TECHNOLOGIES >> BATTERY STORAGE
Battery Storage – Store Energy When You Need It Most
Energy storage using Battery Energy Storage Systems (BESS) allows you to capture surplus power generated through solar and wind systems and release it when needed. Modern battery systems can also export and import electricity directly to the grid, helping balance national supply and demand while providing opportunities for energy trading through battery communities and microgrids.
Is Battery Storage Right for You?
Battery storage is particularly beneficial for larger premises or higher energy demand users. It can often be installed in domestic settings and have a real impact on your bills too. We can help assess your investment by reviewing your annual usage, advising on generation capacity, suitable battery types, installation costs, and potential export payments.
Current UK Pricing (2025):
Solar battery costs in the UK currently sit between £2,500 to £10,000
A standard 4kWh battery costs on average £3,500 and has a lifespan of 10-15 years
0% VAT on solar storage batteries since February 2024, making prices up to 20% lower
Modern Battery Technology
Today’s battery storage systems use advanced lithium-ion technology, primarily Lithium Iron Phosphate (LiFePO4) chemistry, which offers:
Extended Lifespan: Cycle life from 2,500 to more than 9,000 cycles depending on the model
Enhanced Safety: LiFePO4 batteries provide enhanced safety, longer cycle life, and thermal stability compared to other lithium-ion chemistries
Improved Performance: Latest versions announced in 2023-2024 made significant improvements in energy density from 180 up to 205 Wh/kg without increasing production costs
Solar and Battery Integration
Solar PV systems in the UK have become increasingly popular, and battery storage now makes economic sense for most installations. Modern systems can significantly increase your solar energy utilisation.
How It Works:
- Daytime Generation: Solar panels generate electricity to meet your immediate power needs
- Battery Charging: Excess energy charges your battery storage system
- Grid Export: Once batteries are full, surplus energy feeds back to the grid
- Evening Use: When solar generation stops, your system draws stored energy from batteries
- Grid Backup: Only when batteries are depleted does the system import from the grid
For typical households, battery storage can increase solar energy self-consumption from around 50% to 85% or higher, depending on usage patterns and battery capacity.
