KawanSurya : PV Calculator for PC

KawanSurya is an innovative application aimed at helping individuals in Indonesia make informed decisions about rooftop PV systems. This application considers two crucial factors that can influence the decision to install a rooftop PV system: technical and economic aspects.

Firstly, KawanSurya provides detailed analysis of the technical aspects of rooftop PV systems. This includes assessing the potential for electricity generation from solar PV compared to overall electricity consumption. The application takes into account various factors such as location, roof orientation, shading, as well as the efficiency and output of the solar panels used. By analyzing these factors, KawanSurya can provide accurate estimates of the energy output potential and savings that can be achieved through the installation of a rooftop PV system. KawanSurya utilizes PVGIS irradiation data and also employs PV output equations from HOMER Energy to obtain accurate results.

Secondly, KawanSurya evaluates the economic feasibility of investing in a rooftop PV system. This includes analyzing the installation costs of the system, as well as the expected return on investment over time. The application considers various financial metrics such as payback period, net present value (NPV), and return on investment (ROI). Additionally, KawanSurya evaluates the regulations for exporting solar PV electricity to the national grid (PLN), ensuring that users are aware of any regulatory barriers or incentives (indonesia ministry of energy and mineral resources) that may affect the economic feasibility of their investment.

Overall, KawanSurya provides a comprehensive techno-economic analysis of rooftop PV systems in the on-grid system in Indonesia. By considering the technical and economic aspects of the investment, KawanSurya can assist users in making informed decisions about the installation of a rooftop PV system, ensuring that they are not only environmentally sustainable but also financially viable.
