Solar Panels

Solar (photovoltaic) energy systems use the sun's energy to produce electricity

There are two basic types of solar panels:

  1. Systems connected to the power grid.
    • Customers wishing to connect to the power grid should apply through the Renewable Energy Connection online portal.
    • PPL has to approve this system for the safety of our customers and crews.
    • If the system is equipped with the proper inverter, surplus generation could be sold back to the utility or alternate supplier.
  2. Stand-alone Systems.
    • Ideal for providing power applications such as area lighting or power for use at remote locations.
    • These systems have battery backup and charging systems.
    • The power supplied by the system is the sole source of power to the device it powers.

If you want to connect to the PPL Electric Utilities Transmission system or to participate in the PJM market, please contact PJM.


How much energy will your solar panels produce?

The potential kilowatt-hour output can be found by multiplying the number of sun hours per day in your geographic area (average of 3.5 per day in northeastern Pennsylvania) by the kilowatt-hour output of the system. This number represents the maximum potential of a properly installed system in a location that has ideal solar conditions. Actual output may vary depending on site factors.

(Number of sun hours) X (System output in kWh) = Total kWh

To properly evaluate the kilowatt-hour output of a solar generation system, the proposed location of the photovoltaic panels needs to be evaluated using a solar pathfinder. A pathfinder evaluation takes into consideration the site’s geographic location, collector orientation and shading potential. The evaluation gives the number of sun hours available on a monthly basis for the entire year.

Installation Requirements

  • Photovoltaic panels can be mounted on a roof or on the ground. Ask your installer for guidance.
  • A UL and IEEE certified inverter is required for interconnection to the grid.
  • The proposed area where the photovoltaic panels are to be located should face due south and receive the maximum amount of sunshine on a daily basis for both the winter and summer season.
