Wind Power and Solar PV renewable energy generation on an Island of Great Cumbrae

The aim of the project is to design a renewable energy system that can meet the current and projected electricity demands for the island of Great Cumbrae. This should be achieved by providing a stable electricity output and the meet the calculated total annual base load supply of 11.29 GWh. In addition to providing a stable supply of electricity, the environment and social impacts that arise from the project relating to Great Cumbrae should be minimised as well as coi...

RADIOISOTOPE THERMOELECTRIC POWER GENERATION

Sustainable energy sources have been a topic of interest over a period of time for many researchers. Nuclear energy is one of the sources that have long been exploited for generating heat and electricity both in large scale and small scale. One of the methods for converting this heat into electrical power is using thermoelectric generators. Radioisotope thermoelectric generators are currently the longest-lived sources of energy; it does not require any human maintenance or refuelling. This pa...

Design and Construction of a 20-m Distance Remotely Controlled Metal Detector Using Arduino

   AbstractThe project DESIGN AND CONSTRUCTION OF A 20-METRE DISTANCE REMOTELY CONTROLLED METAL DETECTOR is used for detecting metallic objects such as phones, bombs, and other metallic objects that are hidden from view. The design is based on the principle of the Resonant Frequency Oscillator (RFO) metal detectors in which oscillation is a function of parallel connection of an inductor and a capacitor operating in resonance. The project is divided into two ...

Carrier Transport and Recombination In A-SI: H PIN Solar Cells in Dark and Under Illumination

Abstract A study has been carried out on the forward bias dark current and the short circuit current-open circuit voltage characteristics of a-Si: H pin solar cells over wide range of illumination intensities. Results are presented with superposition of these characteristics over extended current voltage regimes. This and the observed separation between these characteristics are consistent with the arguments presented based on first principle arguments.

Optimization of open circuit voltage in amorphous silicon solar cells with mixed-phase (amorphous+nanocrystalline) p-type contacts of low nanocrystalline content

Both the origins of the high open circuit voltages (VOC) in amorphous silicon solar cells having p layers prepared with very high hydrogen dilution and the physical structure of these optimum p layers remain poorly understood topics, with several studies offering conflicting views. This work attempts to overcome the limitations of previous studies by combining insights available from electronic measurements, real time spectroscopic ellipsometry, atomic force microscopy, and both high-resoluti...

Industrial Symbiosis for Very Large Scale Photovoltaic Manufacturing

In order to stabilize the global climate the world’s governments must make significant commitments to drastically reduce global greenhouse gas (GHG) emissions. One of the most promising methods of curbing GHG emissions is a world transition from fossil fuels to renewable sources of energy. Solar photovoltaic (PV) cells offer a technically sustainable solution to the projected enormous future energy demands. This article explores utilizing industrial symbiosis to obtain economies of scale an...

Optimizing Design of Household Scale Hybrid Solar Photovoltaic + Combined Heat and Power Systems for Ontario

This paper investigates the feasibility of implementing a hybrid solar photovoltaic (PV) + combined heat and power (CHP) and battery bank system for a residential application to generate reliable base load power to the grid in Ontario. Deploying PV on a large-scale has a penetration level threshold due to the inherent power supply intermittency associated with the solar resource. By creating a hybrid PV+CHP system there is potential of increasing the PV penetration level. One year of one seco...

Cleaner production via industrial symbiosis in glass and largescale solar photovoltaic manufacturing

In order to alleviate production costs and increase the environmental performance of solar photovoltaic manufacturing, an eco-industrial park for GW-scale production of PV is proposed. This article quantifies the inputs and outputs for the glass manufacturing component of such a system using standard manufacturing techniques. Utilizing industrial symbiosis in this way, potential reductions for such a plant were found to be about 30,000 tons/year in raw materials and over 220,000 GJ/year in em...

Leveraging Photovoltaic Technology for Sustainable Development in Ontario's Aboriginal Communities

"The Ontario feed-in tariff (FIT) for solar photovoltaic (PV) technology has provided Ontario's Aboriginal communities with an opportunity to i) weaken the cycle of poverty; ii) directly counteract climate change by producing renewable energy; and iii) become more self-sufficient. This paper critically analyzes the technical, cultural, and economic viability of leveraging the FIT for PV to provide green electricity and revenue to assist First Nations communities in sustainable development. A ...

Dispatch Strategy and Model for Hybrid Photovoltaic and Trigeneration Power Systems

The advent of small scale combined heat and power (CHP) systems has provided the opportunity for in-house power backup of residential-scale photovoltaic (PV) arrays. These hybrid systems enjoy a symbiotic relationship between components, but have large thermal energy wastes when operated to provide 100% of the electric load. In a novel hybrid system is proposed here of PV-trigeneration. In order to reduce waste from excess heat, an absorption chiller has been proposed to utilize the CHP-produ...

A Review of Solar Photovoltaic Levelized Cost of Electricity

As the solar photovoltaic (PV) matures, the economic feasibility of PV projects are increasingly being evaluated using the levelized cost of electricity (LCOE) generation in order to be compared to other electricity generation technologies. Unfortunately, there is lack of clarity of reporting assumptions, justifications and degree of completeness in LCOE calculations, which produces widely varying and contradictory results. This paper reviews the methodology of properly calculating the LCOE f...

Diverting Indirect Subsidies from the Nuclear Industry to the Photovoltaic Industry: Energy and Economic Returns

Nuclear power and solar photovoltaic energy conversion often compete for policy support that governs economic viability. This paper compares current subsidization of the nuclear industry with providing equivalent support to manufacturing photovoltaic modules. Current U.S. indirect nuclear insurance subsidies are reviewed and the power, energy and financial outcomes of this indirect subsidy are compared to equivalent amounts for indirect subsidies (loan guarantees) for photovoltaic manufacturi...

Institutional-Scale Operational Symbiosis of Photovoltaic and Cogeneration Energy Systems

Due to the negative environmental effects of fossil fuel combustion, there is a growing interest in both improved efficiency in energy management and a large-scale transition to renewable energy systems. Using both of these strategies, a large institutional-scale hybrid energy system is proposed here, which incorporates both solar photovoltaic energy conversion to supply renewable energy and cogeneration to improve efficiency. In this case, the photovoltaic reduces the run time for the cogene...
