Strategic Adaptations in Operational Photovoltaic Projects: Impact of Actions on Photovoltaic Modules and Trackers of Energy Generation
Abstract
With technological advancements and the discontinuation of certain nominal power outputs of photovoltaic modules, operating solar plants may face the need for unplanned adjustments. In projects that rely on tracking systems to improve power generation curves, a high tracker failure rate can lead to an increase in OPEX. In these cases, replacing modules with higher-power versions can generate similar energy production, potentially eliminating the need for trackers. Furthermore, beyond the source of failure, to optimize the generation of photovoltaic systems, certain strategies can also be used, such as repowering or installing trackers in previously fixed structure locations. Therefore, the objective of this study is to compare workarounds or improvements between investments in photovoltaic modules or trackers to provide a technical basis for more efficient decision-making. This study could support a comparison between the long-term OPEX associated with tracker failures and the CAPEX investment required to upgrade to higher-power modules as a strategy to maximize energy generation, for example. Therefore, the study does not include financial data because they are variable and dependent on each technology chosen. However, it does demonstrate the technical analyses necessary for subsequent correlation with the value of each piece of equipment and technology to be implemented.
