Battery Storage
Commercial Battery Storage for Existing Solar PV
If you already own commercial solar PV, battery storage could be the next step in getting more value from the energy you generate. But at HIT Energy Services, we don’t start with the battery. We start with the solar asset you already own.
Before deciding what size battery you need, how it should charge or whether additional solar makes sense, we want to understand exactly how your existing PV is performing. That’s where HIT Energy Guard comes in.
Your Solar Is Generating. But Is It Generating What It Should?
Older commercial PV systems can continue operating while quietly losing generation through ageing modules, inverter issues, string faults or developing electrical problems. HIT Energy Guard gives us an independent view of the asset before we decide what comes next.
Two Routes – Depending on What the Data Tells Us
If the PV is underperforming, Simon and the HIT team investigate why. The answer may be maintenance, repair or repowering. We won’t replace perfectly good equipment unnecessarily. If existing inverters, electrical infrastructure or mounting systems remain suitable, we’ll look at retaining them.
If the PV is performing brilliantly, great – leave it generating. We can then look at export, site demand and whether a standalone commercial battery could capture surplus solar for use later.
Repower, Expand and Store
Modern higher-efficiency modules can sometimes achieve the required capacity using fewer panels. Where suitable, repowering may release existing framework for additional PV, which can then be considered alongside battery storage.
MONITOR → MAINTAIN → REPOWER → EXPAND → STORE → OPTIMISE
HIT Energy Guard Stays at the Centre
HIT Energy Guard was built by us more than a decade ago to independently monitor legacy solar PV. We are now using historic half-hourly solar generation and weather data alongside live PV performance, site demand, weather forecasts, electricity tariffs and AI-supported analysis to develop intelligent battery management.
The aim is to determine when compatible batteries should CHARGE, HOLD or DISCHARGE – whether from surplus solar, lower-cost grid electricity or a combination of both.
One Platform. One Monthly Subscription.
Where compatible battery storage is integrated with HIT Energy Guard, AI-supported battery management is included within the usual HIT Energy Guard monthly subscription. Solar PV monitoring and intelligent battery management work together within the same service.
Commercial Battery Storage in Action – Skegness
At a large holiday park in Skegness serving around 300 caravans, HIT worked with the site’s existing solar PV and electrical infrastructure to integrate additional generation and commercial battery storage. Rather than starting again, we assessed what was already there and designed the solution around the site’s actual demand and electrical constraints.
Understand what you’ve already got. Keep what works. Improve what doesn’t. Then decide what comes next.

Start With the Asset You Already Own
If you already have commercial solar PV, our first question isn’t “What size battery would you like?” It’s “What is your solar doing today?” Let us understand the generation, performance, consumption and export first. From there, we can determine whether the opportunity is maintenance, repowering, additional PV, standalone battery storage – or a combination.
Additional FAQ Questions
Are commercial battery storage systems worth the investment?
For many businesses, yes. Battery storage allows you to store lower-cost or self-generated electricity and use it when energy prices are higher. Combined with solar PV, this can significantly reduce electricity costs and improve the return on your renewable energy investment.
How much can a business save with battery storage?
Savings vary depending on your energy usage, tariff structure and battery size. Businesses with high daytime electricity consumption or large solar PV systems often see the greatest financial benefit.
Can battery storage be installed without replacing my existing solar system?
Yes. Many commercial battery storage systems can be integrated with existing solar PV installations. Our engineers will assess your current equipment and recommend the most suitable solution.
How long does installation take?
Most commercial battery storage installations can be completed within a few days, depending on the size and complexity of the project. We’ll provide a detailed installation programme before work begins.
Do you install battery storage across the UK?
Yes. HIT Energy Services provides commercial battery storage installation, maintenance and support for businesses throughout the UK.
