I'll find out about the power outage question from my neighbor.

Things that were noted from the meeting this morning:

All of the engineering, install, monitoring is done by their own employees (solar city), no contracted out folks.
Production Guarantee, they pay if it under produces, even if a bad year and the clouds were out 50% of the time.
Excel charges x2 summer months rate, Tier 2 apparently?
PPA True up at end of year if the system produces more than used.
If your usage goes up, you pay excel for the energy used beyond the solar system, but this keeps you from the Tier 2 costs they charge.
