The right battery. Not the one you're quoted.
We check your quote against hundreds of real Australian quotes from trusted installers, and size the battery against your home's actual electricity consumption.
What people say about 
"Its super helpful to have a battery analysis based on my actual electricity usage (& factoring in for seasonality) rather than theoretical. Thank you!"
"The level of detail was excellent. An analysis of combined solar and a battery was invaluable."
"I was really happy with the analysis. It was well-considered, well-written and really helpful. It confirmed what I thought about our consumption patterns and a battery."
