“Like a lot of people, we're spending more time at home since the beginning of the pandemic. The lights are always on and we're using more power running laptops, phone chargers, the TV and air-conditioning during the day when we would have previously been in the office. Aside from the increase in our family’s power bill, the impact on the environment was also a concern for us and we’ve wanted to get solar for a while.

"The 0.99% p.a. interest rate takes away the opportunity cost of going solar. And when you remove that initial outlay and compare repayments against the reduction in energy costs, it's a net positive cash flow with a very short payback period, well within the 10 year term. Basically, it's a no-brainer and the responsible thing to do from both an environmental and financial perspective."

“I have a family of five, a pool and air-conditioning, so our bills are always embarrassingly high. We’ve been thinking about solar for a few years now, but the upfront costs always put me off. When I heard about the Green Loan, a 10-year fixed rate at 0.99% p.a. with no early repayment costs, I thought, 'what’s not to like?'

"In the end it was a win-win situation. It ticked a box for me, as I was looking at installing solar anyway, and we all have a role to play in addressing climate change. I’m no expert, but I do know that finite resources, by definition, eventually run out.”
