Solar panels are quickly becoming the latest house craze, and for good reason. These trendy solar cells are able to save you money while also protecting the environment. However you may have noticed that your once pristine panels are now completely covered in dirt. How could this happen? Read on to find out why.
What They’re Made Of
To understand why your solar panels seem dirty, first you should know what they’re made of.
