Save me automatic measurement system for solar panel

Click For Summary

Discussion Overview

The discussion revolves around the creation of an electronic system for automatically measuring and deriving the IV (current-voltage) and I-P (current-power) characteristics of solar panels, including the identification of the maximum power point on the graphs. Participants are seeking guidance on the necessary components, circuit diagrams, and experimental design for this system.

Discussion Character

  • Technical explanation
  • Homework-related
  • Experimental/applied

Main Points Raised

  • One participant outlines the need for a system that can measure IV and I-P characteristics and display the maximum power point on graphs.
  • The same participant specifies the requirement for a homemade voltage-controlled electronic load that can handle defined current and voltage ranges, with IMAX and VMAX needing to exceed the solar cell's maximum ratings.
  • Another participant emphasizes the importance of designing a good current load and asks for suggestions on components and design approaches.
  • A later reply reiterates the request for guidance on designing the experiment, indicating a need for clarification on previous posts.

Areas of Agreement / Disagreement

Participants appear to share a common goal of developing the measurement system, but there is no consensus on specific components or design strategies, and the discussion remains unresolved regarding the details of the implementation.

Contextual Notes

Participants have not specified the maximum ratings for the solar cell or provided detailed assumptions about the experimental setup, leaving some aspects of the design open to interpretation.

1.I need to create an electronic system that automatically can measure and derive the IV and I-P characteristics (graph) and it must show maximum power point on the graphs.


2.The system must include a homemade voltage controlled electronic load that can load the solar cell with a well defined current of 0 – IMAX at a solar cell voltage of 0 – Vmax.
IMAX and VMAX must be specified by you and must be a bit bigger than the maximum ratings of the solar cell you decide to focus on.



3. I need block and circuit diagram for this.But I don't know which components need for this.Please help me !

Welcome to the PF. We do not do your schoolwork for you, but we can provide hints and ask questions.

How can you make a good current load? What components would you use, and how would you design it? How would you design this experiment?
 
well ,how would I design this experiment? thanks for information :D
