Store the solar energy you generate but don't use straight away, and draw on it when your panels aren't producing. Start with a free assessment of your site and your bills.
Batteries suit any business already generating, or about to generate, solar power
Business Solar UK has helped plenty of businesses just like yours discover the benefits of commercial solar battery storage. We assess your existing or planned solar system and your electricity use, and our installation partner Solar4Business designs and installs the battery that fits, based on:
We'll set out a tailored proposal for adding storage to your business, whatever stage you're at.
There are a number of benefits to battery storage for commercial solar installations. Yes, it comes at an additional cost, but most business owners think the extra cost is worth it.
Your solar panels generate energy for your business regardless of whether you can use it straight away. A battery stores it for use later, instead of exporting it for a lower return.
Solar energy is cheap energy. The more of it you use, the less you rely on the grid, and the more you save.
The more solar energy you use to power your business, the smaller your carbon footprint.
A standard grid-tied battery still switches off in a power cut for safety, like the panels themselves. Backup power through an outage needs a battery system specifically designed for it, with supported circuits - your installer can specify this if it matters to you.
A commercial battery reduces how much you draw from the grid day to day, cutting your exposure to peak-rate pricing.
A commercial battery acts as a storage solution between your solar panels and the appliances in your business that they power.
Your solar panels produce electricity for your business needs as normal, but if you don't need to use the electricity they generate at the time, it can be stored for later instead of exported at a lower rate.
When your panels are no longer producing electricity, or aren't producing enough to power your business, such as at night or during overcast weather, the electricity stored in the battery can be drawn on to make up the gap. This reduces how much you draw from the grid, but by default it does not keep you running during a grid power cut - a standard grid-tied system switches off automatically for safety. Backup during an outage needs a battery specifically designed for it, with supported circuits, which your installer can specify.
Cost depends heavily on whether you already have solar installed, the battery you choose, and the size of your array.
If you already have a commercial solar installation at your business premises, adding battery storage to it is usually more straightforward and cheaper than a brand new install. Your assessment confirms an accurate cost against your own equipment.
If you're planning a new commercial solar installation with battery storage from the outset, cost depends on the battery you choose, the size of your solar array and the panels you select. Fill out your details with us to receive an accurate quote for your site.

Illustrative examples, not live quotations. Equipment, warranties and prices are confirmed in your proposal. All savings are based upon a solar generation yield of 850kWh/kWp installed per annum, with usage of 71.43% of solar energy generated, assuming a 24p/kWh electricity import rate (close to the DESNZ Q1 2026 UK non-domestic average of 24.14p/kWh). Savings may change year on year dependent upon weather conditions, energy prices and system degradation in line with warrantied output.

When it comes to commercial solar, there are a few ways to purchase your system. We’ll help to guide you through your options.
Using the Annual Investment Allowance, you can deduct the cost of your system against corporation tax.
Spread the cost with asset financing and use your bill savings to pay off your annual loan repayments.
Purchase your system outright, for the best return on investment.
Or pay nothing upfront with a solar power purchase agreement. See all four ways to pay.

"All went well with the initial enquiry, report draft and install. We were kept up to date with install dates and the guys on site were tidy and professional... There has been a marked reduction in our electricity costs which was the reason for the install."
"Steve and his team were extremely professional, installing over 900 panels for our Academy."
"We have a commercial property and 48 solar panels have been fitted. The team of installers were extremely professional and helpful."
"A great installation. Steve and the team did a great job. Would not hesitate to recommend this company."

It varies, because every commercial solar installation is different. As a rule, a battery increases the proportion of your own solar generation you use on site rather than exporting or drawing from the grid, which reduces your bill further on top of the panels alone.
It depends on the scope of your project. Larger businesses will need larger batteries, and potentially more than one. Contact us with your energy needs and Solar4Business will advise on sizing as part of your assessment.
For many sites, yes. Using more of the solar energy you already generate, rather than exporting it at a lower rate, is often the strongest case, alongside the added energy security and reduced reliance on the grid.
In most cases, yes. It is usually more straightforward and cheaper to add a battery to a system you already have than to add one as part of a brand new installation. Your assessment confirms compatibility with your existing inverter and panels.
Very little. Most commercial batteries are low-maintenance, with monitoring built in so any fault is flagged early. See our guide to commercial solar panel maintenance for how your wider system is looked after.
The battery works alongside the grid, not instead of it. It charges from your solar generation and discharges to cover your site’s demand when your panels aren’t producing enough, only drawing from the grid once the battery is depleted.
Save massively on your electricity bills when you invest in solar.
