The solar system comprises monocrystalline, polycrystalline, bifacial, or smart modules, an inverter for DC to AC power conversion, mounting structures, UV/temperature-resistant cabling, and MC4 connectors, all sourced from reputable sources.
Mounting Structure Installation
Solar panels are installed on a solar array using a secure mounting system. The frame is anchored to withstand wind, rain, and temperature changes, and the panels are bolted with precise spacing for optimal sun exposure. The tilt angle is set at the location’s latitude for maximum annual yield. The mounting structure is prepared for stability and durability, with roof-mounted systems using brackets and ground-mounted options using sturdy frames. The structure is then installed according to manufacturer’s specifications, with proper alignment for optimal energy capture. The system provides a solid foundation for the solar cells, ensuring their longevity and performance.
Electrical Wiring and Connection
Solar panels are wired in series or parallel based on voltage and current requirements, using MC4 connectors and weather-resistant conduit. Wiring must follow local electrical standards and include earthing and surge protection. All DC lines feed into the inverter, which connects to the AC electrical panel or energy storage system. Correct wiring is crucial for the system’s functionality, with series connections increasing voltage and parallel setups enhancing amperage. Insulation is essential to avoid short circuits and hazards, and using electrical conduit shields wiring promotes safety and extends installation lifespan. Well-organized wiring facilitates aesthetics and future maintenance.
Testing and Commissioning
Initial testing verifies connections, insulation resistance, and grounding, while performance testing measures voltage, current, and efficiency of panels and inverters.
