Practical project guidance
Clear project information helps you compare options and ask the right questions before choosing an installer.
Solar at industrial scale
Industrial solar panel installation lets large facilities generate renewable electricity at scale, reducing dependence on the grid and improving long-term energy security. Factories, warehouses and production plants use a lot of electricity, often during daylight hours, which makes solar a practical way to cut operating costs while working towards sustainability goals.
The benefits for industrial users include savings on energy bills, less exposure to market volatility and support for environmental and ESG targets. Solar also demonstrates corporate responsibility to customers and investors. Why not combine it with general electrical work for a complete upgrade?
Delaying solar leaves facilities more exposed to rising energy costs and can mean missing financial opportunities, which matters most for energy-intensive industries.
Feasibility and design
The process begins with a feasibility assessment covering roof or land area, structural capacity, shading and your energy profile. Systems are then designed to maximise useful output and fit your existing infrastructure. Roof-mounted systems need a structural survey and, on older buildings, checks on the roof covering and any fragile materials. Ground-mounted arrays need suitable land and cable routes.
Grid connection, standards and planning
- Network connection: systems above 16 A per phase, which includes most industrial arrays, need the network operator's approval before connection under the Energy Networks Association's G99 process. Applying early matters, because export capacity can be limited in some areas.
- Wiring standards: the installation is designed and tested to BS 7671:2018+A4:2026, including Section 712 for solar PV, and recorded on an Electrical Installation Certificate (EIC). Amendment 4 also added requirements for stationary battery storage.
- Safety: installation is construction work under CDM 2015, and roof work must be planned under the Work at Height Regulations 2005.
- Planning: rooftop solar on non-domestic buildings is often permitted development, subject to conditions, but ground-mounted arrays and some locations need planning permission. Check with your local planning authority.
Export and monitoring
Under the Smart Export Guarantee (SEG), licensed electricity suppliers must offer a tariff for exported electricity from eligible systems up to 5 MW, with rates set by each supplier. Once operational, monitoring platforms let facility managers track generation, consumption and savings. Adding battery storage can increase self-consumption and support critical loads. To explore the most suitable options, many organisations use solar comparison services for industrial sites.
Industrial solar is a strategic investment: generating electricity on-site makes costs more predictable and strengthens resilience. Compare quotes through Kilowatts UK, or call free on 0800 009 6058.
