Annual kWh Generation

This is the amount of electricity your PV power system will generate in a year. This value depends on each of the top four elements selected in the Income Calculator - solar array size, array orientation, array slope to the horizontal and overshading factor.

The annual kWh generation figure is calculated using the SAP (Standard Average Performance) calculation method used by all accredited Microgeneration Certification Scheme (MCS) installers such as ourselves.
