420W Solar Panel Large PV Module for Solar Arrays

At 420W this is a large-format module, made for arrays that are planned in kilowatts and mounted by a crew rather than one person on a ladder. Installers pair panels of this size with hybrid inverters on farms, commercial roofs and institutional buildings.

Because the module is physically big, mounting design does most of the work: use rails or a frame rated for the wind at the site, keep fixings to the frame rather than the laminate, and leave a gap for air to move behind the panel. Plan string voltages around the inverter's own limits before ordering quantities.
