Easily design accurate, roof-ready solar systems for residential and commercial projects with our intuitive tools. Quickly determine panel layout, equipment needs and system compatibility for any metal roofing application. Simplify rail-less system planning, confirm compatibility and generate a complete Bill of Materials.
S-5! calculators require roof-specific information, including roof slope, metal roof panel details, snow load and roof dimensions. The solar calculator also requires solar panel size, wind speed and certain ASCE 7–related inputs.
Yes, the calculator supports both residential and commercial metal roofs.
The calculator uses roof dimensions, panel sizes and system gaps to calculate optimal attachment spacing that maintains structural integrity.
Tests include normal-to-seam and parallel-to-seam conditions to simulate real-world conditions on metal roofs. Learn more about our testing here.
