Solar Together

Solar Together London is a group buying scheme – Islington Council have been successfully participating in the scheme over the past few years. It brings together households and local government to get high quality solar panels at a highly competitive price. It aims to help you through the process, keeping you informed at every stage.

In addition, this year the scheme will include a battery storage option alongside your solar panel installation. Battery storage saves the unused energy that is generated by your solar panels, meaning that you can use it whenever you want, instead of only during the day. It can also reduce the electricity you use from the grid and further cut your energy bills. You can add this battery storage option to your installation when you receive your personal recommendation.

If you already have solar panels installed, you can maximise how much of your self-generated energy you can use at home by having battery storage – to register for this storage option, simply go to and select the ‘storage only’ registration button.

Registrations for Solar Together will close at 23:59 on 22nd March.
