How this Washington solar cost calculator works

This calculator sizes a solar system from your electricity use. Your monthly bill, divided by the average District of Columbia electricity price, gives your yearly use; District of Columbia's sunshine (1,391 kWh per kW of panels a year) then gives the system size that covers it, adjusted for roof direction and shade. The installed price is that size multiplied by the price per watt homeowners in District of Columbia pay installers. Payback compares that price with what the panels save at District of Columbia power prices, assuming prices rise 3% a year.

District of Columbia numbers this calculator uses

Installed price
$2.63–$3.56 per watt in District of Columbia (typical $3.10), before rebates. A typical 6 kW home system costs $15,800–$21,400.
Sunshine
1,391 kWh of electricity per kW of panels a year in District of Columbia.
Electricity price
About 24.7¢ per kWh, the average residential price in District of Columbia.
Selling power back
Full retail net metering: power you send to the grid earns a credit at about the price you pay for it.
Rebates and tax credits
The 30% federal tax credit for buying solar ended for systems installed after December 31, 2025. Leases and power purchase agreements can still carry a federal credit through the installer for systems in service by the end of 2027.

An estimate, not a quote. Roof size and pitch, shading, equipment, permits and the installer all change the final price; installers confirm it after a site visit. Sources: EnergySage state installed-cost data (2026), NREL PVWatts, U.S. Energy Information Administration residential prices (2026), state program pages.

Frequently asked questions

8 questions
Are solar panels worth it in District of Columbia?
With electricity at 24.7 cents per kWh and full retail net metering, solar panels can be financially beneficial, especially with high usage.
How many solar panels do I need for my home?
A typical 6 kW system requires about 15-20 panels, depending on panel wattage and roof conditions.
What is the payback time for solar panels in DC?
Payback varies by usage and costs but often ranges from 7 to 12 years, considering current electricity prices and net metering.
Can I sell power back to the grid in DC?
Yes, full retail net metering allows you to earn credits at the same rate you pay for electricity.
What tax credits are available for solar in 2026?
The 30% federal tax credit ended for purchases after 2025, but leases and PPAs may still qualify through 2027.
How does roof direction affect solar output?
South-facing roofs are optimal. East or west-facing roofs need about 15% more panels. North-facing roofs are usually not suitable.
How does charging an electric car affect solar needs?
Each electric car adds about 2,700 kWh of annual electricity use, increasing the required solar system size.
Does shade impact solar panel efficiency?
Yes, heavy shade significantly reduces solar output, requiring more panels to meet energy needs.
