My solar panels run during the day 44c/KWh ..................................into my account.
You export at 44c.......but take off any elect that you use....fridge, washing machine etc !
If you had a pool on tarriff 33...at 18c....you would theoretically export at 44c, but still pay 18c.
If you had a smart meter and ran the pool at night, you would export during the day at 44c ( of course minus whatever gets used during the day ), but only pay 11c during the night !
AGL in NSW now only offer 5.1c/kwh for feed in tarriff , so you would need a big system to 100% offset your power bill !!
