Location: Junction boxes for solar panels are located on the back of solar panels and are exposed to outdoor conditions, while regular junction boxes are found in walls, ceilings, floors, or any location requiring safe electrical connections.
The junction box shields the electrical connections from environmental factors such as moisture, dust, and temperature fluctuations, ensuring the longevity and reliability of the system. Many junction boxes contain bypass diodes, which help maintain the efficiency of the solar panel by allowing current to flow around shaded or damaged cells.
The main function of a photovoltaic junction box is to connect the photovoltaic panel and the load, which usually leads out the PV (photovoltaic) generated current, thus generating power. First, the solar cell produces direct current (DC) electricity when exposed to sunlight.
Regarding the type of PV junction box for solar panels, junction boxes are usually more affordable. In contrast, advanced models like smart junction boxes with additional features are likely to be more expensive, costing as much as $2000 depending on the quality and brand.
The installer should conform to all the safety precautions listed in this guide when installing the module. Local codes should also be followed in such installations. Before installing a solar photovoltaic system, the installer should become familiar with the mechanical and electrical requirement for such a system.
Place module face down on a soft, flat surface Insert a 3mm flat screwdriver into the slot on the junction box cover. (The cover has a sign of screwdriver). Gently pull up the four slots until the cover been opened.
