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."

Things people ask.
Drop your quote into the quote checker. We will compare against 100s of other quotes and against our pricing for 100s of batteries. Your first analysis is free and on the house; if you want to compare multiple quotes that is a paid service.
Your first quote is free and on the house. We can analyse multiple quotes side by side and compare them for you — this service costs $39. If you would like a full analysis of your electricity consumption and see which battery is perfect for your home, that service costs only $19 more, so $58 in total.
It's easier than that! We are able to remotely read your energy consumption history through your electricity provider, who sends us everything we need to make the calculations. The connection is safe, secure, and regulated by the federal government with banking-grade security.
Our battery analysis tool is able to simulate solar systems on your roof based on a recent quote or a hypothetical system you haven't installed yet.
We are 100% independent. We are not owned by an energy company, and we do not sell your details to installers like quote websites do. By charging upfront for our services we can work 100% on your behalf, which allows us to give true independent advice and recommendations.
We analyse thousands of data points for each individual home, using industry-leading machine learning models and AI tools to build a simulation tailored to your property.
