This paper proposes the optimization of Photovoltaic-Battery system with MPPT-based charge controller using Evolutionary Programming in MATLAB. Therefore, this research includes the determination of appropriate system voltage, battery bank, Photovoltaic array and inverter needed in order to fulfill the required load. On the other hand, the selected photovoltaic module will be identified from different...
Solar electricity from Grid-Connected Photovoltaic (GCPV) systems has experienced rapid growth as one the most important renewable energy technologies globally. However, due to the intermittent and fluctuating weather conditions throughout the day and year, it is often a challenge to model the output performance of a GCPV system. This paper presents a model for modeling the AC power from a GCPV system...
This paper presents a Bat Algorithm (BA) for sizing optimization of Grid-Connected Photovoltaic (GCPV) system. BA was used to search for the optimal photovoltaic (PV) module and inverter from their respective databases such that the expected Specific Yield (SY) in kWh per kWp could be maximized. In addition, the sizing process also involves the dimensioning of PV array and matching of PV array to...
Temperature of the photovoltaic (PV) module of a PV system is a significant factor in PV system operation. As the module temperature increases, the voltage of the module decreases. This leads to a reduction in the overall output power. As a result, the modeling of operating PV module temperature is important to investigate the climatic factors which affect the PV module temperature. This paper presents...

The study was conducted...
The D-region is the lowest layer of the ionosphere. During nighttime, the lack of ionization source from the Sun makes this region difficult to measure. This region has no measurable effects on Ionosonde frequencies. Rocket measurements are accurate but limited to the location, time and high in cost. Very Low Frequency (VLF) signal from the communication and navigation instruments can effectively...
