This is a screenshot from the AER PDF on the solar sharer program, which you can find here https://www.aer.gov.au/system/files/2026-05/AER - Solar Sharer Offer fact sheet - DMO 8 final determination.pdf

I’m in Queensland, so the Energex rates apply. The base tariff rate is 26c until 11am, then free for 3 hours. Then 8c for 2 hours and then 49c between 4 and 9pm. My memory was off, and it’s only double the rate, but my point still stands. The peak time is a lot more expensive on the solar sharer plan, so you need to do the maths and make sure your usage will be shifted towards the free period and away from the peak, because if your highest usage is in the peak period and you don’t mitigate that, you could end up paying more on the solar sharer plan. You can absolutely save money on the SSO, and we use it for that reason, but you can also end up out of pocket.
You’re not giving it away. You still get a feed in rate. And if you installed a battery at the same time, you can avoid the peak charges that kick in after the solar peak has passed.
