Agrivoltaics is the Future for Farming
May 16, 2023
Agrivoltaics, also known as solar sharing or dual-use farming, is a concept that harmoniously blends the generation of solar energy with agricultural practices. The idea is simple yet ingenious: install solar panels above the farmland and let crops grow underneath. This approach brings agriculture and renewable energy production together, creating a symbiotic relationship that benefits both.
The solar panels provide shade, which can reduce water evaporation and create a more favorable microclimate for the growth of certain crops. In return, the crops help cool the solar panels, improving their efficiency as solar panels tend to generate less electricity when overheated.

The Multifaceted Benefits of Agrivoltaics
Economic Advantages
Farmers adopting agrivoltaics stand to gain from multiple revenue streams. They can continue to generate income from their crops while also profiting from the sale of solar-generated electricity. Moreover, the shaded environment under the solar panels can reduce the need for irrigation, saving water and associated costs. in batteries for later use.
Environmental Impact
From an environmental perspective, agrivoltaics presents a win-win solution. Solar power is a clean, renewable source of energy that can help reduce greenhouse gas emissions. Additionally, by using the same land for both farming and energy production, agrivoltaics promotes efficient land use, which is crucial in a time of growing concerns over land availability and degradation.
Food and Energy Security
By boosting crop yields and generating renewable energy, agrivoltaics can contribute significantly to both food and energy security. This dual-use approach can help the U.S. become more self-reliant, reducing its dependence on fossil fuels and imported produce.
Successful Implementations of Agrivoltaics
Across the United States, several agrivoltaic projects have already demonstrated the viability and benefits of this innovative practice. In Massachusetts, a study conducted at the University of Massachusetts Amherst found that agrivoltaic systems could increase overall plant biomass by 65-110% compared to traditional agriculture.
In arid regions like Arizona, agrivoltaic systems have proven beneficial in reducing water evaporation, a crucial factor considering the increasing water scarcity in these regions. Researchers from the University of Arizona found that cherry tomatoes grown under agrivoltaic systems needed significantly less irrigation water compared to those grown under conventional methods.
The Future of Agrivoltaics in U.S. Farming
Looking forward, the potential of agrivoltaics in U.S. farming is immense. As solar panel costs continue to drop and their efficiency improves, more farmers are likely to adopt agrivoltaic systems. Government incentives and policies can further encourage this transition.
However, the road to widespread adoption of agrivoltaics is not without challenges. These include the need for technical knowledge to install and maintain solar panels, the initial setup costs, and potential changes to farming practices. To overcome these hurdles, continued research, farmer education, and supportive policies will be key.
Final Word on the Future of Farming
Agrivoltaics represents a groundbreaking approach to agriculture, one that could fundamentally change the way we think about farming in the United States. By combining renewable energy generation and food production on the same land, agrivoltaics can help farmers diversify their income, improve their crop yields, conserve water, and contribute to a cleaner environment.
While the initial investment in solar panels and the associated infrastructure can be significant, the long-term benefits of agrivoltaics make it a compelling proposition. As the cost of solar panels continues to fall and their efficiency increases, the economic feasibility of agrivoltaics is likely to improve further.
Moreover, agrivoltaics has the potential to make a significant contribution to food and energy security in the United States. By producing both food and renewable energy locally, we can reduce our dependence on imported goods and fossil fuels, creating a more self-sufficient and resilient society.
Beyond the farm, agrivoltaics also offers a viable solution to some of our most pressing environmental challenges. By promoting efficient land use and reducing greenhouse gas emissions, it can help combat land degradation and climate change, two of the most significant environmental challenges we face today.
However, realizing the full potential of agrivoltaics will require concerted effort and collaboration. Researchers must continue to study and refine this approach, policymakers need to create supportive regulatory frameworks, and farmers will have to embrace new technologies and practices. But with the right support and incentives, there’s no reason why agrivoltaics can’t become a standard feature of American agriculture.
In conclusion, agrivoltaics represents the future of farming in the United States. It’s a future where food production and energy generation go hand in hand, where farmers are also energy producers, and where agriculture plays a crucial role in our transition to a cleaner, more sustainable future. As we face the realities of climate change and resource scarcity, innovative solutions like agrivoltaics will be key to creating a more sustainable and resilient agricultural sector.
