There are a variety of reasons why preventative maintenance is a vital aspect of the sustainability and health of PV solar systems. While solar is often marketed as a sustainable and resilient power generation tool, it does not go unscathed by external factors such as time, weather or equipment failures. For this reason, an effective preventative maintenance plan is required for the longevity and health of your system. Preventative maintenance differs from reactive or corrective maintenance as it gets owners ahead of repairs, keeps the system performing at as-built capacity and prevents larger, more damaging issues.
