In different types of solar panels designs, both the bypass and blocking diodes are included by the manufactures for protection, reliable and smooth operation. We will discus both blocking and bypass diodes in solar panels with working and circuit diagrams in details below.
When connecting diodes, it's important to ensure the cathode is connected to the positive terminal of the solar panel and the anode is connected to the negative terminal of the solar panel. In case you do the opposite, the current will be blocked, and your solar panel won’t work. To connect the diodes, you need the following tools:
Diodes also improve the efficiency of your solar power system. By allowing the current to bypass the shaded areas of the solar panel, diodes help you get more power from your solar panels. This is because instead of losing the power that would've been wasted in the shaded areas, the diode will allow it to flow through itself.
For solar applications, you need a 3-8 amp diode. The size you choose depends on several factors, including: The size of your solar system: The size of your solar system is the primary factor in determining what size diode you need. If you have a large solar system, you will need a larger diode to handle the increased current.
When one solar cell of the panel is shaded while the others are illuminated, a hot spot could appear and leads to the shaded cell destruction. The bypass diode is an efficient solution to eliminate the “hot spot” and maintain the current delivery. The Schottky diode is a cost effective candidate.
For example, if you're using a 12-volt solar panel to charge a 12-volt battery, you'll need a diode with a reverse voltage of 24 volts. The reverse voltage determines the amount of power that can be dissipated by the diode. If you're working with high voltages, you'll need to choose a diode with a higher reverse voltage.
