Step 5 · Rinse Thoroughly

Once you have scrubbed all sections of the solar panels, it's essential to rinse them completely. Use your garden hose with a gentle spray to rinse from top to bottom. Pay close attention to ensure all traces of soap residue are washed away. Soap left on the panels can create a film that attracts dirt and may reduce the panels' ability to absorb sunlight, thus impacting their performance.
