6 FAQs about [What to do if photovoltaic panels block each other]

Do solar panels need a blocking diode?

If you have multiple parallel strings of solar panels that get shaded at different times, a blocking diode in series will help prevent the power from the sunny string being forced back up through the shaded string. This is common on sailboats, with a solar panel on both the port and the starboard sides.

What should you take care of while working with solar panels?

Moving on, there are some key points you should take care of while working with solar panels. Another important thing is to protect these diodes. For safety purposes, you shouldn’t experiment with the installation of blocking and bypass diodes. It is better to consult a trained professional in this regard.

Can a bypass diode damage a solar panel?

Bypass diodes are used to mitigate the effects of shading, but their failure can exacerbate the issue, leading to potential damage to the solar panels. In this article, we'll delve into the challenges posed by solar panel shading and associated issues with failing bypass diodes.

Do I need a blocking diode?

The most case (99%+), no need a Blocking Diode if do not connect the solar panel on battery directly. The blocking diode is not for block current from the other parallel solar panel. Indeed, a blocking diode will be installed in the charge controller or string inverter. I recently installed some used PV panels on a 24 Volt PV / Inverter system.

What happens if a solar panel is covered by a leaf?

If one cell is covered by a leaf, the second string of solar cells will not produce any current. If there were no bypass diodes, the whole solar panel would produce none or very little current. Thanks to the bypass diodes, the solar panels will still produce 2/3 of it’s rated current.

Why do solar panels need bypass diodes?

This is where bypass diodes make a difference. If you connect these diodes in parallel with the solar panels, they will allow the current from the unshaded panel to flow into them. Other than that, bypass diodes also make sure that the current flowing from unshaded panels doesn’t end up overheating and igniting the shaded panels.
