【Product introduction】

【Product description】

The family solar panel with power range from 330W to 350W is featured with half-cell technology. The high power desity helps to lower the BOS cost and increase ROI of your solar power system.

The half-cell design of the modules offers the advantages of higher power output, better temperature-dependent performance, reduced shading effect on the energy generation, lower risk of hot spot, as well as enhanced tolerance for mechanical loading.

The actual increase in efficiency per manufacturer varies in the range of 1.5-3% efficiency increase, which is significant.

When the area of a solar cell is cut in half, the amount of electrical current that is carried by each busbar is reduced by half as well.

This decrease in electrical resistance within the busbars results in an overall increase in efficiency, especially during times of high irradiance, driven by significantly higher short-circuit current (Isc) and Fill Factor (FF).

Using half cut solar cells requires an additional step in the manufacturing process: the solar cells need to be cut with a laser cutter and are thus broken into two pieces. These half cut solar cells are typically sized 156×78 mm.
