Dirty Solar Panels
Dirty solar panels can negatively impact efficiencies by up to 35%! You should clean your panels every 3-6 months, and during that time dust, pollution, or bird poop may accumulate, causing shading on solar cells that interferes with energy production. If you’re located next to a busy and dusty county road, cleaning may need to occur more frequently.
Why You Should Clean Your Solar Panels
Solar panels work by allowing light into the solar cells. The more light that hits a panel, the more power it will generate. Due to the upwards angle of solar panels, they are more prone to bird droppings and a build-up of general dust and dirt that does not wash off with just rain. This reduces the amount of light hitting the panel and reduces its output. As the projected energy figures claimed by solar panel manufacturers and installers are based on the optimum performance of clean solar panels, this build-up of dirt can adversely affect the panel’s ability to meet those projections. So it is important to clean solar panels in order to protect and maintain your investment.
Pure Water Keeps Dirt At Bay
By the time pure water is used on your solar panels, it is free from dirt, chemicals and minerals. It is the residue caused by impurities and detergents that attracts grime to the glass in the first place; so, by using pure water, you can ensure that your solar panels will stay cleaner for longer, without a soapy film attracting dirt and gunk to the glass.
