SERIS operates a network of 25 irradiance stations in Singapore measuring global horizontal irradiance (GHI) across the city-state on a ~5 km x 5 km grid, enabling a live (i.e., real-time) solar irradiance map for Singapore based on actual irradiance measurements. The live irradiance map developed by SERIS can be seen at www.solar-repository.sg/solar-irradiance-map. A screen snapshot is shown below.
10 of these 25 stations are fully equipped meteorological stations, which also measure the following additional parameters:
- Global diffuse horizontal irradiance
- Ambient temperature and relative humidity
- Wind speed and direction
- Air pressure
Features of the real-time monitoring system are 1-second temporal resolution, automated daily downloads, graphical user interfaces, and precise time synchronisation. The system is very flexible and thus can also be applied to other data acquisition needs (e.g. building monitoring systems, BMS).
