Sustainability is important and right now solar is not sustainable in the usa. As life of solar panels is about 25 years. And generally speaking we rely on china for the panels and parts.

Putting the national power grid at the mercy of a country that is not officially an enemy yet certainly is not a friend...does not seem wise.

Glad to see it is more economically worth it, till the special credits expire. Would like to see more solar houses. That makes for a more robust power grid if international relations deteriorate. A few houses going off grid..accommodations can be made.
