$0 sonnenFlat monthly fee for 24 months - How's that for bill shock!

Australia’s ever-increasing electricity prices have become the norm, with quarterly bills shock a real experience for many households. Switching energy retailers or contracts may give temporary relief when it comes to saving energy bills. Instead, households are increasingly installing rooftop solar and home batteries as an alternative to relying on power companies to supply expensive, grid electricity.

sonnenFlat is an energy plan from sonnen that combines home batteries with a rooftop solar system.

As the only energy storage company to deliver energy savings through a fixed monthly power bill, sonnen now offer new customers, $0 sonnenFlat monthly fee for the first 24 months when they purchase a sonnenBatterie (min 4 kWh)*. They will receive an upfront credit of at least $1,176 to cover their monthly fee for the first 24 months sonnenFlat and a $0 energy bill. Terms and conditions apply.
