This is called islanding and is essentially a safety barrier between your incoming supply and your fuse board. When there is a drop in voltage on the grid, solar batteries detect this and will automatically turn off the inverter and disconnect your battery from the grid as a safety precaution engineers will be working on electricity lines on the grid and if batteries are connected to it there is a risk of electrocution. Not all solar batteries enable you to use solar electricity during a power cut, so if this is a priority for you make sure you choose a battery which has this functionality. When a power cut strikes a store of this energy could be invaluable to your household.

Backup Power Supply: Some solar batteries will enable you to use your solar electricity when there is a power cut so you’re not left without power or lighting.

Energy bill savings: By storing energy during times of lower demand you can reduce the amount you need to buy from your energy supplier when energy usage is higher, saving you money on your energy bills.

The table below compares the key specifications of the best solar batteries available in the UK.įloor or wall-mounted (indoor or outdoor)įrom 5 years for 4.2kWh system, 10 years for 6kWh system Look out for models that will offer powercut backup as they will continue to work. Powercut backup: During a powercut, not all solar batteries will continue to supply your home with renewable solar energy. The more cycles that are warrantied, the longer the solar battery will remain above a certain storage capacity. Many solar battery manufactures offer warranties that guarantee a certain level of performance after a certain number of cycles. However, Lithium-ion batteries have a lower life-time cost and operate at a much higher efficiency level.Ĭycles warrantied: A solar battery cycle is the number of times it can be fully recharged from empty. Lead acid batteries are tried and tested technology that dates back over 100 years and they are cheaper in terms of upfront cost. There is still a strong and well established market for lead-acid batteries (the kind you’d find in your car) and they are still popular with many solar power users who live off grid. Technology: All of the solar batteries featured in this article are Lithium-ion based, this is the more progressive technology and the same battery technology you’ll find in your laptops, mobile phones and electric vehicles. Some solar batteries are stackable which means that over time you can add more units to your solar battery storage system to increase the capacity. The maximum capacity of the best solar batteries in our list is 20 kWh with the Powervault 3. In the UK, the average household uses around 8-10 kWh of electricity every day. And when you are comparing solar panel battery storage systems, there are a few things to look out for:Ĭapacity: This is the maximum amount of energy that can be stored within a solar battery at any time.

Solar battery storage technology allows you to use more of the free energy produced by the solar panels to save money and increase independence from the National Grid. This means that you’ll miss out on using the energy yourself and will have to rely on your energy supplier once the sun has set. Without a solar battery, this excess is delivered to the National Grid. Solar PV panels convert solar energy into usable electricity and, more often than not, they’re producing more electricity than can be used. What is a solar battery?Ī solar battery allows you to continue powering your home with renewable solar energy during the evening and at night when the solar panels aren’t able to generate energy.

Adding solar panel battery storage to your solar system will further reduce your reliance on an energy supplier, taking your energy savings even further. A solar battery allows you to use more of the energy being generated by your solar panels.
