Thinking of being more energy-efficient in your home? Go Solar. A solar panel is a renewable energy source that gets its power from the sun. And for this guide, we’ve outlined the best solar panels in New Zealand so you know which ones to get!
There are many solar panels out there offered by prestigious brands, you see. If you’re not too well-versed on solar panel tech, how do you know which of them you really need?
To answer this question, we will first guide you through the basics of what to look for in a solar panel. Since buying solar panels is a pretty huge decision, hopefully, we can shed light on this subject to help you decide.
Once we have gone through that, we will round up the best solar panels in New Zealand! So if you’re ready, let’s begin!
What to Look for When Buying a Solar Panel
There are 5 main things you need to consider before deciding to get a solar panel:
There are three main types of solar power systems to start off with. Let’s enumerate them one by one.
> Grid-Connected Solar: As the name suggests, this solar panel type works in coordination with New Zealand’s power grid.
When your solar panel produces excess energy, it directs it back to the grid. This cancels out your power costs.
> Off-Grid Solar: As opposed to the grid-connected solar type, off-grid solar panels only require batteries to work and are independent of the national grid. This is an excellent choice for rural or remote locations.
> Hybrid Solar: This is basically a combination of the two previous types we’ve mentioned (grid-connected and off-grid). You’ll have constant solar energy in your home or office, as it can be powered either by the grid or battery.
Solar panels generally last for 20 years or longer, so it makes sense that you should find a warranty equal to that number. Or if not, at least you should get a solar power system with a 10-year warranty.
Mind you, it can save a lot of headaches if you’ve installed the solar panels correctly, and in a position that’s protected from cricket balls, storms or accidents as much as possible.
A standard solar panel size for your home is 3kW (composing of 10 300W panels). This costs approximately between $8,000 and $10,000, which is an investment that needs to be carefully considered on your part.
Therefore, we recommend getting at least 3 quotes to have some options. This can also help you get the best deal in relation to the company and their services.
4) Payback Period
The payback period refers to how long it takes for you to recoup your investment in terms of energy use savings within a given period. It depends largely on what you are already paying for your electricity use.
When setting up your solar panels, it helps to make sure no obstruction gets in the way. Obstructions includes shades, trees, or coverings that may reduce your panels’ access to direct light.
The best times for your solar panels to get and convert energy is when the sun is at its zenith, usually from 11am to 3 pm. So, make sure that nothing’s getting between them and the sun at these times.
The Best Solar Panels in New Zealand
With the fundamentals in mind, allow us to list down the top-of-the-line solar panels in New Zealand today!
1) REC TwinPeak 300-330W Solar Panel
Best Overall Solar Panel
REC is a Norwegian brand that is respected for its product quality and innovation. It manufactures and supplies a premium range of solar solutions to provide cleaner energy.
The REC TwinPeak has half-cut cells with a lower resistance to generate power. Unlike other brands, it remains operational even when its other half has been left in the shade.
It features PERC (Passivated Emitter and Rear Cell) housed within the panel. What it does is reflect the captured light onto the cells above to maximise the power output.
At the back, there is a split junction box divided into 3 parts. This allows it to diffuse the solar power and convert it into electricity for your home or workplace.
Also, since an REC panel packs more power per square metre, you will need less in your home or office to achieve the equivalent output. Hence, this lowers the overall costs you’ll have to settle.
And finally, you will be given an exceptional 25 years of product and performance warranty for peace of mind and assurance.
- Half cut cells that work even with partial shading
- Quality Norwegian brand
- PERC system for higher utility savings
- Lower costs for the same amount of heating
- 25 years of product and performance warranty
2) Winaico 310W Solar Panel
Best for Limited Roof Spaces
If your roof has a smaller available space for solar panel installation, why not try out the Winaico 310W Solar Panel? It is made with the highest levels of quality in the semiconductor factory in Taiwan.
It has absolute efficiency thanks to its PERC system, where it captures and converts the radiation from the sun into power and electricity.
Neither cloudy skies nor shades can stop the PV cells from working. It performs remarkably well under those low-light conditions!
The panel’s dimensions are 1665 x 999 x 40 mm and weighs at just 19.6 kg. And it is engineered with fire safety properties, so as to keep your home safe at all times.
Likewise, the cells can fare like normal in the harsh heat or ever-changing weather in New Zealand. As a result, you will be able to save up on your bills when you can.
And while the Winaico solar panel has a high durability, you are kept out of worries, just in case, with 25 years of performance guarantee, and 15 years of product warranty.
- Performs incredibly in low-light conditions
- Has the PERC system for optimum efficiency
- Perfect for limited roof sizes

3) Longi Solar 300W Fixed Mono-Crystalline Solar Panel
Best for Boats, Campervans and Small Houses
Want to power up your boat or campervan with solar energy? Then look no further than Longi Solar’s 300W Monocrystalline Solar Panel.
Its monocrystalline structure makes it extremely capable of A-grade efficiency. It is more effective than its polycrystalline counterpart, which doesn’t properly diffuse the solar energy.
This makes it function without problems in dim-weather environments. In fact, you will be blown away by its capacity to give you renewable solar power while keeping your bills down.
Made of aluminium, it can endure the worst of the seasons. For instance, it can withstand whipping wind and heavy snow — that makes a bold statement about its durability.
Not to mention, its junction box is IP67 waterproof, making it rain- and dust-resistant. This tells you how it’s perfect for marine applications, where you’re going to benefit from the power of the sun.
And again, of course, you are covered by a 10-year product warranty (if there are any defects whatsoever) for home installations, but only 5 years for boats or campervans.
- Fantastic in low-light conditions
- Perfect for campervans, boats, and small houses
