Solar savings calculator

Get a quick estimate of the system size and yearly savings for your Kempsey or Mid North Coast home.

Estimate only, we'll confirm with a free quote. Assumptions: generation of 1,200–1,330 kWh per kW per year (PVGIS data for Kempsey and the Mid North Coast, allowing for east/west roofs, shading and panel ageing; your suburb does not change the estimate); usage worked out from your bill at a blended 40.9c/kWh with a $1.98/day supply charge, from a real Kempsey-area Essential Energy time-of-use bill; feed-in tariff of 3–5c/kWh; without a battery, up to 40% of solar is used in the home, limited by your daytime use; with a battery, extra evening use is covered and total self-supply is capped at 80% of usage; time-of-use tariff, single phase, no controlled load or concessions, and no future price rises. Systems are sized from SKS packages up to 10.23 kW and batteries up to 25 kWh. Export on Essential Energy single-phase homes is limited (typically 5 kW); the estimate does not model export limits. Larger or three-phase homes are sized on site.
