6 FAQs about [Jingmao Technology Photovoltaic Panel Junction Box]
Why is a junction box important for a solar module?
Junction boxes play a major role in the functionality of a PV module. They ensure that the current from a solar module can flow in the right direction. Defects at the junction box can lead to heat accumulation with harmful consequences for the module. Within the following picture you can have a closer look at such a defect:
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.
What is the cable length of a Jinko junction box?
ox may be damaged.The cable of the junction box is defined as L, as showed below in Figure 11. For Jinko standard full module L is 900/1200mm, the half–cut module L is 145/290mm, and the SWAN bifacial mo ule L is 150/250mm. For customized module, L can be base on your condition. Please take the cable length into consideration before designin
How does junction box design affect thermal diode performance?
The junction box design has a significant impact on the thermal diode performance. When qualified without solar module, the junction box has to meet DIN V VDE V 0126-5:2008 standard requirements. When qualified with its solar module, the standard is EN61215. Figure 6.
What is the difference between Jinko M10 and Canadian Solar?
According to Jinko, this M10 format is compatible with existing junction box designs. Canadian Solar, on the other hand, released primarily large-area solar modules with 210-mm wafers this year.
Why do solar panels have diodes inside a junction box?
“The diode is the gateway that allows an endless stream of power.” If part of a solar panel is shaded, that string will want to consume power, reversing the flow of electricity. Diodes inside the junction box prevent that from happening. There are two different junction box production techniques—soldering/potting and clamping.
