Definitions

  • the present invention relates to a solar power polarization preventing device that prevents charge accumulation on the cell surface that occurs during solar power generation by a solar cell.
  • the frame When the power generation module is a P-type crystal silicon cell, the frame is in a high potential state with respect to the power generation module, and when the glass surface of the power generation module is covered with morning dew etc., the insulating glass also becomes in a high potential state. . Then, electrons separated by sunlight are attracted to the high potential frame through the glass that is no longer in an insulating state, and a weak leakage current is generated from the frame to the power generation module. As a result, polarization occurs on the surface of the antireflection film that is formed under the glass and prevents reflection of sunlight, and this polarization is derived from positively accumulated sodium ions or leakage current accumulated on the surface of the antireflection film. Electrons generated by sunlight are recombined with the generated holes.
  • the power generation module string 11 is installed outdoors. When the power generation module 10 receives sunlight and starts generating power, the power generation module string 11 collects its output and outputs DC power to the power conditioner 20. Normally, there is a power generation amount of about 10 kW for home use, and the power conditioner 20 outputs a voltage of 200 to 400V.

It is not intended for voltage transformation, but is used to enable grounding of the power line on the input side of the polarization preventing device 30 as described above by using the insulating transformer unit 70. Therefore, the primary winding number and the secondary winding number of the insulating transformer 70 are basically in a one-to-one relationship.
  • boosting is performed within the input voltage range of the power conditioner 20 by the transformer function due to power loss due to the insulation transformer unit 70 and insufficient power generation due to weather such as cloudy weather.
