What is the difference between a diode and a solar panel?

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.

What are the different types of diodes in a solar electric system?

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.

Which diodes are used as bypass diode in solar panels?

There are two types of diodes are used as bypass diode in solar panels which are PN-Junction diode and Schottky diode (also known as Schottky barrier diode) with a wide range of current rating. The Schottky diode has lower forward voltage drop of 0.4V as compared to normal silicon PN-Junction diode which is 0.7V.

Why do solar panels have diodes?

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.

Do solar panels have blocking diodes?
