In this study, a new theoretical approach (new mathematical model) encompasses the heat transfer and energy balance is proposed to determine the performance of the photovoltaic thermal (PVT)-thermoelectric (TE) air collector (PVT-TE) hybrid system. The hybrid system consists of PV panel and TE modules that can improve the energy efficiency of the system. Theoretical and experimental studies were studied using energy analysis to predict the output temperature (T o ) and PV temperature (T p ).To evaluate system performance, a theoretical model is developed using the energy balance analysis of this hybrid system. The matrix inverse method is used to complete the theoretical model. Effect of mass flow rate and radiation intensity is also being investigated. Experimental studies were carried out at the air flow rate of 0.02 kg/s, 0.04 kg/s and 0.07 kg/s, and radiation intensities are in the range of 342-922 W/m 2 . The results of the experimental and theoretical studies show that the percentage of errors between the theory and the experimental value of T o and T p are 1.14% and 1.75% respectively. ABSTRAK Dalam kajian ini, suatu pendekatan teori baharu (model matematik baru) merangkumi pemindahan dan keseimbangan tenaga dicadangkan untuk menentukan prestasi sistem hibrid pengumpul udara fotovoltan (PV)-termoelektrik (TE) (PVT-TE). Sistem hibrid terdiri daripada panel PV dan modul TE yang boleh meningkatkan kecekapan penukaran tenaga sistem. Kajian teori dan eksperimen dikaji menggunakan analisis tenaga untuk meramal suhu keluaran (T o ) dan suhu PV (T p ). Untuk menilaiprestasi sistem, satu model teori dibangunkan dengan menggunakan analisis keseimbangan tenaga bagi sistem hibrid ini. Kaedah songsangan matriks digunakan untuk menyelesaikan model teori tersebut. Kesan terhadap kadar aliran udara dan keamatan sinaran juga disiasat. Kajian eksperimen juga dilakukan pada kadar aliran udara 0.02 kg/s, 0.04 kg/s dan 0.07 kg/s, dan keamatan sinaran dalam julat 342-922 W/m 2 . Keputusan kajian eksperimen dan teori menunjukkan bahawa peratusan ralat antara model pengiraan teori dan nilai eksperimen untuk T o dan T p masing-masing adalah 1.14% dan 1.75%.

This work presents performance analysis of a novel multi-pass solar air collector with perforated fins (MPSACF) in winter conditions, Ankara province, Turkey. The aim of this work is to experimentally test and compare the performance of the two different design of solar collectors in the same climatic conditions. In addition, a double-pass solar air collector without fins (DPSAC) at the same absorber area was manufactured and tested as a control group. The total absorber area of both solar collectors is 0.325 m2. Thermal effects for performance improvement of the collectors have been designated. Average thermal efficiency values of DPSAC and MPSACF were calculated as 47.85% and 51.86%, 67.10% and 72.86%, respectively in experiments performed at 0.0069 kg/s (0.7 m/s air velocity) and 0.0087 kg/s (0.9 m/s air velocity) mass flow rates. Exergy efficiency of DPSAC and MPSACF were 2.10-17.12% and 8.74-23.97%, respectively. Coefficient of performance(COP) values were ocomputed 4.63 and 4.94, 3.18 and 3.48 respectively in experiments performed at 0.0069 kg/s and 0.0087 kg/s mass flow rates. Although the MPSACF has high efficiency values, COP values are lower due to the presence of dual fans. Because of their high thermal efficiency, both collectors can be effectively practiced for applications such as preheating, space heating and ventilation, greenhouse heating and product drying©2019.

“…Solar energy is a clean energy which has the potential to meet a significant proportional of the world's energy needs (Fudholi et al, 2014b;2014c). It can be broadly classified into two systems; thermal energy system which converts solar energy into thermal energy, and photovoltaic (PV) energy system which converts solar energy into electrical energy (Ibrahim et al, 2014;Fudholi et al, 2013a;2013b).…”

Solar energy is a clean energy, renewable, and available for the long term. The tool used to convert the energy generated from the intensity of sunlight into electricity is photovoltaic panels. However, due to the high cost and low efficiency, the use of the energy is still kind small compared to other types of energy sources. Thus, the need for an effective and flexible models, which resemble the characteristics of the actual photovoltaic (PV), so that we can perform simple manipulation of some data to figure out how to get the maximum performance possible. The characteristic of the solar panel output is specific and non-linear, it depend on the solar irradiation and the temperature of the solar panel. Because of it, it makes us difficult to get the Maximum Power Point (or abbreviated MPP) of the solar panels. Approach: Therefore, to solve these problems required the modeling of the solar panel for design and simulate the algorithms of Maximum Power Point Tracking (MPPT) to maintain the working point of solar panels fixed on the MPP. Overall, the designed system results carried are running well. The increase in the average value of the output voltage by 17%, from an average of 11.6 V before installation into 13.94 V after installation MPPT system. It also occurs in output power with an increase of 28%, from an average of 35.13 W before installing system MPPT into 48.9 W after installation MPPT system. The temperature effect on module voltage and output power before and after installation of the MPPT system that after the installation of the MPPT system, the voltage output of photovoltaic modules can be maintained around the desired maximum value that's equal to 12 V. But there was a drop in output power value compared to the prior installation MPPT system. This is caused by the output current value that cannot accommodate the value of the output voltage. So that the value of the output current is enough to produce the maximum output power is needed quantities corresponding load.
