FAQ

Higher OPV coverage percentages lead to a reduction in overall energy consumption in both locations. However, when looking at the illumination levels and weight of the tomato crop the tendency is opposite, resulting in insufficient illumination levels for some periods. Our 75% transparency design carefully balances energy generation with crop needs, ensuring adequate photosynthetically active radiation for vegetable growth. The project achieved a 15-20% increase in vegetable production compared to traditional greenhouses through optimized spectral transmission and intelligent shading systems that adjust based on seasonal light requirements.

Yield reductions are observed in light-dependent crops under high shading intensities, underscoring the need for tailored approaches. Crop yields are negatively affected by shading for all simulated crops in both the 1P and the 2P case. However, our project mitigates this through spectral optimization technology that adjusts transmitted light spectrum based on photosynthesis needs and intelligent shading systems that automatically adjust light transmission during high summer temperatures. The 20KW per greenhouse capacity is carefully sized to maintain optimal growing conditions while maximizing energy generation.

The structure is engineered to withstand winds ≥50m/s and snow loads ≥3.5kN/㎡, exceeding Northern China’s snow load standards. The design includes reinforced aluminum frames, tempered glass panels, and secure mounting systems that protect both the photovoltaic components and the greenhouse structure. During extreme weather events, the intelligent system can automatically adjust panel angles and activate protective measures to minimize damage while maintaining structural integrity for continuous agricultural operations.

AV systems improve WUE by 20–47 %, lower air and soil temperatures by 1–4 °C, and enhance crop resilience in water-scarce regions. Our project achieves 40% water savings through smart irrigation systems and improved microclimate control. The annual coal equivalent savings of ~272 tons represents significant energy conservation, while the photovoltaic system generates approximately 680,000 kWh annually, creating a net-positive energy facility that supports both agricultural operations and grid contribution.

The project generates annual power revenue of ~$48,000 and agricultural revenue of ~$210,000, with additional cost savings of ~$35,000 in electricity and fuel costs. The comprehensive payback period is 6 years, significantly faster than solar-only installations due to the continued agricultural productivity. Farmers benefit from dual policy subsidies for both agriculture and solar, plus the 200% increase in output efficiency per unit land makes this model highly attractive compared to traditional farming or solar development alone.

Maintenance includes regular cleaning of photovoltaic surfaces to maintain optimal transparency and energy generation, monitoring of the intelligent temperature/humidity control systems, and inspection of the anti-condensation coating to prevent water droplets from affecting light transmission. Keeping your solar battery out of the greenhouse is a good idea since the high humidity could cause problems over time. The modular installation design allows for rapid component replacement without affecting agricultural production seasons, and the environmental monitoring systems require calibration for accurate greenhouse climate control.

The spectral optimization technology adjusts the transmitted light spectrum based on specific photosynthesis needs of different crops. Different vegetables require varying light wavelengths for optimal growth – leafy greens benefit from blue and red spectra, while fruiting vegetables like tomatoes need broader spectrum coverage. The system can be programmed for different crop rotation schedules, automatically adjusting transmission characteristics to match the growth stage and variety requirements, ensuring optimal photosynthetic efficiency throughout the growing cycle.

The project became a national benchmark for agro-photovoltaic integration, expanding to 200+ agricultural cooperatives within Shandong Province and being selected as a demonstration base by the Ministry of Agriculture and Rural Affairs. It provides a replicable green development model for rural revitalization strategy, increasing local farmers’ annual income by ~$4,200 per household. The success has driven modern agriculture development in surrounding villages and created 50 new employment positions, demonstrating how technology can simultaneously address energy transition and agricultural modernization goals.
