Half-cell solar modules have solar cells that are cut in half, which improves the Solar Module`s performance and durability. Traditional 60-cell and 72-cell solar panels will have 120 half-cut cells and 144 half-cut cells, respectively. When solar cells are halved, their current is also halved, so resistive losses are lowered and the solar cells can produce more power.
Smaller cells experience reduced mechanical stresses, reaching a decreased opportunity for cracking. Half cut cell PV modules have higher output ratings and are more reliable than conventional solar panels.

1. Device interface 
External signal sources include: set-top boxes, DVDs, PCs, XBOX game consoles, etc. You can connect to an external device via the AV (AV1 or AV2) or HDMI (HDMI1, HDMI2, or HDMI3) interface. The connection is as follows: Connect through the AV interface. As shown in the figure below, you need to use a three-prong cable, yellow for the video signal and red for the right. Channel signal, white is the left channel signal. 
1 If the channel currently broadcast by the TV is AV (AV1 or AV2), the currently playing video signal (yellow line) and audio signals (red and white lines) can be output to other display and audio devices via the AV OUT connector.
2 If the channel currently being played by the TV is HDMI (HDM1, HDMI2, or HDMI3), the AVOUT interface has no video signal output and only the audio signal is output. Audio signals (red and white lines) can be output to audio equipment.
