    This study focuses on the evaluation of solar panel efficiency used within Port Harcourt environment. A major factor affecting the efficiency of solar panels is the difference in region or weather and the ability of the solar panel to convert incident radiation into electrical energy. Solar panels have varying efficiency levels under different weather conditions. Most times solar panels fall short of expected efficiencies. It is therefore important to have adequate knowledge of the performance characteristics of a panel under specific weather to ensure maximum output. For this research work, the panel evaluated is a 125W Polycrystalline solar panel made of Gallium Arsenide. The efficiency of the panel is calculated and recorded. The weather data for Port-Harcourt is collected from the center for data collation Rivers State University. The peak radiation value obtained from the weather data for the year under consideration is used to evaluate the efficiency and Genetic Algorithm is used to determine the optimal parameter of the cells making up the panel to obtain an optimized cell to improve the efficiency of the panel. To do this the cell initial properties is extracted and tabulated genetic algorithm is then used to improve this properties achieving better efficiency in the process.

    A Comparative Study of on and off Grid Tied Integrated Diesel Solar PV Generation System

    This paper presents a proposed hybrid system based on diesel generator and solar photovoltaic (PV) as an effective option to power a small remote community. The cost of running diesel generator speedily due to erratic power supply in a small remote community that is not grid connected is highly expensive and not environmentally friendly. A solar PV was used to reduce or augment the continuous diesel generator sets, resulting in reduced cost of operation and maintenance. A proper solar radiation data and sizing based on the specification of the PV system and battery bank was done. In addition, a comparative study was carried out considering two scenarios of the proposed model system. In the first scenario, the diesel generation, solar PV system was treated as autonomous (or standalone). In the second scenario, the proposed model system was connected to the grid system. It is discovered that powering the small remote community with the proposed hybrid system is much more beneficial and encourages competition with other conventional energy sources, because it minimizes both operating costs and pollutants emissions. Furthermore, analysis results obtain from HOMER software shows that is promising to implement the on-grid system.
