Shading and Solar Panel Cleaning

Shading can significantly reduce solar production, even when only a small section of the array is affected.

Common causes include:

• Trees and new vegetation growth
• Buildings or structures
• Antennas and roof equipment
• Leaves, bird droppings or debris
• Dirt and dust buildup

Solar panels normally require little maintenance, but cleaning may help where dirt, salt, dust or bird droppings have built up.

Cleaning Solar Panels

• Clean only when it is safe to do so.
• Use clean water and a soft brush or cloth.
• Avoid abrasive cleaners, pressure washers and harsh chemicals.
• Do not walk on the panels.
• Do not climb onto a roof without suitable equipment and training.

Rain may clean light dust, but heavier buildup may require professional cleaning.

Contact MyEnergy if shading has increased, panels are damaged or production remains low after cleaning.

Record what has changed

From a safe position on the ground, note whether shading affects the array at particular times and whether nearby vegetation or structures have changed. Record the weather and time when production appears low. Photos taken without climbing or reaching across electrical equipment can help the support team assess the situation. If safe access is not available, arrange professional advice instead of attempting cleaning yourself.
