“…The parameters of the PVT and the weather data were mainly taken from the experiment conducted by Bahaidara et al [21] in Saudi weather (Dhahran). There were missing information in the experiment about some characteristics of the PVT so some parameters which included UL, UT and UtT were assumed based on Duebey [19] theoretical model.…”

Research into photovoltaic thermal systems is important in solar technologies as photovoltaic thermal systems are designed to produce both electrical and thermal energy, this can lead to improved performance of the overall system. The performance of photovoltaic thermal systems is based on several factors that include photovoltaic thermal materials, design, ambient temperature, inlet and outlet fluid temperature and photovoltaic cell temperature. The aim of this study is to investigate the effect of photovoltaic thermal outlet water temperatures and solar cell temperature on both electrical and thermal efficiency for different range of inlet water temperature. To achieve this, a mathematical model of a photovoltaic thermal system was developed to calculate the anticipated system performance. The factors that affect the efficiency of photovoltaic thermal collectors were discussed and the outlet fluid temperature from the photovoltaic thermal is investigated in order to reach the highest overall efficiency for the solar cooling system. An average thermal and electrical efficiency of 65% and 13.7%, respectively, was achieved and the photovoltaic thermal mathematical model was validated with experimental data from literature.

“…In addition, in the same way as Ramkumar et.al [5], which carried out the experiment in five days and acquired data in the morning from 9:00 AM to 4:00 PM in the evening. Also, in [3] the measurements were performed during the month of February and recorded data from 9:00 AM to 4:00 PM. Therefore, due to the arguments mentioned before, the behavior of both systems were analyzed in seven days from 8 am.…”

This project shows a photovoltaic hybrid system (PHS) that follows the sun using electronic and mechanic devices and reduces the solar panel’s temperature with water in order to increase the energy obtained. The system was designed and implemented with a 1-axis solar tracker system and a water cooling system. PHS allows solar radiation beams to fall almost perpendicularly and decreases the temperature of the solar panel. Finally, its performance is compared against a traditional fixed photovoltaic system (FPS) oriented at 15° facing south. Experiments were made during only seven days in a year between December 1st and December 19th of 2017 in Guadalajara de Buga, Valle del Cauca, Colombia. Tests consisted of using the same electric loads at 20%, 40% and so on until 100% of the total power capacity of the solar panels. Results points out that electrical efficiency of the PHS increased 5.03% compared to the FPS on the same environmental conditions. Finally, PHS shows daily additional average power between 37% and 40% when it is loaded with electric loads at 80% and 100%.

“…Sheet and tube PVT is the most common configuration where PV cells are fixed with flat plat collector. An experimental study showed that a reduction in PV temperature by 20% led to an increase in the electrical efficiency by 9% [27]. The main components of a PVT system are the PV cells to produce electricity, channels for the fluid, absorber plate and thermal insulation to minimize the heat loses as shown in Fig.…”

The aim of this investigation is to evaluate the recent advances in the field of solar absorption cooling systems from the viewpoint of solar collector types. A review in the area of photovoltaic thermal (PVT) absorption cooling systems is conducted. This review includes experimental and computational work focusing on collector types and their efficiencies and performance indicators. Compared to vapour compression air conditioning systems, 50% of primary energy was saved by using solar absorption cooling systems and 10-35% maximum electrical efficiency of PVT was achieved. This review shows that Coefficient of Performance (COP) for solar cooling systems is in the range of 0.1-0.91 while the thermal collector efficiencies are in the range of 0.06-0.64. The average area to produce cooling for single effect absorption chillers for experimental and computational projects is 4.95 m 2 /kW c and 5.61 m 2 /kW c respectively. The specific area for flat plat collector (FPC) is in the range of 2.18-9.4 m 2 /kW c , while for evacuated tube collector (ETC) is in the range of 1.27-12.5 m 2 /kW c. For concentrated photovoltaic thermal collector (CPVT) and PVT, the average area to produce cooling for solar absorption chillers are 2.72 m 2 /kW c and 3.1 m 2 /kW c respectively.
