A new outdoor photovoltaic (PV) module test platform was introduced to measure I–V characteristic curve of PV module in this study. The proposed test platform was designed centring on the programmable electronic load (E‐load) which used the transfer characteristics of metal–oxide–semiconductor field‐effect transistor (MOSFET) and controlled PV module output current by controlling the drain current I D of MOSFET indirectly. Ultimately, controlling the PV module work on any operating point of the I–V curve. This test platform can automatically shift operation mode contraposing the I–V curve of PV module. It can continuously measure I–V curves and ambient data in the outdoors including the total irradiance, temperature of PV module back sheet and ambient temperature. The test results show the proposed test platform's accuracy meets the user's requirements, and more details of I–V curve can be obtained than by using traditional measurement mode.
