What Are The Effects Of Blocking Solar Panels?
- Jan 10, 2019 -

When the solar panel assembly is blocked, it will induce the bypass protection component in the junction box behind it to start. The DC current of up to 9A in the component string will be instantaneously loaded onto the bypass device, resulting in local current and voltage of the solar module. The product increases, resulting in a local temperature rise on these battery components, which will generate more than 100 degrees of high temperature in the junction box. This phenomenon is called "hot spot effect". This high temperature has little effect on the panel and junction box in a short period of time, but if the shadow effect is not eliminated and exists for a long time, when the hot spot effect reaches a certain level, the solder joint on the component melts and destroys the grid line, resulting in the entire sun. Scrap of battery components. Obviously, the occlusion seriously affects the service life of the junction box and the panel, and seriously affects the power generation and reduces the revenue.
