Commercial solar designed around your site and electricity use.
Reduce imported electricity, make better use of your roof and build a clearer long-term energy strategy — with a system designed around when your business actually uses power.
- Site-specific design
- DNO and connection support
- Solar and battery integration
- Monitoring and aftercare
Tell us about the site.
Even rough figures help. A bill is enough to start.
Site-led design
Designed for the building, roof and operating environment.
Load-led modelling
Sized around demand, self-consumption and future loads.
Grid-aware
Connection and export requirements considered early.
Long-term support
Monitoring, handover and a clear aftercare route.
Start with the operating profile, not the number of panels.
Commercial solar can improve several parts of the energy strategy. The useful system size depends on roof space, daytime demand, connection limits and what the business needs to achieve.
Use the roof before buying from the grid.
Solar can supply part of the site's daytime electricity demand directly, reducing the amount imported at the prevailing business tariff.
- Generate electricity where it is consumed
- Reduce exposure to imported energy prices
- Model savings against real operating hours
A large roof does not automatically mean the right system.
The design needs to connect roof potential, electricity demand, connection limits and the investment objective. These are the four inputs that shape a credible proposal.
Consumption profile
Annual use, half-hourly demand, operating hours and expected changes to site load.
Roof, land and shading
Usable area, orientation, shading and any practical or planning constraints.
Structure and access
Roof condition, structural considerations, safe working space and installation access.
Electrical design
Supply capacity, distribution, metering, protection and inverter arrangement.
Connection and export
DNO requirements, agreed supply capacity and any export-limitation strategy.
Business case
Self-consumption, tariffs, capital route, target return, carbon goals and project timescale.
85kWp rooftop solar for a Birmingham construction business.
Sunergy installed a 160-panel rooftop array with a 75kW FOX ESS inverter, designed around the available roof and the client’s commercial electricity demand.
- 85kWp installed solar capacity
- 160 roof-mounted solar panels
- 75kW FOX ESS inverter
- Approximately 70,000kWh predicted annually
- Projected payback under six years
Generation and payback are forecasts based on the project design and agreed assumptions. Actual results vary with weather, consumption, tariffs, availability and other site factors.
70,000kWh a year means less electricity bought from the grid.
The forecast annual generation gives the client a practical starting point for assessing energy savings, carbon reduction and the return on the installation.
The important figure is not simply how much the array can generate. It is how much of that electricity the business can use on site, what would otherwise have been paid for grid power and how the assumptions hold up over time.
- Forecast annual generation stated clearly
- On-site consumption considered in the design
- Tariff, export and performance assumptions disclosed
A commercial solar project should have a clear engineering route.
Each stage should reduce uncertainty, verify the design and make the next decision easier for the business.
Initial data review
Review bills, operating hours, the site, project goals and any half-hourly data available.
Desktop feasibility
Assess roof or land potential, indicative generation, self-consumption and connection considerations.
Survey and proposal
Verify access, structure, electrical infrastructure, scope, equipment and commercial assumptions.
Delivery and aftercare
Install, commission, configure monitoring, complete handover and provide the agreed support route.
Built for the roof, the electrical system and the business case.
Commercial solar is more than panels. The array, inverter, protection, cabling, monitoring and handover all need to work as one installation.

Commercial solar, without the vague sales claims.
A bill is enough to begin. Half-hourly data, a roof plan and details of future electrical loads make the first assessment better.
