If your solar panels are full of dust, dirt, or grime, your system’s output may be significantly decreased. It reduces the efficiency of the sun by blocking it.
Trying to clean solar panels: a step-by-step guide
It’s best to keep your solar panels relatively clean and free of debris to get the full pay benefit of solar power.
Switch off your device completely.
DC systems will have to be switched off completely. The Solar Supply Main Switch also should be used to turn off any AC systems.
Any rainwater collection or gutters should be disconnected or blocked.
If you have rainwater tanks installed and connected to your guttering system, have them temporarily disconnected or shut off from the gutters so that no dirty water runs into your tank.
Choose a time of day that is cool and mild.
The confluence of hot glass on your panels and cold water can increase the risk of cracking due to a temperature change. If you can’t clean your solar panels in the morning, an overcast day or a mild, cool evening will work just fine.
Clean your panels from the ground.
Clean your panels from the ground for safety reasons. Direct water onto your panels with a hose.
Water should only be directed onto the tops of your solar panels.
While some water should contact the back of your panels, you should not direct water onto the back of your panels or into the gap between your panels and your roof.
Final Note
- Any accumulated dirt and debris can be washed away with a bar of simple, mild soap and water.
- Firstly, check the manufacturer’s instructions or operating manual to recommend cleaning fluids or materials to use.
- However, cleaning your solar panels in late spring and late autumn is a good idea.
