Necessary to evolve solar mounting for large-size panels | Art Sign

 Solar racking manufacturers have had the seemingly unending task of keeping their solar panel mounting systems compatible with the latest iteration of PV module. While large-format modules are already being used in ground mount and some flat commercial rooftop projects, installers are inquiring about solar racking systems adapted to newer panel dimensions for residential applications, too.

The panel has always come before the solar racking, and it’s been up to manufacturers to play catch up. Previously, a typical 60- or 72-cell module would run between 65 and 74 in. long and 39 or 40 in. wide, respectively. Silicon wafer sizes have leaped from 125 mm to 210 mm in the last dozen years, with modules like Canadian Solar’s HiKu series now reaching more than 90 in. lengthwise.

As panels integrate newer wafer sizes and layouts, the increased module sizes might not necessarily affect the number of penetrations in a rooftop project, but it will require greater consideration for panel clamps. Snow load and downward pressure aren’t as much of an issue as wind and uplift.

As solar panels increase wattage and size, there will need to be new structural codes to advise system design, and racking manufacturers will try to keep up.
