Key Parameters in Solar Module

a) Power of module are determined by type of wafer, cell size, cell technology

b) Voc – directly impacts the number of modules that can be connected in series per string

c) NMOT/ NOCT – operating temperature – lower the better

d) Temp coefficient – refers to the loss in energy generation as the ambient temperature increases

e) Module size and weight – affects the type/quantity of structures and space utilization and rooftop loading capability

f) Warranty and Power degradation

Using solar cells with the same efficiency but with different spacing will change module dimensions, can affect efficiencies number

Spacing between each cells are optimized for light capture, energy production, and the expansion and contraction of the materials.Each of these parameters are to provide for long-term, reliable performance , especially in high voltage systems using for 1500V modules

• Upv：Depends on the diode parallel series voltage, 210 product is lower than

166, -> lower risk

• Irev: Power loss caused by partial shading mainly depends on cell quality.

Trina Solar greatly reduced the hot-spot risk by strict control on the reverse

current.
