Battery Energy Storage
Maximize Your Solar Investment
Solar UK is an MCS-registered company, providing complete solutions for solar PV systems, including design, supply, installation, and ongoing maintenance to keep your system performing at its best throughout its life.
Why Add Battery Storage?
If you have the space and budget, integrating a battery energy storage system is one of the smartest ways to optimize your solar PV setup. Battery storage:
-
Maximizes energy efficiency by storing excess solar power for later use
-
Provides flexibility for managing energy consumption
-
Improves performance and reduces reliance on the grid
Unlock Greater Benefits
In the right circumstances, battery storage allows you to:
-
Trade electricity with grid suppliers
-
Combine solar PV + battery + EV charging for a complete renewable energy solution

In today’s volatile energy market, UK businesses are increasingly adopting Battery Energy Storage Systems (BESS) to improve energy security, reduce costs, and boost operational efficiency.
BESS technology enables:
-
Load shifting – Store energy during low-cost periods and use it when prices peak
-
Peak shaving – Reduce demand charges by managing consumption intelligently
-
Integration with on-site renewable generation – Maximize solar PV and other green energy sources
By reducing reliance on the traditional grid and minimizing exposure to wholesale price fluctuations, battery storage systems help businesses optimize energy usage, support decarbonisation goals, and strengthen sustainability strategies.
Investing in BESS provides a competitive edge in a rapidly evolving energy landscape—future-proofing your operations and delivering long-term savings.
Commercial Battery Energy Storage Systems (BESS) allow businesses to store excess electricity generated during periods of low demand or from on-site renewable sources like solar PV systems. This stored energy can then be released during peak demand times, helping reduce reliance on the grid, improve load management, and lower demand charges and overall energy costs.
Energy reliability is a critical component of operational continuity in commercial and industrial environments. Battery Energy Storage Systems (BESS) provide instantaneous backup power in the event of grid instability, voltage sags, or complete outages. By supporting uninterruptible power supply (UPS) functions and enabling seamless load transfer, BESS ensure that mission-critical systems remain online. This operational resilience minimizes exposure to downtime-related financial losses, preserves process integrity, and supports compliance with reliability standards.
Energy Contracts for Commercial Customers
As part of a forward-looking energy strategy, Solar PV and battery storage can play a big part in addressing your energy needs, but in the majority of cases the client is still left exposed to grid market uncertainty. Having addressed onsite generation and storage, the remaining power demand, that bit left for the grid to supply, is often overlooked.
We don’t overlook it. We address it.
Why securing the best energy contracts matters
Battery Energy Storage for Residential Customers
Battery Energy Storage Systems (BESS) are now seen as an essential part of a solar strategy if the customer’s budget allows. Installing PV first and then adding BESS later is quite feasible; it doesn’t have to be done all at once.
Many modern BESS systems are modular, and we can add them in stages to increase storage capacity in line with both demand and budget. Just ask us for details.
What is a battery energy storage system (BESS)?
Exactly what it sounds like; a battery or a bank of batteries that store energy, from either a solar PV installation or from the grid, or both. A BESS can also improve the stability of the electricity grid, manage energy demand, and provide backup power during outages.
What are the advantages of using battery energy storage?
Grid stabilisation, by balancing supply and demand, especially with intermittent renewable energy sources such as wind and solar
Peak shaving: Reduces the need for expensive peak-time electricity by discharging stored energy during high demand
Renewable energy integration: Stores excess renewable energy for later use, reducing dependence on fossil fuels.
Backup power: Provides a reliable backup in case of grid outages.
Reduced energy costs: Helps reduce energy costs by storing power during low-demand periods when electricity is cheaper.
How long do battery storage systems last?
The lifespan of a battery energy storage system depends on the type of battery used and its usage patterns. Typically, lithium-ion batteries last around 10 to 15 years, while other types may have shorter or longer lifespans.
What is the cost of battery energy storage?
The cost of a battery energy storage system varies widely based on its size, type, and application. In simple terms, the more storage you want (measured in kWhs), the greater the cost. And so, whilst we always try to future proof a system to some degree, there is generally a point where it doesn’t make economic sense to add more storage. We will be pleased to advise on any given situation.
How does BESS help with renewable energy integration for the UK?
BESS is a key technology for integrating renewable energy sources, such as solar and wind, into the grid. It stores excess energy when generation exceeds demand, which is then released when demand exceeds generation, thus ensuring a reliable energy supply.
Is battery storage suitable for off-grid applications?
Battery storage is a key technology for off-grid applications. It can store energy generated by renewable sources like solar panels or wind turbines and supply power in areas without access to the grid.
What are the maintenance requirements for battery energy storage systems?
Maintenance needs are generally minimal but will depend on the type and scale of the system. Regular monitoring, keeping the system clean, and ensuring proper ventilation are all important.
