“…The identified low energy output to losses in the system. Saeed, et al [14] described temperature, voltage drop, dirt and soil, shading, mismatch and inverter as major contributor to over 30% losses associated with grid connected solar PV system. In determination of number of solar PV module, Mevin, et al [15] applied 30% losses in equipment sizing which ultimately increased number of modules required for the proposed plant.…”

Electrification of Faculty of Engineering (FOE) located in Choba Campus in University of Port Harcourt is often realized through distribution network from Port Harcourt Electricity Distribution Company (PHEDC). FOE buildings, each consists of two floors with basement, academic staff offices, administrative rooms and public facilities. Huge sum of money is spent daily to run generators and noise pollution has come to live with us. Nigeria however has immense exposure to solar radiation all through the year. It has highest daily solar radiation of 7.0KWh/m 2 /day and lowest of 3.5KWh/m 2 /day. Choba has average radiation of 4.55kWh/m 2 /day and temperature of 27.23 0 C. Choba is at 4 0 49'27'' North latitude and 7 0 2'1'' East longitude and altitude (elevation) of 20m (64ft). Load profile for FOE was carried out to determine the number of solar panels and inverter rating. Monthly average radiation was obtained from Nigeria meteorological agency between January 2014 to December 2018.The proposed PV system plant capacity is estimated at 100kW based on estimated load profile. Various tools such as system yield factor, capacity utilization factor, performance ratio were used in carrying out performance of 100kW PV system. Plots of I-V characteristics at constant irradiance, P-V characteristics at constant temperature and irradiance and efficiency curve of P-V panels were obtained. The PV is expected to meet 123,228.38kWh annual load demand for FOE, using PVsyst software. This supply period of electricity is between official hours of 8am to 4pm daily and estimated that annual DC energy generated from the system is 126619kWh/year, whereas available energy exported is 121914kWh/year.

This chapter presents the performance of a 20 MWp grid-connected PV system installed in a harsh environment, Adrar in the South of Algeria. The results were monitored over a period of 1 year, from January 2018 to December 2018. The PV system assessment includes final and reference yields, system efficiency, performance ratio, capacity factor, and total system losses. The total yearly energy delivered to the grid was 35892.22 MWh, and the monthly average reference and final yields of the system are in the range 5.92-8.1 (h/day) and 4.39-5.56 (h/day), respectively. Furthermore, the annual average daily PV system efficiency, performance ratio, capacity factor, and total losses were 10.82%, 71.71%, 20.76%, and 2.04 h/day, respectively.

“…The economic advantage of the PV investments has been investigated in several works [3][4][5][6] under different viewpoints. In [3] the determinants of investment risk in the PV industry was analyzed, and alternative business plans were evaluated in order to quantify how Net Present Value (NPV) varies according to different parameters.…”

“…In [3] the determinants of investment risk in the PV industry was analyzed, and alternative business plans were evaluated in order to quantify how Net Present Value (NPV) varies according to different parameters. Edalati et al [4] studied the technical and economic feasibility of a 10 MW p grid-connected PV power plant located in Iran, having performed a comparison of profit expectations in different cities. The feed-in tariff (FIT) profit of a 5 kW p photovoltaic power plant, considering an annual update of the tariff with a 30% reduction during the second decade of the investment, has been studied by Bakhshi and Sadeh [5].…”

Grid-connected low voltage photovoltaic power plants cover most of the power capacity installed in Italy. They offer an important contribution to the power demand of the utilities connected but, due to the nature of the solar resource, the night-time consumption can be satisfied only withdrawing the energy by the national grid, at the price of the energy distributor. Thanks to the improvement of storage technologies, the installation of a system of battery looks like a promising solution by giving the possibility to increase auto-consumption dramatically. In this paper, a model-based approach to analyze and discuss the performance and the economic feasibility of grid-connected domestic photovoltaic power plants with a storage system is presented. Using as input to the model the historical series (2008–2017) of the main ambient variables, the proposed model, based on Stochastic Hybrid Fault Tree Automaton, allowed us to simulate and compare two alternative technical solutions characterized by different environmental conditions, in the north and in the south of Italy. The performances of these systems were compared and an economic analysis, addressing the convenience of the storage systems was carried out, considering the characteristic useful-life time, 20 years, of a photovoltaic power plant. To this end the Net Present Value and the payback time were evaluated, considering the main characteristics of the Italian market scenario.
