Скачать или смотреть The Dual Harvest: Maximizing Land Water, and Profit with Agrivoltaics

Agrivoltaics, the practice of co-locating solar energy generation and agriculture on the same land, offers a range of "unbelievable" or surprising benefits that address major global challenges like food security, water scarcity, and renewable energy needs.

Here are some of the most significant advantages:

1. Massively Increased Land Use Efficiency (LUE)
Harvesting Twice: Agrivoltaics allows the same parcel of land to produce two monetizable outputs—food/crops/livestock and solar electricity—maximizing the site's productivity.

High LUE Ratios: Studies have shown that the total land use efficiency can be significantly high, with some reports suggesting an increase up to 186% compared to separate, standalone systems.

2. Enhanced Crop and Water Benefits
Water Conservation: The partial shade from solar panels reduces soil temperature and crop evapotranspiration (water loss through evaporation and plant respiration). This can lead to 30-40% less water consumption for irrigation in some arid regions.

Climate Resilience & Increased Yields: The shade moderates the microclimate, lowering daytime peak temperatures and reducing the risk of heat stress, sunscald, and frost. This can lead to higher yields (up to 15% in some cases) and better crop quality for shade-tolerant varieties (like leafy greens, peppers, or berries).

Broader Cropping Options: The moderated conditions allow farmers to grow a wider variety of crops, including those that might otherwise struggle in full sun.

3. Significant Economic Upside for Farmers
Dual and Diversified Income: Farmers gain a stable and predictable second revenue stream from selling the generated electricity or leasing the land, which offsets the volatility of crop prices and climate risk.

Reduced Operational Costs: On-site solar power can drastically reduce a farm's electricity bills for energy-intensive operations like irrigation, pumping, heating, and cold storage, often leading to 20-40% savings on energy costs.

Incentives and Funding: Access to government grants, tax credits, and premiums for green energy can further boost profitability and help secure financing for the initial investment.

4. Improved Ecosystem and Animal Welfare
Pollinator Habitat: Integrating native and pollinator-friendly vegetation beneath and around the panels supports biodiversity, which in turn benefits adjacent crop fields through increased pollination.

Animal Shelter (Ecovoltaics): The panels provide crucial shade and shelter for grazing livestock (like sheep), reducing heat stress and improving animal welfare, while the animals manage vegetation and reduce mowing costs.

5. Enhanced Solar Panel Performance
Cooler Operations: The vegetation and moist ground beneath the panels create a cooler microclimate. Since solar panels are more efficient at lower temperatures, this can sometimes lead to higher electricity generation (up to 3% more in summer months) compared to panels over bare ground.
