Estimates are indicative only and are not a guarantee of actual output or savings. Generation varies according to location, weather, orientation, tilt, shading, temperature and other installation conditions. The calculation uses the rated panel capacity and the specified 800W microinverter characteristics of the relevant kits. Actual electricity savings also depend on how much of your solar generation is used on site and your electricity tariff.
