Solar Energy

Solar energy is a renewable and abundant resource that holds immense potential for meeting the world's growing energy demand while mitigating climate change. Accurate assessment of solar radiation patterns and availability is crucial for the efficient deployment of solar energy technologies and the optimization of renewable energy systems.This research project aims to conduct a comprehensive solar panel/ solar inverter resource assessment in the University Of Benin Ugbowo, Nigeria, to evaluate the solar energy potential around it. The study employs an approach which involved integrating satellite data analysis, gotten from the National Aeronautics and Space Administration (NASA) to quantify solar irradiance levels and characterize solar radiation . The findings of this research project will provide valuable insights into the periods of best insolation and also environmental factors influencing solar resource availability in the University Of Benin.Most domestic appliances such as personal computers, television sets and lighting systems among others, operation has largely been controlled by hydro-electric power supply [National Grid]. This is not much a reliable source of energy due to the persistent power failure from our only reliable Nation Grid in the country, which has been the result of low water level in the dam(s) during harmattan season, faulty underground cables and transformer failures. Nigeria's energy sector is characterized by a dominance of fossil fuels, which contributes to climate change, air pollution, and environmental degradation. The country's renewable energy resources, particularly solar energy, remain largely untapped. This project seeks to contribute to the development of Nigeria's solar energy sector by designing, installing, and testing a solar powered energy system with an inverter.

This study focuses on the design, fabrication, and performance evaluation of a solar thermal dryer developed using locally available materials to enhance the drying of agricultural products in both rural and urban environments. Traditional open-air drying methods commonly practiced in Nigeria are fraught with challenges such as contamination, theft, unfavorable weather, and inconsistent drying rates, leading to significant post-harvest losses. To mitigate these limitations, a solarpowered thermal drying system was developed to harness the abundant solar energy available in tropical regions. The research methodology involved a comprehensive review of literature on solar energy utilization, the development of suitable design concepts, determination of relevant design and environmental parameters, material selection, fabrication, and experimental testing. The solar dryer design integrates a photovoltaic-powered air blower and a thermally heated chamber, providing controlled airflow and consistent heat distribution for effective moisture removal. Findings from related studies and prototype evaluations revealed that solar thermal dryers offer improved drying efficiency, reduced drying time, and enhanced product quality compared to conventional methods. The project demonstrates the potential for affordable, energy-efficient, and environmentally sustainable drying technology adaptable for small-scale farmers and households. Furthermore, the design can be scaled up for commercial use, promoting local manufacturing, job creation, and the wider adoption of renewable energy technologies in Nigeria.

This study investigates the possibility of using solar energy as an alternative to the University of Benin's unstable electrical supply from the Benin Distribution Company (BEDC). Using a descriptive survey approach, data was collected from 100 students using a standardized questionnaire and analyzed using mean and standard deviation. The findings show that an irregular power supply disturbs academic activity, but solar energy provides economic and environmental benefits. However, obstacles such as funding and policy constraints exist. The analysis suggests supportive policies, financial incentives, and investments to encourage using solar energy on campuses

In this paper, a wireless power transmission (WPT) using resonant magnetic coupling for mobile phone charger is presented. Solar energy was used as the energy source to address the scarcity of non-renewable energy sources and tackles the constraints of wired charging technology such as lack of universal electrical standard, untidiness and inconvenience of wires and wires' wear and tear. The system includes PV panels and battery, oscillator, transmitting coil and receiving coil and rectifier. Proteus 8.1 was used to simulate before implementing in the hardware. The resonant magnetic coupling resonated at 800 kHz ± 10 kHz. The maximum distance to charge a mobile phone was 4 cm at 3.7 V. All the objectives are achieved within the limited time frame. The significance of the project can help to eradicate the use of wires and the need of power plugs. The
future research includes the study of efficiency, coil design, system with multiple loads.
