Depends on your power cpaomny, you'll have to check with them. My power cpaomny will buy the excess at wholesale while I buy at retail when I exceed my capacity. I believe by law all of them have to buy you power into their grid. The trick is to fill out their paperwork, get them to inspect your installation and approve it and having a dual meter installed ($300 from my power cpaomny) so they tell how much you sold vs. bought. http://feiwngri.com url=http://jddqfgigx.comjddqfgigx/url link=http://grraqobhx.comgrraqobhx/link
