Solar panels work by using sunlight to create electricity. Over time, dust, dirt, and other debris can build up on the panels and reduce their ability to absorb sunlight. This can decrease the amount of electricity they generate and lead to overheating.

Even if a small amount of dirt or debris is blocking the sunlight, it can significantly impact the performance of your solar panels. That’s why it’s essential to keep them clean and free of debris!

Before you start cleaning solar panels, it’s important to gather the right tools and supplies. You will need:

  • A soft brush (like a bristle brush)
  • A hose with a spray nozzle
  • A ladder (if the panels are not easily accessible)
  • A bucket
  • Mild soap
  • A towel or cloth

Once you have all the supplies, you’re ready to start cleaning!

How to Clean Solar Panels

Cleaning solar panels is a pretty simple process. Just follow these steps:

1. Use the Soft Brush to Dislodge any dust, dirt, or leaves.

Starting by dislodging debris and dirt is the best approach because mixing the dust with water can cause a muddy mess.

Use the soft brush to lightly brush away any dust, dirt, or leaves on the solar panel.

Once you’ve removed all the debris, you can move on to step 2.

2. Use the Hose to Rinse Away any Remaining Dirt or Debris

After most of the dirt and debris has been removed, you can use the hose to rinse away any remaining residue.

Be sure to use a hose with a spray nozzle to control the pressure of the water.

Once you’ve rinsed the panel, move on to the next step.

3. Use the Mild Soap to Clean the Solar Panel

Mix together some mild soap and water in a bucket, then give the panels a good cleaning with the soft brush.

Be sure to rinse the panel thoroughly afterward to remove any soap residue, then use a soft cloth or towel to wipe away the soap and water.

How often should solar panels be cleaned?

Solar panels should be cleaned at least once every six months, but more often if they are located in an area with dust or pollen. If you live in an area with heavy rainfalls, you may also want to clean the panels more frequently to prevent build-up.

Can solar panels be damaged by water or cleaning products?

Solar panels are designed to withstand harsh weather conditions, but it’s still important to use caution when cleaning them. Avoid high-pressure water on the panels, as this can damage the sealant and let water inside the panel.

It’s also important to avoid harsh chemicals or solvents on the panels, as they can damage the surface. Instead, stick to mild soap and water for the best results.

Can you walk on solar panels?

Solar panels are pretty durable and can withstand a lot of weight, but it’s still best to avoid walking on them, especially when cleaning them, as they can be very slippery.
