Reviewer 1 Report
In the submitted manuscript, the development of low-cost solar power system technologies in Africa is presented. The manuscript is in general well organized and it would be of interest to the research community in this field of work as it offers results that are of not only theoretical value, but also useful in practice. For instance, the review and the drawn conclusions would support developers and engineers in their work.
In order to improve the readability and clarity of the manuscript, a few minor remarks need to be addressed before the paper is to be accepted for publishing:
1) English needs to be improved throughout the paper. In certain places a better choice of words could be made and also certain places in the text demand better ordering of words. For example the abbreviations (as Goal 7, CSP…etc.) in the abstract section should be avoided!
2) The font size on more figures (especially the text on Figures 1) should be increased for better readability!
3) The introduction section should be extended more. There are many other research results in this field that should be mentioned by the authors as research backgrounds in the “Introduction” section of the paper. By this way the “Introduction” and also the “References” sections of this paper should be completed with the under mention relevant references especially that relates to this field:

Please put these references into the text of the following added sentence (in line 30):
“Electrical energy is one of the most crucial resources that drives the growth and development of any given nation [1-2].”

Please put these references into the text of the following added sentence (in line 34):
“It is therefore very urgent for countries all over the world to adopt sustainable sources of producing electrical energy to meet their energy needs [4-5].”
Please complete the References section of your paper with these referred papers: with numbers [1]; [2]; [4]; [5] references!
4) The reference style of the “References“ section of the recent paper does not meet with the requirements of the journal. Please check the relating formal requirements in the “guide for authors” again and correct it following the instructions!
To improve the paper based on these minor modifications are very significant to have success in acceptance for publication!
Thank you for your consideration in advance!
