Convert a completed MCS sunpath shading assessment into a shade factor, using the procedure in MGD 005. The MCS sunpath chart is divided into 84 segments, each worth one per cent of the year's useful irradiance. An assessor stands at the middle of where the array will go, plots what blocks the horizon onto the chart, and counts the segments covered. This tool takes that count and returns 1 minus the loss, which is the SF term in the MIS 3002 output estimate. Objects within ten metres of the array are near shading and are assessed separately, from each affected part of the array, not from its middle. They can be listed here for the record, but MGD 005 is explicit that near shading has a considerable effect and should be avoided. This tool does not perform the assessment. It does the arithmetic on an assessment somebody made. Method from MGD 005. These calculators follow the published MCS methods, for understanding a system and checking a quotation. Anything that gets installed still needs a design and a site survey from a certified installer.
