AbstractSolar energy is gaining more attention than ever before due to its potential ability to provide the world energy needed at a sufficient and reliable rate. Putting more focus on its optimum harvesting and utilization can eventually solve the problem of energy shortage by balancing up the energy demand of the nation. Adequate information on the output voltage of the solar panel to cope with the output current during the daytime is essential to be able to predict accurately the estim...

PERFORMANCE EVALUATION OF MONO-CRYSTALLINE PHOTOVOLTAIC PANELS IN FUNAAB, ALABATA, OGUN STATE, NIGERIA WEATHER CONDITION

AbstractThe current-voltage characteristic is the basic descriptor of photovoltaic device and is used to test the performance of PV panel. The manufacture specifications on solar panels are obtained under standard condition (solar irradiance of 1000 W/m2, AM 1.5 and operating temperature of 25oC) which is not the real operating condition the solar panels are exposed to on the installation site. With this, the information obtained from the manufacture specifications would not be sufficient ...

Analysis Of Radio Propagation Characteristics For An Operative GSM Network

Abstract: This research work seeks to analyze the radio propagation characteristics of a GSM operative network using Makurdi as a case study. The analysis of radio propagation by a GSM operative entails the characteristics/ behavior of the radio wave between the transmitter and the receiver. An understanding of the radio wave propagation characteristics of an environment is a necessary condition for effective radio network planning which translate to the determination of the coverage stre...

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...

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.

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.
