Installing commercial solar panels is one of the most effective ways for UK businesses to cut energy costs, improve sustainability performance, and secure long-term resilience. But a successful project depends on choosing the right partner, one with engineering expertise, strong safety standards, and a proven commercial track record.
Spirit Energy is an established commercial solar installer working across the South of England. Our engineering-led approach ensures accuracy at every stage, from feasibility studies to commissioning.
Below is the full 7-step process we follow for every commercial solar panel installation project.
Your project begins when you contact our commercial team.
We gather essential information about your site and operations, including:
This gives us enough data to outline the scale and feasibility of a commercial solar panel installation for your business.
Our engineers complete a detailed remote assessment using:
We then prepare:
This confirms early technical viability before committing to on-site engineering.
Once the concept design is approved, we prepare a detailed commercial proposal outlining:
As your commercial solar panel installers, we handle all DNO submissions and regulatory paperwork on your behalf. Most projects will undergo a feasibility study cost prior to final order being placed to ensure all permissions are obtained e.g., roof being strong enough, DNO permission, and planning permission if applicable.
A senior engineer attends your site to conduct a full technical survey, reviewing:
Where required, we arrange structural engineering calculations for compliance.
This step finalises the technical design ahead of installation.
Following approvals and final placement of the order, our in-house commercial solar installation team completes the full build.
This includes:
Access equipment (scaffolding/MEWP)
Mounting frame installation
Module mounting
Inverter and switchgear installation
Cable runs and protection setup
Monitoring system configuration
G99 protection testing
System commissioning
Submission of all certificates and documentation
A typical commercial installation schedule is planned around business operations to minimise downtime.
Once your system is live, we provide:
Your team will be able to track performance, consumption and alerts in real time.
To maintain maximum yield and system longevity, we provide ongoing:
This ensures your commercial solar panels continue delivering strong financial and environmental returns year after year.
System size, roof type, structural requirements, grid connection, access equipment and inverter configuration all influence cost.
Most projects take several days to a few weeks depending on system size and complexity.
Yes. We design ballasted or mechanically fixed mounting systems depending on roof structure, membrane type and engineering requirements.
Spirit Energy provides commercial solar panel installation across the South of England.
Do I need planning for my building?
Most commercial units won't need full planning permission as long as the panels are at least 1m from the edge of the roof and there are no other complications e.g. conservation area or a listed building. 50kWp systems and above will require a prior approval application which we would include as part of our service.
