Users can fill the PV-Pod with varying volumes of water depending on the local wind-uplift resistance requirements. As a result, the surcharge load added to the roof by the photovoltaic panels' ballast can be optimized.
The PV-Pod is now commercially available for flat-roof installations. Optional interlocking braces can increase the wind load capacity of PV Pods.
Conventional ballast systems rely on concrete blocks, which can damage the roof membrane if dropped.
Weighing 23 pounds when empty, the PV-Pod is portable and designed to be carried on a person's shoulder.
