Simulating monitoring

4 June 2013

smartblue AG, a provider of service and maintenance concepts for photovoltaic systems, is now integrating satellite data in its Smart Control monitoring solution. The new module is part of the monitoring solution with immediate effect and makes it more reliable and precise than most radiation sensors. In the case of extended monitoring, the solution simulates the output that solar energy systems are intended to yield at a certain point in time. This is performed with a high degree of accuracy based on the evaluation of data from weather satellites, and only the solar radiation that reaches the system is taken into account in the calculation. Each solar power plant is simulated on an individual basis according to its size, orientation, tilt, etc. Calculated at regular intervals, the performance values are precise within a few percentage points and can be referred to as comparative values. If the deviation from the energy that is actually generated falls outside a small tolerance threshold, the owner of the system or service technician is automatically notified. Taking into account the potential yields, the monitoring and optimisation of PV systems have a key role to play: A decrease in the yield of just a couple of percentage points can result in the system having a negative overall yield. While a total failure can also be easily detected via manual readings, it’s the small but continual losses that are of vital importance for monitoring photovoltaic systems.
