following maintenance operations in order to guarantee maximum module performance:
1. Clean the glass surface when required. Use water and a sponge (or a soft cloth). A non‐

theglasstransparency.
2. Clean the modules during the coolest hours of the day to avoid thermal stress and
consequentmechanicalstresswithriskofbreakage..
3. Dirt must never be removed or rubbed when dry to avoid micro‐scratches and a loss of
efficiency.Incaseofsnow,useasoftbrushtocleanthesurfaceofthemodule.
