This study proposes an integrated operations and maintenance planning model for PV solar plants, which are geographically distributed in different locations, to maximize total profit by minimizing total maintenance costs. The model harnesses sensor-driven data reflecting the degradation occurred in the performance of each unit including PV arrays, inverters, and transformers. It is characterized as a two-stage stochastic program in which demand and unit degradation are handled as uncertain; and optimal maintenance crew routing, preventive and corrective maintenance, and power generation decisions are made simultaneously. The experimental results show that the proposed model outperforms periodic and reliability-based maintenance policies in terms of optimum solution values obtained.
