To supply home energy needs, solar panels are becoming more common. The electricity they generate is converted into useful electricity by absorbing solar energy. If solar panels are dirty, they are less cost-effective because the amount of energy produced depends on sunlight exposure.
If you decide to clean your solar panels yourself, you may find that some stains, such as bird droppings, are particularly difficult to remove. Due to the high temperature of bird droppings, they can be baked onto the surface of solar panels. A pressure washer is probably the first thing you think of. But obviously, solar panels are not designed to withstand such water pressure. According to research, the best method for cleaning solar panels is low-pressure soft bristle mechanical cleaning. In this article, we will tell you what happens when pressure wash solar panel.
- Paint Damage. The protective coating that protects the metal frame of a solar panel from the environment can peel off under intense pressure. Over time, under enough pressure, they may even begin to separate from the glass panels, exposing them to environmental factors and risking some irreversible damage, such as rust and corrosion. If you want to resell at this time, this damage could reduce the value of the solar panels. Over time, it can also cost you a fortune to repair them and extend their useful life.
- Overspray. Overspray is a potential problem when pressure cleaning solar panels. Pressure washing of roofs as a problematic cleaning technique has slowly been discovered. Almost every roofing material that can be pressure washed has disadvantages. If the water is in the wrong direction, it can shoot water under your roof and damage the outer coating of composite roofs, shingles, and clay roofs, which can last for years. If other cleaning methods are available, these should be used instead of over-spraying when pressure cleaning solar panels.
- Warranty Denied. Most solar panel manufacturers will recommend avoiding high pressure cleaning of solar panels, and for some, doing so can even void their warranties. This is because of the above factors, as well as concerns that high pressure will cause water to penetrate between the glass panels and onto the photovoltaic system, shattering the vacuum seal.
If your solar panels are coated in dust, dirt, or grime, your solar power system's production may decrease in quality. It's vital to keep your solar panels clean and debris-free in order to get the full cost-saving benefits of solar electricity.
