IEA PVPS Task 13 Report: Guidelines for Operation and Maintenance of Photovoltaic Power Plants in Different Climates

This IEA PVPS Task 13 report provides guidelines for the operation and maintenance of photovoltaic power plants in different climates. Varying stress factors may contribute to the occurence of module failures. Knowing which to expect in different climate zones can assist operations and maintenance services to anticipate these stress factors, and act accordingly to ensure optimimum power plant output.

At present, comprehensive guidelines for climate-specific operations and maintenance (O&M) programs have yet to be developed. With this gap in mind, this report aims to provide comprehensive guidance for customized O&M service in seven different climate zones. These guidelines can assist PV plant engineers and designers, financing parties, and investors in designing and maintaining PV plants, as well as in determining operational risk related to investment decisions.

Three key messages are:

  • Operations & Maintenance (O&M) operators need to customize O&M services to the respective climates. This can be complemented by a comprehensive O&M agreement that includes future needs such as changing grid requirements.
  • The report established guidelines based on the seven different climate zones in which PV plants are commonly operated. Each of these zones is distinct and has its own risks and particularities.
  • Reducing both safety and performance risks by ensuring that personnel are adequately trained and equipped to perform O&M operations and by applying PV forecasting. Both are essential to reducing plant downtime and maintaining plant performance to specifications.
