Solar Panel Cleaning in Corona

For most homes in Corona, we recommend cleaning your solar panels at least twice a year. The high dust levels, agricultural pollen, and seasonal Santa Ana wind storms in Southern California build up a thick layer of grime that blocks sunlight and degrades your system's performance.

No, rain is rarely sufficient to clean solar panels. Light rain often mixes with accumulated dust to create a muddy film, which actually reduces efficiency further. Furthermore, rain cannot wash away baked-on bird droppings or sticky pollen. Professional cleaning using pure water is required to restore full efficiency.

Never. We use a professional-grade deionized pure water system combined with specialized, non-abrasive solar brushes. Tap water contains minerals that leave hard water spots, and household soaps leave a sticky film that attracts dust even faster. Pure deionized water dries spotless and keeps your panels clean longer.

No. Our cleaning methods fully comply with solar manufacturer guidelines. We do not use any abrasive chemicals or high-pressure washers, which could damage the anti-reflective coating or seal on your panels. Regular professional maintenance actually protects your investment and ensures your warranty remains valid.

Dirty solar panels in Corona typically suffer a 15% to 25% loss in energy production. For an average residential system, this drops monthly energy output and increases your electric bill by $15 to $50+ per month. Keeping them clean ensures you capture maximum utility savings.
