Our guide to going solar in 2024


We’ve helped thousands of Kiwis reap the benefits of home solar over the past few years - in 2024, it’s your turn!

A home solar energy system will help you reduce your carbon footprint, gain energy independence, and enjoy some massive long-term financial wins. Our solar experts have put together this handy guide on the hows and whys of going solar in 2024.

How solar power works

Solar panels (PV panels) contain photovoltaic cells that absorb sunlight and convert it into energy. The energy is then passed through an inverter, which converts it into electricity that can be used to power homes, businesses, or be fed into the grid. High quality solar panels will produce electricity even in winter and on overcast days.

The actual costs and long-term savings

Given that the cost of solar panels has decreased by more than 80% in the past 20 years, it has never been more affordable to go solar. 

Solar installations have become progressively cheaper, because solar panel technology has become more powerful. If you install a system that matches your home’s current energy needs, it will cost roughly equivalent to 7-9 years of electricity bills. After this ‘payback period’, you’ll essentially be only using ‘free’ power.

Here’s an example of the net financial impact of a Harrisons Solar installation on a Kiwi home.

How installation works

The size of the team who comes to install your solar panels will partly depend on the size of your system but it will usually include our expert electrician and their solar panel installer. Most fittings can be completed in a day or two, and all you need to do on the day is make sure that the team can have safe access to all the areas involved in installing the panels such as gardens, paths, loft, roof, switchboard as well as electricity supply. Read up on our full installation process here.

Why early 2024 is the most advantageous time to go solar

1. The technology is better than ever. After years of research and testing, Harrisons exclusively partner with Qcells, the #1 premium solar brand in all key global markets. Qcells offer the most robust 25 year build and performance warranty in the industry, and their panels are incredibly high-performing. Check out their brand new panel using the latest in solar tech: the QTron! Also, solar batteries are now extremely efficient and accessible. Learn about how batteries are making solar power more affordable than ever here.

2. New Zealand household energy bills have steadily increased by 3% per year in recent years, and are set to double by 2028, whereas the price of a solar energy system will likely decrease. So, the average payback period will only continue to shorten over the coming years!. Why not start saving now?

3. 2023 saw a series of extreme weather events hit New Zealand, causing mass power outages. With climate scientists predicting that such events will increase in frequency in the coming years, independence from the grid has never seemed more attractive! Here’s how solar panels and batteries can help you weather any storm.
