Solar Thermal Panels for Generating Electricity

All over the world, the focus is on using alternative energy instead of fossil fuels because they will be depleted in the coming years and pollute the environment. After all, they produce greenhouse gas emissions. There are many alternative energy sources, but solar energy is the best because it is the basis of all sources. The purpose of this research is to generate electricity from solar energy with its different application there are two main types which divide into photovoltaic panels which depend on the light of the sun, solar heat panels contain: parabolic trough, solar tower, and non-aqueous heating devices which depend on thermal from the sun and each of them contains its specific structure and material. From the previous research, Photovoltaic panels generate electricity from sunlight with high efficiency and high cost but low cost compared to another ordinary way of generating electricity. Photovoltaic divided into other types, for example, CPV which use mirrors with a special type of silicon and there are also thin-film solar panels, Polycrystalline and Mono Monocrystalline which are low efficiency compared to solar heat panel which generates electricity by absorbing the heat from the sun with mirrors which collect heat at a certain point, then heat the liquid and transfer it to the water for steam, this steam converts the turbines connected to the generator that transfers mechanical energy into electrical energy. The cost depends on the cheap materials were used in it, and among the previous research, the best application was the solar thermal power plant as it can overcome its defects. For measuring the output of different panels different devices, laws, and theories to select the parameters focus on the Iv of each PV.
