Whether ground-mounted solar panels require planning permission or not depends on several factors, including the size and location of the installation and local regulations. In some cases, planning permission may be required, while in others it may not be necessary.
In general, smaller ground mounted solar panels installations that are used for personal use, such as for a single household, may not require planning permission in some countries or regions. However, larger installations that are used for commercial or community purposes or that exceed certain size limits may require planning permission.
The specific regulations and requirements vary by country and region, and it's important to check with local authorities to determine if planning permission is required before installing a ground-mounted solar system.
In addition to planning permission, other permits and approvals may be necessary, such as building permits, electrical permits, and environmental permits. Again, it's important to check with local authorities and follow all necessary procedures and regulations to ensure a safe and compliant solar installation.
