To safely clean solar panels

 To safely clean solar panels, turn off the system first and avoid doing it during the hottest part of the day. Use soft cloths or brushes with low-pressure water and avoid abrasive materials, harsh chemicals, or high-pressure washers. On rooftops, prioritize safety by using fall protection and stable ladders, or hire a professional. 

Before you begin

Shut off the system: Turn off the solar panel system before starting any cleaning to avoid electric shock.

Time it right: Clean early in the morning or late in the afternoon when panels are cool to prevent thermal shock to the glass from rapid temperature changes.

Wear proper gear: Use gripper footwear, wear safety goggles and hand gloves, and use a ladder with a spotter if necessary. 

Cleaning process

Rinse gently: Use low-pressure water to rinse off loose dirt and dust. Avoid high-pressure washers.

Use soft tools: Clean with a soft cloth, sponge, or a brush with soft bristles. Never use abrasive scrub pads or hard brushes.

Use mild cleaning solutions: For stubborn dirt, use a mild, non-acidic, non-abrasive detergent mixed with water. Avoid harsh chemicals, detergents, or abrasive cleaners.

Wipe carefully: Use light pressure and gentle, circular motions. Avoid forceful scrubbing.

Rinse thoroughly: Make sure to rinse off all cleaning solution to prevent residue from drying and causing spots.

Remove water: If possible, use a squeegee to remove excess water to prevent water spots, especially if using tap water. 

What to avoid

Do not stand or lean on the panels, as this can damage them.

Do not use high-pressure washers.

Do not use abrasive tools, chemicals, or strong detergents.

Do not clean panels that are hot, cracked, or have a perforated back.

Do not use hard water, as the mineral content can leave deposits. Use soft, deionized, or distilled water if possible.
