The only cloud that protects the profitability of your solar system

Continuous supervision of your solar installations in the built environment to detect anomalies in performance and advise you on corrective actions to be taken.







Energy output Monitoring vs. Performance Monitoring

The vast majority of solar power plants have a production monitoring system. These systems allow the operator and/or the owner to follow the production of a power plant park with a more or less fine degree of granularity (power plants, inverters, chains, modules), and to report alarms from the equipment.

For a large ground-based power plant, well instrumented and in a stable and controlled environment, production monitoring can provide relatively reliable performance monitoring.

On the other hand, in a built environment, subject to thermal phenomena, complex micro-climates and near-perfect masks, and where power plants do not have complete meteorological instrumentation,

A rudimentary inspection of production data fails to reveal the real performances of the installation.

In fact, more than half of the solar installations on buildings show degraded performances. This leads to a loss of income for their owners or operators that is often undetected because it is difficult to detect.

How to diagnose an underperformance of the installation when the output fluctuates strongly every day and key parameters are unknown?

Detection of anomalies, identification of causes and quantification of effects

The update of an underperformance must, to be usable, allow :

From performance monitoring to recommendations for corrective action

Helio Smart Guard collects your production data and transforms it into a real-time performance monitoring and diagnostic service.

Without additional instrumentation, Helio Smart Guard’s algorithmic core automatically detects anomalies and identifies their probable causes.

The quantification of losses by cause typology allows to issue action recommendations to the operator.

Helio Smart Guard monitors and reports certain warning signs of future failures.

Helio Smart Guard protects the profitability of the solar power plant by minimizing production losses and optimizing maintenance.

Our Helio Smart Guard Service

Helio Smart Guard is a subscription-based SaaS (Software as a Service) service for solar power plants in the built environment with a peak power of 50 kWp or more.

Helio Smart Guard exploits the available data collected by any production monitoring system (OEM portal, SCADA, Monitoring System…) thanks to the advanced “Ab Initio” algorithmic cores and provides you in real time a precise diagnosis of the performance of your installation with the probable causes of losses and recommendations for action.

A true guardian of the performance status of your fleet, Helio Smart Guard is part of preventive maintenance and helps optimize corrective interventions on site to secure revenues and reduce maintenance costs.
