Solar + Battery vs Solar Only

Estimate whether adding a battery to solar is likely to pay back from extra self-consumption and tariff shifting.

Worked example

If import costs 28p/kWh but export earns 15p/kWh, moving 1 kWh from export into later self-use is worth roughly the 13p gap before battery losses.

Frequently asked questions

Why separate solar and tariff shifting?

They are different sources of battery value.

Does this include backup power value?
