PPL Net Metering at Risk: Act Before July 2026
PPL has proposed replacing 1:1 retail net metering with hourly LMP-based credits. Whitehall homeowners should start projects by April-May 2026.

Solar panels in Whitehall Township cost $2.80-$3.15 per watt installed, averaging about $2.98/W. For a typical 12 kW system, the total cost is $35,760 before the 6% PA sales tax ($2,146), for an all-in cost of about $37,906. There is no federal tax credit for homeowners (25D expired Dec 31, 2025).
Whitehall is in PPL territory. PPL has proposed replacing 1:1 retail net metering ($0.21/kWh) with hourly LMP-based credits ($0.04-$0.08/kWh) around July 2026. This would reduce net metering value by 60-80%. Systems installed before the change are expected to be grandfathered.
With current PPL 1:1 net metering, a 12 kW system has approximately a 13.3-year payback period. This accounts for $0.21/kWh PPL rate, SREC income, 6% sales tax, and property tax increase.
Whitehall and Allentown share the same PPL territory and rates ($0.21/kWh). Installation costs are virtually identical. Whitehall's advantage is its suburban housing stock — larger single-family homes with better roof access compared to Allentown's denser urban mix of row houses and apartments.
Many homes built before 1990 in Whitehall have 100-amp or 150-amp electrical panels that may need upgrading to 200 amps for solar. This typically costs $1,500-$3,000 and is included in most installer quotes. Homes built after 2000 usually already have 200-amp service.
A 12 kW system in Whitehall produces approximately 13.8 SRECs per year, worth about $386/year at current PA SREC prices. The PRESS Act could boost prices significantly if passed.
The MacArthur Road corridor in Whitehall is primarily commercial, but residential neighborhoods off MacArthur Road are excellent solar candidates. The commercial activity in the area means more solar installers are familiar with and active in Whitehall, which drives competitive pricing for residential projects.
