“…Akinbowale [15], [16] has showed the various thermal parameters that affects the variation of temperature distribution. Similarly Balotaki [17] demonstrated the effectiveness of using solar collector as heat exchanger in process heat applications. It is found from the literature, that the temperature of the solar PV panel can be maintained constant using FW cooling system.…”

Solar Photovoltaic (PV) cells convert an average of 10 to 15% of the incident solar radiation into electricity and remaining energy is wasted as unused heat energy. The p erformance of solar PV is largely dependent on its operating temperature, which is again dependent on solar irradiation. The efficiency of solar PV reduces the higher PV temperature due to charge carrier recombination. The solar PV efficiency drops considerably wit h increasing temperature. Dust deposition on the surface of solar PV cells reduce incident energy and no technology is commercially available to mitigate the problem. The objective of the present work is to enhance the energy conversion efficiency of solar PV by adopting Front Water (FW) cooling technique. The FW cooling technique maintains the cell temperature at Standard Test Conditions (STC) irrespective of ambient air conditions and also washes away dust deposits, thereby providing maximum energy conversion efficiency specified by the cell manufacturer during the operation with increased lifecycle of solar cells. The experiment was carried out on a 100 W solar panel for a period of 2 weeks and data acquisition system with Arduino controller was used to analyze and maintain STC of the panel to obtain maximum power. The mathematical model of the system was analyzed and obtained results were in good agreement with the experimental measurements. The solar PV panel with FW cooling yielded an efficiency improvement of 9% with 17 W of increased power output at Maximum Power Point (MPP). MATLAB Simulink software is used to model t he FW cooling technique. The model is able to predict the power generated by the solar PV cells for the given irradiance with and without cooling. The developed model can now be utilized to design cooling systems for larger installation of solar PV systems.

“…Balotaki et al experimented a multifunctional collector for simultaneous water and air heating. The total collector efficiency was found between 58-74%, while individual water and air heating efficiency ranges were 43-19% and 31-45% respectively [14]. Bhusal et al performed technical and economical investigations on a PTC using an evacuated tube absorber.…”

In this study, a novel non-tracking parabolic trough collector (PTC) is developed and experimentally investigated under North Cyprus climate conditions for residential water heating applications. Within the study, the impact of solar radiation (SR) and water volumetric flow rate (VFR) on the system performance is evaluated based on the testing results. Experiments were performed in the first and third weeks of April in Famagusta, in which SR is limited due to the rain and cloudy sky. The system is tested with water VFRs of 15 L/h and 20 L/h. During the tests, collector inlet/outlet temperatures also water tank, and ambient temperatures were measured. Furthermore, the solar intensity was also measured and recorded. Average SR on PTC surface, during the testing with 15 L/h and 20 L/h, was determined as 654.5 W and 723.3 W respectively. Study results showed that the useful heat gain from PTC was 285.2 W and 233.7 W, for the same order of VFRs. Moreover, the average thermal efficiency of the system was found as 44% and 33% for the VFRs of 15 L/h and 20 L/h respectively.

The flux density distribution and the temperature of the receiver are important parameters to assess the net thermal energy of any Solar Power Concentrator. In the present work, a heliostat field utilizing ganged type of heliostats for process heating application has been designed. A prototype model of the central receiver system consisting of ganged heliostats has been constructed and installed at Pune, Maharashtra, India. A thermocouple method was used to evaluate the total energy focused by the model heliostat system on a flat receiver. The flux density distribution was validated with the ray tracing simulation software 'SolTrace'. The simulated flux density distribution was found to be in agreement with the measured one for a surface normal error of 10 milliradian. A heliostat field having 100 m 2 total mirror area was designed in the north south cornfield layout. This heliostat field was simulated in 'SolTrace' software by considering the surface normal errors as 10 milliradian and the total energy gain was estimated. For the purpose of simulation to investigate the solar flux falling on the receiver, four days of the year were selected. It includes the March equinox, summer solstice, September equinox, and winter solstice.
