Abstract

Under-performance of a solar PV plant can have a negative impact on the financial returns for investors, owners, and insurers. The factors contributing to under-performance fall into four categories: overly optimistic prediction models, component degradation, operations and maintenance, and factors beyond the control of the plant owner such as environmental disaster and grid availability. To ensure optimal returns, the PV plant developer must select certified, reliable components and follow the relevant standards for installation and operation.
