Get started with Harrisons Solar. They’ll design and install a quality solar system tailored to your home. Plus, with this offer — you can sell back any excess solar you generate for a big 18 cents per unit!

We buy back any excess solar you generate at our standard buy-back rate of 11.1 cents per kWh. Terms apply*
*Solar buy-back rates exclude GST and discounts. Residential and business terms and conditions apply.
Buy-back rates are dependent on line company charges. There are some networks such as Orion Network, where the buy-back rate will differ.

With solar panels you can turn sunlight into electricity. This electricity can be used in your home, stored in a battery, or exported back to the grid. This export can then be purchased by retailers like Mercury. This is known as “buy-back”, “distributed generation”, “import/export”, or “embedded generation”.
You must have written approval from your lines company, to be able to export power from your property onto their network. You can find your lines company contact details here.
The buy-back rates will be applied once your import/export meter is installed, and you begin exporting excess solar. It may take a few weeks for your meter to start communicating, however once it does you’ll be credited for any units you’ve exported back to the grid since your import/export meter has been installed.
This is a meter with two registers, one to record the import usage from the network and one to record the export usage to the network. These are also known as buy-back or 2-way meters.
In order for us to record your usage and output, you’ll need to get an import/export meter installed. Once installed, the meter installation fee will be added to your Mercury account. For regular capacity meters, the import/export installation fees are $195 for urban, $265 for rural and $325 for remote. If you require a higher capacity meter, the fee is quotable and we’ll let you know of the fee before installation.
If you suspect a fault with your solar system, follow the shutdown procedure instructions for your solar equipment, this will be noted next to your system.
After shutting down your system, get in touch with your installer for additional guidance. In an emergency, such as a potential fire risk, dial 111 for assistance.
If you're not GST registered, GST will not be applied to your solar generation.
If you're GST registered and your connection with us as a solar power generator is part of your business activity for GST purposes, please let us know on this form and we’ll get this applied to your account.
Once your GST number is applied to your account, the GST credit for your solar generation will be included in the total GST amount on your Bill. The GST credit is combined with GST charges for your overall electricity.
In the below example the GST on other charges is $37.95, then a credit of $5.39 for the GST on generation is applied, reducing the GST to $32.55.

If you're not GST registered, GST will not be applied to your solar generation.
If there is no meter read available, or if you didn't export any solar back to the grid in that billing period, the ‘Generation' line won't appear on your bill.
