What Will Waiting Cost You?
Enter your monthly Pepco bill. See what staying on Pepco's rate costs you over the next 10 years — versus locking in a solar rate today. Pepco's rate has gone up almost every year for the last decade.
Your bill
Use your average monthly Pepco bill. We'll do the rest.
DC average is around $180–$220. If you're not sure, use a recent summer-month bill.
Adjust assumptions (optional)
Defaults reflect 2025 DC reality: Pepco residential ~$0.16/kWh, up ~3% annually over the last decade. Locked-in solar rate is fixed at $0.10/kWh with no yearly increase — the same assumption used in our real proposals.

How these numbers are calculated
System size = (your bill × 12) ÷ Pepco rate ÷ 1,250 kWh-per-kW-year (DC solar production factor).
Pepco cost over 10 years = your annual bill compounded by the assumed annual rate increase (default 3%/yr), summed across 10 years — reflecting Pepco's historical pattern of raising rates.
Locked-in solar cost over 10 years = your annual production (kWh) × a flat $0.10/kWh solar rate, summed across 10 years with no yearly increase — sourced from the same PPA rate assumption our real proposals use by default.
The cost of waiting = Pepco cost over 10 years minus the locked-in solar cost over 10 years.
Estimates only. Actual production depends on roof orientation, shading, and tilt. Real numbers come from a free roof check at /survey.
