MAINTENANCE AND SERVICING

A photovoltaic system needs practically no maintenance, as the solar modules are cle-

aned by the rain at the recommended minimum angle of 15°. To avoid reductions in yield,

we do, however, recommend carrying out a regular visual check on the module surfaces.

This is especially important when the slope is less than the recommended 15° minimum

angle. Particularly heavy soiling (e.g., leaves) can cause shades which reduce performance

and should therefore be removed. Clean the glass surface with softened, low lime water,

a water-ethanol- or water-isopropanol intermixture and a soft nonabrasive cloth only. In

exceptional cases, a conventional cleaning agent may also be used in the recommended

dose. Do not use aggressive cleaning agents or metal objects, as they can be particularly

damaging to the hardened glass surface. The electric cables should (where accessible) be

checked regularly for damage, corrosion, and firm hold. Pay particular attention to DGUV

regulation 3 and DIN VDE 0105-100.
