The Million Solar Roofs program was a Department of Energy (DOE) initiative to promote solar energy. Ending in 2006 before meeting the target of one million solar roofs (it reached 377,000) the program was still successful at laying the ground work for the increased adoption of solar energy.

While this initiative may be over the DOE continues to promote solar energy. The DOE’s latest solar program is the SunShot Initiative. For more information please see the SunShot Initiative webpage.
