This is probably exactly what happened. Those bad boys are not cheap to install either. Systems running well into the 30-50k levels to be paid over '20 years'

This is probably exactly what happened. Those bad boys are not cheap to install either. Systems running well into the 30-50k levels to be paid over '20 years'. The system I put in would have cost about 45k after 20 years if I had taken their loan. I can buy all the electricity I need and 3 of my neighbors for that. As I had the money for up front it ended up costing me 16. Even then the 'ROI' is rubbish. Still cool to get a bill that is just interconnect fees though.
