Outdoor solar lights are a great way to illuminate your yard, garden or patio at night without needing to run electrical wiring. Over time though, dust, dirt, pollen and other debris can build up on the solar panels and surfaces of the lights, reducing their efficiency. Cleaning your solar lights regularly helps them work their best so you can continue enjoying bright, renewable lighting all night long. Follow these simple steps for cleaning outdoor solar lights.
Clean the Solar Panels
The solar panels are the most important part to keep clean. Any dirt, dust or debris that collects on the solar panels will block sunlight from reaching the photovoltaic cells, reducing the amount of energy generated during the day.
To clean the solar panels:
- Use a soft brush or microfiber cloth to gently remove any loose particles. Avoid using anything abrasive that could scratch the panel surface.
- Mix a solution of warm water and a few drops of mild dish soap. Dampen a soft cloth with the solution and gently wipe down the solar panel surface.
- Rinse the panel with clean water and dry thoroughly with a soft towel. Make sure no soap residue remains.
- For tougher dirt or buildup, use an all-natural, biodegradable cleaner formulated for solar panels. Spray on and let sit for 5 minutes before scrubbing and rinsing clean.
Cleaning the solar panels every few weeks will help them operate at peak efficiency.
Clean the Fixtures and Lenses
The fixtures and lenses of the outdoor solar lights also get dirty over time. Grime on the fixtures can make them appear dingy while dirt on the lenses blocks and diffuses the light output.
To clean the fixtures and lenses:
- Wipe down all plastic and metal fixtures with a soft cloth dampened with the same warm water and mild soap solution.
- Use a cotton swab dipped in rubbing alcohol to gently clean the LED lenses. The alcohol will cut through any grease or dirt buildup.
- Rinse everything thoroughly and dry with a soft towel.
This keeps the fixtures looking new and allows the lights to shine bright.
Check the Batteries
While cleaning your solar lights, it’s a good time to check the batteries and electrical connections.
- Make sure the batteries are still correctly installed and connected.
- Check for any corrosion or damage to the battery terminals and contacts. Clean any corrosion with a cotton swab and rubbing alcohol.
- If batteries are no longer holding a charge, they may need to be replaced for the lights to operate at full capacity throughout the night.
Use Rain-Repellent Sprays
To make cleaning easier in the future, apply a transparent rain-repellent spray to the solar panels and lenses. These sprays form an invisible coating that makes water, dust and other debris slide right off the next time it rains or gets wet. Reapply every few months for ongoing protection.
With just a little regular cleaning and care, your outdoor solar lights will continue shining brightly night after night for years to come. The illumination they provide makes yards, gardens and outdoor living areas more usable and enjoyable after the sun goes down.
Frequently Asked Questions About Cleaning Outdoor Solar Lights
How often should I clean my outdoor solar lights?
It’s recommended to clean your outdoor solar lights every 2-4 weeks for optimal performance. Cleaning off any dirt, dust or debris that collects on the solar panels and fixtures ensures your lights are operating as efficiently as possible.
What is the best way to clean solar panels?
Use a soft brush or microfiber cloth to gently brush off loose dirt. Make a cleaning solution of warm water and mild dish soap and wipe panels with a damp cloth. Rinse thoroughly with clean water and dry with a soft towel. Avoid abrasive cleaners or scrubbers that could scratch the panels.
What should I use to clean the plastic fixtures?
Mix warm water and a couple drops of mild dish soap on a soft cloth. Gently wipe down all plastic fixtures to remove dirt and grime. Rinse thoroughly and dry with a towel. Avoid chemical cleaners which may damage the plastic over time.
How do I clean the LED lenses?
Use a clean cotton swab dipped in rubbing alcohol to gently wipe the LED lenses. The alcohol will cut through grease and stuck-on grime. Take care not to scratch the lenses.
Why clean the battery terminals?
Cleaning battery terminals removes any corrosive buildup and ensures a good connection to the lights. Use a cotton swab dipped in rubbing alcohol to gently clean corrosion from terminals and battery contacts.
Should I use any sealants or sprays?
Yes, apply a transparent rain-repellent spray to the solar panels and lenses after cleaning. This seals out moisture and creates a slippery surface so dirt slides off more easily. Reapply every few months.
How can I make my solar lights last longer?
Regular cleaning, checking the batteries and connections, and using sealants/sprays helps solar lights function optimally for years. Place in a spot that gets maximum daily sunlight, and bring lights indoors during extreme weather.
Conclusion
Keeping your outdoor solar lights looking and performing their best requires just a little regular maintenance. Get in the habit of cleaning the solar panels, fixtures, lenses and electrical contacts every few weeks. Use proper cleaning solutions and techniques to remove grime without damaging components. Apply rain-repellent sprays to protect the lights in wet weather. With proper care, your solar lights will continue providing renewable, cost-free lighting to extend the enjoyment of your outdoor space well into the evening hours.
