SUN & WIND provides technical support for the operation and maintenance of photovoltaic assets, electrical infrastructure and BESS, structuring management around availability, production, reliability, safety and warranty compliance indicators.

The goal is to preserve the asset's technical performance throughout its service life, identify deviations early and reduce production losses through preventive, predictive and condition-based corrective maintenance.
