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."

No. We connect via CDR (Consumer Data Right), the bank-grade open-data framework. Your electricity provider hands us 12 months of interval data directly, no PDFs, no spreadsheets.
Battery analysis without solar still tells you whether time-of-use shifting alone pays off, and we can predict the solar performance for your roof if you're adding both together.
No. We don't sell batteries and we don't take commissions or kickbacks from installers. You pay us once, and that's our only revenue.
We use your half-hourly interval data, your tariff, your roof orientation (if solar), and a year of typical weather.
