Solar panel is a part of the whole solar power system, it is a kind of device that can convert the energy contained in the energy-containing particles of the sunlight: the energy in the photons into electricity, the overall structure is composed of a number of independent, rectangular shaped photovoltaic cells, in order to realize the overall combination of installation and power generation.
Solar panels can be used in a wide range of applications, including power supply for seagoing vessels, residential solar power supply and commercial solar power systems. At the same time, the special power generation principle of solar panels makes it possible to supplement the power supply of large buildings and serve remote areas. If a power plant consisting of thousands of solar panels is constructed, it can also be used to provide basic daily electricity for cities.
Solar panels can utilize photovoltaic cells to collect light energy, a clean and renewable source of energy, and then realize the process of converting light energy into electricity. The photovoltaic cell itself consists of two layers of semiconductor material responsible for providing positive and negative charges, the most common material layer being silicon. When sunlight hits the panels, photons are absorbed by these photovoltaic cells, and the electrons on the panels are excited from a lower energy state to a higher energy state, thus realizing free movement on the panels.
These free-moving electrons will be pulled by the photovoltaic cells into a directional current and induce a built-in electric field, thus realizing the whole process of converting light energy into electricity through the photovoltaic effect. It is important to note that although solar panels rely on light energy to generate electricity, they can also react to sunlight reflected from the atmosphere and clouds to generate a small amount of electricity on cloudy days.
Installing solar panels allows for off-grid living. When living far from the beaten track in an area not served by the main power grid, installing solar panels can avoid the high cost of having to re-Route wires from the main power grid. And it can meet the average household’s daytime electricity needs while still having a surplus, and this excess power that is generated will be stored for night-time use.
Installing solar panels can reduce greenhouse gas emissions. Solar energy is an absolutely clean and renewable energy source, and the process of converting light energy into electricity does not produce waste or greenhouse gases, so promoting the use of solar panels for power generation in homes, businesses, and cities helps to protect the ozone layer over the world and the global ecosystem.
Best of all, After the purchase and installation of the solar panels, the electricity generated over the next 15 to 25 years is completely free of charge! Not only that, but you can even make a profit by selling the excess electricity generated by your solar panels to a power company!
The problem of reduced energy conversion efficiency in a completed photovoltaic power generation system is so fatal that we should have standardized sockets on the back of each solar panel so that its output can be combined with other panels to form a complete power generation system.
The solar panel should be installed with the fixed bracket facing south if it is installed in the northern hemisphere and facing north if it is installed in the southern hemisphere. And the tilt angle of the solar panel should be about 15 degrees smaller than the dimension of the installation site in summer and about 25 degrees larger than the dimension of the installation site in winter.
