Battery Storage Systems
What Are Battery Energy Storage Systems?
Battery energy storage systems are systems that allow surplus solar energy to be stored and used later. This means that solar panels, which usually generate most energy during the day, can still provide energy to your home in the evening and at night.
Most energy storage batteries are lithium-ion, much like the batteries in mobile phones and electric cars. These batteries are lighter, more durable, and can store more energy per kg than lead-acid batteries. They are more efficient at storing energy, but come at a higher price point.
Advantages of Home Battery Storage
Storing surplus energy means that no energy is wasted, therefore you are getting the most value for money. It means that energy is more readily available during times of lower electricity generation, and you have the potential to generate additional income.
Firstly, when utilising battery energy storage systems, energy production is more consistent and more reliable for homes. When surplus energy can be stored, you won’t need to limit household energy usage on overcast days, or during the evening and at night. The solar energy that has been stored can be used to power your home as usual, and even charge your electric car.
Cheaper Energy Bills
Storing your generated energy is the best way to make sure you achieve the maximum saving on your energy bills. When you have surplus energy, storing it will mean you don’t need to rely on ‘back-up’ energy from the grid, and therefore will save a considerable amount of money on utility bills.
In addition to this, storing extra energy means you can earn money by selling it to the grid, if you don’t need to use it yourself. This income generation means that it will take fewer years to realise the financial benefit of installing solar panels.
Yes. Your solar panels will still work without home battery storage, UK. However, battery energy storage systems allow you to use much more of the green energy you generate. This energy would otherwise be wasted or sold to the grid.
Real Power can install reliable battery storage in your home, in order to help you maximise the efficiency of your solar panels and reduce your costs.
Lithium-ion batteries used in battery energy storage systems will need to be replaced every 5 to 15 years. This means you will probably need at least two throughout the lifespan of your solar panels, UK, which tend to last between 15 and 30 years.
The cost of installing a home battery storage system varies depends on the size of battery required. Typically, the system will cost between £1140 and £5700 in total.
A 3 to 4 kWh Lithium-Ion battery will cost approximately £3240, whereas a 9 to 13kWh Lithium-Ion battery will cost closer to £5700. 4 to 7 kWh batteries will start at £4070, and 7 to 9 kWh batteries will start at £4925.
All above pricing is subject to price fluctuations and therefore we recommend that you contact Real Power directly for a personalised quote.
Investing in home battery storage means you are not only investing in the long-term green energy production of your home, but also in the long-term renewable sources of energy for the whole country.
