研究目的
Investigating the efficiency increase in photovoltaic systems through the use of power optimizers in modular architectures.
研究成果
The modular architecture with power optimizers significantly improves photovoltaic system efficiency, especially in residential settings with frequent shading. However, the cost-effectiveness in large-scale plants with minimal shading is less pronounced. Future reductions in power electronics costs could enhance the viability of power optimizers across all applications.
研究不足
The study's simulations are based on specific scenarios and may not account for all real-world variables. The cost-benefit analysis of power optimizers is preliminary and may vary with market changes.
