# Solar for Penn Power Customers

Penn Power, a FirstEnergy company, serves western Pennsylvania near the Ohio border: the city of Butler and most of central and northern Butler County, most of Lawrence County including New Castle, the inland townships of Beaver County, and Mercer County. Their net metering program lets you earn credits for the solar power your home generates.

## Net metering with Penn Power

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 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. Butler and Beaver county housing runs from Victorian-era homes to 1970s suburban builds, so we put extra care into roof assessments before quoting.
2. **Interconnection application**, we submit the interconnection application to Penn Power on your behalf.
3. **Utility review and approval**, 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 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, Penn Power grants permission to operate. Your system starts producing power and earning net metering credits.

## Penn Power service territory

Penn Power serves the city of Butler and most of central and northern Butler County, including Mars and Zelienople. It also provides electricity throughout most of Lawrence County, including New Castle, and serves Mercer County to the north. We install for Penn Power customers across Butler, Lawrence, and Beaver counties.

The boundaries matter in a few places. [Duquesne Light](/duquesne-light-solar) serves Cranberry and the southern corridor near the Allegheny County line, while Penn Power covers most of the central and northern county. In Beaver County, Duquesne Light serves the borough of Beaver along the Ohio River corridor, while much of the surrounding county, including Aliquippa, is on Penn Power. The two utilities split this area street by street, so we confirm the meter and account utility before designing the system.
