EVs, Batteries
and Power

How it actually works, with the numbers.

Independent write-ups on solar generation, home battery storage, EV charging and half hourly pricing, with the numbers behind them.


What This Site Covers

Econotion covers electric vehicles, home battery storage and household power. We look at how solar generation, battery scheduling, EV charging and vehicle to grid behave on half hourly tariffs, and we publish the numbers behind it.

How It Works

How the numbers on this site are worked out.
1. Use the Savings Calculator
Enter your postcode, annual energy bill, property type and whether you have an EV or V2G car. We calculate a personalised savings estimate based on real Agile pricing data and your specific property characteristics.
2. Get Independent Advice
The results show which improvements make financial sense for a home like yours — solar, battery, heat pump, insulation, tariff switch. Every recommendation includes real payback periods.
3. Understand the Numbers
The long-run cost comparison uses your actual figures rather than industry averages, so you can see which changes pay for themselves and which do not. Battery scheduling, V2G scheduling and tariff switching are all covered.
