Solar power buy-back rates are the price per unit at which energy retailers pay for excess/exported solar power from homes or businesses.
The buy-back price ranges between 7¢ to 17¢ per kWh for exported solar power. Up to 40¢ is offered for exported stored battery capacity. View the New Zealand solar buy-back price list below.
To find out how much the buy-back price will affect how much you save on electricity bills, try out our solar calculator.

Please note - you can only claim GST if you are GST registered and you will need to inform your energy retailer if you are.
Before switching your electricity retailer to a company that offers a better buy-back rate, please check with them what your price for using / importing power bill be. Some electricity retailers have been known to increase the power price for solar power system owners.
Tip: As soon as you decide on going solar and have figured out which energy retailer to switch to, make the switch asap, as it can cause delays in turning on the system once the solar panels have been installed.
When solar panels generate more power than what is needed in the home or business, and there are no batteries in the solar power system that can soak up the excess power, the solar power is then exported to the grid. Your chosen electricity retailer will have a set price (as above) at which they will pay for this solar power.
This will show up as a credit on your power bill, which is normally subtracted from the cost of buying regular grid power. If the solar buy-back credit piles up you may be able to be paid for the solar power solar, but not all energy retailers will do this, so best to ask them first.
A good buy-back price is more important for homes and businesses that plan on selling a good portion of their solar power to the grid. For example, a home that uses 50% of the solar power in its home and 50% of its power will be exported will need to focus on getting a good solar buy-back rate. If the home is able to use closer to 80% of the power generated then a good buy-back price won't matter as much.
Using our solar calculator, you can see how different buy-back prices would change the amount of savings achieved each year, and you'd be able to see the difference between rates of return.
