The Sweetest Place on Earth meets clean energy. Derry Township offers solid solar economics at $0.21/kWh with PPL, but PPL has proposed tariff changes (~July 2026) that could slash net metering value by 60-80%. Lock in 1:1 rates now.

Solar panels in Derry Township cost $2.75-$3.10 per watt installed, averaging about $2.93/W. For a typical 13 kW system, the total cost is $38,090 before the 6% PA sales tax ($2,285), for an all-in cost of about $40,375. There is no federal tax credit for homeowners (25D expired Dec 31, 2025).
Yes. Derry Township is in PPL Electric Utilities territory, which has proposed tariff changes expected around July 2026 that would replace 1:1 retail net metering ($0.21/kWh) with hourly LMP-based credits ($0.04-$0.08/kWh). Systems installed before the change are expected to be grandfathered. This makes early 2026 critical.
With current PPL 1:1 net metering, a 13 kW system has approximately a 13-year payback period. This includes $0.21/kWh PPL rate, SREC income, and accounts for 6% sales tax and property tax increase.
Both Derry Township and Harrisburg are in PPL territory with identical rates ($0.21/kWh) and the same net metering urgency. Installation costs are similar ($2.93/W vs $2.95/W). The main advantage of Derry Township is slightly lower labor costs and larger suburban lot sizes that support bigger systems.
Hershey Entertainment properties (park, stadium, gardens) do not directly affect residential solar. However, the tourism economy has driven property values up, which means the property tax increase from solar is slightly higher. The tourism industry also provides seasonal employment that can supplement solar investment decisions.
Derry Township is served by PPL Electric Utilities at $0.21/kWh with 1:1 net metering. PPL has the highest PTC rate among PA utilities at $0.13/kWh for annual true-up. However, the proposed tariff changes make installation timing critical.
Yes, residential properties in these areas can install solar without restrictions. There are no special zoning prohibitions near commercial attractions. Township permitting for residential solar is the same across all of Derry Township regardless of proximity to tourist attractions.
