Welcome to the MismatchLossStudy wiki!

Factors contributing to System Level Mismatch Loss

Implemented

• Manufacturing variability

Future scope

• Shading
• Non-uniformsoiling
• Operating temperature non-uniformity
• Varying DC wiring lengths
• Uneven degradation

What is PVMismatch?

• Core framework for the study
• An explicit IV curve calculator
• Written in Python
• Go Open Source! (https://github.com/SunPower/PVMismatch)
• PVMismatch Model chain
• Cell > Cell string > Module > String > System
• set ”Suns” and temperature for each cell
• configure cell string layout and bypass diodes
