Introduction

Even small layers of dust, pollen, or bird droppings can reduce solar panel efficiency. If you’ve been running solar for a few years, you might notice dips in winter or spring — cleaning can often restore that lost production.

Step-by-Step Cleaning Guide

Inspect panels: Look for cracks, corrosion, or shading that might affect performance.

• Pick the Right Time: Early morning or late afternoon when panels are cool. Avoid mid-day.
• Gather Simple Tools: Soft brush, sponge, bucket of lukewarm water. Avoid pressure washers.
• Remove Loose Debris: Gently sweep leaves, twigs, and dirt. Check panel edges for buildup if your system is older.
• Rinse & Clean: Lightly rinse and scrub gently. Experienced users might spot mineral deposits that need a soft wipe.
• Inspect Panels: Look for cracks, chips, or shading issues. Long-term users may notice small scratches — normal, but any major damage should be reported.

Additional Tips

• Clean every 3–6 months.
• Rain helps, but stubborn dirt may need manual cleaning.
• Always prioritize safety — never climb alone.
