Round 1

Reviewer 1 Report

The work is very good and easy to follow.

However, the suggested solution is restrictive, only to a 36-cell-module what happens to 60-cell or 72-cell module? Could you comment on this? It should be addressed in this paper since the improvement is so significant. 

What is the cost of the SPDT compared to bypass diode? How about the simplicity of connecting the switches compared to bypass diode? Comments on this would add to the authenticity of  your solution.

Reviewer 2 Report

In this article, the authors are addressing the problem of a decrease in efficiency due to the shading of the mono-crystalline PV modules. The authors have simulated 5 different scenarios with and without shading and have proposed a switching based scheme to minimize the effect of the shading. I can recommend the article for publication only if the following concerns have been clarified.  

  1. The effect of shading is different for different type of PV modules. For example, thin-film PV modules have a less severe effect than those of mono-crystalline modules used for this research [1]. So, it would be useful for the reader if it is specifically mentioned in the article that these simulated effects are for mono-crystalline PVs only and may differ for other types of PV modules. It should be mentioned why mono-crystalline PVs were selected for this research. 
  2. The used model is not being discussed in this article. The only thing reader knows after going through the article is that MATLAB Simulink was used for modelling and simulation. The reader needs to know the details of the model.
  3. Page 5, line 116 and 117: Figure used twice (e.g. Figure Figure 5). Correction required.
  4. Table 2: Left most column: It is confusing for the reader as the 5 different cases presented above are also mentioned as modes. The reader can easily get confused because there are only 3 modes in which the circuit is simulated. So, please update the table (use case 1 . . . case 5 instead of modes).
