Overview

A PV solar plant’s preventive maintenance schedule typically includes a detailed visual inspection of the system, cleaning of equipment for exposure to the environment, random testing of components (with diagnostic follow-up / repair as relevant), and yearly / bi-annual calibration or servicing of equipment with reference to the OEM’s operating manual recommendations.

During the routine visual inspection, New Horizon Energy’s technical team will assess the need for module cleaning. Typically, ground mount and BIPV systems require more frequent cleaning than rooftop systems, however this also depends on the location of the installation (for example, is the solar facility located near a construction site or industrial area?).

Preventive maintenance also involves routine inspections by a ST-certified visiting engineer, abatement of weed growth, and periodic cleaning of drainage systems and retention ponds (primarily applicable for ground-mount or BIPV systems).
