SunMaxx Solar Introduces Ballast Tray System


SunMaxx Solar, a manufacturer of solar thermal systems and components, has released a ballast tray system that can be used to mount flat plates, evacuated tubes or photovoltaic collectors to a flat roof without any penetrations to the roofing membrane.

The ballast trays distribute weight over a large surface area, providing for a low roof load per square foot, the company says. Aluminum and stainless steel components are rust-resistant to provide years of maintenance-free service. Additionally, EPDM rubber pads on the bottom of the system increase friction and prevent roof surface abrasion.

The trays hold standard 8′ x 16' x 1-7/8â�³ size blocks. One tray can hold nine blocks weighing 15 lbs. each for a total of 147 lbs. per tray, SunMaxx Solar explains. Two SunMaxx TitanPower SU2 or 2.4 flat plate collectors can have up to four trays attached for a total of 588 lbs. between the two collectors.
