“…The main compensation of Nanofluid is high heat capacity and thermal conductivity [21]. While the drawbacks are pumping processes and total change in flow regime ]22[.Many researchers applied methods for improving the performance of PV\T [23][24]. Many researchers have studied PV\T their application and cooling methods summarized in Table (1).…”

Role of photovoltaic-thermal collector in providing heat and power was revealed.• The profitability of utilizing photovoltaicthermal solar systems was explored. • Solar collector efficiency decreases the cell temperature rise and dust existence. • The state of art of the solar systems and recent advancements were included. • The cooling techniques of the solar photovoltaic soar systems were covered.A solar thermal collector is one of the most popular applications of solar energy.It is a photovoltaic (PV) cell system with a thermal collector system, this system is utilized in the production of electrical energy and many applications. The system is able to produce electrical energy directly from the sunlight using the photoelectric effect. Meanwhile, it also extracts heat from the PV and heats the fluid (airflow) inside the collector. In this review, the solar PV system and solar thermal collectors are discussed. Usually, solar collectors are exposed to damage and their efficiency decreases when the temperature rises. Need constant cooling.In addition, the methods utilized to cool the solar collector are presented, including cooling with air, water, and others methods. It has been shown that the water-based cooling system was at a rate of 48%, while the air-based cooling system was at a rate of 26%, and that cooling by other methods was at a rate of 26%. These methods were applied to the enhancement of the photovoltaic cell efficiency under different conditions. The study revealed the important role being played with the application of solar energy.

“…In Thailand, the number of the installed PV module was booming due to its low cost and the Government policy on green and sustainable energy. In some cases, for example, use of PV-air conditioner might reduce over 75% of grid electrical power for airconditioning in office building during daytime [1][2][3]. However, in hot country such as Thailand, the PV module temperature might reach 70 o C or more in the afternoon then the electrical efficiency was reduced significantly and only 75% or less of the power at standard condition could be generated [4][5][6][7], then many approaches to control the module temperature were presented.…”

This paper proposed a new function of photovoltaic thermal (PVT) module to produce nocturnal cool water not just only generating electrical power and hot water during daytime. Experimental tests were carried out under Chiang Mai tropical climate with a 200 Wp monocrystalline PVT module having dimensions of 1.601 m × 0.828 m connected with two water tanks each of 60 L taken for hot and cool water storages. The module was facing south with 18 o inclination. The electrical load was a 200 W halogen lamp. From experiments, by taking the module as a nocturnal radiative cooling surface, the cool water temperature in the cool storage tank could be reduced 2 o C-3 o C each night and the temperature could be reduced from 31.5 o C to 22.1 o C within 4 consecutive days. The cool water at approximately 23 o C was also used to cool down the PVT module from noon when the PVT module temperature was rather high, and then the module temperature immediately dropped around 5 o C and approximately 10% increase of electrical power could be achieved. A set of mathematical models was also developed to predict the PVT module temperature and the hot water temperature including the cool water temperature in the storage tanks during daytime and nighttime. The simulated results agreed well with the experimental data.

“…Therefore, it is vital to minimize the self-consumption of the solar charge controller because it has been connected to the system for 24 hours. In [2] [5] [7] [9] [19] and [20], the consumption of LED, LCD and IC impacts is more than 30 mA. The nominal voltage of the battery is 12V, so the total energy consumption of the solar charge controller is -𝑇𝑜𝑡𝑎𝑙 𝐸𝑛𝑒𝑟𝑔𝑦 𝐶𝑜𝑛𝑠𝑢𝑚𝑝𝑎𝑡𝑖𝑜𝑛 = 𝑉 𝑋 𝐼 𝑋 24 𝐻𝑟𝑠 = 12𝑉 𝑋 0.03𝐴 𝑋 24ℎ𝑟𝑠 = 0.36𝑊𝑋 24 ℎ𝑟𝑠 = 𝟖.…”
