Solar Panel Hot Spots And Delamination Reasons

Melin Sunergy Co.,Ltd | Updated: Aug 09, 2017

  First, the solar panel hot spots and delamination reasons:

  1. Component repair when there is a foreign body in the surface will cause hot spots; 2 welding adhesion is not enough to cause hot spots; 3. delamination temperature, time and other parameters do not meet the standard.

  Second, the impact of components:

  1. Hot spot causes the solar panel power attenuation failure or directly lead to burned out of the components burned; 2. delamination caused by component power attenuation or failure affect the component life to make the components scrapped.

  Third, preventive measures:

  1. Strictly in accordance with the requirements of the repair SOP operation, and pay attention to repair after the inspection Note 5s; 2 soldering iron soldering machine temperature control to meet the standards; 3. Timing check laminator parameters are in line with process requirements, The degree of cross-linking ensures that the degree of cross-linking meets 85% ± 5% of the requirements.

  Monitoring and maintenance of solar panels

  1, to keep the solar cell components square cleaning surface cleaning, such as the accumulation of dust, available clean line duster to clean. If dirt can not afford to clean, you can rinse with water, and then use a clean cloth to dry the water. Do not use solvents with corrosive parts or wipe with hard objects. In case of snow when the time to clean up.

  2, to regularly check the solar panel matrix metal stent corrosion, and regular anti-corrosion treatment of the stent. Square stent to keep ground well.

  3, the use of regular (such as 1 to 2 months) on the solar panel matrix photoelectric parameters and output power to detect, to ensure the normal operation of the battery square.

  4, the use of regular (such as 1 to 2 months) to check the solar panel packaging and connection joints, such as the discovery of open plastic bags, cell disc color and connector loose, off line, corrosion, etc., to timely repair or replace.

  5, with a polar axis automatic tracking system of solar cell square bracket, to regularly check the tracking system of mechanical and electrical performance is normal.
