With solar on your roof, some days you use more energy than you generate. Other days, you generate more energy than you use. Luckily, you’ll always get credit for the electricity that your solar panels produce, even if you’re not using the electricity at that moment. The reason is because we have policies that allow for Net Metering.
Net metering allows residential solar energy generators to offset their energy consumption with their energy production. Essentially, when your solar panel is producing electricity your electric meter runs backwards. When you’re using lots of power your electric meter runs forward. At the end of the month, your final electric bill with Pepco is your total usage minus the electricity that your solar panels produced (not including non-kWh surcharges, which all Pepco customers have to pay).
Monthly Electric Bill= [Total amount of electricity used] – [Electricity produced by solar panels] + surcharges
In DC, if on any given month you are a net energy generator (your solar system generates more energy than you use), your Pepco bill will be almost zero. Everybody has to pay a $13 distribution surcharge, but the excess electricity credits will be credited to the next month’s bill. It is like unlimited roll-over minutes, but for your electricity bill.
