Assess the energy output of your solar installation to detect anomalies, quantify their impact and correct them.

According to a 2015 European study of nearly 30,000 power plants, more than half of the solar installations on buildings show degraded performance. This leads to a loss of income for their owners or operators, which is often undetected because it is difficult to detect.
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.
The Helio Audit service remotely evaluates the performance of your installation without additional instrumentation and gives a quantification of losses broken down by cause.
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.

Our Helio Audit service
Helio Audit is a service offered for solar power plants in the built environment with installed capacities exceeding 35kWp. It is aimed at installations older than two years.
Helio Audit exploits the available data collected by any production monitoring system (OEM portal, SCADA, Monitoring System…) thanks to the advanced algorithmic core “Ab Initio” and gives you a precise diagnosis of the performance of your installation.
A true virtual checkup, this service can be part of preventive maintenance and help optimize corrective interventions on site to secure revenues and reduce maintenance costs.
