Technical FAQs 4

How long do solar panels last in New Zealand?

Modern solar panels in New Zealand have an energy payback period of just 0.7 to 1.6 years. With lifespans of 30 years or more, that’s decades of clean energy generation, far outweighing the emissions from manufacturing and shipping.

Do solar panels deteriorate faster in New Zealand?

If the Solar Panels are constantly exposed to very extreme weather conditions, they are likely to deteriorate faster. This is less of an issue in New Zealand, where heavy snowfall and extreme weather events in residential areas are relatively rare.

Are large-scale solar developments a good idea in New Zealand?

Large-scale solar developments are a relatively new development in New Zealand, and we can look to earlier adopters of solar (whether rooftop or utility-scale) for lessons on how to deal with long-term issues that can arise with this technology.

How long do solar panels last?

Their Performance 7 solar panels come with a 30-year warranty, offering a guaranteed peak power of 87.2% in the 30th year. Given the panels will still be performing at 87.2% of their max power output, you can expect them to last for decades beyond that. SunPower Maxeon panels are even more impressive, with a 40-year warranty.
