As photovoltaic (PV) energy continues to gain market penetration due to the lower cost of PV modules, attention is shifting to the balance of system. In this paper, a new efficiency evaluation technique based on a usage model that is synthesized from high-temporal operational data of a PV module is investigated, along with a multiobjective design optimization of the dc-dc stage of a module-integrated inverter. The analysis shows that the technique provides more accurate results than the California Energy Commission weighted efficiency method, particularly when other geographic regions of the world are considered.
