Is solar worth it in Bethesda without DC's SRECs?

For many homes, yes, because Pepco credits exported solar at the full retail rate. The payback comes from the bill rather than the credits.

How big a system does a Bethesda house need?

It depends on usage. A 5 kW system makes about 6 MWh a year in Maryland; we size from your actual bills.

Can you add solar for a new EV?

Yes, either as a new system or an expansion, with a charger that uses daytime production.

Are there loans for solar in Bethesda?

The Montgomery County Green Bank offers low-interest solar loans, with 0 percent for the first 10 years in Equity Emphasis Areas.

Solar installers for Bethesda, MD homes

In Bethesda the numbers come from the electric bill, not the credit market. Maryland SRECs are worth a fraction of DC's, so a Bethesda system earns its keep by covering what the house uses. That puts sizing, batteries and EV charging at the center of the design.

Short answer

Solar in Bethesda, MD pays back mainly through Pepco's full retail net metering, which stays open to new Maryland customers until July 1, 2027, because Maryland SRECs are worth far less than DC's. A 5 kW system in Maryland produces about 6 MWh a year, so we size each system to the house's actual usage, including any EV.

Sizing

Matching the system to what the house uses

A 5 kW system in Maryland produces about 6 MWh a year. Whether that is too little or too much depends on the house: a home with an EV, a heat pump or a pool can use far more than that. We start from twelve months of Pepco bills and any changes you plan, then size the array to cover usage without exporting much more than the net metering credit can use.

Maryland's sales tax exemption on qualifying solar equipment and Montgomery County Green Bank loans help on the cost side.

Batteries and charging

Where a battery and an EV charger fit

With full retail net metering, a battery in Bethesda is for outages rather than savings. We size it to the circuits you want kept on. An EV charger set to charge in daylight uses solar directly, and a charger on a schedule still benefits from credits banked during the day.

If the panel is full, we look at load management before recommending a service upgrade.

What happens between the first call and turn-on

The first visit looks at the roof, the shade from Bethesda's mature trees and the main electrical panel. From there we design the system, file the county permit and the Pepco interconnection, install, pass inspection and wait for permission to operate.

We register the system for Maryland SRECs, set up monitoring and show you how to read production against what the design predicted.
