Solar Panel Maintenance Guide

Step 1: Safety First

• Turn off the system if possible (check your inverter manual)
• Use a stable ladder or access equipment
• Wear non-slip shoes and safety harness if on roof
• Work early morning or evening when panels are cool

Step 2: Rinse with Water

Use a garden hose with a soft spray (not high pressure) to rinse off loose dirt and debris. Start from the top and work down to avoid streaking.

Step 3: Gentle Scrubbing (if needed)

For stubborn dirt, use a soft sponge or microfiber cloth with soapy water (mild dish soap). Never use abrasive materials, harsh chemicals, or metal tools that could scratch the glass.

Step 4: Rinse and Dry

Rinse thoroughly with clean water and let panels air dry. Avoid using squeegees on hot panels as they can leave streaks.

Snow Removal

Generally, you don't need to remove snow - it usually slides off on its own. However:

• If snow persists for days, gently brush off with a soft broom
• Never use metal tools or shovels
• Don't walk on panels to remove snow
• Let panels warm up in sunlight first (snow slides easier)

Cold Weather Performance

Solar panels actually perform better in cold weather (panels are more efficient when cool). However, shorter days and snow cover reduce overall winter production by 30-50% compared to summer.
