Helio Audit
Indeed, how to diagnose an underperformance of one’s installation when the output fluctuates so strongly every day?
The output of a solar installation depends on the local weather and environmental conditions and its operating condition. Without meteorological stations on each site, the irradiation and temperature of the panels are unknown and the complexity of the built environment makes the direct use of satellite data wholly inaccurate.
It is also difficult to distinguish between “normal” losses such as thermal losses due to coupling with the building, shading (near or far) or the natural rate of degradation of the panels and losses resulting from anomalies or defects in design, materials or fouling.
When underperformance is suspected, however, it is necessary to identify and quantify the effects of each cause separately in order to be able to define an optimized action plan.
Thus, the Helio Audit service establishes an “a priori” diagnosis and allows you to judge the technical and economic relevance of a possible corrective intervention on site.
The analysis of plant data can also help to identify signals that could indicate a failure.
