“…These values were calculated using a previous reference, which is a report issued in 2011 by the Intergovernmental Panel on Climate Change (IPCC) [32]. In the previous research, the annual O&M costs of PV panels were assumed to be approaching 0 [33]. We also assumed the lifetime of a PV array as 25 years.…”

“…Batteries are the most difficult component to model. Thus, we use sensitivity analysis to select both the Surrette 6CS25P battery (6.94 kWh) (Rolls/Surrette, Springhill, NS, Canada) and the Hoppecke 20 OpzS2500 battery (5 KWh) (Hoppecke, New Jersey, NY, USA), which are widely used for hybrid energy system analysis in this study, as a storage system to analyze and simulate the optimal hybrid energy system [33,[35][36][37].…”

“…The HOMER simulation applied used the kinetic battery model. This model is named as a "two-tank system", which means one battery pack can be recharged for consumption at any time, whereas the other battery pack can be discharged with a constant electric current [33]. For the sensitivity analysis of the battery in Jindo-gun, cases with a total of 0, 55, 60, 65, 85, 90, and 95 batteries are implemented.…”

Comparative Analysis of On- and Off-Grid Electrification: The Case of Two South Korean Islands

et al. 2016

South Korea's main industry is the manufacturing industry, and it requires stable energy. Korea heavily relies on importing oils to produce energy, thus efficient energy management is critical. This is why many renewable and smart energy policies and infrastructure planning are being set up currently. Supplying reliable and sustainable renewable energy to remote areas has especially been questioned; therefore, adopting sustainable and clean energy based on renewable resources cannot be delayed any more. This research examines the most economically, technologically and environmentally suitable energy grid of two South Korean Islands. Several hybrid energy system configurations that analyze and identify the optimal grid-connected and grid-independent hybrid power generation systems are simulated in this study. According to the results of the study, the optimal regionally detached power generation system was the wind-PV-battery-converter hybrid system. At the end of this paper, implications and limitations are discussed.

“…Long term assessments for grid connect PV systems for residential power generation were conducted for eleven main cities in Queensland-Australia using a computer simulation [6]. The impact of PV panel slope on energy fed to grid, investment cost, financial income, and CO 2 emission were also studied.…”

This paper assesses 4 years of operation of a 1.75 kW roof top solar PV system installed in a Sydney suburban house. The system consists of 10 PV panels, a DC/AC inverter, and a grid connected gross meter. Solar electricity delivered to grid is verified with the results from a computer simulation package (PVSYST) by adopting the installed component specifications, operation conditions, and weather data of the site. The results show high consistency between the values of energy delivered to the grid measured by the energy company and the energy estimated by system simulation. New system performance indicator is developed and called the optimum performance compliance ratio (P CR ). It is a measure of the compliance of the output of the designed PV system with the output which would be produced by the same system with a solar tracker. This indicator provides system designers, contractors and energy providers with the actual capacity of the system that they can offer the end-users.

“…Nevertheless, Liu [8,9] has performed a system optimization for using PV and battery to power residential buildings in Queensland, and finds that, 6 kW roof-mounted panels with an angle of 20-25 degrees can provide nearly two-thirds of the electricity requirements.…”

Traditional light bulbs (e.g., incandescent, fluorescent) use too much electricity, convert very little energy into light of sufficient quality and in their production use toxic contaminants. During the last few years, a new type of light source, LED (light emitting diode) bulb, has gained increasing popularity and its costs are set to plunge even further. LED bulbs offer many advantages over traditional sources, and they can be used as a direct replacement to existing lighting. This paper will use a spreadsheet-based analysis with hourly solar data supplied by Ecotect to show that, the efficiency of LED installations can be increased when used in conjunction with photovoltaic modules, as the two generate (and use) DC (direct-current) electricity, thereby eliminating intermediate-level losses in the electronic circuitry. If a storage battery is included, the solar panels generate electricity during the times when the occupants are not necessarily using the lighting, but the stored electricity can be used to power the lighting when the energy is required. The latest results demonstrate that, a slight reduction in the required floor area to be lit allows the solar-battery-LED system to be implemented in small buildings using a storage battery size that is within the range of present commercial devices.
