Fletcher Building is turning to solar power for around a third of the electricity it needs to run its Laminex plant in Hamilton in a deal that will see the factory building's owners install a

Greg Visser is chief executive at Infratec, which also offers commercial solar installations. He said it was possible to deliver electricity at between 9 cents and 15 cents per kilowatt-hour from solar, compared with around 10 to 11 cents for industrial users on time-of-use bulk contracts and closer to 20 cents per kWh for smaller scale commercial electricity consumers.
However, firms were often investing not only for the current solar price but for the certainty of a locked-in tariff that could run for between 10 and 30 years, and for other corporate goals, such as carbon emissions reductions.

"We've managed to structure a power purchase agreement in which we pay per kWh, essentially recovering fixed costs invested by the landlord for a period," said a Fletcher spokeswoman. "But this wasn't a decision based only on costs – it's part of our drive to reduce carbon emissions across the Fletcher Building group."

Powersmart's chief operating officer Colin Daly said it was time for commercial property owners to consider whether "large, unobstructed roof space" would make sense for solar investment.
Other industry experts warned that numerous factors needed to be considered in whether or not solar was a good option, including where ownership of the solar equipment sat, the roof angle and exposure to extended sunlight hours, and the ability of an existing roof to take the weight of a solar array without costly strengthening.
