Ballast Tray System

ConnectMaxx Free Standing Mount HardwareThe SunMaxx Solar Ballast Tray System fits all major solar modules and provides a reliable and long-lasting method 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 lower roof load per square foot. Aluminum and stainless steel components are rust resistant to provide years of maintenance-free service. EPDM rubber pads on the bottom of the system increase friction and prevent roof surface abrasion. The trays hold standard 8 x 16 x 1-7/8″ size blocks, which you can source locally. With these blocks in place in the ballast tray system, you can safely anchor your solar collectors without compromising the roofing membrane. One tray can hold 9 blocks weighing 15 lbs. each for a total of 147 lbs. per tray. Two SunMaxx TitanPower SU2 or 2.4 flat plate collectors can have up to 4 trays attached for a total of 588 lbs. between the two collectors!
