Obtain any required local permits and approvals before installation. Many municipalities require specific permits for solar systems, which might include electrical, structural, and zoning approvals.
Clear any obstructions from the roof or ground area where the panels will be installed.
For roof-mounted systems, install racking or mounting brackets directly onto the roof. This involves drilling holes and securely anchoring the mounts to ensure the panels stay in place under various weather conditions.
For ground-mounted systems, set up a frame in a designated area, usually involving posts that are cemented into the ground to secure the panels.
Attach solar panels to the mounting structure, securing them in place with bolts or clamps. The angle of the panels is typically set to optimize sun exposure based on location, though some systems have adjustable or tracking mounts to follow the sun’s movement.
Connect the panels in series or parallel, depending on the design. Proper wiring ensures that the system operates at the correct voltage and current.
Install wiring to connect the solar array to the inverter(s), ensuring the cables are weatherproof and protected from wear.
Install the inverter(s), either near the array (for microinverters) or in a central location (for string or central inverters). The inverter converts DC power from the panels to AC power for home or grid use.
If the system includes battery storage, connect the inverter to the battery bank. Batteries store excess power for later use, offering backup power and enabling off-grid capabilities.
Connect the inverter to your electrical panel (breaker box), allowing solar power to flow through the building’s wiring.
Install a production meter if required by the utility company to track the amount of energy generated.
Verify that the system operates correctly by checking voltage and current, inverter functionality, and proper grounding.
Local authorities or utility representatives may need to inspect the installation to ensure it meets code requirements and safety standards.
Once approved, activate the system to start generating solar energy.
Set up a monitoring system (often included with inverters) to track energy production, detect any issues, and optimize performance.
