Can I use dish soap or detergent to clean solar panels?

While soap and dish detergent might seem logical, they are not suitable for cleaning solar panels.

Why not use regular soap?

  • It leaves behind greasy residues that actually attract dirt.

  • It can damage the coating of the solar panels.

  • It increases the risk of streaks, which reduce efficiency.

What should I use instead?

  • Use demineralized (osmosis) water without any additives.

  • If necessary, use special solar panel cleaning agents approved by the manufacturer.

Conclusion

Avoid household cleaning products. They can do more harm than good to your solar panels.
