Spearheading the Solar Century

Fairtide’s managing partners haven’t just harnessed the exponential growth of solar energy—they’ve helped bring it about. As industry leaders and innovators, they have created the financial tools, shaped the public policies, and scaled the solar companies that make these strategies possible.

Fairtide’s History

In the days of sail, commerce flowed faster and ships traversed coastal waters more safely by catching favorable tides. Nowhere was this more important than between Boston and New York, where geography and tide conspire to create powerful and complex currents.

That was until Captain George W. Eldridge developed his tidal guide to make sure mariners caught a “fair tide.” In honor of this scientific innovation, Elderidge named his home Fairtide. A century later, Nat Kreamer would spend his childhood at Fairtide.

Elderidge’s pioneering and innovative example is alive today in Nat Kreamer and Tom Foody’s work. Partners since 2011, Nat and Tom launched Fairtide to harness favorable conditions, build sustainable investment strategies, and maximize economic returns to investors.

Pioneering Product

Only about 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.
