    An experimental study on energy generation from photovoltaic-thermal hybrid systems

    Industry 4.0, Vol. 5 (2020), Issue 2, pg(s) 76-78

    Solar energy is one of the leading renewable energy sources because of its great potential, affordability of the individual system prices, zero emission and no noise emission. 21st century will be based on renewable energy sources, with strict environmental measures, primary energy use will mainly consist of a combination of (different) clean energy sources among which solar energy will play a leading role. Two technologies for harnessing the energy of the sun are photovoltaic cells (PV) and solar collectors. Photovoltaic cells (PV) exploit the visible part of the spectrum while solar collectors use the infrared part. Combining these two technologies into one provides a system that produces electricity and heat at the same time using all parts of the solar spectrum. These systems are known as photovoltaic thermal systems or PV/T. This paper presents the description of these systems and methods of application. Among this, this paper gives description of experimental PV/T installation at Faculty of Mechanical Engineering in Banja Luka.

    In this paper, we design and simulate a 20 kW solar on grid power charging unit for electric vehicles at Al-Hussein Bin Talal University (AHU)/Maan-Jordan by using a Bluesol 3.0, Sketch Up 2018 software.
    Two scenarios are considered; one where number of vehicles is five in the interval (8 am – 12 pm) & five vehicles in the interval (12 pm – 4 pm) and time of charge half of battery capacity four hours and the second scenarios where number of vehicles is eight in the interval (8 am – 12 pm) & eight vehicles in the interval (12 pm – 4 pm) and time of charge half of battery capacity four hours. We conclude that the system is efficient and very useful to the electric vehicles users in the university. In addition, the system is reducing the CO2 emissions annually from generating power by 28.4 tons of CO2.
