Multivariant Analysis of Photovoltaic Performance with Consideration of Self-Consumption

Round 1

Reviewer 1 Report

This is a technical paper conducting a modelling-based study aiming to further develop and understand the economic profitability of PV system in different scenario subject to polish context. The work is interesting, but some comments should be addressed before the consideration for publication.

·        The paper is generally well written, but the novelty and originality of the paper should be further clarified compared to the presented state of the art in the introduction section.

·        Weekly or daily profile of the buildings’ energy consumption should be provided.

·        “Due  to the simplicity of connecting a PV system to the electrical grid, nominal power of the PV power plant cannot be higher than 50 kWp” Please express this sentence with a more enhanced point of view.

·        The authors need to mathematically define in a rigorous fashion the KPI and the parameters under analysis in Section 2.3.

·        For the sake of clarity, fig.5 layout needs to be improved using different colours for the different cases. In addition, graphic supports are highly recommended for a better understanding of the results.

·        The authors should provide the economic figures either in Euros or in US dollar in order to reach a wider audience.

·        The authors mentioned the introduction of a new regulation (net billing) for the energy market regarding PV installation. It would be of great interest to economically compare the results achieved using both the “net metering” and the “net billing” approach.

·        The Conclusion section should be strengthened in order to highlight better the benefits provided to the proposed approach.

Reviewer 2 Report

The manuscript contains a comparison of a different photovoltaic system approach in terms of monthly energy production profiles with detailed user needs profiles.

To demonstrate its applicability simulations using the proposed strategy are performed.

Comments:

-          Manuscript is well organized and English language is fine.

-          The manuscript meets the requirements of a literature study regarding the polish legislation, the methodology and presentation are also sufficiently addressed.

Despite these features, the paper has not adequate credit published related works and do not show how the study differs from other literature studies.

The manuscript content does not present the necessary scientific complexity to be published in a journal. The performed analysis, despite being well developed and structured, is very simple and technical, and mostly based on the results returned by the PVsyst simulation platform.

I think the content is best suited to be published in a conference.

Reviewer 2 Report

Congratulations to author. He improve the article by responding to all the reviewer’s suggestions.
So, the quality of the paper increased substantially, and by this reason in my opinion the manuscript is now ready for publication.
