Cleaning personnel must wear appropriate personal protective equipment (PPE) with electrical insulation during cleaning. Safety shoes, helmets and safety belts are also mandatory in the case of an industrial roof plant. You won't need any specialized equipment to clean your solar panels. A hose, a soft sponge, and a bucket should do the job.
Pressure washers are not recommended, as they can easily damage solar cells. Instead of using soap, spray the panels with diluted white vinegar and then clean them with a sponge. Use a squeegee or soft cloth to remove excess moisture. Others are of the opinion that solar panels should only be rinsed off from time to time if they see a remarkably low solar emission.
In fact, some solar panel manufacturers require you to clean them every six months to keep the warranty valid. Using a soft brush or sponge, clean the section of the solar panel where you applied the cleaning solution. If, on the other hand, you're comfortable cleaning your own solar panels, you can save money by doing it yourself for little to no cost using common household products. In combination with portable power plants, solar panels can prepare your home for outages or power the entire house with solar energy.
In terms of quality, portability and efficiency, choose portable solar panels with IP67 water resistance to ensure that all parts are not damaged by water or rain, such as the Anker 531 solar panel. You can visually inspect the panels for dirt or dust buildup, in which case it's time to clean them. The ideal is to clean the panels when outside temperatures are relatively cold and there is no strong sunlight. Whether you clean the solar panels yourself or hire a professional depends on your comfort level and the size of the installation.
In addition to adequate safety on stairs, what you need is the right tools and materials so that you don't accidentally damage your solar panels with any abrasive element. For example, if there is a sharp decline in power and variables such as sun intensity and cloud cover are normal, you may need to clean the panels. Whether you have a rigid rooftop installation or a series of portable solar panels, it's best to keep cleaning to a minimum. If you feel uncomfortable in any way or aren't sure you can do it safely, don't try this job and instead hire a professional to clean your solar panels.
Using the one-gallon sprayer, apply a thin layer of the cleaning solution to a small section of a solar panel.
