Technical-economical assessment of solar PV systems on small-scale fishing vessels

Abstract

The source of lighting in ships can be sourced from electrical energy generated by using generators or now can utilize new renewable energy, such as solar energy using PV. Based on the existing potential, Indonesia has good solar energy potential. The measurement results show that the potential for solar energy reaches 6.37 kWh/m2/day. This potential can certainly be utilized in the marine and fisheries world. The utilization of PV as a source of electrical energy on fishing boats is expected to help support government policies in terms of the blue economy and overcome the limited number of fossil energy sources. In this study, the installation of PV with a size of 100 WP was installed on fishing boats. The need for electrical energy for PV energy output shows that it can meet 50.52% of electrical energy needs. This result is supported by the Wilcoxon test that electrical energy needs can be met by PV with a p < 0.005. The results of the economic analysis also show that the use of solar energy as a source of electrical energy provides an IRR of 9%, with a payback period of 8.87 years.

Analysis of oscillating water column technology in East Nusa Tenggara Indonesia

“…This procurement uses very high financing and the lack of feedback from the consumption of electrical energy provided by state electricity company is still not balanced. The fulfillment of this energy comes mostly from the burning of fossil fuels that are millions of years old and cannot be renewed and only a small part comes from the use of other, more renewable sources [8]− [13]. Seeing the topography of East Nusa Tenggara which is surrounded by the sea, this type of ocean wave power plant is suitable to be built [10], [12], [14].…”

Seeing the topography of East Nusa Tenggara which is surrounded by the sea, this type of ocean wave power plant is suitable to be built [10], [12], [14]. Apart from being environmentally friendly, this type of power plant will not damage the natural ecosystem during construction and operation, so it will become a famous tourist destination for its natural beauty [15]− [22].…”

Technical, economic, and social impact of photovoltaic at dormitory building

“…The need for electrical energy every year is always increasing. These needs come from households, government, business, and also the world of education [1]- [3]. In the world of education, electrical energy is useful for supporting all facilities and infrastructure in the learning process, both in the classroom, laboratory, and workshop [4].…”

Application of PV systems in the process of drying fish for traditional fisherman

“…Fish drying machine is made using solar energy which is then used to help the fish drying process [22]. The potential of solar energy that is so good in Indonesia is one of the reasons for using this energy [23], [24]. The tool made will also be able to be integrated with IoT so that it can make it easier to know the condition of drying fish [25]− [27].…”
