4 MAINTENANCE
Moser Baer Photovoltaic modules require very little maintenance, following is
recommended to ensure optimum performance.
1.
In view of the tilt angle of the PV modules , normal rainfall is sufficient to keep the
module glass surface clean in most weather conditions. However, if dirt build up
becomes excessive, clean the glass surface only with a soft cloth or sponge
using water.
2.
A mild non abrasive cleaning agent can be used for stubborn dirt. Do not use high
pressure water spray or chemicals to clean the module.
3.
In order to ensure proper operation, please check all wiring connections,
condition of the insulation and mechanical connections every six months.
4.
Observe the maintenance instructions of all components used in the systems
such as support frames, inverters, battery and charge controller etc
