Grace Solar associated with manufacturing half-cut solar panel of ADANI SOLAR with a firm commitment to quality. Half cut cell modules have solar cells that are cut in half, which upgrade the module’s performance and durability.
Traditional in solar panel have 60- and 72-cell panels but in half cut solar module have 120 and 144 half-cut cells, respectively. When solar cells are halved, their current is also halved, so resistive losses are lowered and the cells can produce a little more power. Smaller cells reduced mechanical stresses, so there is a decreased opportunity for cracking & losses. Half-cell modules have higher output ratings and are more reliable than traditional panels.
Thus half-cut cells divides the internal current in the system and ameliorate its performance, longevity and shade tolerance. And the results becomes - power loss is proportional to current, half-cut solar panels reduce the power loss by a factor of 4 which increases the power output.
Basically, in solar panel the resistive power losses occur when electrical current passed through the cell interconnection. While these solar cells cut in half, the current is divided. This decreased current in turns lower resistive losses and improves the performance. This cut cell solar module design claims to increase the output by 2.5% over a full sized cell and 9 to 10 W per panel.
This half cut solar panels have six string design over the three string design of traditional one, hence is more resistance to the effects of partial shade on the panel. So when there is any partial shade on a panel, because of any leaves, branches, bird poop or dust/ debris, the shaded area will only affect a sixth of the entire panel power output, rather than one third of the output.
The six string design mitigates the cells size this in turns reduce the stress on each cell interconnection expansion and contraction as the panel heats and cools each day. Further, the small cell size bends less, hence less prone to cracking as well as it also slash downs the hot spot temperature, which ultimately lowers the risk of damaging the panel.
