This is an example of how we clean Solar Panels at SMC Cleaning Services. We use a water fed pole with deionized water flowing through it. This is to loosen up the dirt, rinse it off,and leave a spot free clean. Contact SMC Cleaning Services at 281-899-0402 for all of your solar panels cleaning needs in Houston, Tx.
