6 FAQs about [Principle of solar photovoltaic power generation for farmers]
What is solar photovoltaic (PV)?
FAO recognizes the solar photovoltaic (PV) system as a technology that is already providing energy services in many sites around the world, mainly at the household level, and draws attention to its potential in fostering new income-generating activities and higher agricultural productivity.
Is solar photovoltaic a good investment for farmers?
This site is protected by reCAPTCHA and the Google Privacy Policy and Terms of Service apply. Even without renewable energy incentives, solar photovoltaic (PV) power generation can offer a sound return on investment for farmers, following the dramatic fall in its capital cost.
Should a farmer own the land for a solar PV system?
In many cases, however, the land is not owned by the farmer. Ownership of the PV system is probably less common for larger agrivoltaic systems as well, increasing the likelihood of external investments. Partial ownership could help to maintain the incentive structure for the synergetic dual use of land in this case.
Are agrivoltaic systems a solution to agricultural lands and forest invasion?
The rate of solar power generation is increasing globally at a significant increase in the net electricity demand, leading to competition for agricultural lands and forest invasion. Agrivoltaic systems, which integrate photovoltaic (PV) systems with crop production, are potential solutions to this situation.
Can solar PV help farmers get to net zero?
There is a long history of food producers using the sun’s energy for growing and drying crops, solar PV adds a modern twist to agricultural landscapes and the farmer’s relationship with the sun. Solar PV systems are versatile and scalable and warrant serious thought as part of any ambition to get to net zero.
