Smartwire connection technology
Higher module power output
Increased module power performance of up to 6%
compared to 3-busbar technology
Dense contact matrix connecting points on the solar cell
Less electrical resistivity and thus less power dissipation
Less impact from optical shading
Improved light reflection with round SWCT wire design.
Higher tolerance to cell micro cracks
Elimination of busbar printing increases solar cell active area
Less silver consumption in cell production
Solar cells connected with SWCT can achieve a reduction up to 83% of silver consumption in cell production
No front busbars, no silver pads on the back-side
Multiple wires allow thinner and more resistive fingers with lower aspect ratios
Bifacial technology compatible
Reliable modules with higher energyyield
Successful IEC and UL certification tests (extended damp heat and thermal cycling passed)
Reduced stress on the wafer as bonding of wires takes place at temperatures below 160°C
Long lasting PV modules enabled with low water absorption encapsulation materials
Gain in energy yield of over 15% under outdoor conditions
Bi-facial SWCT modules show an increased energy yield in terms of kWh/Wp under real outdoor conditions compared with mono-facial modules.
More energy on smaller systems at lower BOS investment costs
