Requirements for fencing around solar farms may vary depending on local regulations, project specifications and specific site conditions.

In many cases, solar farms do require fencing.Suitable wire fencing types are Chain link fence and welding wire mesh.

Here are a few reasons why fences are commonly used: 

1. Security: Fences provide a physical barrier that helps deter unauthorized access to solar farms, thereby reducing the risk of vandalism, theft or tampering with equipment.

Solar power plants often have valuable infrastructure and equipment, such as solar panels and inverters, that need to be protected.

2. Safety: Fences help ensure the safety of the public and workers on solar farms by preventing accidental access to potentially hazardous areas, such as electrical equipment, high-voltage components, or areas under construction. They act as visual indicators of boundaries and restricted access.

3. Animal isolation: Fences can help prevent wild animals, livestock, or other animals from entering the solar farm, which could cause damage to equipment or pose a safety risk. These animals may also be at risk of injury from electrically charged components.

4. Regulatory compliance: Local regulations or land lease agreements may require the installation of fences as a condition of approving or operating a solar farm. Compliance with these requirements is essential to ensure project viability and avoid potential legal issues.
