Is going solar actually worth it in NZ?

10/02/2025

Are solar panels worth it NZ?

If you’re considering solar for your home, you’re probably wondering - is it actually worth it? The reality is, with a premium solar system and a trusted installer, the return on investment is fantastic. With the right system, you:

  • Can slash your power bill
  • Increase your home’s value
  • Make money off your system by selling back to the grid
  • Have 24/7 backup power
  • Do your bit for the environment

Plus, with financing options like 0% interest on an $80,000 solar loan for up to 5 years, switching to solar has never been more affordable.


Mike Hosking recently talked about solar:

Why solar is a smart investment - the numbers stack up:

New Zealand’s power prices have skyrocketed over the previous 10 years and that trend is likely to continue. Installing solar lets you lock in your own free power source, protecting you from rising electricity prices. Plus, with NZ’s long sunshine hours (over 2,000 hours per year in most cities), there’s plenty of free sun power to harness.

A high-quality solar system offered by Harrisons Solar is built to last and deliver real savings. A Premium 5kW solar system starts from $11,500 and will generate on average 20KW per day, depending on your usage.

  • Check your power bill, how much are you paying per kWh? 26-27 cents per kWh?

Based on a typical install, solar costs as little as 12 cents per kWh over its lifetime - That’s serious savings.

Here’s an Example: This family reduces power bill from $200 a month down to $75 in the first year:

They have installed a 3.7kW Harrisons Solar Power System that has 10 premium AIKO high power solar panels with a top-quality Fronius inverter.

Their power bill has been slashed monthly - even more, as retail power prices continue to rise, they are saving $50,129 over the 25+ year performance life of the system.

Doing your bit for the environment:

This system is also equivalent to 97 trees planted or 47,701 km of car travel avoided. For details and assumptions click here.

Selling Excess Power Back to the Grid

One of the major benefits of solar is the ability to sell excess energy back to the grid. When your system produces more power than your home uses, the extra energy is exported, earning you credits on your power bill. This helps further offset your energy costs, making solar an even smarter investment.

Most retailers pay around 8-12 cents per kWh for exported solar power. However, with Harrisons Solar’s exclusive 18c buy-back rate, you can maximise your return—getting paid more for your extra energy than most standard plans offer. This means greater savings and a faster payback period on your solar investment.

A quality solar system will last longer and add 4.4% to your home value

Not all solar systems are created equal. Cheaper, low-quality panels and batteries come with dodgy warranties, unreliable performance, and even fire risks. Many budget panels promise 25-year warranties but fail within five years - leaving homeowners with costly repairs.

Harrisons Solar only installs the best-of-the-best, credible and award winning brands including Qcells, AIKO and Tesla, ensuring your investment pays off for decades and that there are no problems down the track - our recent research with homes.co.nz found that solar-installed homes sell for an average of 4.4% more - adding up to $35,000 in extra value.

What Kiwis are saying about whether solar panels are worth it in NZ:

Niknot - Waikato

"Met with Gareth and discussed our current and future needs, Gareth proposed a system, and we ultimately went with that. We could not be happier/impressed with the system often generating more than enough to run the house and charge the Powerwall, even on overcast and rainy days. The communication from Gareth and the admin team have been great, the install team were friendly and professional doing a great job all in one day. Highly recommend."

Lorraine & Les - Hawke's Bay

 "From beginning to start up the solar power journey has been a great experience! Initially we had a most informative session with Laura Duncan, Owner/Operator - Hawke’s Bay for Harrison’s Solar, who simplified the process and explained the benefits. We were convinced the system suggested would reduce our monthly power costs. Onsite the installers were professional, most efficient and happy to share. After installation Dave Duncan came to visit to check we were set up correctly with an App to follow on our phones and iPad. All questions were answered. We now feel knowledgeable and confident with daily evidence from meter readings we have made an excellent move to make savings when electricity prices are set to soar in the future. We enthusiastically recommend dealing with Laura and Dave Duncan if you want an efficient system and willing support when/if needed."
