What Are the Installation Requirements for Commercial Solar Panels?
Commercial solar panel installation involves several key requirements. These include assessing the roof structure, determining space needs, following planning guidelines, and addressing grid connections.
Roof Structure Assessment
Before installing commercial solar panels, you need to check your roof’s condition and strength. A structural engineer should inspect the roof to ensure it can handle the extra weight. Solar panels typically add about 15-20 kg per square metre.
Your roof must be in good repair, with no leaks or damage. If repairs are needed, it’s best to do them before fitting the panels. The roof’s angle and direction also matter. South-facing roofs at a 30-40 degree tilt are ideal for maximum sunlight exposure.
Space Requirements
The amount of roof space you need depends on your energy goals. A rough guide is 10 square metres per 1 kW of solar panels. For a 30 kW system, you’d need about 300 square metres of roof space.
Consider these factors when planning your layout:
- Shading from nearby buildings or trees
- Access paths for maintenance
- Space for inverters and other equipment
A professional solar panel installation service can help you design an efficient layout for your site.
Planning Permission Guidelines
Most commercial solar panel installations in the UK don’t need planning permission. They often fall under ‘permitted development’ rules. But there are some limits:
- Panels shouldn’t stick out more than 20 cm from the roof slope
- They can’t be higher than the highest part of the roof (excluding chimneys)
- For flat roofs, panels must be at least 1 metre from the edge
If your building is listed or in a conservation area, you’ll likely need planning permission. Always check with your local council before starting work.
Grid Connection Considerations
Connecting your solar system to the grid requires approval from your Distribution Network Operator (DNO). You’ll need to inform them of your plans before installation starts.
For systems under 3.68 kW per phase, you can usually use a ‘fit and inform’ process. Larger systems need pre-approval from the DNO. This can take 4-8 weeks, so plan ahead.
You’ll also need:
- MCS certification for your installer
- G99 application for systems over 3.68 kW per phase
- Export meter for selling excess power back to the grid
Working with a certified commercial solar panel installation service can help you navigate these requirements smoothly.
