Modeling and experimentation of monocrystalline photovoltaic module performance with flat mirror reflectors in Elbida climate conditions

Abstract EN

The purpose of this paper is to give an outline of a method for optimizing solar panel performance in the presence of solar tracking mirrors in order to maximize energy output.

Under the climate circumstances of Elbieda, as well as to examine the primary influence of cell temperature on the performance of mono-crystalline modules with a mirror reflector.

For the photovoltaic system with flat mirror reflectors, a mathematical model has been developed to predict solar radiation.

The components of solar radiation [global, direct, and diffuse], geometric factors, and geographical features of a PV installation are included in the model.

In addition, to calculate the temperature of the cells.

Where meteorological parameters such as ambient temperature, slope radiation, and wind speed are used to apply the energy balancing technique.

On a specific day in July, the tests were carried out.

The findings of the modeling simulation were compared to measurements taken during two periods, with and without the use of a reflector.

For a traditional PV system and a PV reflector system, the coefficient of determination (R2) was 98.7% and 97%, respectively.

In both situations, the mean bias error (MBE) values were less than 1%.

The root means square error (RMSE) was 26.774%, 36.914% respectively in both cases.

The estimated results were validated by comparing the results obtained for the measured slope surface irradiance and the measured unit cell temperature.

The addition of flat mirror reflectors to successfully listed PV panels was extremely effective in detecting solar irradiance, resulting in positive findings of fitted parameters.
