Washington, D.C.'s electricity prices average $0.13/kWh, just below the national average of $0.14/kWh.
The average cost of a 6kW (equivalent to saving over 100 trees a year) solar power system starts around $15,000 in Washington, D.C. after the Federal Investment Tax Credit, or ITC. That system would pay for itself through energy savings within 6-7.5 years. System life can span well over 25 years, and savings will improve with inflation.
In 2019, biomass and solar accounted for more than 85% of the Federal City's total net power generation. That year half of the power in the entire city came from rooftop solar. Over one third of D.C.'s current solar capacity was installed in 2016. That year the solar industry supported 100 DC-based installers. This may be related to the Renewable Portfolio Standard Expansion Amendment Act of 2016, which established DC's Solar for All Program. DC didn't even have a utility-scale solar facility until 2019, presumably because it didn't need one. DC also has arguably one of the most ambitious Renewable Portfolio Standards in the world, calling for 100% renewable power by 2032.
DC has been home to some of the most famous residential rooftop solar system in the world. Amid the 1979 Oil Crisis, President Jimmy Carter had a system of 38 solar thermal panels installed over the West Wing. The system went live on June 20 of that year. President Ronald Reagan had the solar array removed in 1986. In 1992 sixteen of the panels from this system were installed above the cafeteria of Unity College in Maine, with the remainder of panels on display around the world. The journey of these system components is detailed in the 2010 documentary "A Road Not Taken."
In 2003 President George W. Bush had a 9kW photovoltaic system installed on the roof of the central maintenance building. A solar thermal array was installed on that same rooftop, providing heated water for grounds maintenance. A third solar thermal system was installed on the roof of the White House pool cabana, heating water for the pool and spa.
In 2014 President Barack Obama oversaw completion of a 6.3kW photovoltaic system on the White House roof, which White House Usher James Doherty said was "the typical size for the average American house." Additionally a solar water heater system was installed above the Executive Residence.
Whatever your installation cost, affordable financing options abound for just about any type of solar power system. Upfront, or "cash" purchases generally lead to the greatest long-term return on investment. However, solar loans and leases/PPAs can empower you to finance a solar energy system with a much lower overhead.
When designing a solar power system, you can customize solar modules, inverters, mounting, and batteries to meet the needs of your house or small business. Often cost and performance need to be balanced. Consider that while the most efficient PV modules may come with the best warranty, they also cost the most. Often buying more, less efficient panels can get you the same power at a lower price. However, how much area do you have to use for the array? Depending on size constraints you may need those high-efficiency solar panels to meet your power demands. These are just a handful of the many factors in solar panel equipment selection.
