Enter your bill and we’ll size the array that would cover it, and show the gross value of that production at your rate. It does not net off the customer charge, taxes or what you would still draw at night — for that, use the bill savings calculator. Nothing is sent anywhere; this runs in your browser.
An estimate from your own numbers, not a quote, and not a savings figure. It assumes 400 W panels, an 80% system derate and no roof constraints. Your real number depends on orientation, roof area and your utility’s export credit. Savings are not guaranteed.

Why the number is what it is
Pepco buys from the same PJM wholesale market as every other Maryland utility. Capacity auction prices have climbed sharply and pass through to customers.
Large computing loads across the PJM footprint are arriving faster than new generation is being built, and the transmission to serve them is recovered from ratepayers.
Pepco adjusts its Price to Compare four times a year rather than twice. That means smaller individual changes but more of them.
The honest cost picture
BGE, Pepco and Delmarva Power are all subsidiaries of Exelon. Maryland’s Office of People’s Counsel has noted that since Exelon acquired BGE in 2012, electric rates have nearly doubled and gas rates have more than tripled.
The distribution side — the part you cannot shop away by switching suppliers — is where most of the increase sits. That is also the part solar offsets, because every kilowatt-hour your roof produces is one you do not pay distribution charges on.
In 2026 the PJM capacity auction cleared at its maximum price, driven largely by data-center demand arriving faster than new generation. Maryland’s Office of People’s Counsel estimated the resulting monthly increases at roughly $21 for BGE customers, $14 for Pepco, $18 for Potomac Edison and $4 for Delmarva Power.
You own the equipment, you keep any renewable energy credits, and you carry the maintenance responsibility. Installed pricing varies by roof, shading and system size.
$0 upfront. We install and own the system; you buy the power it produces at a rate set in your agreement, and you only pay for what it actually generates. The system owner carries maintenance for the life of the agreement.

You will still see ads promising a 30% credit that “ends December 31.” Read the date on them. If you buy a system today as a homeowner, you cannot claim that credit. What remains applies to the owner of the system — which, under a PPA, is us. SolarAmerica does not provide tax advice; talk to your tax professional about your situation.
Going solar with Pepco
When your panels make more power than your home is using, the extra flows onto Pepco’s grid and is credited on your Pepco bill under Maryland’s net metering rules. How much each exported kilowatt-hour is worth is set by those rules, and it is one of the biggest factors in how your system should be sized. How net metering works in Maryland.
Pepco connects home solar systems to its grid and credits the power you send back, but it does not install panels. State incentives are covered in our Maryland solar incentives guide, and SolarAmerica handles the Pepco interconnection application for you.
There is no separate sign-up. It is set up as part of the interconnection application your installer files with Pepco before your system is turned on, and SolarAmerica files it for you.

Pepco questions
Because the two numbers measure different things. Pepco's supply charge is lower; its distribution charges and riders are higher. What matters to your budget is the all-in figure — your bill divided by your kilowatt-hours.
Four times a year: March, June, September and December.
Yes. Maryland is deregulated, and switching suppliers changes only the supply portion of your bill.
About 60 seconds. No cost, no obligation, and we will tell you if solar does not make sense for your home.
