solar Power in New Zealand: Dispelling Myths and Highlighting Benefits

One of the biggest misconceptions about solar power in New Zealand is the belief that it requires constant sunshine. Though, according to Rory McCarthy of Lightforce Solar, it’s actually about light, not heat. Ultraviolet light reaches solar panels even through cloud cover.New Zealand receives around 1500 hours of quality UV light annually – comparable to the United Arab Emirates’ 1630 hours, despite the Gulf nation boasting 340 days of sunshine.

Even on cloudy days, solar panels continue to generate energy, typically operating at 40% to 60% of their capacity.Northern European countries like Germany, Denmark, and Poland have successfully implemented large-scale solar plants despite experiencing similar or worse weather conditions than New Zealand.

“We’ve been late to the party, but in some ways, that’s not a bad thing,” mccarthy says. Currently, approximately 80% to 85% of residential solar systems installed in New Zealand include battery storage. This contrasts with earlier adopters like Australia, where many systems were initially installed without batteries, leading to voltage fluctuations on the grid.The Australian experience has contributed to some common misconceptions regarding solar’s potential.

McCarthy estimates that solar power can reduce electricity bills by 25% to 50% or more, with homeowners typically achieving payback on their investment within five to seven years.

The advantages of solar extend to businesses as well. “Using your own power on-site is a huge saving.You can plan for the future with power being a much more fixed cost, rather than an increasing variable impacting your business’s profitability,” he explains.

Agricultural operations are notably well-suited to solar energy. Pumping water for fields and livestock requires notable energy consumption. Unlike residential properties, farms aren’t limited by roof space. Solar systems can be installed on sheds, as ground mounts, or even in car parks for commercial sites. Lightforce Solar has completed installations on numerous farms,including one for Kevin Barrett,father of All Blacks Beauden and Scott Barrett.

“Most people think it’s just a solar panel, but it’s actually a complete system.” A full installation encompasses roofing structures, ducting, mounting systems, inverters to convert DC power to AC, and batteries requiring hybrid inverters to manage the flow of energy from panels, storage, and the grid.

“When you install a solar system, you are essentially turning your roof into a power station. So, you want to make sure you do it right.”
