Commercial Solar Energy Battery Storage and its Benefits for Businesses
Commercial battery storage systems are a cost effective and sustainable solution for businesses looking to reduce energy costs and increase reliability. These systems can store excess energy generated from renewable sources, providing backup power during outages and helping companies lower their carbon footprint.
- Commercial battery storage refers to the use of large-scale batteries to store energy for commercial and industrial applications.
- It is becoming increasingly popular as a way to manage peak demand, integrate renewable energy sources, and provide backup power during outages.
- The main types of commercial battery storage systems include lithium-ion, lead-acid, and flow batteries.
- These systems can be used in conjunction with solar panels or wind turbines to store excess energy for later use.
- Commercial battery storage can help businesses save money on electricity bills by reducing peak demand charges and providing grid services such as frequency regulation.
- Commercial Solar UK offer turnkey solutions that include installation, monitoring, and maintenance of commercial battery storage systems.
Commercial Solar UK installs these systems for businesses in the UK because each they reduce energy bills. We help clients achieve greater energy independence because stored power offsets reliance on the national grid.
Why UK Businesses Need Power Storage
UK electricity prices have risen by over 50% since 2021 because wholesale markets remain volatile. Battery storage systems reduce business energy costs because stored energy replaces grid imports during expensive peak hours.
Energy storage increases resilience because batteries provide backup during power outages.
How Commercial Battery Systems Work
A commercial battery system stores excess energy from solar panels or the grid because this energy can be used later when tariffs are higher.
Each system includes three core components:
- A battery that stores electrical energy safely
- An inverter that converts power between AC and DC
- Monitoring software that tracks performance in real time
Stored energy improves savings because it displaces expensive grid usage during peak demand periods.

Benefits of Business Energy Storage Systems
| Feature | Benefit | Cause |
|---|---|---|
| Energy bill reduction | Up to 40% cost savings | Stored energy offsets grid imports |
| Backup power | Business continuity | Stored charge replaces supply during outages |
| Increased ROI | Faster solar payback | Stored energy boosts self-consumption |
| Emissions reduction | Lower carbon footprint | Stored energy prevents wasted solar generation |
| Load flexibility | Peak shaving | Batteries discharge during high-tariff periods |
Each benefit strengthens energy control because batteries give businesses flexibility and savings simultaneously.
Solar + Storage = Maximum Efficiency
Pairing solar panels with battery storage increases long-term ROI because stored solar energy is reused on-site instead of exported.
Smart Export Guarantee rates are low because energy exported to the grid receives minimal compensation.
Storing that energy for internal use improves ROI because importing electricity during peak times is expensive.
We recommend combining solar with battery storage because this configuration provides the greatest financial and operational benefit.
Costs and Returns for UK Businesses
| System Size | Estimated Cost | Annual Savings | Payback Period |
|---|---|---|---|
| 50kWh | £30,000 | £4,500 | 6.5 years |
| 100kWh | £55,000 | £9,000 | 6.1 years |
| 250kWh | £125,000 | £21,000 | 5.9 years |
We calculate system size based on your peak usage profile because correct sizing maximises savings and accelerates payback.
Finance Options for Battery Storage
We offer multiple finance routes because upfront costs can delay adoption.
Available options:
- Enhanced Capital Allowances, which enable full tax relief in year one
- Capital purchase, which gives full asset ownership
- Lease financing, which spreads the cost over time
- Power Purchase Agreements, which remove the need for capex
Case Study – Hartwell Distribution
Hartwell Distribution opted to install a 120kWh battery storage system at its Leeds warehouse to address the frequent peak hour surcharges and ensure energy security for refrigerated goods. This commercial energy solution not only provides renewable power but also supports sustainability efforts by reducing grid demand during high-demand periods.
The integrated technology of this system is designed to store excess electricity from solar panels or the grid, allowing businesses like yours to control energy usage and reduce costs. Additionally, the lithium-ion batteries used in this installation have a high discharge capacity, making them ideal for industrial applications where reliability is key.
Project outcomes:
- £11,800 saved in the first year: This result occurred because stored energy replaced 71% of peak-period grid consumption.
- Payback achieved in 5.6 years: This short payback occurred because system sizing matched the site’s actual 24-hour load profile.
- Zero downtime during two National Grid brownouts: These outages caused no disruption because the battery system automatically discharged during both events.
- Carbon emissions reduced by 19.3 tonnes annually: This reduction occurred because stored solar energy covered over half of total weekday load.
System design details:
- System size: 120kWh
- Technology: LFP Lithium-Ion
- Integration: 100kWp solar PV array (installed 2022)
- Inverter: 100kW hybrid inverter
- Monitoring: 24/7 cloud dashboard with SMS alerts
“We opted for battery storage to stabilise our costs and safeguard our supply chain. The outcomes surpassed our expectations, the system not only covers its own expenses through savings but also enhances our overall efficiency.”

Frequently Asked Questions
How Long Do Batteries Last?
The lifespan of batteries typically ranges from 10 to 15 years, as they are designed to withstand over 4,000 full cycles.
Can Battery Storage Be Added to An Existing Solar Array?
Yes, modern systems support the seamless integration of battery storage into your existing solar setup. This innovative technology allows for the addition of commercial grade batteries to enhance the capacity and efficiency of your renewable energy system.
With this solution, you can store excess energy generated by your solar panels during peak production times and discharge it when demand is high or electricity rates are at their peak. The integration of battery storage with a solar array not only provides backup power during grid outages but also helps reduce overall energy costs for businesses and industrial applications.
Do I Need Planning Permission?
Usually not, because most installations fall under permitted development. We confirm this on every job because rules vary by location and system size
Can Battery Storage Work without Solar Panels?
Yes, battery storage systems can operate independently of solar panels. These systems have the capability to charge from the grid during off-peak times and discharge energy during peak hours. This flexibility allows for efficient management of power demand and ensures a reliable energy supply at all times.
