that meeting such standards. This list will be identical to the list maintained
by the California Energy Commission. GWP reserves the right to adopt additional
codes, standards, and conditions at any time
- Must come with a minimum of a full 10-year warranty against breakdown or unusual

A separate meter panel to measure the PV inverter’s KWh output will be required.
The meter’s location will be in close proximity to the customer’s existing electrical
service. A GWP Electrical Service Planner will spot the meter. For residential or
30 KWdc or less customers only, both the main revenue meter and the PV output meter
will be radio meters to facilitate the reading of the meter registers to avoid meter
reading errors.
