Disclaimer: This capacity calculator provides preliminary boundaries to assist Solar Installers and Building Owners in determining the likely risk category of a proposed array before detailed design. It solves for the capacity limits corresponding to AS/NZS 1170 structural seismic/wind risk matrices. It does not replace a site-specific Solar Ready Certification.
