Cool Stuff at Intersolar: How Many Roofs Do You Want on Your Building?

There are so many great ideas on display at the Intersolar show here in San Francisco that I couldn’t even attempt to list even a small fraction. But I came across a booth yesterday that I thought bore mentioning – a company called Galaxy Energy that, for $6.25 per Watt, sells an entire solar roofing system. Along with a 25-year guarantee (not bad for any roof), you can skip all the standard roofing material: the tiles, the slate, the singles, the subroof – all of it from the rafters up, and let these folks give you an attractive, beautifully engineered, weatherproof solution, where each mono-crystaline silicon panel (1.65 X. .99 meters) gives you 240 Watts.  What a terrific idea.

I laughed when I saw the simplicity and beauty of the idea. I told them, “Here’s a marketing concept you could explore: How many roofs do you want on your building?”

No extra charge.
