A Predictive Reliability Model to Assess the Performance of Photovoltaic Systems

Round 1

Reviewer 1 Report

Dear editor,

Assessing and Predicting the Reliable Lifetime of the Photovoltaic Systems Based on their Performance are quite interesting, but the results need to be improved. There are some minor miss understanding that requires some modifications in the paper. After the following corrections paper may be acceptable for publication:

1. 
   The Abstract should be revised carefully.
2. The English and grammatical mistakes should be revised carefully and the monoculture needs improvement .
3. 
   the Introduction part needs to be developed and using some references [about 40–50% of the total generated electricity is consumed by the residential sector. Researchers have been putting more efforts to study and improving the performance of the photovoltaic systems as a solar energy harvesting technology ]

Suggested references:

DOI: 10.1126/science.1228604

https://doi.org/10.1007/s11837-020-04518-5

https://doi.org/10.1002/adma.202001243

https://doi.org/10.3390/engproc2021012081

Also, the originality of the work should be specified clearly in the introduction.

4. for The operational conditions paragraphs the formula should be numbered and the authors can explain how the parameters of field orientation can be adjusted for optimum performance.
5. the authors didn’t define and explain the choice of four factors (??, ??, ???, ??) for Taguchi OA design.
6. I recommend that the authors can add the range of the higher the temperature that gives the lower the PV system efficiency.
7. Figure 6. The reliability functions ?(?) of (a) field orientation (30° tilt, 0° azimuth), (b) field orientation (30° tilt, 20° azimuth) 491 and (c) field orientation (30° tilt, 30° azimuth), the figure is not visible, especially the labels.

Dear respected reviewer,

Thank you so much for your review and the valuable comments and suggestions you provided. This really improved the manuscript.

Please find the response to your comments and suggestions:

1. The Abstract should be revised carefully.    Done
2. The English and grammatical mistakes should be revised carefully and the monoculture needs improvement .  Revised and corrected
3.  the Introduction part needs to be developed and using some references [about 40–50% of the total generated electricity is consumed by the residential sector. Researchers have been putting more efforts to study and improving the performance of the photovoltaic systems as a solar energy harvesting technology ]     Three of the suggested references have been included

Also, the originality of the work should be specified clearly in the introduction.   Done in lines (135-144)

1. for The operational conditions paragraphs the formula should be numbered and the authors can explain how the parameters of field orientation can be adjusted for optimum performance.  The final formulae and formulae that may be needed in upcoming sections are labeled. Optimization of field orientation parameters is done through the investigating the simulation results and results of Taguchi OA experiments
2. the authors didn’t define and explain the choice of four factors (??, ??, ???, ??) for Taguchi OA design.   Done in line 254-261
3. I recommend that the authors can add the range of the higher the temperature that gives the lower the PV system efficiency. Done in lines 340-344
4. Figure 6. The reliability functions ?(?) of (a) field orientation (30° tilt, 0° azimuth), (b) field orientation (30° tilt, 20° azimuth) 491 and (c) field orientation (30° tilt, 30° azimuth), the figure is not visible, especially the labels. Redrawn with beiger fonts of Labels and values on axes

Reviewer 2 Report

Abstract: Move the first two lines from the abstract - This is introduction information
Then, "Renewable clean energy has been the interest of many researchers because of its positive 10 impact on the world" state what positive impacts are?
Line 318: This nonlinearity may be due to the dusty weather in months from May to August in Riyadh and month April in Cairo. What evidence author can prove for dusty weather (What does ot mean?)?
