Callaghan solar questions

How much less does solar make in winter in Callaghan?

About 23 kWh a day from a 10 kW array in June, against about 58.7 kWh in January, on the same estimate as above. Your installer can size panels and any battery around the months that matter for your household.

Is there a limit on how much solar I can export in Callaghan?

Single-phase export limits in Callaghan are set by Ausgrid and are typically around 5 kW, but they vary by area and connection type and can change. Your installer confirms the exact limit for your address as part of the grid connection application.

Is the estimate a quote?

No. It is an indicative estimate from your postcode and power bill, and it leaves out purchase and installation costs. A real price needs an installer to check your roof and switchboard.
