Abstract
The output power capacity of solar panels depends on the intensity of light radiation it receives, while the life time depends on the high and low temperatures experienced. The purpose of this study was to examine the effect of light intensity on the output power and efficiency of solar panels. This study applies a direct measurement method using a monocrystalline type solar panel and a polycrystalline type with the same power capacity with a peak capacity of 50 Wp. The research was conducted indoors using lights as light sources by varying the light intensity in the range 2.21-331.01 W/m2 with a distance of 50 cm from the light source from the solar panel. The increase in temperature on the surface of the solar panel can also reduce the power capacity generated, and the monocrystalline type is more resistant to temperature increases than polycrystalline. The efficiency of the solar panel changes when given light with a certain energy, up to the highest intensity of 331.01 W/ m2, with the highest temperature that occurs resulting in an efficiency of 12.84% on the Monocrystalline Panel and 11.95% on the Polycrystalline Panel.
Highlights
A semiconductor material composition in the form of a p-n diode meeting, if it gets a light beam it will cause a flow of electrons in it, so it is called a Solar Cell which can be used as a source of electrical energy
From the observations obtained from the parameter data of the solar cell module
Research conducted with varying light intensities to get the best efficiency value every hour, from the lowest light intensity to high light intensity with 313 and 445 W/m2 with the distance of the light source to the solar cell, by getting the power data generated by the power plant solar
Summary
A semiconductor material composition in the form of a p-n (positive-negative) diode meeting, if it gets a light beam it will cause a flow of electrons in it, so it is called a Solar Cell which can be used as a source of electrical energy. To meet the electron flow capacity as needed, a number of solar cells are combined in a certain area called the solar panel. The transfer of electrons or the so-called current flow between two layers of photovoltaic cells which are opposite in the solar panel due to exposure to sunlight is called the photovoltaic effect. Solar panels are the most effective, sustainable and environmentally friendly power generation system in the world today. Various types of solar panel technologies such as mono crystalline silicon, poly crystalline silicon, amorphous silicon, thin films are the most popular technologies for generating electricity. The performance and efficiency of solar panel modules depend on the electrical parameters and the environment in which they are located [1]
