Akeena’s Flat Roof Solar System [Video]
By Dave | Edit
Eric Bowman describes Akeena’s flat panel system that does not need roof penetrations on a flat roof.
This is my 2nd video interview with Eric Bowman Regional Sales Manager of Akeena Solar out of Denver Colorado.
SolarDave: How does your flat roof system work?
Eric Bowman: The flat roof system for Andalay are developed for roofs that are typically on commercial entities so that have a membrane to them so it is kind of delicate so most folks that own a company or down in downtown Denver you will see some garages that have flat roofs and a membrane roof.
What we have done is come come up with a system that is ballasted meaning it has weights that go on the bottom of a framework so it is designed specifically for the Andalay system. The panels are integrated in to this framework and it sits on top of the roof and it weights can handle wind loads of over 150mph and does not need penetrations that need to go through the roof, it literally sits there. It can either go on the gravel or the membrane without any negative effect on the roof.
SolarDave: Is the thin film or is it a standard panel?
Eric Bowman:No this is a standard panel – Andalay panel. What we have done when you think about the weight of a solar panel and the Andalay module runs 45 pounds so you are going to divide that by the surface area of the panel so that 15 sq ft so you are only at about 3ibs per sq ft. which is a negligible amount of most residential and commercial structures.
So now we have ingrated that in to a frame work – with a picture that speaks a 1,000 words you can how that looks but embedded within that are our weights that fit in the bottom of this framework so it looks like a trianglar setup – flat bottom – 10 degree angle that is built in to that 10 degree angle and the weights help keep it from coming off the roof and meets all the juristical requirements without holes in the roof.
