O&M – operations and management

SES (UK) support our projects through ensuring that rigid and enforceable O&M contracts are in place with qualified and professional companies. Compared to other power generating technologies, solar PV power plants have low maintenance and servicing requirements. However, proper maintenance of a PV plant is essential to maximise both energy yield and the plant’s useful life. Optimal operations must strike a balance between maximising production and minimising cost. Module cleaning is a simple but important task. It can produce significant and immediate benefits in terms of energy yield. The frequency of module cleaning will depend on local site conditions and the time of year. As the level of module soiling is site-specific, the duration between cleans will vary significantly between sites. The frequency to clean modules will be dictated by factors such as site and surrounding area ground covering (dusty and arid sites will result in more soiling) and local rainfall patterns (drier areas will result in more soiling).
