Techno-Economic-Environmental Impact of Derating Factors on the
Optimally Tilted PV System
Solar-powered photovoltaic (PV) system encounters a signiﬁcant amount of
losses due to different derating factors of PV modules throughout its
lifespan. Thus, proper investigation is much needed to grasp the
technical and economic impact of derating factors on the solar PV
system, specially the one which is connected to the utility grid. This
study performs a comprehensive discussion on various PV loss parameters
followed by a techno-economic-environmental assessment of combined
derating factor on an grid-connected and optimally tilted PV system
located at Hatiya, Bangladesh using HOMER (Hybrid Optimization Model for
Multiple Energy Resources) software. Some criteria linked with derating
factor such as PV degradation and ambient temperature are further
explored to analyze their impact on the aforementioned power system.
Simulation results show that the system provides the best technical
performance concerning annual PV production, power trade with grid, and
renewable fraction with less emissions at a higher value of derating
factor since it represents the lower impact of loss parameters.
Similarly, ﬁnancial performance in terms of net present cost (NPC),
levelized cost of energy (LCOE), and grid power exchange cost is found
lower when derating factor value is higher.
