Solar panels with Battery Energy Storage: power your business day and night

Battery energy storage for self-use that lets UK businesses store surplus solar on-site and use it later - reducing grid reliance, peak tariffs and operating costs.

  • Maximise ROI

    Use 100% of your solar generation on site

  • Lower bills

    Use stored solar to cover peak demand

  • Clean up operations

    Cut reliance on grid electricity

Make the most of your solar power with battery energy storage for self-use

Solar panels deliver clean, low-cost electricity - but without storage, much of that value is lost. Our grid-tied battery energy storage systems (BESS) capture excess solar generation during the day and discharge it when you need it most, helping your business maximise self-consumption, cut energy costs, and reduce reliance on the grid.

Choosing the right battery system can make or break your solar investment

Adding battery storage sounds simple - but not every system is built the same, and not every supplier understands how to integrate one effectively. Many businesses rush into low-cost or poorly specified installations that fail to deliver real savings: batteries sized incorrectly to optimise your storage potential, systems that don’t communicate with existing solar setups, or technology that underperforms after just a few years. The result? A system that looks good on paper but wastes energy, time and money in practice.

At Energy Solutions, we help you avoid those pitfalls with systems designed to help recoup your capital outlay as quickly as possible. With over 30 years’ experience designing hybrid and grid-tied systems, our engineers specify the right battery energy storage for solar self-use, ensuring your system delivers consistent performance, long-term reliability and measurable returns.

How much can I expect to save with a solar-connected battery energy storage system?

Savings depend on how your business uses power, your tariff structure and how much solar energy you generate - but most organisations see a 40–70 % reduction in imported electricity once a battery system is installed.

A solar-connected battery energy storage system (BESS) allows you to use more of the power you already produce, avoiding high daytime tariffs and smoothing out demand spikes.

By maximising solar self-consumption, typical commercial sites achieve payback within three to five years, with continued savings throughout the battery’s 10–15 year lifespan.

At Energy Solutions, our modelling team uses your real-world generation and consumption data to forecast savings accurately before installation - so you can see your expected ROI and carbon reduction before you commit.

Other financial benefits often include:

  • Peak-tariff avoidance

    Discharge stored solar during the most expensive grid periods.

  • Lower demand charges

    Flatten consumption peaks and avoid excess-capacity penalties.

  • Reduced diesel use and maintenance costs

    Where backup generators are in place.

  • Improved ESG and carbon reporting

    Supporting tender and investor requirements.

Our EasyGrid grid-tied battery energy storage systems (BESS) don’t just optimise your solar investment...

Limited power supply management

Grid-tied storage covers demand spikes so you can expand operations without breaching your grid connection cap.

Time-of-day usage

BESS allow you to store electricity at night when tariffs are low and use it during the day when grid electricity is most expensive.

Real-world solar self-use scenarios

Warehouse-Interior
Distribution warehouse – powering evening shifts

A Midlands warehouse with 1 MW of rooftop solar was exporting most of its midday output. By adding a 500 kWh BESS, it now stores surplus and discharges it to power evening loading shifts.

Result: £45,000 annual savings and a stronger sustainability report for clients.

School_Classroom
School campus – using summer solar smartly

A large secondary school generates excess solar during summer holidays. A modular BESS stores this surplus to cover late afternoon and evening demand when activities restart in September.

Result: predictable bills, higher self-consumption and reduced evening grid reliance.

Cold-Storage
Food manufacturer – keeping refrigeration clean

A food plant with large chiller loads needed reliability in the late afternoon when solar output dropped. A solar self-use BESS charges during peak sunshine and discharges to cover refrigeration until night.

Result: stable operations, reduced diesel backup and stronger compliance with ESG goals.

How we deliver your solar self-use system

Step 1 - Discovery & modelling

We analyse your solar generation, consumption patterns and grid connection to predict savings using industry-standard solar modelling tools.

Step 2 - Design & installation

Our engineers determine the right battery capacity, design the full electrical architecture, and integrate the system with your existing solar PV and switchgear.

Step 3 - Monitoring & optimisation

Your battery energy storage system (BESS) is remotely monitored by our UK team, who track performance data, fine-tune settings and provide proactive maintenance to keep efficiency high year after year.

Why so many solar investments underperform

Across the UK, businesses are exporting valuable solar electricity back to the grid for pennies - then buying it back later at full price. That’s lost profit, higher operating costs and slower progress toward sustainability goals. Too often, the problem isn’t the panels - it’s the system design. A poorly specified or disconnected setup means wasted generation, unreliable performance and missed savings.

At Energy Solutions, we help you avoid those pitfalls. Our solar self-use battery energy storage systems (BESS) are engineered to capture, store and reuse your own renewable power efficiently - reducing grid reliance, improving ROI and strengthening your ESG performance year after year.
