Commercial Solar PV Installation
Rooftop and ground-mount solar PV for commercial, industrial and public sector sites, UK-wide. Every system is specified using PVSol performance modelling and location specific irradiance data, engineered around your load profile and commercial objectives.
Performance-modelled system design
Every system is sized using PVSol performance simulation, factoring in site location, roof orientation, pitch and shading, combined with location specific irradiance data. The same modelling rigour applies to every system we install, from 20kW rooftops to multi-megawatt arrays.
Sites with high daytime demand typically see solar PV cover a substantial proportion of annual electricity consumption, with payback of 4-6 years depending on system size, tariff structure and load profile.

- ✓Full sign off certification and handover, issued on completion
- ✓Ongoing aftercare: support and remote monitoring for the operational life of the system, with a full O&M service available
While we are not tied to any panel manufacturer, quality drives our product selection process. Every panel we specify is Bloomberg Tier 1 rated for proven quality and financial reliability, and fully labour traceable, so you can be confident there is no modern slavery risk in the manufacturing supply chain.
Every system is specified from the wider market of proven manufacturers to match your roof, budget and performance goals, not to move a particular product.

Discuss your project →From survey to switch-on
For a smaller commercial system, allow 12 to 24 weeks from survey to switch-on, much of it waiting for grid approval. Larger projects take longer.
- 01
Free drone survey
We capture accurate roof and site data by drone, without scaffolding or access equipment, and check the structure can carry the load.
- 02
PVSol design and proposal
Your system is modelled in PVSol around your roof, shading and load profile, so the proposal shows realistic generation, savings and payback.
- 03
G99 grid application
We design and submit the G99 application to your network operator. Approval alone can take around 12 weeks, so it starts as soon as the design is agreed.
- 04
Planning and pre-construction
We confirm the planning position, prepare glint and glare reports where needed, and manage the works under the CDM Regulations 2015.
- 05
Installation
Our own installation teams carry out the work, typically one to three weeks on site for a smaller commercial system, scheduled around your operations.
- 06
Commissioning and handover
The system is tested, commissioned and signed off, and you receive full certification and handover documents.
- 07
Monitoring and aftercare
Remote monitoring keeps track of performance, with a full operations and maintenance service available if you want it.

Paying for your system
You can buy your system outright, or if you would prefer to spread the cost, we can introduce you to our finance partners.
Where local grants are available for your area or sector, we will send you the details so you can apply.
Looked after once it's running
Remote monitoring tracks your system's performance, and we offer a full operations and maintenance (O&M) service if you want it.
Panels, inverters and batteries carry the manufacturer's product warranty, which varies between manufacturers. Our own installation work is covered by an insurance-backed workmanship warranty.
What sets us apart on commercial solar
In-house design
Every system is designed and modelled by our own team, not outsourced, so the people who design it understand your site.
Our own installation teams
The work on your roof is carried out by our own installers, giving you one team accountable from survey to sign-off.
Principal Contractor capability
We can take the Principal Contractor role and manage the whole project, or join an existing team for the parts that need our expertise.
Listed buildings and unusual sites
From a bifacial solar promenade on a Victorian pier to a 4.1MW multi-phase research campus, we are experienced with sites that need a specialist approach.
Commercial solar PV: technical and commercial questions
What is the typical project timeline, from survey to switch-on?
For a smaller commercial system, allow 12 to 24 weeks from survey to switch-on. The G99 grid connection application to your network operator can take around 12 weeks on its own, so we submit it as soon as the design is agreed. Time on site is typically one to three weeks for a smaller system. Larger projects take longer, and the timeline varies with system size and site.
What size of commercial system do you install?
We install commercial systems from 20kW upwards, from single rooftops to multi-phase, multi-megawatt projects such as the 4.1MW array at Harwell Science Campus. Whatever the size of your site, we are happy to talk it through.
How can we fund a commercial solar system?
You can buy your system outright, or if you would prefer to finance it, we can introduce you to our finance partners. Where local grants are available for your area or sector, we will send you the details so you can apply.
What are the planning requirements for a commercial rooftop system?
In most cases, none. Rooftop solar on commercial buildings usually falls under permitted development rights in England, provided the panels do not protrude more than 200mm and the building is not listed or in a conservation area. We confirm the planning position for your specific site as part of the free survey.
How is surplus generation handled?
Surplus generation is exported to the grid and paid for under the Smart Export Guarantee (SEG), or stored in a battery system for use later. Systems are designed around your consumption profile so the majority of generation is used on site, which is where the greatest financial benefit lies.
What ongoing operations and maintenance is required?
Solar PV has no moving parts, so requirements are minimal: an annual inspection and periodic panel cleaning depending on location, with remote monitoring flagging performance issues automatically. If you would rather hand it over completely, we offer a full operations and maintenance (O&M) service.
What warranties come with a commercial system?
Panels, inverters and batteries carry the manufacturer's product warranty, and the terms vary between manufacturers. Our own installation work is covered by an insurance-backed workmanship warranty.
Which roof types and structures can accommodate solar PV?
We install on pitched metal, flat membrane, fibre cement and standing-seam roofs, plus ground-mounted arrays where roof space is limited. Every project starts with a structural assessment to confirm the roof or ground condition can carry the load, included in the survey.
