Mounting the Racking System
This phase involves securely attaching the racking system to your roof or ground. It requires careful measurement and drilling to ensure structural integrity and weatherproofing. For more detailed insights into this stage, visit our guide on installing solar panels on roof.
Installing the Solar Panels
Once the racking is secure, the individual solar panels are carefully lifted and clamped onto the rails. Each panel needs to be precisely aligned and securely fastened to prevent movement and damage.
Electrical Wiring & Connections
This is arguably the most critical and complex part of the solar panel setup, requiring skilled electricians. It involves connecting the panels, inverters, disconnects, and ultimately, your main electrical panel. For a deeper dive into the entire system’s electrical integration, refer to our comprehensive article on solar system installation.
- Connecting Panels to Inverters: DC wiring from each panel (or string of panels) is routed to the inverter.
- Grounding: All metallic components of the system must be properly grounded to prevent electrical hazards.
- Connecting Inverters to Main Electrical Panel: The AC output from the inverter is connected to your home’s main service panel (breaker box).
- Adding Disconnect Switches: Required safety devices that allow the system to be completely shut down for maintenance or emergencies.
Battery Installation (If applicable)
For hybrid or off-grid systems, batteries are installed, wired, and connected to the inverter or a dedicated battery charge controller. This setup allows for energy storage and retrieval.
Commercial Solar Panel Setup Note: For commercial solar panel setup projects, these steps are scaled up significantly, often involving large ground-mount arrays or complex rooftop installations on industrial buildings. Project management, logistical planning, and adherence to commercial building codes become even more critical.
The Commissioning Process: Bringing Your System to Life
The final phase of a solar panel setup is commissioning, which officially brings your system online.
Inspections (Local Authority & Utility Company)
Before activation, your system must pass inspections by local building authorities to ensure compliance with codes and safety standards. The utility company will also perform its own inspection to approve the grid connection and install a bi-directional meter (for net metering).
System Activation & Monitoring
Once all inspections are passed and approvals received, your system can be energized! The main disconnects are switched on, and electricity begins flowing. This moment marks the culmination of your solar panel setup journey.
