What is a photovoltaic junction box?

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. A quality PV junction box is certified (e.g. via TÜV) and regulates the heat and offers reliable long-term safety.
