Traditional concentrator photovoltaics (CPV) systems cannot capture diffuse light and require bulky suntracking. In this work, we characterize a commercially oriented, semi-transmissive, micro-CPV with integrated tracking optically, thermally, and electrically under the sand-laden, hot desert climate of Abu Dhabi, United Arab Emirates to evaluate its potential for agrivoltaics and ability to contribute towards the interplay of the foodenergy nexus. When the module operates in an "Electricity" mode (E-mode) by focusing direct light on microcells, the peak electrical efficiency was 26.9 % while 14-26 % of the incoming irradiance was uniformly transmitted as diffuse light underneath. When climate conditions are not favourable for electric generation, switching to a "Maximum Light Transmission" mode (MLT-mode) yielded a transmittance up to 71.61 %, providing a daily illuminance (daylighting applications) of 1.84 x 109 lumens m-2 day-1 and Daily Light Integral (DLI) dose of 29.69 molPAR m-2 day-1, suitable for moderate-to-high light crops. On the thermal front, the air temperature beneath the panel surpasses the ambient temperature by a range of 10-15 degrees C, and the solar cell temperatures ran similar to 27 degrees C above ambient at midday. Based on the data and observations of a 1-year crop-agnostic module characterization, we identify design improvement and manufacturing errors, mostly in the field of optics and tracking-integration.
