# Solar for West Penn Power Customers

West Penn Power, a FirstEnergy subsidiary, serves much of southwestern Pennsylvania: most of Westmoreland County, along with Fayette County, Greene County, and the city of Washington and the southern townships of Washington County. Their net metering program lets you earn credits for the solar power your home generates.

## Net metering with West Penn Power

West Penn Power participates in Pennsylvania's net metering program, which Pennsylvania requires of every investor-owned electric distribution company in the state. When your system generates more electricity than your home uses, the excess goes to the grid and you earn kilowatt-hour credits. Those credits offset your usage during times when your panels produce less, like evenings or cloudy days.

## Billing after solar

Your West Penn Power bill still includes a fixed customer charge and distribution fees. The generation portion (usually the biggest part of the bill) gets offset by the energy your panels produce and the net metering credits you have banked. During high-production months, your bill may drop to the basic service charges.

## Credit rollover and true-up

Credits are applied at the full retail rate during the billing period and carry forward month to month. Pennsylvania runs a 12-month rolling cycle, and at the annual true-up any remaining excess credits are compensated at the price-to-compare rate, which is typically lower than retail. We size every system to match your household's actual usage, so you are not overproducing and losing value at the lower payout.

## The interconnection process

1. **Site assessment and design**, we evaluate your property and energy usage to design a system that fits your needs. Whether your home sits on a borough street in Westmoreland County or a rural hillside in Fayette or Greene, we design for the roof and lot you actually have.
2. **Interconnection application**, we submit the interconnection application to West Penn Power on your behalf.
3. **Utility review and approval**, West Penn Power reviews the application to confirm the system meets their technical requirements. Most residential systems are approved without issue.
4. **Installation and meter upgrade**, once approved, we install the system and coordinate with West Penn Power for the bi-directional meter installation. Pennsylvania requires the utility to provide that meter at no additional cost.
5. **Permission to operate**, after a final inspection, West Penn Power grants permission to operate. Your system starts producing power and earning net metering credits.
