Most people are surprised by what changes — and what doesn't — after solar is installed. The biggest surprise: Pepco doesn't show your solar production on your bill. If your panels covered all your usage, the kWh field simply shows blank. Here's exactly what to expect.
This homeowner went from $187.42/month → ~$23/month — saving about $165/month or $1,980/year. Their panels covered essentially all their electricity usage from Pepco. The only charge remaining is the mandatory ~$22 grid connection fee plus minimal supply charges.
Community solar vs rooftop solar — not the same thing on your bill. If you see a line like "Community Solar Bill Credit" on your Pepco bill, that is a subscription to a remote solar farm — not panels on your roof. With community solar, Pepco shows a dollar credit line. With actual rooftop solar, there is no credit line — the savings show up simply as lower or zero kWh usage from Pepco. They look completely different on your bill.

How do I find out how much my panels produced? Not from your Pepco bill — it won't show it. Your solar company provides a separate monitoring app (SolarEdge, Enphase, or similar) that shows real-time and historical production data. Always use that app to understand your solar output.
This mirrors the usage history table on page 3 of your Pepco bill. It shows how solar changes the pattern — summer months produce excess and credits build up, winter months may still draw some electricity from Pepco.
| Month | kWh from Pepco (before solar) | kWh from Pepco (after solar) | What happened | Est. bill after solar |
|---|---|---|---|---|
| May | 233 | — (blank) | Panels overproduced — credit built up | ~$22 |
| June | 784 | — (blank) | Panels overproduced — credit built up | ~$22 |
| July | 882 | — (blank) | Panels kept up with summer AC | ~$22 |
| August | 950 | 133 | High AC use — panels covered most of it | ~$53 |
| September | 337 | — (blank) | Panels overproduced | ~$22 |
| October | 210 | — (blank) | Panels overproduced | ~$22 |
| November | 283 | 80 | Less sun — panels covered ~70% | ~$41 |
| December | 650 | 430 | Short days — panels covered ~35% | ~$124 |
| January | 907 | 650 | Lowest production — heating draws a lot | ~$177 |
| February | 789 | 520 | Still cold — panels covered ~34% | ~$146 |
| March | 221 | — (blank) | Days getting longer — overproducing again | ~$22 |
| April | 184 | — (blank) | Panels well ahead of usage | ~$22 |
The annual pattern: Spring through fall — panels overproduce, usage shows blank, bill is ~$22. Winter — shorter days and heating draw more from Pepco, bill rises. Over the full year, most DC homeowners with a properly sized system average $40–$60/month instead of $150–$250/month.
Red flag: "You'll have zero electric bill." Anyone promising a $0 Pepco bill is not telling the truth. The ~$22 monthly customer charge is mandatory for all DC homeowners connected to the grid. A good solar company will tell you this upfront.
