Operations & Maintenance

In the PV industry, the term O&M describes a set of activities, most of them technical in nature, which enable power plants to perform their task of producing energy in compliance with applicable rules and regulations’ “Services, Markets and Competitors, 2013-2017 report.”

Although PV has no moving parts, DC voltages of up to 1000V are present in daylight conditions. Systems should be checked at least once per year to ensure cabling and mechanical fixings are secure. It is also imperative to routinely monitor the performance of the system to ensure correct operation and that expected investment returns are achieved.

SSW staff are trained specialists in PV for both roof (however complex or easy to access) and ground mounted installations.
