Cleaning the solar panels is necessary for at least 6 months to maintain efficiency. It is hard to clean solar panels on a pitched roof because of its sloping surface. A pitched roof may be beneficial since it does not let snow pile up on the roof during the snowfall season, but accessing the panels on such a high roof is challenging.
Rain, snowfall, or even dusty winds can cause algae or mold to build up on the panels. These microorganisms can make the tiles slippery and the cleaning process more arduous. So, panel maintenance requires proper safety equipment, extension tools, and gentle cleaning techniques.
On the other hand, cleaning solar panels on a pitched roof requires a process to solve the problems encountered. This blog will walk you through comprehensive steps to clean the solar panel effectively and safely. You can also leave the work to professionals to handle to get the cleaning process done without any risk or hassle.
Why is it necessary to clean solar panels?
With time, dirt, dust, pollen, and bird droppings in polluted areas or containing trees gather on the panels. This can result in just a small amount of debris blocking sunlight, decreasing the system’s energy output.
Research indicates that dirty panels can lose up to 25% of their efficiency. Regular cleaning makes your panel capture as much sunlight as possible, which automatically increases its performance and lifespan.
Tools and Materials Used
To clean a solar panel, you just need a few things that make working a much easier and safer process.
The equipments include
- A sprinkler system or low-pressure watering is required to rinse.
- A soft-bristle brush or sponge is used to work without welcoming any scratch on the panel.
- A telescoping pole that will reach panels from afar to avoid a fall.
- Mild, non-abrasive soap and water for cleaning.
- A squeegee or microfiber cloth for drying.
- A helmet and gloves are safety equipment.
6 Steps to Clean the Solar Panels on a Pitched Roof
Now that you know that cleaning solar panels requires no special equipment, let’s begin the easy process.
- Check Solar Panels
Check the panels for cracks, chips, loose connections, etc. Cleaning impaired panels can make things worse or, at the very least, constitute a safety hazard. Before getting started, consider discussing any issues you detect with a professional who can save you from costly repairs.
- Runoff loose debris
Gently spray the water on the panels with a garden hose or a low-pressure sprayer. This will remove any loose dirt, dust, and leaves and better clean the remaining grime.
Keep in mind that high-pressure washers are not preferable for this step. They are high-strength and can damage the panels or loosen the mounting.
- Clean-in-place preparation
Mix a little mild, non-abrasive soap with water. Avoid using chemical agents and abrasive cleaners, which may damage the solar panel’s protective coating.
- Clean with a Soft Brush or Sponge
Use a telescopic cleaning pole with a soft-bristled brush or sponge to apply soapy water to the panels. If stubborn stains such as bird droppings, algae, and other debris are present, be gentle when scrubbing the surface. Remember not to scratch the surface when cleaning.
- Rinse Thoroughly
The remaining soap residue can lead to streaks, slightly decreasing panel efficiency. That is the reason why rinsing the panels afterward is important.
- Dry the Panels
Drying the panels with a squeegee is not always necessary, but it will remove water spots and leave them looking fresh and professional.
Tips on Cleaning Effectively and Safely
Some safety tips on cleaning the panels can help you or anyone else clean the roof from imposing any danger.
- Clean from a stable position
Clean from a ladder or another stable position rather than standing on the roof.
- Try not to clean after dawn
Sunlight helps the water evaporate faster. So try not to clean during cooler times of the day to avoid the formation of water streaks on the surface of the panels.
- Long handed tools
A long-handled pole, such as a telescoping pole, allows you to clean without climbing directly onto your roof or reaching the edgy area.
- Schedule regular cleaning
In most areas, solar panels need to be cleaned once or twice a year. However, if they are cleaned frequently, they will last a long time, even in dusty or bird-inhabited areas.
- Professional assistance
Hiring a professional cleaning service is safer and more efficient if the roof is too steep or you feel uncomfortable working at a height.
Safety comes first
Safety measures must be implemented before cleaning solar panels on a pitched roof to avoid accidents.
Wear proper safety gear
Wear non-slip shoes and a safety harness to stabilize your steps when working on the roof. Ensure that the ladder is stable and standing on solid ground. It would be much safer to have someone holding the ladder for you.
Check the weather
Avoid cleaning in wet or windy weather, as it may lead to slipping. The best time to clean is during the early morning or late afternoon before dawn when the roof and panels are cooler.
Switch off the system
Always switch off the solar panel system before cleaning to avoid electrical hazards.
Conclusion
To clean solar panels on a pitched roof is one of the most hazardous chores, but it’s manageable if you do it with proper tools and precautions.
When you clean your panel, you make sure they at all times work their best and give off as much energy as you put into them. A professional cleaning service can also help if the issue is of safety or accessibility.
