The fill factor is one of the parameters that are used to assess the performance of a solar PV module. Which of the following is true of the fill factor? A higher value is preferred. A lower value is preferred. A 170 W solar PV module has an open circuit voltage of 44.0 V and a short-circuit current of 5.30 A . Estimate its fill factor. A 200 Wp solar PV module sold on the local market has dimensions of 1 m by 1.15 m . Estimate the solar-to-electric efficiency of this module
