Cleaning Solar Panels On A Pitched Roof: Step-By-Step Guide
Here is the step-by-step guide to clean solar panels on a pitched roof:
Necessary Equipment:
- Soft-bristled brush: Specifically designed for solar panels to avoid scratching.
- Microfiber cloths: Gentle and absorbent, minimizing the risk of surface damage.
- Sponge: For gentle scrubbing.
- Garden hose with a spray nozzle: A gentle spray is sufficient. Avoid high-pressure washers.
- Bucket: For mixing cleaning solution.
- Mild detergent: Use a small amount of a biodegradable, non-abrasive dish soap.
- Distilled water: For rinsing, to prevent mineral deposits.
- Extendable brush or wand: For reaching hard-to-reach areas.
- Squeegee: To efficiently remove excess water.
- Safety harness and lifeline: Essential for working on steep roofs.
- Sturdy, slip-resistant shoes: For secure footing.
- Gloves: For hand protection.
Cleaning Procedure:
Step 01. Safety First:
- Power Down: Always switch off the main breaker to the solar system to prevent electrical shock.
- Safety Gear: Wear sturdy shoes, gloves, and a safety harness if working on a steep roof.
- Timing: Avoid cleaning during extreme heat, which can cause discomfort and potential damage to the panels. Early morning or late evening provides cooler temperatures and better visibility.
Step 02. Inspection:
- Visual Check: Thoroughly inspect the panels for any signs of damage: cracks, broken glass, loose wires, or hotspots.
- Debris Removal: Promptly remove bird droppings, as they can corrode the panel surface.
Step 03. Rinsing:
- Gently Spray: Use the hose with a spray nozzle to gently rinse the panels from top to bottom to remove loose dirt and debris.
- Cleaning:
- Prepare Solution: Mix a small amount of biodegradable detergent with warm water in the bucket.
- Apply Solution: Dip the brush, sponge, or cloth into the soapy water solution.
- Gentle Scrubbing: Work in small sections, using gentle, circular motions. Avoid excessive pressure.
Step 04. Thorough Rinsing:
- Rinse Completely: Use the hose to thoroughly rinse off all soap residue. Ensure no soap remains on the panels, as it can trap dirt and reduce efficiency.
- Drying:
- Squeegee: Use a squeegee to remove most of the water.
- Air Dry: Allow the panels to air dry completely in the sun.

Important Precautions:
- Avoid Harsh Chemicals: Never use abrasive cleaners, solvents, or bleach on solar panels. These can damage the anti-reflective coating and significantly reduce their efficiency.
- Professional Assistance: If you are uncomfortable working on a roof or if the panels are heavily soiled or damaged, consider hiring a professional solar panel cleaning service.
- Warranty Review: Review your solar panel warranty to ensure your cleaning methods won’t void the coverage.
Regular Maintenance:
- Frequency: Clean your solar panels every 3-6 months for optimal performance.
- Increased Cleaning: If you reside in a dusty area or near industrial sites, more frequent cleaning may be necessary.
By following these steps and prioritizing safety, you can effectively clean your solar panels and ensure they continue to generate maximum power for years to come.
This guide provides a comprehensive and safe approach to cleaning solar panels on pitched roofs, contributing to the long-term efficiency and sustainability of your solar energy system.
Why Cleaning Of Solar Panels Is Necessary?
Cleaning solar panels is essential for several reasons that directly impact their performance and your overall energy savings:
- Reduced Sunlight Absorption: Dust, dirt, pollen, and bird droppings accumulate on the panel surface, creating a barrier that obstructs sunlight. This significantly reduces the amount of sunlight reaching the photovoltaic cells, hindering energy production.
- Diminished Power Output: With less sunlight reaching the cells, the panels generate less electricity. This increased reliance on grid power translates to higher energy bills.
- Accelerated Panel Degradation: Prolonged exposure to dirt and debris, particularly corrosive substances like bird droppings, can damage the panel’s surface. This accelerates wear and tear, potentially shortening the panel’s lifespan and reducing its overall efficiency.
- Potential Safety Risks: Bird droppings can be corrosive and damage the delicate surface of the panels.
- Warranty Considerations: Some solar panel warranties may be voided if proper maintenance, including regular cleaning, is not performed.
