Tilt Angle Optimality Criteria for Stand Alone PV Systems

引用

Journal of Power and Energy Engineering 2024年第3期12卷 1-18页

作者： Mohammad abu-Naser Faculty of Engineering and Technology Philadelphia University Amman Jordan

The conventional approach to optimizing tilt angles for fixed solar panels aims to maximize energy generation over the entire year. However, in the context of a supply controlled electric grid, where solar energy availability varies, this criterion may not be optimal. This study explores two alternative optimization criteria focused on maximizing baseload supply potential and minimizing required storage capacity to address seasonality in energy generation. The optimal tilt angles determined for these criteria differed significantly from the standard approach. This research highlights additional factors crucial for designing solar power systems beyond gross energy generation, essential for the global transition towards a fully renewable energy-based electric grid in the future.
