It then works out your export payments under the SEG scheme, based on your tariff, to project indicative SEG payments under these conditions.

How much energy does a solar PV system produce a year?

Solar electricity generation – 3,400 kWh per year (typical 4kWh solar PV system with average output of 850 kWh per year per kW of panel). Solar panel and battery storage costs based on typical prices available if both are installed together. A max power output of 5 kW and a max charging capacity of 3.68 kW is assumed for a 13.5 kWh storage battery.

How much solar energy do you use a year?

Your annual usage is a combination of grid purchases PLUS the solar generated electricity that was used in your home rather than being exported to the grid. As a guide, typically around 40% of the solar electricity generated by solar panels is used in the home and 60% exported to the grid.
