    hi ..
    i have 0.5v solar pannel..i measured that pannel voltage using multimeter directly from solar pannel output terminal....but i cant measure current can i measure..... wat is the procedure to measure that solar pannel current...

    The solar panel can only supply current if there is a load connected to +ve and -ve If you connect your ammeter directly accross the will be measuring the short circuit current and you could damage the solar panel.Connect your ammeter in series with a resistor of at least 100ohms then measure the current.Use Ohms law to calculate the internal resistance of the panel.Then you can use ohms law to calculate the current with any load resistance
