13.0 MAINTENANCE

13.1 VISUAL INSPECTION

Mission Solar Energy recommends that PV systems be periodically inspected by the installer or other qualified personnel.

The purpose of the PV system inspection is to ensure that all system components are functioning properly. At a

minimum, this inspection should confirm the following:

• A

ll cables and connector attachments are undamaged and properly secured.

• No sharp objects are in contact with the PV module surfaces.

• PV modules are not shaded by unwanted obstacles and/or foreign material.

• Mounting and grounding components are tightly secured with no corrosion.

• Defects should be addressed immediately.

13.2 CLEANING

• The dust accumulated on the front transparent substrate may reduce the power output, and may even cause

regional hot-spot effect.

• It’s usually not dangerous for the accumulated dust to reduce the sunshine because the light intensity is still

homogeneous and power reduction is not usually obvious.

• When modules are installed, avoid environmental influence factors that cast shadows and cover part or all of the

modules. This includes other modules, system support, bird drops, dust and so on. This debris may distinctly reduce

the power output.

• The cleaning frequency depends on the accumulation frequency and can vary from 6 months to 2 years. Do not use

alkaline, abrasive, alkali or acid materials, detergents, or cleaning solutions to clean the module.

• It is recommended to wipe the glass surface with a wet sponge or soft cloth. Please do not clean the glass with a

cleaning agent which contains acid or alkali.
