Questions About Your Duke Energy Bill, Answered

  1. How Do I Read My Duke Bill Once My Home Solar System Is Working?

    Duke Energy will measure the difference between the number of kilowatt-hours your home solar system produces and the amount of electricity you use from the grid. This difference is called Net Energy Metering or NEM, and Duke Energy uses it to calculate your solar bill.2

    Since solar energy only affects the kilowatt-hour part of your bill, some elements will stay the same, like your monthly service charge to keep Duke Energy’s grid healthy, as well as your transmission and distribution costs. See a sample Duke Energy bill.

  2. What Happens to the Excess Energy My Solar Panels Produce?

    Under NEM, you may be eligible to offset your electric bill when your home solar system generates more kilowatt-hours than you need, yet, you must enroll in Duke Energy’s Net Metering Rider which works together with Duke Energy’s standard electric rate.3Learn the details about Duke Energy’s Net Metering Rider.

    If you have excess energy after offsetting your current monthly bill, you can roll it over to your next billing month. Any excess energy remaining after a year will be paid out to you at the current kilowatt-hour rate, and your net metering balance will reset to zero.4
