Thinking of being more energy-efficient in your home? Go Solar. A solar panel in NZ is a renewable energy source that gets its power from the sun. And for this guide, we’ve outlined the best solar panels in NZ New Zealand so you know which ones to get!
There are many solar panels in nz 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 good solar panel in NZ. 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 in NZ
There are 5 main things you need to consider before deciding to get a solar panel:
There are three main types of systems of solar power in NZ to start off with and one additional advanced Thermal Solar panel heating system. 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 in NZ 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.
> Thermal Solar: The Thermo Solar panel heating system heats your hot water directly and stores it in the storage cylinder which saves you up to 80% on your hot water costs over the year. The thermal solar panel system saves greatly on the PV solar power system and roof space.
The best solar panels in nz 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. Not only will this give you an idea of how much solar panels cost in NZ, but it 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 NZ New Zealand Reviewed
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. A good long warranty is one you need to look for when searching for the best solar panels in NZ.
