28. y within warranty scope It is the user s responsibility to report to the supplier regarding the damages found within 2 weeks 8 1 Cleaning The dust accumulated on the front transparent substrate may reduce the power output and may even cause regional hot spot effect The industrial effluents or bird drops may be serious and the extent of the severity depends on the transparency of the foreign objects It s usually not dangerous for the accumulated dust to reduce the sunshine because the light intensity is still homogeneous and the power reduction is not usually obvious When Modules are working there should not be environmental influence factors to cast shadows and cover part or even all of the Modules such as other Modules system support bird drops and a lot of dust clay or plant and so on these may distinctly reduce the power output JA Solar advises that there should be no obstructed object over the Modules surface at any time The cleaning frequency depends on the accumulated frequency of the fouling In many instances the front surfaces of the Modules will be cleaned with the rain and we can decrease the cleaning frequency 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 8 2 Visual Inspection of Modules Inspect the Modules visually to find whether there are appearance defects the following need particularly special attent
