However, if you do want to have a go at connecting your solar panels to a battery, it’s worth finding out whether your system is ‘storage ready’. Most relatively new systems will be, since batteries are becoming more commonplace. If your solar panels are storage ready, they will have an inverter that can easily have a battery added to it. If this is the case, then you should be able to buy the solar battery you want and follow the manufacturer's instructions to install it.

If you don’t get the solar battery connected properly and something goes wrong, it could cause a fire or you could electrocute yourself. If a fire breaks out due to your battery, it’s unlikely that your home insurance company would pay out since you connected the battery yourself. That’s why it’s always worth speaking to a registered installer to install a solar battery storage system for you.

• The Building Regulations Compliance Certificate - This is provided to confirm that the electrical works done complies with the Building regulations.
• The Electrical Installation Certificate (EIC), alternatively you can have a Minor Electrical Installation Works Certificate which is provided to confirm that the electrical works done satisfies the BS 7671.

In addition, the local building control body must be provided with a copy of these documents. In such an event whereby the electrical work was completed after 2013 and either it was done by yourself or by an individual who isn’t a registered professional, then there’s a need to make sure that work is inspected by a registered third party certifier within 5 days of completion.
