Home batteries
A battery moves energy in time. Its entire financial case is the spread between the price you avoid and the price you pay.
Where we stand
We intend to publish the cases where a battery is not worth it. On a flat-rate tariff with modest consumption, the honest answer is usually to change tariff first and revisit in a year.
The questions that actually decide it
Check these before you commit
- What is your cheap-rate to peak-rate spread today?
- How much of your usage falls in expensive hours?
- Is the warranty stated in years, cycles or throughput?
- Is the quoted capacity usable or nominal?
