Some people who are planning to put Solar Generators wind power generators at home are having second thoughts because of installation permissions. The truth is that planning requirements differ from one State to another. Some States don’t even require planning permits. But if it is indeed required, you can easily acquire it without any problems. Most home owners who installed wind power generators in their properties actually did not bother to seek for permissions (as long as they follow certain building guidelines). But if it is required in your area, applying for “post-dated” permit will not cause any major issue or penalty.
