The Skeleton of a Photovoltaic System

The photovoltaic support system acts as the skeleton of the solar panel, undertaking three main tasks:

Support Structure: Made of aluminum alloy/galvanized steel to adapt to different climates

Angle Adjustment: Adjustable design allows for free tilt angles from 15° to 60°

Wind Resistance Design: Wind pressure resistance must meet or exceed level 8

Rooftop installations require lightning protection grounding components, while ground installations require concrete foundation piles. Special sand-resistant supports are also needed in desert areas.

 

The Neural Network of Current Transmission
The journey of current from the photovoltaic panel to the inverter requires these key components:

DC Cables: Double-layer insulation with UV protection, temperature resistance -40℃ to 90℃

MC4 Connectors: Waterproof rating IP67 or higher, plug-in/plug-out life exceeding 100 cycles

Junction Boxes: Built-in diodes to prevent backflow, heat sink design for 10℃ cooling

It is recommended to check cable aging every 2 years. In humid areas, install moisture-proof sealing rings.

 

Guardians of System Safety

These small components are crucial to the safety of the entire system:

Reverse Diode: Prevents backflow of current at night

Surge Protector: Protects against voltage fluctuations caused by lightning strikes

Monitoring Module: Monitors the power generation of each module in real time

Cleaning Tool: Flexible brush head extends module lifespan
