We have 11 panels with 5 kW converter. We got $500 credit last quarter. It generated $1000 worth of credit but the power bill was $500 so we got 500 returned as cash. I didn't know you had to declare it as income for tax purposes though? No one ever told us that.

We get .4c 5 feed in tariff plus .10c from elec company.

We were told to use your electrical goods, dryer etc at night to maximize solar panels. Hubby explained it to me but it went in one ear out the other. So can't help with the why of it. Hehe.
