For measurement of IV curve we connect three series resistances as load and vary the resistance and measure I & V at different points. We can connect three rheostats (variable resistance) in series. first resistance to match 0 to 70% of Voc, second resistance 70 % to 90 % Voc. third resistance 90% to 100 % Voc. This will help in taking more data points to match the curve. Digital voltmeter resolution should be 0.001V (max 0.999V) and digital ampmeter 0.001 A (max 0.999A). This will give good accuracy of readings and is economical. - J N Karamchetti
