Round 1

Reviewer 1 Report

This manuscript can be accepted for publication after major revisions, see the followings:
*English should be improved.
*The Abstract should be improved.
*Better description and explanation on the figures (Figures 2 to 3).

*Better description and explanation on the tables (Figures 2 to 4).
*The validation part should be added.

* The novelty is not clear.
*The Conclusion could, also, be improved.
* Introduction part needs to be extended by some of the recently published papers to show the importance of Solar Energy Systems in high-quality journals. The following references should be included in this manuscript:

Reviewer 2 Report

The manuscript is interesting and provide useful data; however, it needs following revisions to become acceptable for publication:

1. Adding some important quantitative data and results in abstract is suggested.

2. Writing needs recheck and improvement.

3. Since the study is on solar radiation, it is better to consider "radiation" in the title of the manuscript.

4. Unit of data must e added on both vertical and horizontal axes of the figures, i.g. figure 2.

5. In conclusion section, it is better to avoid representing several quantitative results, it is better to just indicate the most important ones.

6. Adding nomenclature and definition of abbreviations is suggested.

7. Following references are suggested to improve literature review on the applications of intelligent methods and solar energy systems:
