NOOOO Dont do that, Never do that. The Law will change on July the 1st 2028 and if i'm still alive I will do What I have too.
If you’ve got a large system on the premium FIT you’d be stupid to give it up. Like I said my system was only 1.5kw which is basically useless and you can’t upgrade it without forfeiting the premium FIT.
My new 8kw system will save me more money than the old system ever would have, even exporting at 8 cents per kWh.
Assuming 100% efficiency from the old system from 7am to 1pm (they were north facing panels with the same shade issues my new north facing panels have) and 100% export (impossible) the most I could have exported was 9kWh. 9kWh x 48 cents FIT = $4.32.
The most I could have made from the old system on premium FIT is $388.80 per quarter. My power bills were between $500 to $800 per quarter so even if I was exporting 100% of my 1.5kw to the premium FIT (impossible to achieve) I would still have a bill of about $100 to $400 per quarter.
The new system is generating 2kw at 7am and over 6kw from 10am to midday and with load shifting to maximise self consumption has been calculated to put me in credit each quarter.
