Photovoltaic power generation bracket spraying method

Can spray cooling be applied to solar photovoltaic cells?

In this study, spray cooling is applied to the cooling of photovoltaic cells, and the mathematical model of a solar photovoltaic power generation system is established by considering the power consumption of the cooling system. The net output power and electrical efficiency of the system are compared under different cooling modes.

What are the different cooling methods used in PV solar cells?

The cooling methods used are described under four broad categories: passive cooling techniques, active cooling techniques, PCM cooling, and PCM with additives. Many studies made a general review of the methods of cooling PV solar cells, especially the first three methods.

Does forced-convection cooling improve power generation performance of PV cells?

Mazón-Hernández et al. [ 9 ]compared the effects of forced- and natural-convection cooling on the power generation performance of PV cells and found that the PV cell panel temperature could be further reduced by 10–16 °C and the output power increased by 3%–5% when the forced-convection cooling method was used under the same conditions.

How can active cooling improve photovoltaic performance?

The active cooling technique is considered an effective way to improve the photovoltaic performance, but it depends on an external power source, so the external power is deducted from the power produced from the PV cells, reducing the net output power produced from the PV cells.

How to optimize a photovoltaic plant?

The optimization process is considered to maximize the amount of energy absorbed by the photovoltaic plant using a packing algorithm (in Mathematica™ software). This packing algorithm calculates the shading between photovoltaic modules. This methodology can be applied to any photovoltaic plant.

What is the optimum airflow rate for photovoltaic panels?

The results also proved that the optimum airflow rate is 0.055 kg/h. The higher airflow rates do not constitute an additional improvement in the cooling process but rather increase the power required to operate this fan. Khanjari et al. (2016) numerically studied the cooling of photovoltaic panels by PV/T system.
