A method for conditioning a photovoltaic module for testing includes setting an effective irradiance of a continuous light source at a target plane, configuring a test photovoltaic module to operate at a substantially maximum power point configuration, positioning the test photovoltaic module adjacent to the target plane, and configuring the test photovoltaic module for testing by removing the light source, cooling the test module to a testing temperature, and reversing the substantially maximum power point configuration.

Solar module test control

In one aspect of the invention, a semiconductor die includes a plurality of resistive elements operable to receive a voltage differential between at least two of the resistive elements. The semiconductor die also includes a test circuit coupled to at least three tap points along the resistive elements. The test circuit is operable to measure a voltage at at least two of the tap points. A difference in the voltages between the at least two tap points is proportional to a resistance of the one or more resistive elements between the at least two tap points.
