Abstract
In Nigeria, grid connected solar based system are not common as most connections are stand-alone This work analyze costing of proposed solar photovoltaic systems performance for Faculty of Engineering (FOE), University of Port Harcourt. With unit cost of grid power at ₦48.35/kWh based on MYTO sets for a 10-year tariff path with bi-annual minor reviews for Port Harcourt Electricity Distribution Company (PHEDC), it is expected that FOE spends ₦5,894,541.9 annually on electricity consumption when the supply is fully dependent on PHEDC.it is worthy to note that the generation source is fossil fuel which is harmful to the ecosystem. If however solar photovoltaic source as an alternative means of power generation is used at a unit cost of electricity production from proposed PV plant at the rate of ₦75/kWh, simple payback time is 7 years and 4 months and performance ratio is 81.8%. The proposed PV plant is expected to meet power requirement of FOE efficiently and reliably. Within life span of 25 years, 907.666 tons of carbon that would have wreaked havoc to the environment would have been saved. Various losses were also considered and calculated accordingly. Effect of weather condition on the overall performance was also discussed. The proposed PV plant is viable and will address the lingering energy crisis in the faculty.
