While I can see some allure in having your own solar array I still think it smacks more of good marketing than good application of the technology. From the marketing standpoint you get to sell a lot more goods, from panels to converters. From the application side you end up with a large number of installations that need service and such complicated by that large number of smaller installations.<p>I still think the idea of local solar power is good idea but should still be done in larger sites. There are certainly more sites that much more optimal than individual homes. Set up a co-op system where you buy shares in the installation and derive benefits from it
