Commercial Solar Panels
Roof- and ground-mounted commercial solar PV, sized around how your building actually uses power.
Commercial solar is one of the surest ways to cut both energy costs and carbon. We design, install and maintain arrays sized to your load, from small units to multi-hundred-kilowatt schemes like Booker Watford's 334 kWp system.
Because we also re-roof, we can replace a tired roof and install the array in one coordinated programme, with a combined warranty.
Cut operating costs and invest in a greener future with solar panels for commercial buildings. As power costs rise and carbon targets tighten, we deliver tailored commercial solar systems that provide reliable, low-carbon power without disrupting day-to-day operations.
What’s included
How we install solar on commercial sites
- Site assessment and feasibility: matching solutions to your roof space, land availability, structural load limits and electrical capacity, across rooftops, car parks and ground-mounted areas.
- Power planning and future-proofing: modular, scalable systems designed around fluctuating seasonal and sector demand.
- Smart infrastructure design: layouts that integrate with existing electrical infrastructure to UK electrical standards for reliable, low-maintenance systems.
- Installation and integration: full installation including batteries, inverters and grid integration, coordinated with on-site teams.
- Commissioning and handover: fully tested and certified to BS 7671 (IET wiring regulations), with performance visibility from day one.
Why get commercial solar panels
Energy cost savings and lower electricity bills, with excess energy sold back to the grid; longevity and low maintenance; clean, renewable energy that cuts your carbon footprint; and greater independence from the grid with reduced exposure to outages and price rises.
Sectors we serve
Retail, education, industrial, commercial, healthcare and leisure, with a system tailored to your energy needs.

Commercial solar panels questions answered.
Can't see your question here? Our team is happy to talk it through.
Is our roof or site suitable for commercial solar?
Our site assessment looks at your roof space, land availability, structural load limits and electrical capacity. We consider rooftops, car parks and ground-mounted areas to find the best fit for your site.
Will installing solar disrupt our day-to-day operations?
We deliver commercial solar without disrupting day-to-day operations. Installation, including batteries, inverters and grid integration, is coordinated with your on-site teams.
Do you deal with the DNO application and grid connection?
Yes. DNO applications, export limiting and grid integration are all included as part of our service.
What happens to the electricity we don't use?
Systems are designed to prioritise on-site consumption, so you use as much of your own power as possible. Excess energy can be sold back to the grid.
How will we know the system is performing as it should?
Every system is fully tested and certified to BS 7671 at commissioning, and includes performance monitoring so you have visibility from day one. Systems are designed for 25-year performance.
