DIY portable I-V Curve Tracer: FAST

Introduction

• a fundamental method to for characterizing solar PV module behaviour
• plots the relationship between current (I) and voltage (V) across the module under varying conditions
• cost-effective portable DIY design

Purpose of I-V Curve Tracer

• Performance evaluation
• Quality Assurance
• Fault detection

System Description

• three versions
  • EMR
  • SSR
  • Cell

Assembly Instructions

Operating Conditions

• PV modules are subjected to different levels of sunlight or simulated conditions
• Current and voltage measurements are taken at each condition to plot the I-V curve
• Analysis of the curve provides information on parameters like maximum power point (MPP), fill factor, and overall performance

Testing Procedure

• indoor/outdoor
• good / broken modules
