How We Help Small Businesses Go Solar

Here at Business Solar UK, we've helped small business owners just like you take the first step towards commercial solar - and now it could be your turn. Tell us about your business and your energy needs, and we'll start putting together a solar package that suits it, based on:

  • What you're looking for (in this case, solar panels for small business)
  • Your energy usage and current energy costs
  • Your roof space and how your building is used
  • Where you can make the most savings

Business Solar UK assesses your roof and your bills, and our installation partner Solar4Business surveys, designs and installs the system, with every way to pay modelled against your own numbers.

What Size Solar Panel System Does A Small Business Need?

System size follows usage, not floor space

Installing commercial solar at a small business isn't as straightforward as you might first think. Despite popular opinion, smaller businesses don't always need a smaller system. That's because the size of your solar system doesn't relate to the size of your business - it relates to the amount of energy you use day to day and what you currently pay for it.

Some smaller businesses rely more heavily on grid electricity - through equipment, laptops, lighting and the like - than some larger ones.

The best way to work out the size of system you need is to work out how much energy you use each year, and choose a system that covers it. Your free assessment does this from your actual bills, not a guess.

Benefits Of Business Solar Panels For Small Business

Cut energy bills

As a small business owner, you will have felt the effect of rising energy prices. By producing your own renewable energy on site, you rely less on grid electricity, and can start powering most, if not all, of your business with the energy your panels generate.

Increase energy security

Because you are relying more on your own generation, you are less exposed to grid disruption. That means more reliable output on days that would otherwise cost you trading time.

Renewable energy

Solar is green energy, so your business is responsible for fewer carbon emissions than before. Lowering your carbon footprint is good for your business’ image and the planet.

Increase revenue

Solar will not just save you money, it can earn you some too. Through the Smart Export Guarantee (SEG), you can sell excess solar energy you cannot use back to your supplier, which helps your system pay for itself sooner.

What To Consider Before Installing Commercial Solar Panels For Your Small Business

Solar brings plenty of benefits to a small business, but there are a couple of things worth thinking through first:

  • The upfront cost. This can be a genuine concern without capital to invest right now - though a fully funded PPA or hire purchase can remove that barrier.
  • Your location commitment. To get the best return, you'll generally want to stay at the same site until the system has paid for itself. If a move is likely soon, it may be worth waiting.

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.

FAQs

Solar Panels For Small Business FAQs

How long will solar panels for small business last?

25 years is the standard panel performance warranty, but a well-maintained modern PV system can keep generating for up to 40 years.

How much money can I save on energy bills with solar panels for small business?

It depends on how much you spend on energy each month. The bigger your bills now, the more you stand to save. Your free assessment models your own tariff and usage rather than a generic figure.

Do I need planning permission for solar panels for small business?

Usually not. In England, rooftop solar on non-domestic buildings is permitted development with no size cap, provided panels sit within set limits of the roof edge and surface. Listed buildings and conservation areas have extra rules. Your assessment confirms your specific position.

Which type of solar panel is right for my business?

Ground-mounted vs roof-mounted, monocrystalline vs polycrystalline - there are a lot of options. Your free assessment recommends the right panel type and system for your roof, budget and usage.

How many solar panels will I need?

Solar systems are customised to suit any business, large or small. Your installer works out how much of your electricity use the system needs to cover, and sizes it from there.

Can solar panels be used as part of a sustainable business strategy?

Yes. Pressure on larger businesses to install commercial solar is already real, and it is only a matter of time before it extends further down the supply chain as the UK works towards Net Zero by 2050. Moving early can be a smart business decision.

Is solar energy reliable?

Yes. Solar panel systems are low maintenance and, kept in good order, perform reliably for decades.
