Impact of inverter configuration on energy cost of grid-connected photovoltaic systems

Performance enhancement of photovoltaic array through string and central based MPPT system under non-uniform irradiance conditions

“…As results, it has been suggested that different configurations and operation strategies should be further studied and tested in order to reduce the mismatch losses, which is similar to the conclusion in Ref. [15].…”

“…String based MPPT Central based MPPT The economic analysis is not yet sufficiently investigated due to the lack of detailed information about investment and field data of PV plants [15]. On the other hand, the comparison results strongly depend on unpredictable factors such as the amount of solar radiation, clouds, shadows, dirt or other obstructions that effect the amount of power generated.…”

“…On the other hand, the comparison results strongly depend on unpredictable factors such as the amount of solar radiation, clouds, shadows, dirt or other obstructions that effect the amount of power generated. He et al proposed a method to evaluate the impact of inverter configuration on energy cost of grid-connected PV systems under the assumption that uniform operation conditions are ensured and partial shading conditions are avoided during the design and constructions of PV plants [15]. Cellura et al proposed a methodology for assessing energy and economic performances of PV systems in a large urban context [48].…”

“…He et al [15] proposed a method to evaluate and optimize inverter configurations for grid-connected PV systems. String based system means that a single MPPT unit is connected to one string of PV array.…”

Performance of grid-tied PV facilities: A case study based on real data

“…Various studies have been conducted on PV plant performance and its different elements [4][5][6][7]: the influence of PV module technology [8,9], inclination [10,11], inverter and control systems [12], sun-tracker system [13] and wiring [14] have been determined for experimental and real facilities,. They underline the relatively important role of all these elements in overall system performance.…”
