Agrivoltaics: Farming and Solar Power on the Same Land

The idea of combining solar energy generation with agricultural production on the same land — called agrivoltaics — seems counterintuitive at first: don't crops need unobstructed sunlight? The reality, demonstrated by a growing body of research and a significant number of operational projects, is more nuanced and genuinely exciting. Under the right conditions, solar and farming can coexist beneficially, producing more food and more energy together than either could alone on the same land area.

The Basic Concept

In agrivoltaic systems, solar panels are elevated above the crop canopy on taller mounting structures than standard ground-mount systems, allowing crops to grow beneath. The panels are often tilted or spaced to allow a portion of sunlight to reach the soil while also generating electricity. Some systems use bifacial panels that capture reflected light from below, optimizing energy production while allowing more light through. The term "agrivoltaics" was coined by German researcher Adolf Goetzberger in 1981, but practical development accelerated dramatically after 2010 as solar costs fell and food security concerns increased.

Crop Benefits From Partial Shading

Many crops perform better with some shade, particularly in hot climates. Direct sunlight can cause heat stress, water stress, and sunscald in susceptible crops — shade-tolerant vegetables like lettuce, spinach, and herbs often grow larger and more vigorously under agrivoltaic arrays than in full sun. Research at the University of Arizona has demonstrated excellent production of tomatoes, chilies, and herbs under agrivoltaic panels, with some crops showing yield increases of 30-60% compared to unshaded controls. The panels also reduce soil evaporation, significantly lowering irrigation water requirements — a major economic and environmental benefit in arid farming regions.

Examples and Scaling

Agrivoltaic projects are operating across multiple continents. In Japan, the "solar sharing" model has over 2,000 registered installations, primarily growing vegetables, tea, and fruit under elevated panels. In France, Sun'Agri operates systems for viticulture and orchard crops, with data showing reduced heat stress during extreme weather events. In the United States, InSun has developed grazing-compatible systems that double as habitat for pollinator species, and several states have specific incentive programs for agrivoltaic projects.

Economic and Land Use Logic

The economic case for agrivoltaics is strongest in regions where both land and water are scarce and valuable. A farmer who can generate solar income from the same land as crops essentially hedges against agricultural price volatility with a stable, long-term energy revenue stream. Studies modeling dual land use efficiency — sometimes called the Land Equivalent Ratio — have found that agrivoltaic systems can produce more combined agricultural and energy value per hectare than either land use separately, effectively increasing the productive capacity of each acre of farmland.

Looking Forward

As solar development faces increasing land use conflicts and competition with food production, agrivoltaics offers a pathway to expand solar capacity without sacrificing agricultural land. Regulatory frameworks in several states and countries are evolving to specifically accommodate and encourage agrivoltaic projects. The technology is well-matched to the dual pressures of climate change — which makes solar energy increasingly necessary — and extreme heat and drought, which make shade and water conservation increasingly valuable for agriculture.
