Like all modes of transportation that use fossil fuels, ships produce carbon dioxide emissions that significantly contribute to global climate change and ocean acidification. Additionally, ships release other pollutants that also contribute to the problem and exacerbate climate change. Considering the large volume of ships on the high seas, ship emissions pose a significant threat to human health. The ocean is exposed to vast amounts of sunrays and has a great potential to be explored by the maritime sector and green power industry. Solar energy hybrid assisted power to support auxiliary power for the instruments on board the vessel is explored in a UMT vessel. The vessel that is used in this case study is Discovery XI, which is a 16.50 meter diving boat owned by University Malaysia Terengganu. The study explores the feasibility of using solar energy as a supporting power for marine vessel auxiliaries. The reduction of fuel usage after installing the solar PV system on the boat is determined, as well as an economic analysis. The power requirement for the vessel’s electrical system is estimated. The fuel and money saved is also estimated for comparison purposes of the vessel using the solar PV system and the vessel without the PV system. Economic analyses are performed, the Annual Average Cost (AAC) between a vessel using solar PV system and a vessel without solar PV system is estimated, and the period of the return of investment for the vessel with solar PV system is also estimated. The use of a photovoltaic solar system to assist the boat power requirement will benefit the environment through Green House Gas (GHG) reduction, and the use of solar as a supporting alternative energy could cut the cost of boat operation through fuel savings.

Net Energy Metering

Malaysia has moved forward by promoting the use of renewable energy such as solar PV to the public to reduce dependency on fossil fuel-based energy resources. Due to the concern on high electricity bill, Universiti Malaysia Perlis (UniMAP) is keen to install solar PV system as an initiative for energy saving program to its buildings. The objective of this paper is to technically and economically evaluate the different sizing of solar PV system for university buildings under the Net Energy Metering (NEM) scheme. The study involves gathering of solar energy resource information, daily load profile of the buildings, sizing PV array together with grid-connected inverters and the simulation of the designed system using PVsyst software. Based on the results obtained, the amount of solar energy generated and used by the load per year is between 5.10% and 20.20% from the total annual load demand. Almost all solar energy generated from the system will be self-consumed by the loads. In terms of profit gained, the university could reduce its electricity bill approximately between a quarter to one million ringgit per annum depending on the sizing capacity. Beneficially, the university could contribute to the environmental conservation by avoiding up to 2,000 tons of CO2 emission per year.

<p>At present, solar energy is perceived to be one of the world’s contributive energy sources. Holding characteristics such as inexhaustible and non-polluting, making it as the most prominent among renewable energy (RE) sources. The application of the solar energy has been well-developed and used for electricity generation through Photovoltaic (PV) as the harvesting medium. PV cells convert heat from the sun directly into the electricity to power up the electric loads. Solar PV system is commonly built in a rural area where it cannot be powered up by the utility grid due to location constrains. In order to avoid the electricity fluctuation because of unsteady amount of solar radiation, PV solar hybrid is the efficient solution for rural electrifications. This paper presents a review on optimised Hybrid Solar-PV Diesel system configurations installed and used to power up off grid settlements at various locations worldwide.</p>

Due to global climate change as a result of pollution caused by the burning of fossil fuels, the world has changed its view when it comes to power generation. The focus is now more on natural and clean energy, such as solar PV systems. An effective solar PV system is not a simple system, as the sun is not a stationery object. The sun moves from east to west daily and that makes the design and installation of an effective solar PV system challenging for optimal power harvesting. The purpose of this paper is to compare two algorithms (linear regression and fuzzy logic) that are applied to a dual-axis tracker in order to maximize the output power yield that may be obtained from a fixed-axis system. One fixed-axis PV module serves as the baseline for comparing the results of the dual-axis trackers that are controlled by the two algorithms. A key recommendation is to align a PV module perpendicular to the sun from sunrise to sunset using a control algorithm based on fuzzy logic principles in order to extract the maximum amount of available energy.

The limited fossil fuels and demand for the energy made renewable a booming source of generating energy. An enormous amount of solar energy made it a best alternative renewable energy, which is free of cost and unlimited source of energy, eco-friendly and sustainable to the environment. But during the execution of panels on land has the burden of intense land requirements which is a premium commodity. The hurdles faced are land availability, land acquisition, land development and, land evacuation. Earth is covered with 70% of water. So, most of the solar energy is captured by water compared to land. To conserve the valuable land and water, installing a solar PV system on water bodies like oceans, lakes, lagoons, reservoirs, canals and water storage tanks are an appropriate option. They have numerous advantages compared to land installed solar panels. They reduce the valuable land area, reduce evaporation of drinking water, cooling of solar panels by the water below the panels. Additionally, the aquatic environmental profits by the solar installation limit the algae growth and potentially improves water quality. In this paper a new method of the float was discussed, a comparison is made between the floating PV system and standalone PV system. This method also improves the efficiency of the solar panel. A Small prototype has been designed and the results were plotted for different loads.

The Impact

Climate is rapidly changing with disruptive impacts. Without decisive action, energy-related greenhouse gas (GHG) emissions would lead to climate degradation. All types of energy efficiency technologies will require widespread deployment, as global warming is likely to reach 1.5°C between 2030 and 2052, if it continues to increase at the current rate. Photovoltaic (PV) energy is one of the most promising emerging technologies in mitigating the impact of climate change. PV is the name of a method of converting solar energy into direct current electricity. Therefore, the objectives of this article are to study the initiatives taken by energy development agencies in India for promoting renewable sources of energy, to study the use of solar power as a renewable source of energy through PV system and to analyse the solar PV rooftop system in Chandigarh as a case study. The article is an empirical study based on primary data. For the purpose of collecting the primary data, a structured questionnaire was prepared for citizens and an interview schedule for officials. The results of the study show that the majority of the citizens were satisfied with the solar photovoltaic (SPV) installations in Chandigarh, while a very few of them were dissatisfied and their dissatisfaction revolved around getting clearances from different departments.

Solar energy, wind energy, and a combination of wind and solar energy have been used successfully to power an UV (ultraviolet) water purification system. Five different solar and wind energy systems have been tested and although these renewable energy systems have been used for water purification, graphs contained in the paper can be used to determine the feasibility of powering other electrical loads. Combining a 100-W solar-PV system with a 500-W wind turbine resulted in pumping and purifying enough water to satisfy the potable water requirements of 4000 people (16000 liters/day) at an estimated equipment cost of $4630.

<span lang="EN-US">In this work, the fickleness of solar energy can be overcome by using Maximum Power Point Tracking algorithm (MPPT). Perturb and Observation (P&amp;O) MPPT algorithm accomplish fast the maximum power point for rapid change of environmental conditions such as irradiance intensity and temperature. The MPPT algorithm applied to solar PV system keep the boost converter output constant. Output from boost converter is taken to three phase impedance-source inverter with RL load and grid system. Impedance-source inverter performs the transformation of variable DC output of the solar PV system in to near sinusoidal AC output. This near sinusoidal AC output consecutively is served to the RL load first and then to grid system.
