GUIDE FOR CLEANING SOLAR PANELS (2)

2019-07-01


If the panels are dry, before tackling the modules with water, brush off any loose materials first – this will make cleaning easier and faster.
Don’t use metal objects or harsh abrasive products for removing caked on materials. Scratching the glass on a solar panel can affect its performance as scratches will cast shadows.
Given the nature of good quality solar panel glass, clean water and a little scrubbing with a coarse cloth covered sponge or soft brush should remove the most stubborn grime.  Plastic scourers may also be used.
If your mains-supplied water is hard (mineral-rich) and rainwater is available; use that as a final rinse; then squeegee dry. If hard water is all you have, just be sure to squeegee well as mineral-ladened water can form deposits on glass as it dries.
Most of our solar panels have up to 25 years performance guarantee, and it a lifetime expectancy of 40 years is possible.
