1. A method for logging current-voltage data characteristics of the operation of an array of solar cells between open-circuit and short-circuit load conditions comprising the steps ofcontrolling load current in one mode while voltage is measured from open circuit to at least halfway into the knee of the curve where the percentage change in voltage is equal to or greater than the percentage change in current, andcontrolling the load voltage in a second mode while current is measured from the lowest load voltage possible to at least halfway into the knee of the curve where the percentage change in current is equal to or greater than the percentage change in voltage.
