Q: How does Potomac Edison net metering work in Hagerstown?

Potomac Edison (FirstEnergy) provides net metering for residential solar customers under Maryland law. Surplus solar exports are credited at the retail rate (~$0.14/kWh), with credits rolling over month to month. The lower rate compared to Pepco (~$0.18–0.20/kWh) or BGE (~$0.165/kWh) means each net metering credit is worth less in dollar terms — a key reason why payback periods are longer in Western Maryland than in the DC suburbs.

About This Guide

Going Solar in Hagerstown, MD

Hagerstown is Western Maryland's largest city — and an underserved solar market. While the financial case here is more modest than in Pepco-served DC suburbs, it remains positive. Potomac Edison's lower electricity rate (~$0.14/kWh) extends payback periods compared to BGE or Pepco territory, but Maryland's state incentives apply fully, upfront installation costs are competitive, and EnergySage estimates average 25-year savings of around $37,000 for a typical Western Maryland system.

Hagerstown's mix of older downtown homes, mid-century ranches, and newer suburban development means roof assessments matter here. Many properties are excellent solar candidates — good sun exposure, minimal shading — but some older homes may need electrical panel upgrades before installation.

Fewer installers actively serve Western Maryland than the DC suburbs, so vetting Potomac Edison interconnection experience is especially important. Our guide identifies the companies with a confirmed track record here.

Common Questions

Frequently Asked Questions: Solar in Hagerstown, MD

Are solar panels worth it in Hagerstown MD? ▾

Yes, though the financial case is more modest than in Pepco or BGE territory. Potomac Edison's lower rate (~$0.14/kWh) means smaller annual bill savings, extending payback periods to 11–14 years. However, Maryland state incentives apply fully — SRECs, the MSAP grant up to $7,500, the sales tax exemption, and the 20-year property tax exemption. EnergySage estimates average 25-year savings of around $37,000 for a Western Maryland system. Solar still makes long-term financial sense in Hagerstown.

Why is the payback period longer in Hagerstown than other Maryland cities? ▾

Hagerstown is served by Potomac Edison at approximately $0.14/kWh — lower than Pepco (~$0.18–0.20/kWh) in Montgomery County or BGE (~$0.165/kWh) in Baltimore. Since solar savings come from offsetting grid electricity, a lower rate means smaller annual savings for the same system size. This extends payback to roughly 11–14 years versus 7–10 years in the DC suburbs. Long-term savings are still meaningful — roughly $37,000 over 25 years on average.

How does Potomac Edison net metering work in Hagerstown? ▾

Potomac Edison (a FirstEnergy subsidiary) provides net metering under Maryland law. Surplus solar exports are credited at the retail rate (~$0.14/kWh), with credits rolling over month to month until the annual true-up. Potomac Edison's interconnection process operates on FirstEnergy's systems and timelines, which differ from BGE and Pepco. Choosing an installer with confirmed Potomac Edison experience is the most important factor for a smooth, on-schedule project in Hagerstown.

Does Washington County offer a solar tax credit? ▾

Washington County does not currently offer a county-level solar property tax credit. Hagerstown homeowners rely entirely on Maryland's state incentive programs — MSAP grant, SRECs, sales tax exemption, and 20-year property tax exemption. While the incentive stack is less deep than in Montgomery or Howard County, Maryland's state programs still provide meaningful net cost reduction.

How long does solar installation take in Hagerstown MD? ▾

Physical installation takes 1–3 days. The full process from contract to activation — including design, Washington County permitting, inspection, and Potomac Edison interconnection — typically runs 8–16 weeks. Potomac Edison's interconnection review can run slightly longer than BGE or Pepco. Top installers manage all permits, utility coordination, and SREC registration on your behalf.
