Yes! You can put Solar panels on your agricultural field. There are two different ways in which you can install solar panels. One is for Own purpose to help your home or land with solar power and the other is for commercial purposes.
To produce 3000 kwp of solar energy per month a farmer would need to install 64 panels. If you need more power to be generated, then you need to increase the number of panels.
For 1 acre of land, the solar panels’ installation will charge you about $400,000 to $500,000. Larger farms need to spend approx. $500,000 per acre.
It depends on some reasons. For example, if you want your solar PV array to be ground-mounted on your land, or property is part of a world heritage site, or is listed, then permission should be needed in advance.
