"When you look at how much people are paying now, and the fact grid electricity keeps going up, it’s very hard to argue a solar installation isn’t economic.”
Rewiring Aotearoa's CEO Mike Casey talks to The Press' Blayne Slabbert about the benefits, costs and considerations of getting solar and it's a thorough rundown for anyone thinking about investing.
As he says, a typical household should expect to pay about $2000 per kilowatt for a fully installed solar system, including GST.
“The average system size in New Zealand has been around six or seven kilowatts,” he said.
Zac Le Heux, co-founder of Garden City Solar, says his "rough payback guide is six to eight years for solar only, assuming the family can use a good chunk of the solar power in the middle of the day.
“If you add a battery you’re more in that 10 to 12 year range,” he said.
If you've got solar, the best option is to use as much of it as possible to avoid high grid prices, but being paid to export energy is a nice cherry on top. It means many New Zealanders end up getting paid by their power company and shorten the payback period of their systems. Regulatory changes that meant customers would be paid more for exporting at peak times were meant to make batteries more appealing to customers and reduce the need for more investment in expensive poles and wires, but, as Marc Daalder writes in Newsroom, some retailers are not passing on the full value of those exports.
