Feasibility and Techno-Economic Evaluation of Hybrid Photovoltaic System: A Rural Healthcare Center in Bangladesh

Abstract

This study aimed to investigate a techno-economic evaluation of the photovoltaic system, along with a diesel generator as a backup supply, to ensure a continuous twenty-four hours power supply per day, no matter the status of the weather. Healthcare centers in Bangladesh play a vital role in the health issues of the residents of rural areas. In this regard, a healthcare center in Baliadangi—Lahiri Hat Rd, Baliadangi, Thakurgaon, Bangladesh, was selected to be electrically empowered. The simulation software Hybrid Optimisation Model for Electric Renewables (HOMER) and the HOMER Powering Health tool were used to analyze and optimize the renewable energy required by the healthcare center. It was found that the healthcare center required a 24.3 kW solar PV system with a net current cost of $28,705.2; the levelized cost of electricity (LCOE) was $0.02728 per kW-hours, where renewable energy would provide 98% of the system’s total power requirements. The generator would provide 1% and the grid would supply the remaining 1%. The load analysis revealed that the hybrid PV system might be superior to other power sources for providing electricity for both the normal function and the emergencies that arise in healthcare’s day-to-day life. The outcome of the study is expected to be beneficial for both government and other stakeholders in decision-making.

Energy Efficiency in Heat Pumps and Solar Collectors: Case of Slovakia

“…According to Ma and Javed, it is optimal to make hybrid system of RES [49]. Analysed RES types can be considered for RES microsystems and hybrid photovoltaic systems, which could be better in comparison to other energy sources [50,51]. To make an effective energy system, the combination of solar water heaters and smart buildings can be considered as well, as determined by Zening et al [52].…”

“…The COE is the mean cost of fruitful electrical energy per kWh, and is one of the most important parameters for comparing the cost effectiveness of hybrid systems and for finding the optimal size of the system [8][9][10]13,15,17,20,50].…”

Design and techno-economic evaluation of hybrid renewable energy system for an Upazilla Health Complex (UHC) in Bangladesh

“…Auto-sized generators uses diesel for designing a model. The diesel price is estimated at $0.872/liter [28] . As shown in Table 6, the component capital cost is $160 and replacement cost is $128 and the maintenance and operation cost is $0.01 per hour.…”

“…The term payback period refers to the amount of time it takes to recover the cost of an investment. So, in this system total power generation is 53,736 kWh per year and the electricity cost is $0.97 per unit [28] .…”
