Commercial solar panels can generate electricity for commercial use. Typically installed on rooftops to maximize sunlight exposure, the installation process involves several steps. Today, in this blog, we’ll take you through a brief step-by-step commercial solar installation process.
A quick installation guide for commercial solar panels
Step 1 - Firstly, mounts are fixed to provide support for the solar panels. The type of mounts used depends on the specific requirements, such as roof-ground or flush mounts. Consideration is given to the panel direction, with the ideal orientation being south for the Northern Hemisphere and north for the Southern Hemisphere. The mounting structure is usually slightly tilted at an angle of 18 to 36 degrees to optimize efficiency.
Step 2 - Next, the solar panels are securely attached to the mounting structure using nuts and bolts. The entire structure is secured for stability and longevity.
Step 3 - The electrical wiring is then done using universal connectors like MC4, allowing compatibility with various panel types. The panels can be arranged and connected parallelly or in a series. Series connection involves connecting the positive wire of one module to the negative wire of another, increasing voltage compatibility with the battery bank. Parallel connection involves connecting the positive terminals and the negative terminals together, maintaining the same voltage across each panel.
Step 4 - The system is connected to a solar inverter, which converts the generated electricity into a usable form. The positive wire from the panels is connected to the positive terminal of the inverter, and the negative wire is connected to the negative terminal.
Step 5 - The solar inverter is connected to a solar battery, with the positive terminal of the battery linked to the positive terminal of the inverter and the negative terminals connected likewise. This battery is crucial for storing backup electricity in off-grid solar systems.
Step 6 - The next step involves connecting the inverter to the grid. A standard plug is used to connect to the main power switchboard. An output wire is then connected to the electrical board that supplies power to the home.
Step 7 - Once all the electrical wiring and connections are completed, the inverter is switched on by turning on the main switch of the home. Most inverters have digital displays showing solar unit generation and usage statistics.
We hope this commercial solar panel installation guide helps you understand the overall process.
