The answer is – it doesn’t really matter – if you are using a Fafco Revolution 500 series Domestic Solar Water Heating System. These featherweight panels are just 8 pounds each empty, and 22 pounds filled. The additional dead load imposed on your roof is totally inconsequential.
A traditional 40 square foot glass/copper solar collector system weighs over 180 pounds when filled!
The pictured collector system is a 96 square foot Fafco Revolution system with four 2’x12′ solar panels, a photovoltaic panel for circulation, and an expansion tank. This low profile system is mounted on the roof and UV rated cross-linked polyethylene tubing (similar to PEX) is run to an integrated circulation module located next to your hot water tank. The system is simple – and simply amazing!
Where can I buy the Fafco Revolution 500 Solar Water Heating System?
Phoenix, AZ
Dale,
I’m sorry, but I don’t work for the manufacturer. I work for a dealer in Florida. You will need to call the corporate office at (800) 994-7652 if you are unable to locate a dealer using the dealer locator at: http://fafco.com/find_dealer/
All the best,
Jason
