The Analysis Performance of a Grid-Connected 8.2 kWp Photovoltaic System in the Patagonia Region
Round 1
Reviewer 1 Report
In this manuscript, Vidal et. al studied the performance installed in Magallanes region of Chilean Patagonia over one year. The measurement and simulated results were well presented in this manuscript. The study presented current operation and energy production from small photovoltaic systems grid systems connected operating in the southern regions of South America. I would recommend to publish this manuscript on Sustainability with some minor revision.
Minor issues:
- Table 3 and Table 4, please provide the description of each column names such as GlobHor, which is not included either under the table or in the main text.
- Page 12, Line 272 to Line 275, “which is higher than the one reported in Khatkar-Kalan (India), Warsaw (Poland) and Ballymena (Northern Ireland). This data is comparable to the data obtained inWarsaw (Poland), Dublin (Ireland) and As (Norway) but it was lower than the obtained information in Crete (Greece), Jaén (Spain), Nis (Serbia) and Eastern (India)”, please check the statement, the authors said the present study has final yield “similar to” and “higher than” Warsaw at the same time. Based on Table 5, the final yield of present study is similar to Warsaw (Poland) and “Khatkar-Kalan (India)” to me.

Reviewer 2 Report
More relevant references are needed for performance analysis of grid-connected PV systems. You must stress the differences of your work and consequently the novelty of your approach.
It is important to clear up your measurement set up because there is a comparison between measured and simulated values. Particularly in section 3.1, it would be significant to give more information about performance curves of inverter, to clear up how the measurements are recorded, which values are recorded. There is a datalogger?
Line 110: there are not power measurements?
Line 132: There is a pyranometers or reference cell in order to measure irradiation data?
Line 218-219: DC and AC energy generated are recorded by inverter inlet? There is a power meter in the experimental set up.?
Line 223-226: Which are the design parameters of simulation? There are parameters as dust accumulation or spectral effects, inverter efficiency. In this way may explain better the discrepancy.
How many years the system is in operation? There is possibility of degradation? In simulation model there is design parameter of PV degradation? Respectively, dust accumulation of region affects PV performance? There is a design parameter in simulation model for dust effects.

Round 2
Reviewer 2 Report
However the improvement of this paper is remarkable, I think that literature review can be improved in order to stress the novelty of your approach. Performance analysis of grid-connected PV systems is an important task which is faced with different ways. Furthermore, the novelty can be described clearly in the conclusions.
