The cash-strapped Whangarei SPCA is set to save thousands of dollars a year if it manages to become fully solar powered.
Manager Francine Shields said the addition of 18 solar panels would either eliminate the $1300 a month power bill or significantly reduce it.
While such an advanced system would usually cost upwards of $20,000, the SPCA only needed to raise just over $5000 for it, Ms Shields said.
Harrisons Energy Solutions offered to fund half the cost of installing the panels while a member of the public had pledged $6000 towards the project. Despite being in financial difficulty, becoming solar powered was a smart choice, Ms Shields said.
"I think it's an excellent decision to make," she said. "I am quite positive we can turn it around by decreasing our ongoing costs."
