Approaching two years of grid storage operation.

To date we have accumulated about 40,000 kWh stored excess in the grid after almost 2 years of grid connected operation while powering 3 homes. Our local utility has taken about 12,000 kWh of this total to pay for our use of their wires to SEND them the power. They assess DEMAND / DELIVERY charges regardless of which way the power flows. At least they finally stopped taking our $ and are now just taking our stored kWh's to pay the commercial demand / delivery charges.

All the data logger can hold shows the seasonal water availability.

The data logged the last whole month shows the daily use patterns and the waning water as summer drought set in.
