Pioneering Product

Only ~40,000 homes installed solar in the first 40 years of the industry.1 Nat’s invention of the residential solar power purchase agreement enabled 1 million homes to go solar in the next decade.2 Today, more than 4.5 million American homes are run on the sun.3 Most of them use the power purchase agreements created and first sold by Nat.
