Guidance note: Solar PV operation, monitoring, and maintenance specification

Solar PV systems are generally reliable, low-maintenance assets, but they still require appropriate monitoring, inspection, and maintenance to ensure they operate safely and deliver expected energy savings over their lifetime. Effective management helps organisations maximise performance, identify faults quickly, protect warranties, and maintain accurate records of their renewable energy assets.

This guidance sets out a proportionate approach to the operation, monitoring, and maintenance of non-domestic solar PV systems. It covers key areas including performance monitoring, routine inspections, electrical testing, fault response, cleaning, asset records, and contractor requirements.

Suitable for schools, offices, leisure centres, libraries, and other public sector buildings, the guidance promotes a risk-based approach that prioritises system visibility, prompt fault detection, and long-term asset value, helping organisations manage solar PV installations safely and efficiently.
