Passivated Emitter and Rear Contact (PERC) solar cells are modified conventional cells that enable the cells to produce 6 to 12 percent more energy than conventional solar panels. PERC cells have an extra layer within the back side of the cell. This allows some of the sun’s rays to reflect back into the solar cell, giving them another opportunity to be turned into energy.
Shingled modules have no visible busbars and solar cells are cut into five or six strips and connected with an electrically conductive adhesive. The three key advantages of the shingled solar panel design are to produce more power, improve reliability and are aesthetically pleasing.
PERC Solar cells with Shingle Technology
Reinforced frame with aluminum angle
35mm Frame with a support surface of 1.2mm thickness
4mm2 Twin Red / Black Cable to MC4 from Diode Box
More Power : Reduced optical and electrical losses. Shadowing also has less effect due to PERC Shingled Cell design.
Seamless Soldering : Shingled Soldering is a new proprietary Module Encapsulation Technology, achieved using Silver Conductive Adhesive instead of BusBars.
Compact : High efficient cells means smaller modules especially when used in Caravan, RV and Marine applications.
Reduced system cost : High component efficiency reduces floor space, BOS, transportation and operation costs at production level.
Stability : Enhanced reliability and stability. Significantly reduces hot spot effect.
Reliability : Avoids cell crack caused by traditional welding process; the components are flexible and compressible, suitable for a variety of harsh environments.
Performance : 10 year product warranty on materials and workmanship, 25 years linear power output warranty.
