Determine the average yearly electricity generation capability (i.e. energy yield) of your particular photovoltaic (PV) system by filling in the grey boxes below. Click on the red button for the result.

The estimate is based on historical solar irradiance figures from 18 NIWA climate zones. System losses due to panel soiling (3%), cabling (best practice), inverter inefficiencies (6%), temperature correction (varies according to AS4509.2) and module mismatch (2%) are applied.
