In this paper, a feasibility study has been done utilizing real time solar irradiance data for a 1MW grid-connected PV system in Qassim region in the middle of Saudi Arabia. The analysis has been done using both technical and economic indicators. Technical performance indicators are; Yield Factor, Capacity Factor and Performance Ratio. Economic indicators are; Levelized cost of energy and simple payback time. The simulation results show high energy productivity, and both technical and economic indicators are high compared with similar systems in different countries. Also, the greenhouse gas emission reduction has been estimated. The prices of PV modules and balance of system components are up to date. The analysis results proved the viability of the proposed system supposing there is no any governmental incentives or grants which could make big difference..

The rapid development in Internet technology and its big popularity has led some universities around the world to incorporate web-based learning in some of their programmes. The present paper introduces a comprehensive survey of the publications about using remote laboratories in electrical engineering education. Remote laboratories are web-based, real-time laboratories that enable students to measure and control the measurements remotely in their own time. The survey highlights the features of many recent remote laboratories and demonstrates the software and networking technologies used. The paper provides a comprehensive overview on several aspects related to remote laboratories development. The paper concentrates on the publications appearing during the last decade. The review is arranged according to the area of specialisation, then chronologically.

The Kingdom of Saudi Arabia (KSA) is considered one of the countries with the highest consumption of electric energy per capita. Moreover, during the period of 2007–2017, the consumption rate increased from 6.9 MWh to 9.6 MWh. On the other hand, the share of residential electricity consumption in the KSA constitutes the biggest portion of the total electric consumption, which was about 48% in 2017. The objectives of this work were to analyze the exergy and assess the economic and environmental impacts of energy consumption in the residential sector of the Qassim region to determine potential areas for energy rationalization. The consumption patterns of 100 surveyed dwellings were analyzed to establish energy consumption indicators and conduct exergy analysis. The performances of different consuming domestic items were also examined, and energy efficiency measures are proposed. The average yearly consumption per dwelling was determined, and the total energy and exergy efficiencies are 145% and 11.38%, respectively. The average shares of lighting, domestic appliances, water heaters, and air conditioning from the total yearly energy consumption were determined.
