Abstract

Solar energy has become an important source of power generation. Like all technologies, photovoltaic (PV) components have limitations in their usefulness and operational effectiveness. The rapid development of solar power technology, along with the costs and requirements for long-term maintenance, complicate the serviceability of these technologies when they become obsolete. As critical component spare parts are depleted, warranties expire, or original equipment manufacturers cease support for their legacy technology, it poses a significant risk to maintaining PV power plant operations. As a result, owners lack a comprehensive Decision Support System (DSS) to address failures in obsolete technology.

This dissertation aims to formulate a strategy that PV power plants can employ as they approach obsolescence. It consists of three essays evaluating DSS methods, policies, technology failures, and decision criteria. Each essay utilizes different methods, such as case studies, Failure Mode & Effect Analysis, and a Delphi study. All three essays reach similar conclusions and converge on the same main themes. Real options analysis is identified as an applicable DSS method along with the application of the Dupont analysis model. The most critical failures involve modules, inverters, and transformers. As these technologies approach obsolescence, maintaining an inventory of spare replacement parts is essential to mitigate the effects of potential failures, as well as having qualified technicians available. Policies supporting the retrofit or replacement of critical components will be necessary. Ultimately, stakeholders and regulators can apply the decision criteria in future case studies to develop strategies and policies for sustainable solar power generation.
