Brussels Photovoltaic Solar Monitoring Power Supply System

The system will be one of the largest ever installed in Europe with a power capacity of 200MW/800MWh and is the first BESS project Sungrow will supply in Belgium. Set for a grid connection in 2025 this project will deliver power to up to96.000households.

With our solutions for photovoltaic monitoring, you'll increase the electricity yield of your PV plants, optimising electricity production costs (LCOE) and the performance ratio (PR) and return on investment (ROI) of your system. In addition, our products enable the ongoing monitoring of individual PV strings or string groups.

The main purposes of a monitoring system are to measure the energy yield, to assess the PV system performance and to quickly identify design flaws or malfunctions. Many large PV systems use analytical monitoring to prevent economic losses due to operational problems.

Hence, the annual PR of a PV plant in Germany that is calculated on the basis of crystalline silicon sensors may be on average 2 to 4% higher than the PR based on a pyranometer measurement. This has to be taken into account when comparing the PR of an operating PV plant with the PR estimated in the energy yield assessment.

These measurement data are always obtained from an estimate based on an extrapolation, since Elia does not have all the measurement data at its disposal. Elia always tries to ensure that its forecasts and the corresponding measurements reflect the latest situation with regard to installed solar-PV power capacity in the Belgian control area.

In particular, best practices in PV monitoring have been documented based on the scientific state-of-the-art and in line with common practices in the field. Guidelines and examples have been presented for visual analysis of PV monitoring data by means of collections of stamp-like plots.
