About Precautions for cleaning photovoltaic panels at high altitudes
Clean your solar panels thoroughly and regularly (once or twice a year is usually sufficient). Use clean, cool water, mild cleaning solutions like soapy water, or special solar panel cleaners. Stick to soft, non-abrasive cleaning tools such as microfiber cloths, soft brushes or even just the garden hose. Rinse solar panels thoroughly after .

Step one in cleaning your solar panels is safety. These panels are typically located on rooftops, so ensure you have proper safety gear. If your panels are too high or your roof too steep, consider hiring a professional cleaning service. Before you start cleaning, check your solar panel manufacturer’s guidelines.
Only when exposed to sunlight can solar panels generate electricity. Weather conditions have a significant impact on the frequency with which solar panels require cleaning. Frequent cleansing may be necessary in the presence of smoke, pollen, pollution, debris, and detritus.
High-altitude considerations: CAT III and IV equipment must be used for PV systems at high altitudes because air becomes less insulating and less dense as you go up, which decreases its cooling ability. This means the breakdown voltage—the minimum voltage causing an insulator to become electrically conductive—decreases with altitude.
The tools needed to properly clean photovoltaic panels. To clean the surface of the panels, all you need is soft, lukewarm water and a non-abrasive sponge. Nothing more. Please be aware that applying cold water to a warm panel could result in thermal shock, thereby damaging your panel.

6 FAQs about [Precautions for cleaning photovoltaic panels at high altitudes]
Should you clean solar panels without feet firmly planted?
Never clean solar panels without your feet firmly planted on a stable surface. While cleaning, it's crucial to avoid damaging any electrical components, as this could make the solar panels less effective or disrupt their operation altogether. Always weigh the safety risks and benefits before cleaning your solar panels.
Which cleaning technique is best for solar PV panels?
The TOPSIS method is employed to compare the cleaning techniques and rank them from most favored to least favored. Manual cleaning of the PV panels is the highest ranked cleaning technique according to the TOPSIS ranking. The efficiency and power output of photovoltaic (PV) panels are vital to the solar PV plant.
Do PV panels need to be cleaned?
In some cases, however, dust particles and soiling on the PV panel pose a real challenge to clean, as in many cases cleaning would lead to possible damage to the surface of the PV panel . Also, many cleaning techniques rely on water to clean PV panels, which may lead to inefficient usage of water supply and waste.
Do solar panels need to be cleaned after a downpour?
Whether you have a rigid rooftop array or a series of portable solar panels, it’s best to keep cleaning to a bare minimum. While rooftop panels should be fine after a downpour, call a cleaning service if in doubt. For your portable panels, keep it simple with water, and a soft cloth.
How to prevent negative environmental impact on solar panels?
The optimal way to prevent negative environmental impact on solar panels is to apply proper periodic cleaning and mitigation methods, which will ensure high efficiency and productivity of the cells .
How often should PV panels be cleaned?
Meanwhile, the PV panels, kept uncleaned for 20 days and 30 days produced 5% and 7% less power, respectively. However, it was found that cleaning the panels after 15 days is the most feasible cleaning frequency; the losses were brought down to 4%. Hammad et al. [ 155] proposed a calculated cleaning frequency of 12–15 days for PV panels in Jordan.
