Design Considerations For Agrophotovoltaic Systems: Maintaining Pv Area With Increased Crop Yield
2019 IEEE 46TH PHOTOVOLTAIC SPECIALISTS CONFERENCE (PVSC)(2019)
摘要
Land use constraints have motivated investigation into the spatial coexistence of photovoltaics and agriculture. Existing experimental work has emphasized fixed south-facing configurations with traditional commercial panel shapes, and modeling work is sparse. Previous work also concludes that agriculture-photovoltaic (agrophotovoltaic) systems either decrease crop yield or are limited to shade-tolerant crops. In this work, we explore the effects of different PV array configurations and panel designs on field insolation. We find that east-west tracking configurations outperform fixed south-facing configurations due to shadow migration paths. Additionally, we show through optical modeling that utilization of mini-modules in patterned panel designs may create more optimal conditions for plant growth while using the same area of PV, thus improving the land-use efficiency of the agrophotovoltaic system.
