Beyond the savings
Let’s look at the environment impact
Reducing your electricity bill is one thing. But there’s an environmental benefit too.
Our system stores 15 kWh of energy, expandable to 30 kWh. In normal use, it charges overnight and powers your home the following day. Over a year, that adds up to around 5,475 kWh supplied from overnight-stored energy with a 15 kWh system, or around 10,950 kWh with a 30 kWh system.
That’s electricity no longer bought during busier peak periods — and instead sourced overnight, when demand is lower and renewable generation is often stronger.

(From a 15 kWh system)
That’s the amount of electricity no longer bought during peak daytime periods — and instead purchased overnight and stored for later use.

By moving that electricity away from peak, gas-heavier periods, emissions are reduced by around 0.8 tonnes per year.

With expanded storage, even more peak-period electricity is replaced — reducing emissions by around 1.6 tonnes per year.
