Abstract
Solar photovoltaic technology is one of the most well established new and renewable energy technologies. Many researchers have undertaken wide research and development in this sector, including material and system design. To protect the exhaustion of global terrestrial land and to avoid the occupation of extensive farmlands, solar photovoltaic (PV) developers, as well as policymakers, have pursued various solutions, including the development of floating solar PV (FPV). This study consists of a technological and economic perspective to analyze the floating solar PV system. The authors utilize remote sensing results to predict FPV efficiency and measure energy yield from the system while also developing an economics analysis on an FPV project by comparison with ground-based solar PV (GPV). The results from the remote sensing method found that the lake has a cooler temperature than the ground, with an annual difference of around 8 °C. FPV efficiency was also shown to be around 0.61% higher than GPV in terms of the prediction. FPV economic parameter comparison also resulted in 3.37 cents/kWh lower levelized cost of electricity (LCOE), and 6.08% higher internal rate of return (IRR) compared to GPV in the base scenario.
Highlights
Consumption of energy is related to human welfare in life
The results showed that floating solar PV (FPV) efficiency is significantly superior to that of ground-based solar PV (GPV)
Economic analysis composes a variety of evaluation methods such as the levelized cost of energy (LCOE), net present value (NPV), internal rate of return (IRR) and power purchase agreement (PPA)
Summary
Consumption of energy is related to human welfare in life. Nowadays, the welfare of the world population is facing constraints of climate change that occur on earth after the period of industrialization. The electric power generation sector plays a significant role in total world energy consumption, where almost 70%. Listrik Negara (PT PLN), from Indonesia national energy general plan [2] estimates that a total potential capacity of 442.9 GW of electric power could be generated from renewable energy sources. A report from the national energy general plan explains that the average solar PV potential in Indonesia is. A new and renewable energy (NRE) technology and paradigm could constitute a solution to the problem of world dependence on fossil fuel-based energy. According to Indonesia’s state-owned electric company PT PLN’s statistical report [9], in 2018, the estimation cost of NRE in Indonesia was still very high (around 54.8 cents/kWh) compared to a traditional steam power plant (5.93 cents/kWh). The authors hope that the methodology and tools in this paper can be helpful to future FPV performance research
