Short answer
Solar in Spring Valley, DC typically means a larger rooftop or ground array on a single-family home, often paired with whole-home battery backup and an EV charger, and certified for DC SRECs. Spring Valley is one of eight Northwest neighborhoods averaging one housing unit per building.
The homes
One house per lot
Spring Valley is one of eight Northwest assessment neighborhoods that average one housing unit per building, all of them single-family homes, and more than 70 percent of homes in this part of the city are occupied by their owners.
Large homes use more power, and large roofs and lots give more room to make it. That usually means a bigger system than a rowhouse could carry, which DC's credits reward.
Backup
When a whole-home battery makes sense
Most DC owners choose essentials-only backup. In large homes with central air, well pumps or home offices, whole-home backup can be worth it, but it usually takes two or more batteries and careful attention to starting surges.
We size the batteries to the loads the house actually starts, and show you the runtime for both partial and whole-home designs before you decide.
How a job runs
Design, permits and credits
After the roof, yard, shade and panel check come the design, the DC building permit, the Pepco interconnection, installation, inspection and permission to operate. Then we certify the system for DC SRECs.
Larger systems sometimes need a service upgrade or a supply-side connection, which we plan and price with the solar rather than after it.
