However, most of the solar panel array already has a built-in bypass and blocking diodes. Nevertheless, you still have to be careful. I hope this article helped you in learning about blocking diodes and how they are necessary for solar panels.
Solar panels consist of solar cells that convert sunlight into electricity through the photovoltaic effect. Mainly, we use two kinds of diodes for effective solar panels – bypass and blocking diodes. You may be wondering, what is the difference? Well, not much.
However, if you have multiple solar panels wired together in series, and you consistently have shading on one or more of the solar panels, wiring a bypass diode in parallel across the shaded panel can prevent the current from being forced back through the shaded panel and cause it to heat and lose power.
There are two purposes of diodes in a solar electric system — bypass diodes and blocking diodes. The same type of diode is generally used for both, a Schottky barrier diode. But how they are wired and what they do is what makes them different. Bypass diodes are used to reduce the power loss of solar panels\’ experience due to shading.
Diodes are extensively used in solar panel installations. Since the prevent backflow of current (unidirectional flow of current), they are used as blocking devices. They are also used as bypass devices to maintain the reliability of the entire solar power system in the event of a solar panel failure.
The diode is wired in parallel with the cells. Because electricity takes the path of least resistance, it\’s easier for the current to go through the diode than through the shaded cells, so it does. This minimizes heat gain and reduces current loss.
