A guide to kit locations
This guide helps you figure out the best place for us to install your solar battery and inverter. There are some limitations on where we can install this kit, so please read this carefully before making a decision.
Battery and inverter size
Your battery and inverter need to be installed near each other. Typically, combined they'll take up 1.5sqm of space on the wall, and protrude at most around 0.4m. For the exact dimensions of your kit, check the table below.
Battery: we'll always floor-mount your battery (except in very rare loft gable end wall installations).
Inverter: we'll always wall-mount your inverter, below eye level.

Locations
Best kit locations
The best location for your kit is either a garage attached to your house, or on an external wall of your house. 80% of our installs are in these two locations, and we strongly recommend them as the best options. We'll consider alternatives, but only if it's impossible to make one of these two work.
A garage attached to your house
This is the best overall option, as long as the walls are solid brick and in good condition.
An external wall of your house
This is a good location. The only considerations are that we need to install more than 30cm from a water source (like an outside tap), and that we need to floor-mount the battery on a hard surface. If you've got grass or pebbles, you'll need to put a concrete slab in place before the install.
Alternative locations
We can look at these options if necessary, but we strongly recommend considering the preferred locations first. These installations will come with extra complexity and often additional costs.
Utility room
Typically there isn't enough space in a utility room. If there is, we might be able to install here but there will be an additional £200 charge to install a fire alarm – this is a regulatory requirement.
Loft gable end wall
The 'gable end wall' is the triangular wall supporting the roof in your loft. In special circumstances we can wall-mount your battery and inverter here, but the wall must be fireproof – it can't be made of breezeblocks or wooden boards, for example. There would be an additional £200 charge for fire alarms in this location too.
Garage not attached to the house
You'll need to arrange trenching between the garage and your property for the cabling to run between the kit and the house. Even if you already have electricity in the separate garage, this is unlikely to be sufficient for the extra power needs of the system.
