Estimate the annual AC electricity output of a UK solar photovoltaic system, in kWh, using the standard estimation method that MIS 3002 requires every MCS certified installer to use. The method is: annual output = kWp x Kk x SF, where Kk is read from the MCS irradiance dataset for the site's postcode zone, roof pitch and orientation, and SF is a shade factor between 0 and 1. Supply the postcode and the array's capacity in kWp, plus the roof's pitch in degrees from horizontal and its orientation in degrees away from due south in either direction, so that south is 0, south-east and south-west are both 45, east and west are both 90, and north is 180. The result carries the tabulated yield, the estimate, and what the same array would produce at the best pitch and orientation for that zone, so a roof that is merely good is not mistaken for a poor one. This covers the United Kingdom only; the dataset has no values for anywhere else. Method from MIS 3002. 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.
