Dear Ms. Mentari Putri Jati,
Thank you for your request,
It is unfortunate that this system does not allow inserting the figure. Therefore, I
would like to describe the system topology. Hopefully you can find the description
satisfactory.
The system consists of 8 panels x 545 Wp. These panels generate DC voltage and
this voltage is connected to a 15 kW on-grid inverter. This inverter generates
voltage synchronised with the electricity from the grid. This constructs the grid-
connected system for load sharing in the building. On a sunny day, the electricity
from the panels may be surplus and supplied back to the grid. But at the night or
cloudy condition, the electricity from the panels is small or even zero. In this
condition the load takes the power from the grid. Therefore, in one month an
electricity customer may need to pay/get paid for the electricity.
Thank you for sharing your research results. I want to ask a few things about your
research. First, on the design you do, what software you use. Second, where did you
get the solar intensity capacity data used in this design? Is the solar intensity
capacity data used the solar intensity capacity data in a year or more? Thank you

Dear Dr. FA. Rudi Sambada,
Thank you for your questions.
1. The software that we are using is PVSyst. This is one of the software, normally
used for solar PV design. As far as we know there are 7 seven software packages
available for solar PV design. Every software has its own advantages and
disadvantages. The choice of using this software is as it is user-friendly and the
feature is sufficiently complete.
2. The software also provides the facility to give the data on solar capacity in the
area where the system will be established. However, in this study, the data is also
confirmed by real measurements, like the intensity of light, the radiance, the
temperature etc.
3. Since the estimation is determined for a year than a measurement the whole
year may be difficult. Hence, the generated solar resources are taken for the
information generated by the software. In this study the data coverage is one year.
