Adding solar panels to your home is an excellent way to reduce your annual electricity costs. However, the upkeep can often be confusing for new users. Use the guide below to learn when your photovoltaic system needs cleaning and how to do so.

How to Determine When Your Solar Panels Need Cleaning

Generally, solar panels require very little maintenance. Regular rainfall is often enough to remove any dirt and debris. However, dry periods can allow bird droppings and tree sap to build up on the panels, which might lower the amount of solar energy they can trap and store. Also, heavy particulates in the air, such as pollen, can potentially land on the panels and prevent them from receiving sunlight. 

Check the condition of your panels every few months. If they are installed on your roof, stay safe by performing your inspection from the ground. Visible dirt accumulation and leaves on your panels will make them less efficient. If you aren’t expecting rain, it’s probably a good idea to have them cleaned to restore their full function.

How to Clean Solar Panels

If your solar panels are located on the ground, they can usually be cleaned with pure water and a sponge or scrub brush covered with a cloth. Use a mild soap to remove tough mud and dirt, and isopropyl alcohol for oily spots. Do not apply detergents, abrasive powders, or harsh cleaners as these might scratch or streak the glass. 

Perform any cleaning early in the morning or late in the afternoon. An overcast day should also be fine. Just make sure to avoid cleaning under direct sunlight, which will cause the water to evaporate and leave behind the soap. Also, if your solar panels are located on your roof, hire a professional service to perform the work to avoid damaging the panels or injuring yourself.
