🚨 2026 Auckland Market Update: > As of January 2026, Auckland homeowners are facing a new energy landscape. Following Vector’s 21% line charge increase and the ongoing phase-out of the “Low User” tariff, the average Auckland power bill has climbed significantly. Additionally, with major banks like ANZ and ASB now offering 1% (or interest-free) “Green Home Loans,” the ROI for solar in 2026 has shifted. This article has been updated to reflect these new costs and the latest smart-battery technology available at AVID Solar.
Adding a hot water diverter to your solar system is often the cheapest part of the system that has the most impact.
If you have already installed a solar panel system on your home, you may be wondering if there are any other ways to maximise the energy savings that you can achieve. One such option that you may want to consider is installing a solar diverter.
A solar diverter, also known as a hot water diverter, is a device that is designed to take excess energy that would otherwise be sent back to the grid and use it to heat your hot water cylinder. This means that instead of selling the excess energy back to the grid at a lower rate, you can use it to heat the water that you will be using in your home.
Adding a hot water diverter to your solar panel system is often the cheapest part of the system that has the most impact. By using the excess energy from your solar panels to heat your hot water cylinder, you can save a significant amount on your power bill. This is because heating water is one of the biggest energy expenses for most households.
The device learns when you regularly use hot water and has the option to ‘boost’ and instantly heat from the grid so there will be no cold showers if you have lots of people in the middle of winter. This means that you can still have hot water even when there is not enough energy being generated by your solar panels.

One of the biggest advantages of installing a solar diverter is that it can help you maximise the savings from your solar panel system. Solar energy is sold back to the grid for less than what we buy it for, so it makes sense to use as much of it in our homes as possible. By using the excess energy from your solar panels to heat your hot water cylinder, you can reduce the amount of energy that you need to buy from the grid, and thus reduce your power bills.
In addition, installing a hot water diverter is a relatively simple and inexpensive process. A professional solar installer like AVID Solar can easily add a hot water diverter to your existing solar panel system, and it typically only takes a few hours to complete.
In conclusion, adding a solar diverter to your solar panel system is a great way to maximise the energy savings that you can achieve. By using the excess energy from your solar panels to heat your hot water cylinder, you can reduce your power bills and make the most of your solar investment.
