Solar Panels for UK Manufacturing, Cut Energy Costs 30 to 60%

Solar built around your production, not a catalogue

UK manufacturers now pay 25p to 45p per kWh on commercial electricity contracts, roughly double the rate of three years ago, and for an energy-intensive site power is the second or third largest controllable cost behind raw materials. On-site solar is the most reliable way to take a permanent slice out of that bill. A well designed manufacturing solar system generates power exactly when a plant uses it most, so 55 to 90 percent of what it produces is consumed on site and never bought from the grid. That self-consumption, driven by your daytime and shift-based baseload, not the raw size of the array, is what decides your return.

Sized from your meter data, not a rule of thumb

We start every design from 12 months of your half-hourly meter data and roof drawings, then model the system in PVSyst and share the file. The aim is annual generation matched to 60 to 90 percent of your daytime consumption, enough to make a real dent in the bill without spilling large volumes of low-value power onto export. As a guide, one kWp of panels needs about five to six square metres of unshaded roof and generates 900 to 1,000 kWh a year in the UK, so a 3,000 square metre factory roof typically supports 450 to 550 kWp. Our savings calculator gives an indicative figure in seconds, and the cost guide sets out real prices by system size.

Funded the way that suits your balance sheet

Most manufacturing installs do not need capital up front. Asset finance spreads the cost over five to seven years and is usually cash-flow positive from month one, because the finance payment is smaller than the bill it replaces. A Power Purchase Agreement needs no capex at all: a funder owns the system and you buy the power at a fixed rate below grid. If you buy outright, 100 percent Annual Investment Allowance lets a profitable company deduct the full cost from taxable profit in year one, and VAT is reclaimable for VAT-registered businesses. We model cash, finance and PPA side by side, with the return on each, on the grants and funding page.

Every manufacturing sector is different

A food and beverage plant with 24/7 refrigeration, a pharmaceutical site with cleanroom HVAC, a plastics moulder with chillers, and a metal-fabrication workshop with welding and compressed air all size and pay back differently. That is why we build around the sector rather than swapping a noun on a template. Explore the profile for food and beverage, automotive, pharmaceutical, chemical and process, textile and engineering and metalworking manufacturing, each with its own typical sizing, payback and compliance notes. If you run a single dedicated factory building rather than a broader industrial or multi-process site, our sister guide to rooftop solar for factories covers that narrower case in more depth.

Grid connection is usually the long pole

For anything above 100 kW, the G99 grid-connection application is often the longest item in the programme, with Distribution Network Operator timescales of 6 to 18 months on constrained networks. We submit the application alongside the structural survey so the clock starts on day one, and where export capacity will not arrive in time we phase the design with battery storage so you get immediate self-consumption while waiting. Local grid capacity, DNO timelines and council net-zero targets all shape a project, so each of our area guides covers the local picture for a major UK manufacturing centre.

An honest specialist, not a clipboard sales call

We are MCS-certified for commercial work, NICEIC-registered, and RECC and TrustMark licensed, and every install is covered by a ten-year IWA insurance-backed workmanship warranty on top of the 25-year panel performance warranty. If your roof, load profile or tenure do not suit solar, we will say so. The proposal is fixed price: what you sign is what you pay.
