Abstract: This paper presents a detailed analysis of the modified economic method ( F MCE ) for evaluating the performance of photovoltaic module (PV)-enhancing techniques, aiming to address existing research gaps. The impact of influential parameters on the F MCE is examined through illustrative examples. These parameters include the output power of a single solar cell without an enhancer, output power of a PV with an enhancer, manufacturing cost of the PV enhancer, one-watt cost of PV power, and maximum output power of a solar cell with an enhancer equivalent to maximum output power at standard test conditions (STC). The results of this study reveal that the output power of a single solar cell without an enhancer, number of solar cells with an enhancer in the PV, and manufacturing cost of the PV enhancer have a proportional relationship with the F MCE . As these parameters increase, the F MCE also increases, which negatively affects the cost-effectiveness of the PV enhancer, leading to lower performance. So, it is advisable to maintain the values of these parameters at lower levels. Conversely, the output power of a PV with an enhancer and the one-watt cost of PV power exhibit an inverse proportional relationship with the F MCE . As the output power of a PV with an enhancer and the one-watt cost of PV power increase, the F MCE decreases, which positively affects the cost-effectiveness of the PV enhancer, leading to higher performance. Hence, it is recommended to keep these two parameters high for optimal performance. In conclusion, the F MCE may have potential for application by designers and manufacturers of PV enhancers.
