'Batteries and Solar Power: Guidance for domestic and small commercial consumers'.

This new guide explains the types of battery storage on the market and how they fit with existing or new solar PV systems. It explains how much electricity a typical system will store and under what circumstances and the expected lifetime.

The guide goes on to explain what happens to battery storage systems in winter, when they might need to take charge from the grid, the different ways they can be connected to a solar PV system and whether they will work during a power cut.

Finally the guide contains a list of 20 questions which consumers should be sure to ask their battery storage installer before agreeing to the contract.
