“…The figure shows the system's daily useful energy referred to the nominal power and the losses that occurred. Those losses include the collection losses that happened because of thermal, wiring, shading, or other inefficiencies [23], [24]. Also, the system loss which in the case of the proposed method happened because of inverter inefficiencies [25]- [27].…”

A solar cell is a type of renewable energy engineering technology that can convert photons coming from the sun to be converted into electrical energy. The amount of energy that can be converted by a solar cell is determined by the effective insolation time. Peak sun hours (PSH) are the focus of this research. This PSH analysis aims to determine the potential for solar energy obtained in geographical locations throughout the year. Geographical location and the position of the astronomical coordinates of a certain area affect PSH. Therefore, the orientation of solar panel installation, including the height, slope, and latitude of the solar panel surface needs to be considered in order to get maximum solar energy. The results of this study can be used by technicians in determining the orientation of solar panel development in an area.

“…The blend of these two state-of-the-art technologies, DC microgrids and fuel cells, has already been proven to be practical and promising [3][4][5]. In [4], a comparison between three DC bus voltage levels was conducted to assess which factors impact the overall efficiency of the microgrid. It was concluded that the efficiency of the DC microgrid is strongly dependent on the voltage level, efficiency of the power converter and parasitic ohmic losses [4].…”

The use of fuel cells in DC microgrids has been receiving a lot of attention from researchers and industry since both technologies can deliver clean energy with little to no environmental impact. To effectively integrate fuel cells in DC microgrids, a power converter that can equate the fuel cell’s voltage with the DC microgrid’s reference voltage is required. Based on the typical output voltages of fuel cells, buck-boost topologies are commonly used in this type of application. A variety of DC-DC buck-boost topologies, showing distinctive merits and drawbacks, are available in the literature. Therefore, this paper compiles, compares and describes different DC-DC buck-boost topologies that have been introduced in the literature over the past few years. Additionally, some design considerations are addressed, and future work is proposed.
