Analysis on Operation Modes of Residential BESS with Balcony-PV for Apartment Houses in Korea
Round 1
Reviewer 1 Report
The main strength of the paper is its interesting and actual topic but there are lots more shortcomings:
- The title of the paper suggests that the authors provided some novel optimization procedures for residential photovoltaic and BESS systems but there is no optimization algorithm in the paper. Authors experimentally determined optimal operation schemes but for universal application, some kind of mathematical optimization is needed (objective function with constraints). In my opinion, the title of the paper does not reflect the actual contents of the paper.
- The scientific contribution of the paper is unclear. The literature review section is quite poor. Please, add more papers to literature reviews in order to clarify the scientific contribution of your manuscript.
- The sentence in rows 72 and 73 is unclear.

Title: Optimal Operation Schemes of Residential Battery Energy Storage Systems with Veranda Photovoltaic System for Apartment Houses in Korea
Overview and general recommendation:
The manuscript compares four operation scenarios of a PV in residential energy storage system. The manuscript is clear and well structured. Nonetheless, the manuscript does not present significant novelty or contribution to the field. For this reason, the reviewer is not convinced of the merit of the manuscript to be published.
Major comments:
1. The novelty and contribution to the scientific field should be clearly mentioned. The manuscript is a good description of an engineering problem, but the scientific merit is to be determined. Please clarify the readers.
2. The literature review is almost absent. The manuscript would benefit from an extended literature review where the work novelty and contribution can be grounded. In addition, self-citation should be reduced to the essential.
Minor comments:
3. The title is too long.
4. The abstract should present the main results and conclusions.
5. In the abstract is stated that residential BESS integrated with PV can reduce energy consumption and costs. Please clarify the reader how energy consumption is reduced by storing and managing the energy produced to match the energy needs leads to lower energy consumption.

Round 2
Reviewer 1 Report
The authors have changed the title and now it reflects the exact content of the paper. They also expand the literature review section and now it is much better.
