Core Issue: Agricultural greenhouses need to ensure crop light requirements while also seeking to increase revenue through photovoltaic power generation. However, conventional modules have a high shading rate, which impacts crop growth.
Solution: Utilizing “semi-transparent photovoltaic modules combined with a strategic spacing design,” module transmittance is controlled at 30%-50% (suitable for both light-loving and shade-tolerant crops). The roof angle is optimized for local latitude (e.g., 25° for areas at 30° north latitude) to ensure normal growth of crops beneath the greenhouses. The system is connected to the grid, and the power generation revenue supplements agricultural investment.
Implementation Results: The greenhouses generate an average annual power generation of 800-1000 kWh/㎡, while crop yields remain at their original levels (e.g., strawberry and vegetable yield reductions are less than 5%). Farmers’ annual income increases by 20,000-30,000 yuan, achieving dual benefits from “agriculture + energy.”
