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 !
