SolarRoofs.com recently introduced a new line of solar water heating collectors and systems. Called the Fireball 10-01, these 10 square foot collectors weigh only 19 pounds! Despite their small footprint and light weight they generate the energy equal to a 500 Watt solar Electric "PV" system, at a fraction of the price. The collectors are made from high performance copper absorbers and double wall polycarbonate glazing. Because of their low weight they can ship by UPS or FedEx ground and feature patented "Disappearing Headers" for damage free shipping. SolarRoofs.com refers to the 10-01 as "convenient building blocks to power and energy independence" These "Handy Sized" collectors are ideal for residential, RV and marine applications and can be matched with a PV system for increasing overall solar energy system performance.
