Common factors affecting solar productivity – bird droppings, dust, leaves, shade. Panel maintenance is necessary as dust accumulation affects panel performance.
Does dust affect solar panels? The short answer is yes!
The biggest factors contributing to dust formation are geographic location and surrounding elements that can contaminate the system. Heavy rain can help clean and remove dirt and contaminants from panels, but as some smaller studies suggest, most major studies show that dust build-up can kill a system in as little as a minute. Reported that it can reduce the efficiency of the Studies show that properly maintained solar panels are 3.5% more efficient. The daily energy loss for one year due to dust adhering to the solar module surface is about 4.4%.
Photovoltaic systems installed in areas prone to dust generation, such as near major roads or farmlands, require more frequent and thorough maintenance. Failure to remove dust from panels installed in such locations can adversely affect solar power generation.
Bird droppings are the biggest threat!
Bird droppings can affect panel performance more than dust accumulation. Traditional string inverter PV systems may produce little or no energy if bird droppings cover some or all of the solar panels.
Trees near panels not only shed leaves and branches but also attract birds. Over time, these cause bird droppings and dirt that not only need to be cleaned and removed but also pose a safety risk. This necessitates monthly or yearly gutter cleaning and bird screening. You might. Most homeowners prefer DIY solar panel maintenance. If you use this approach, remember to follow safety guidelines to safely clean your solar panels and gutters.
How do you clean solar panels at home?
If you want to self-clean, we recommend choosing clean soft water (do not use salt/hard water on the panel), detergent, and a good soft brush when applying soapy water. If any part of the panel needs further cleaning, use only mild detergents. Use a sponge covered with mild soap and a cloth to safely and thoroughly wipe the soiled area. This will prevent damage to your records from harsh chemicals.
