Policy & Economic Drivers
Government Initiatives
Recognizing the potential of agri-PV to contribute to renewable energy targets and sustainable agriculture, governments across the globe have introduced various initiatives to promote its adoption:
- Subsidies: In the United States, programs such as the Rural Energy for America Program (REAP) offer financial assistance to agricultural producers for renewable energy installations, including solar systems. Similarly, the European Union's Common Agricultural Policy (CAP) provides funding opportunities for integrating renewable energy into farming practices. In Asia, countries like Japan and China have established subsidies to encourage the deployment of agri-PV systems, recognizing their dual benefits for food and energy security.
- Net Metering Policies: Many regions have adopted net metering—a policy that allows farmers to send excess solar energy back to the grid in exchange for credits. This effectively reduces electricity bills and accelerates return on investment.
For example:
In the U.S., net metering laws in over 30 states help farms lower annual energy costs by hundreds or even thousands of dollars.
In Germany, farmers feeding solar power into the grid receive guaranteed feed-in tariffs, making solar a stable source of secondary income.
These policies are vital for encouraging long-term investments in solar energy systems for agricultural applications.
