovoltaic power generation datasets at zero emission building laboratory,...

This paper presents a high-resolution one-hour time interval, three-years datasets of solar irradiance and corresponding photovoltaic power generation collected from a Zero Emission Building (ZEB) located in high latitude climate at Trondheim, Norway. The datasets (one dataset on solar irradiance and a second dataset on PV power generation) include measurements from facades oriented in the North, East, West, South as well as Pergola shade (60° tilt) and Roof top (30° tilt). The datasets capture real-world operating conditions, including seasonal variability, low solar angles, and the influence of snow and cloud cover as well as building shading providing a comprehensive basis for evaluating PV system performance under challenging climate conditions. By combining measured solar radiation with synchronized PV output, the datasets enable detailed analysis of system efficiency, performance ratios, and temporal dynamics across multiple scales. The datasets support statistical assessment of inter-annual variability and offer insights into potential performance degradation and system reliability. The datasets are useful for validating and calibrating solar energy models, as well as for developing and benchmarking forecasting methods. It is expected to support further research on a wide range of applications, and policy analysis aimed at advancing sustainable and zero-emission buildings.
