Sunport Power High Efficiency 385-405W Full Black Solar Panels Uses 400 Watt For Your Home

Full Black

All black design for more elegant applications

High Efficiency

Busbar-free design increases cell conversion efficiency,more power output can be achieved at low irradiance conditions

Lead Free

Eco-friendly PV design achieves lead-free MWT module without soldering materials

High Reliability

Conductive back sheet’s 2D encapsulation avoids welding stress and micro crack, resulting lower degradation under multiple harsh testing conditions

Innovative Layout

Innovative back contact module layout with asymmetric design for higher efficiency power

High ROI

Single-glass modules with global 30-year performance warranty bring higher return on investment.

TECHNOLOGY COMPARISON

Compared with conventional module, MWT modules reduce 3% shaded area with no busbars. MWT module technology replaces string ribbon by conductive back sheet, abandoning strain, micro-crack and results power degradation, greatly improving stability and reliability.

— Structural Feature —

MWT

Positive and negative electrodes are both on the rear side of solar cell

Conventional

Positive and negative electrodes are located on opposite sides of the cell

— Cell Structure —

MWT

Busbar-free design exhibits higher power output by decreasing shading area up to 3 %

Conventional

Conventional design covers more cell surface from the main busbars, therefore the power output is limited

— Module Encapsulation —

Replace conventional soldering with conductive foil and 2D encapsulation structure

Conventional Cells connected by string ribbons
