Preliminary estimates only, not an engineering design or guaranteed output. Generation depends on location, season, shading, orientation, module temperature, inverter and system losses. Savings assume all generated electricity offsets grid purchases at the entered rate. Actual savings may be lower. Obtain a site survey and structural assessment before finalising a project.
