Agrivoltaics: Dual-Use Solar + Farming Explained
How elevated solar systems can produce energy AND crops on the same land. System design, crop selection, and economics.
What Is Agrivoltaics?
Agrivoltaics (agro-photovoltaics or APV) is the practice of growing crops under elevated solar panels on the same land. Panels are typically mounted 2-5 meters above the ground on specialized structures, allowing farming machinery to pass beneath and sunlight to reach crops. It delivers dual income streams β energy generation plus agricultural yield β and can increase total land productivity by 60-70% compared to conventional farming or solar alone.
Best Crops for Agrivoltaics
Not all crops work. Best candidates: leafy greens (lettuce, spinach, chard), berries (strawberries, blueberries), tomatoes, peppers, aromatic herbs, ginger, turmeric, mushrooms. These benefit from partial shade especially in hot climates. Poor candidates: grains (wheat, corn) that need full sun, tall crops that interfere with panels. Livestock pasture (sheep grazing under panels) is also a common low-intensity application.
System Design Considerations
Key design parameters: panel height (2-5m typical, tall enough for tractors), row spacing (wider than ground-mount to allow light between rows), panel tilt (sometimes fixed seasonally rather than annually optimized), bifacial modules highly recommended (capture reflected light from crops/soil), water irrigation integration, pest protection netting attachment. Structural steel costs 20-40% more than ground-mount but generate additional revenue.
Economic Model
Typical agrivoltaic project economics: LCOE ~5-10% higher than optimized ground-mount due to higher structural costs. BUT: crop revenue adds $500-3000/acre/year net, land rent doubled or tripled (two uses of same hectare), policy support (France, Japan, Germany have APV incentives). Break-even typically 2-3 years longer than pure solar, but total land profitability 40-60% higher over 25 years.
JUSTSOLAR Agrivoltaic Experience
We have supplied modules for agrivoltaic projects in Pakistan (800kW solar + crop farming), Macedonia (200kW vineyard agrivoltaic), and China. Our TOPCon 640W is optimal for APV due to 80% bifaciality, durable frame, and good low-light performance. We provide structural design guidance for elevated mounting systems, water management integration, and crop selection advice based on your climate. CIF to any port.
