Calculation of Photovoltaic Cable Tray Dimensions
Calculate total cable cross-sectional area, divide by fill ratio (40% for power cables, 50% for control cables), then divide by desired tray height. Calculate cable tray fill ratio, weight loading, and derating factors for multi-standard compliance. This calculator determines if your tray meets industry standards (typically 30-50% fill for alternating single-layer or 40-50% for random arrangement). One of the big differences between domestic and commercial solar system design is the use of cable tray and in this presentation we will look at the use of cable tray on the roof of a large distribution warehouse that houses a commercial solar array.
