Conventional solar panels have the individual cells wired in series so when a part of the solar panel is shaded it can have a significant effect on the level of power output. By configuring the solar cells in shingles, they can be wired in groups and configured in parallel which significantly reduces the losses caused by shading.
The Cortex shingled module is composed of one-sixth laser-cut 158.75mm cells. By splitting cells, the smaller currents will help reduce “Cell to Module” loss, resulting in higher power outputs. No ribbon soldering brings lower internal resistance, enhances overall toughness, reduces the probability of cracking, and avoids the impact of metal corrosion. The busbar-free design also completely avoids the shielding of ribbon, thereby increasing the utilization of sunlight.
Shingled solar panels have no visible circuitry which give them clean simple look providing superior street appeal.
As solar panel technology continues to mature, shingled modules represent the current state-of-the-art in terms performance, reliability and aesthetics.
