2. But what about poles and wires?
Some households are happy with a much smaller bill
It is still possible to be in credit with your energy supplier despite the drop in feed-in rate.
Some people are happy still paying a small reduced energy bill.
Others oversize their solar and battery system to a point where they comfortably cover all their energy needs and generate enough power to help counteract the daily supply charge.
Oversizing can sometimes help offset supply charges
A frequent way people look at doing this is to oversize their battery system and feed a percentage of their battery back to the grid at night that they do not need.
The amount you are paid for feeding energy back at night is far greater than what you are paid during the day.
- • This is completely optional
- • Different energy providers will have different incentives
- • Night feed-in value can be materially higher
- • Battery size and tariff structure both matter
Different providers offer different incentives
The value of export, storage, and VPP participation depends heavily on your retailer and tariff setup.
That is why the best system is not just about hardware size. It also needs to match how you actually use energy and what your provider offers.

Knowledge check
Can a household still end up in credit with lower daytime feed-in rates?
Yes. Some systems still end up in credit, while others simply shrink the bill dramatically and offset more of the supply charge.
Is feeding battery energy back to the grid at night required?
No. It is optional and depends on your retailer incentives, battery size, and whether that strategy suits your home.
