Community Solar Resources for Delaware Customers with Delmarva Power
Delmarva customers in Delaware with community solar receive two bills each month for their energy: one from Delmarva Power (as usual) and a second from Nautilus Solar Energy.
Dual Billing
With dual billing, you’ll receive a statement from Delmarva and a statement from Nautilus Solar:
- Delmarva Utility Bill: Shows your total monthly energy usage. Your solar generation from your community solar farm (varies each month) is deducted from these charges, reducing the amount you owe to your utility company.
- Nautilus Solar statement: The solar energy generated by your solar farm is not free. Instead, it is billed separately by Nautilus at a 10-20% discount on what Delmarva would charge you.
Even though you are paying two bills, you are still saving money every month!
What Does Your Nautilus Solar Statement Look Like?

Your monthly statement from Nautilus Solar includes your share of solar energy generated by the community solar farm. You can find your generation details under "This Month's Solar Credits".
In the example above, 248.00 kWhs (solar credits) were generated by the solar farm and charged at the standard utility rates, but at a 10-20% discount (based on income eligibility)! This customer saved $3.52 this month with Nautilus Solar.
How does this work with your Delmarva bill?
It’s important to remember that the additional 248 kWhs you generated are not free. Instead, this energy is charged by Nautilus Solar at a 10-25% discount.
In the example below, Delmarva calculated that this customer had a monthly usage of 299 kWh. The remaining energy usage (51 kWh) is charged on your Delmarva bill.

The 248 kWhs deducted as a credit represent your solar generation.
Supply and delivery charges on your Delmarva bill are calculated for the total monthly energy usage (299 kWh), but the charge for 248 kWh is deducted.
This customer owes Delmarva $44.20, which is the total energy costs for usage and delivery charges not including your solar energy.
Supply Charges represent the cost of generating energy for your home or business.
Delivery charges represent the cost to move electricity through the grid to your home or business.
When will I receive my Nautilus statements?
Delmarva Power will likely send you a statement just a few days after your billing period ends. Your invoice for the same period from Nautilus Solar Energy may lag by 1-2 months. This delay reflects the time it takes for Delmarva to send us details about your monthly solar credit (energy) generation.
When will I receive my first bill from Nautilus?
Once we place you on an active solar farm, you can expect your first invoice within 1-3 billing cycles.
If your farm is still under construction, it may take several months before the farm starts sending energy into the electric grid. Rest assured, we'll will keep you updated on the status of your solar farm.
Frequently Asked Billing Questions
What Are Solar Credits?
Solar credits are the equivalent amount of energy generated by Nautilus Solar instead of Delmarva. This energy is deducted from your utility bill and charged by Nautilus Solar instead at a discount.
What Are Banked Credits?
Extra monthly energy generation is “banked” for use during months when your solar farm generates less. These banked credits are automatically applied when your allocated kWhs are less than your monthly usage. You only pay for these credits once they are used.
You do not need to take any action to use banked credits. Any unused credits will automatically roll over and never expire as long as you stay in the Delmarva service area.
Is Autopay Required
Yes. Autopay is required for all customers with a Nautilus Solar subscription.
