Interesting stuff, but there are financial assumptions being made here that should be examined. 1. The 25-year ROI is tied to the projected price of electricity moving forward. It is simple market issue that if and when more and more people start using these systems, the utility-based kW price will (must) come down and therefore, the ROI will change, perhaps dramatically. 2. What about the opportunity costs of such a significant financial commitment? Have they been examined in any way?
