Commercial Solar Panel Installation Process: What to Expect
Step-by-step guide to the commercial solar panel installation process, from initial survey to final commissioning.
Understanding the installation process helps you plan effectively and minimizes disruption to your business operations. Heres what to expect at each stage.
Stage 1: Site Survey
A detailed site survey assesses your roof condition, structural capacity, electrical infrastructure, and shading. This information determines the optimal system size and design.
Stage 2: System Design
Engineers design your system based on survey data, optimizing panel placement for maximum generation while considering structural loads and electrical requirements.
Stage 3: DNO Application
For systems over 16A per phase, a Distribution Network Operator application is required. This process typically takes 4-8 weeks and may require grid upgrades for larger systems.
Stage 4: Installation
The physical installation typically takes 2-5 days depending on system size. Work can often be scheduled to minimize business disruption, with most activity on the roof.
Stage 5: Commissioning
After installation, the system undergoes testing and commissioning. This includes electrical safety tests, performance verification, and monitoring system setup.
Stage 6: Handover
You receive full documentation including warranties, MCS certificates, electrical certificates, and monitoring system training.
