Installing solar panels at a commercial site can feel daunting but knowing what to expect makes the process smoother. From planning to commissioning, here’s a step-by-step guide.
1. Initial Consultation & Site Survey
A solar specialist will assess your building’s energy requirements, roof orientation, and shading. This helps determine the optimal system size and design. Learn more about our commercial solar services.
For more on site assessments, see guidance from Solar Energy UK
2. Design & Planning
During the design phase, your team will:
- Create a panel layout plan and select inverter locations
- Integrate with your building’s electrical system
- Check planning permissions and building regulations
- Carry out the grid connection application and liaison with local DNO (District Network Operator) in accordance with the ENA (Energy Network Association) https://www.energynetworks.org/industry/connecting-to-the-networks/connecting-generation-to-the-electricity-networks
A well-planned design ensures maximum energy generation and compliance. Learn more about UK planning rules for solar installations on the UK Government Planning Portal
3. Installation
On installation day:
- Roof preparation: Safety equipment and scaffolding as needed
- Panel mounting: Panels securely fixed with wiring connected
- Inverter & electrical work: Integration into your building’s electricity system
The installation is typically quick and minimally disruptive when managed by experienced professionals.
4. Testing & Commissioning
Once installed, your system is tested for safety, efficiency, and performance. You’ll receive guidance on monitoring production and managing energy consumption.
5. Ongoing Support
Ablaze offer maintenance, performance monitoring, and warranties to ensure your system continues to operate efficiently for years.
