Nearly Half Our Power Could Come From Rooftop Solar Panels

If rooftop solar could account for half of the power production. Why is it taking so long for it to take off? What is preventing people?
A home under construction July 19, 2008 in Temecula, California, uses new solar technology developed by SunPower Corp that allows thinner solar wafers to be designed into the shingles. Bulky and obtrusive rack-mounted solar panels may be a thing of the past. Spurred by recent advances in technology, solar panel makers are scrambling to come up with neater and cleaner products that will overcome the aesthetic objections of home owners to traditional solar panels.

Shout it from the rooftops — America’s rooftop solar capacity could be double what scientists previously thought.

If Americans slapped solar panels on every flat, sunny rooftop in the country, the U.S. could satisfy nearly 40 percent of its total electricity demand from solar alone, according to a new study from the National Renewable Energy Laboratory.

Experts say the numbers reflect newer, better methods for calculating total solar potential.

“For figuring out technical solar potential, I think this is a very good study,” Mike Jacobs, senior energy analyst at the Union of Concerned Scientists, told The Huffington Post.

Researchers used sophisticated LiDAR technology to map the topography of 128 cities in the U.S. down to the square meter. Combining that data with estimates of solar capacity researchers were able to gauge the total rooftop space available for solar power production in the U.S.

Their findings estimate the “technical potential” of rooftop solar production in the U.S. to be 1,118 gigawatts of capacity, which amount to 39 percent of national electricity sales and is nearly double what previous studies estimated. The study also found that small buildings hold the greatest solar potential, accounting for 65 percent of potential rooftop solar capacity.
