Solar panel junction box is an important accessory of the solar panels. The junction box is an enclosure on the module where the PV strings are electrically connected. PV junction box is attached with the back of the solar panel (TPT) with silicon adhesive. It wires the (usually) 4 connectors together and is the output interface of the solar panel. A good junction box keeps corrosion at the terminals to a minimum, as it will exclude water coming in. Most photovoltaic junction boxes have diodes. The function of the diodes is to keep the power flow going in one direction, and prevent power from feeding back into the panels when there’s no sunshine. The PV junction box is certified (e.g. via TÜV) and regulates the heat and offers reliable long-term safety. |
