Step 2 · Prepare Cleaning Solution

In a bucket, combine a gallon of clean water with a small amount (typically 1-2 tablespoons) of a pH-neutral, biodegradable dish soap or a cleaner specifically designed for solar panels. Stir gently to create a mild, sudsy solution. It is crucial to use only non-abrasive cleaners to prevent scratching the delicate surface of the solar panels. Avoid using detergents with harsh chemicals, ammonia, or abrasive particles, as these can damage the anti-reflective coating and reduce efficiency.
