This idea is to create a community owned solar array where for every $800 contributed, funders become the owners of one solar panel and the stream of energy revenues it creates. The energy generated by the solar panels is then sold to BC Hydro under their net-metering program with the resulting revenues being distributed among the owners.
This ideas was successfully implemented in Rockford, Minnesota. In that project, $46,000 was raised to build a 147 panel array ($869 per panel with 2012 solar panel technology). Based on the prevailing electrical energy cost in Minnesota, owners estimated that it would take them about 12 years to pay off the panels and then they would generate a stream of free energy cash flows from that point onward.
