INFORMATION
The efficiency of solar panels can drop by twenty percent or more if regular cleaning is neglected. This decline affects energy output and the return on investment in solar technology. Cleaning thus becomes a vital part of maintaining any photovoltaic system.
The cleaning guide below focuses on keeping solar panels in accessible, safe locations. If panels sit on a roof or in a hard-to-reach spot, it may be wise to hire a professional cleaning service to avoid risks.
How to clean solar panels
Before starting, consider several safety and system integrity factors:
- Consult the manufacturer’s manual for special cleaning and maintenance instructions.
- Safety first: Use appropriate safety gear, and if panels are mounted high or in difficult places, hire professionals to perform the cleaning safely.
- Choose a cooler time of day, such as early morning or late afternoon, to avoid heat stress and rapid temperature changes that could damage the panels.
- Use purified or demineralized water to prevent mineral buildup.
- Use a mild cleaner formulated for solar panels if needed.
- Have a soft-bristle brush or a long-handled solar panel cleaner handy.
- A low-pressure sprayer or hose is preferred for rinsing.
- Keep a soft cloth or sponge to avoid scratching the surface.
- Power down the system before cleaning to ensure safety.
- Inspect for damage or wear that may require professional attention.
- Remove leaves, twigs, and large debris that may accumulate on the panels.
- Moisten the surface with water to loosen dirt. Use low-pressure water if available to prevent damage.
- If necessary, apply a mild cleaner with a soft cloth or brush using gentle, circular motions to avoid scratching.
- Rinse thoroughly to remove any cleaner residue.
- Drying is optional, especially if distilled water was used, but a soft cloth can help prevent water spots.
