In this .Solar cell type: Monocrystalline Nominal power: 180W Max-power voltage: 20.5V DC Max-power current: 8.79A Open circuit voltage: 24V DC Short circuit current: 9.22A Panel size: 1470 (L) x 665 (W) x 2 (D) mm Panel weight: 3.15kg Termination: 3m of 4mm² dual core solar cable with un-terminated ends Junction box diameter: 30mm Maximum curvature (arch height*): 250mm . The solar panel junction box is a critical component in a photovoltaic (PV) system, responsible for collecting and distributing the electrical current generated by the solar cells. This compact enclosure houses the bypass diodes, which prevent power loss in the event of partial shading, and connects the module’s output to the external circuit
The following figures show their connections in typical junction boxes: Junction Box Proper choice of diodes in solar PV panels: Type of diodes Currently, there are two types of diodes available in the market to be used as bypass diodes in PV panels and arrays: PN-junction silicon diode Schottky barrier diode.
An older type solar panel junction box showing the three serviceable bypass diodes in the middle. Solar panels contain one or more junction boxes mounted on the rear side, which house the bypass diodes and provide a secure connection point for the interconnection cables. Until around 2017, most solar panels were of the standard 60-cell format . If a short ~1ft length of conduit from a rack-mounted junction box to a through-roof fitting like this can be directly supported by the junction box/through-roof fitting without requiring additional roof-mounted supports, this would be preferable to the fall-back option pictured earlier.
Junction box manufacturers have had to get creative with their designs. “On a bifacial panel, you have to position the junction boxes on the edge where you are definitely sure the backside is not shaded,” Rosenkranz said. “When on the edge, the junction box is no longer possible to be a rectangle, it has to be small.”A solar panel junction box is a critical component of any solar energy system, allowing the safe connection between the photovoltaic (PV) panels and the rest of the electrical system.
