As Tesla-certified specialists, we are the experts in the consultation, design and installation of commercial solar battery storage systems for businesses.

What is commercial battery storage?

Solar batteries, a key component in industrial battery storage, are large energy storage units typically found outside a building that charge up during sunny periods if linked up to a solar PV system, or during the night from the grid if there are low energy demands. This makes them an excellent option for commercial battery storage in the UK.

The batteries’ Dynamic Firm Frequency Response (DFFR) will monitor and discharge the stored energy. The solar batteries themselves are made up of rechargeable lithium-ion, stored in smaller battery packs within the units.

Combining a battery with commercial solar panels for your business can help revolutionise your organisation’s energy management and carbon savings.

Commercial Battery Storage Explained

Commercial Solar Battery Storage Can Be Used To:

  • Reinforce or reduce your electrical requirements
  • Generate revenue by offering grid services
  • Provide backup power
  • Capture excess exported energy from wind or solar
  • In some cases, provide Uninterrupted Power Supply (UPS).

Check out our in-depth solar battery guide to see if it’s worth it for your business.


Backup power

Backup power

Commercial solar battery storage systems have the capability to provide backup power to your business, much like diesel standby generators. These commercial battery storage systems store power to release during periods of power outage and capture any excess energy generation.

This gives you peace of mind that your site will continue to operate in the event of power supply disruption, solidifying their role as essential commercial energy storage solutions.

In certain cases, your business may benefit from an Uninterrupted Power Supply (UPS), a feature often sought after in industrial battery storage solutions. This eliminates the short period of downtime that occurs when switching over to your backup solar PV battery storage in a conventional system – see the section on UPS below for more information.

Uninterrupted Power Supply

Uninterrupted Power Supply

An Uninterrupted Power Supply (UPS) ensures that your business does not experience any dropouts during power outages, meaning your computer systems can remain online, the lights can stay on, and your teams can keep working.

UPS is a rapid response commercial solar battery storage UK system: should power fail, then the supply to your business will go on without any interruption. They are often used for short durations while a standby generator or a backup battery storage system kicks in to take the load.

These solar battery systems protect the continuity of your business activities, which is particularly important for companies that depend on power for essential technology or sensitive equipment that could malfunction during a power dropout. 

Our commercial battery storage for solar ensures that your operations are safeguarded, emphasising our commitment to reliable industrial solar battery storage solutions.

Grid services

Grid services

Your business can provide grid services, which protect and stabilise the grid during periods of disruption. From this, you can earn an income by offering your commercial solar battery storage to the National Grid.

This process is often accessed through an aggregator, which controls and manages the commercial battery storage systems on your behalf to extract revenues by providing grid services to the National Grid through contracts the aggregator secures.

Grid Services Revenue Streams

Enhanced Frequency Response (EFR): Commercial battery storage units excel in offering EFR, allowing businesses to swiftly balance the grid and monetize their quick response capabilities.


Frequency Response: Commercial and PV battery storage systems provide a frequency response service, stabilizing the grid’s power supply and generating revenue for participants.


Capacity Markets: In the UK, industrial battery storage solutions are crucial for capacity markets, ensuring energy availability and offering a consistent revenue stream.


Triad Avoidance: Firms in the UK can utilize PV system battery storage to minimise energy consumption during peak demand, optimizing transmission costs and enhancing energy efficiency.


Load Shifting: Businesses with commercial solar battery storage systems can shift energy consumption to off-peak periods, capitalising on lower energy costs and earning incentives for easing grid demand.


Peak Shaving: By employing commercial energy storage, companies can reduce reliance on the grid during peak hours, cutting energy expenditures and contributing to the stability of the power network.

Load shifting

Load shifting

Using solar panel battery storage for load shifting means managing the electrical load profile of your business to even out its distribution. Your organisation benefits from cheap energy at certain times whilst capturing excess exported power generated from renewable technology.

Your business can reduce energy costs by charging the commercial solar battery storage when energy is cheap: either at night via the grid when tariffs are low and/or during the day with excess solar or wind generation. The power can then be ‘shifted’ to periods when energy is expensive (during the day and peak periods.)

Operating the solar PV battery storage in this way will typically flatten out your company’s demand for energy from the grid, giving you savings and helping to offset more of your carbon emissions. Load shifting can also help avoid the expense of upgrading your electrical connection by reducing the demand during peak periods and managing the load to fall within your agreed kVA capacity. 

We are able to provide bespoke commercial solar battery storage UK solutions to meet your business needs whilst offering maximum financial and environmental gains.

Peak shaving

Peak shaving

Operating your industrial solar battery storage in peak shaving mode will enable you to avoid going over your agreed kVA capacity. During these periods, your business can be penalised heavily for using power, therefore, this can make a huge difference in achieving your financial objectives.

Transmission charges (kVA standing charge) from electricity suppliers are an expensive element of your company’s energy bill. Offsetting your peak load demand with energy stored in a commercial battery storage system will flatten your demand at these peak points and ultimately create substantial savings on your energy bill.

Reducing your peak consumption with industrial solar batteries will also save money on distribution charges levied by electricity suppliers during these more expensive periods. This means that you can reinvest the money you’ve saved back into your business, therefore providing a source of sustainable growth. 

If you are a growing business with increased energy demands, a solar PV battery storage system might be what you need to manage this, reducing costs and risk to your businessget in touch to find out more.


What is the best way to store batteries for commercial use?

For optimal storage of commercial batteries, maintain them in a cool, dry environment and at a recommended state of charge. Regular maintenance checks are crucial to ensure safety and efficiency. Incorporating management systems for monitoring can also prolong battery life and performance.

Which battery is best for storage in PV systems?

Lithium-ion batteries are often the best choice for PV battery storage due to their high energy density, efficiency, and longer lifespan. They are suitable for commercial battery storage in the UK where performance and space are critical considerations.

What is the most efficient battery storage system available in the UK?

The most efficient battery storage system currently available for commercial purposes in the UK is typically a lithium-ion-based system. It offers superior charge/discharge efficiency and energy density, which is essential for maximising the returns on investment in solar battery storage.

Is it worth having a battery storage system for my business?

Investing in a battery storage system can be very worthwhile for businesses looking to reduce energy costs, improve resilience, and support sustainability goals. Solar battery storage companies can provide tailored solutions that ensure businesses in the UK meet their specific energy needs efficiently.

What size solar battery storage do I need for my commercial facility?

The size of the battery storage you’ll need depends on your energy usage patterns, the capacity of your PV system, and your energy objectives. It’s essential to consult with a battery storage specialist who can analyse your requirements and suggest a system that meets your commercial needs without unnecessary expenditure.
