In a solar farm with 50 PV modules, each PV module is connected to a separate DC/DC converter. The size of every PV module is \( 150 \mathrm{~cm} \times 120 \mathrm{~cm} \). All the DC/DC converters are then connected to a common DC/AC inverter for grid connection. (1) Sketch the electrical configuration of the solar farm. (2) Explain the functionalities of the DC/DC converter and DC/AC inverter, respectively including the role of MPPT. (3) The photovoltaic efficiency of the PV module is \( 25 \% \). The energy conversion efficiencies of the DC/DC converter and the DC/AC inverter are \( 98 \% \) and \( 96 \% \), respectively. Calculate the maximum electrical power output of the solar farm if the sunlight power density absorbed by each PV module is \( 0.85 \mathrm{~kW} / \mathrm{m}^{2} \).
