Solar Panels for Warehouses & Factories
Turn your roof space into a revenue generator. Large-scale solar installations that slash operating costs and deliver measurable returns for industrial and logistics businesses across the UK.
100kWp to 500kWp Systems Built Around Your Roof and Your Operations
Warehouse roofs are the single largest untapped solar resource in the UK commercial property market. A typical 10,000 sq ft warehouse roof can support a system of 100kWp or more, while larger distribution centres and logistics hubs routinely accommodate 250kWp to 500kWp arrays generating upwards of 400,000 kWh per year. At Integral Solar, we have the engineering capability and installation experience to deliver systems across this entire range.
Roof membrane type is one of the first things we assess. Whether your building has a TPO single-ply membrane, EPDM rubber, built-up felt, composite panel or standing seam metal roof, the mounting solution needs to be matched precisely. We specify ballasted (non-penetrative) mounting systems wherever the membrane and structural loading allows, preserving your roof warranty and avoiding any risk of water ingress. Where penetrative fixings are the better engineering choice — typically on standing seam or composite panel roofs — we use manufacturer-approved clamps and sealants with full weatherproofing guarantees.
We also understand that many warehouses and distribution centres operate around the clock, with goods moving in and out continuously. Our project managers plan installation logistics around your shift patterns, delivery schedules and loading bay access, ensuring that solar work on the roof never disrupts operations on the floor. Every installation is MCS certified, carried out by our own qualified team and completed with full commissioning, monitoring setup and warranty registration.
Benefits for Warehouses & Factories
Industrial buildings are uniquely positioned to maximise the return on a solar investment. Here is why.
Massive Roof Potential
Flat or low-pitch warehouse roofs offer vast, unshaded areas perfectly suited to solar arrays. Where a domestic installation might produce 4kWp, a warehouse roof can comfortably support systems of 100kWp to 500kWp or more, generating substantial volumes of clean electricity year-round.
Significant Cost Reduction
Industrial energy bills can run into tens of thousands of pounds each year. A properly sized rooftop solar system can cut electricity costs by 40% to 60%, freeing up budget that can be reinvested into core business operations, equipment or expansion.
Rapid Payback Period
The combination of high energy consumption and large roof area means warehouse solar installations typically achieve payback within four to six years. After that, the electricity your system generates is essentially free for the remaining 20-plus years of its lifespan.
Battery Storage Integration
Pair your solar array with commercial battery storage to capture surplus generation and use it during peak tariff periods or after dark. This maximises self-consumption, reduces demand charges and provides resilience against grid outages that could disrupt operations.
Tenant Attraction
For landlords and property investors, on-site solar makes industrial units more appealing to prospective tenants. Businesses increasingly prioritise buildings with lower running costs and built-in sustainability credentials, and a solar-equipped warehouse commands a competitive edge in the lettings market.
Carbon Reporting Compliance
With SECR, ESOS and net-zero targets becoming standard business requirements, on-site solar generation provides verified, measurable carbon reductions that feed directly into your environmental reporting. Demonstrate genuine progress to stakeholders, customers and regulators alike.
Warehouse & Industrial Applications
We deliver tailored solar solutions for a wide range of industrial and logistics buildings.
Distribution & Logistics Centres
Large-footprint distribution hubs with consistent daytime energy demand are perfectly matched to solar generation. Offset the power required for conveyor systems, lighting, loading dock operations and refrigeration, reducing overheads across your entire supply chain.
Cold Storage Facilities
Refrigerated warehouses consume enormous amounts of electricity around the clock. Solar panels paired with battery storage can substantially reduce the energy cost of maintaining controlled temperatures, delivering some of the fastest payback periods in the industrial sector.
Light Industrial Units
Workshops, fabrication facilities and small manufacturing units benefit from solar just as much as larger premises. Even a modest 30kWp to 50kWp system can make a meaningful difference to monthly electricity costs while supporting your business's sustainability goals.
Multi-Unit Industrial Estates
Estate owners and managing agents can install solar across multiple rooftops, creating shared or individual systems for each tenant. This approach maximises generation across the site, enhances the estate's EPC ratings and provides an additional income stream through power purchase agreements.
How We Deliver Large-Scale Installations
A structured, proven process designed for the unique demands of warehouse and factory solar projects.
Structural & Roof Survey
Our engineers carry out a comprehensive assessment of your building's roof type, structural loading capacity, membrane condition and electrical infrastructure. We use drone surveys and detailed structural calculations to confirm your roof can safely support a large-scale solar array without modification.
Large-Scale System Engineering
We design your system to maximise generation based on your roof layout, energy consumption profile and peak demand patterns. This includes specifying panel configuration, string inverter or micro-inverter architecture, cabling routes, monitoring systems and optional battery storage integration, all presented in a clear commercial proposal.
Efficient Installation & Grid Connection
Our in-house team manages the full installation, working around your operational hours to minimise disruption. We coordinate all scaffolding, health and safety requirements, DNO applications and G99 grid connection approvals. Once commissioned, we hand over full monitoring access and register your MCS certification.
