Solar panels are solar cells that can be converted into electricity by packaging and laminating.
1. The emergence of solar panel concept
Leonardo da Vinci made relevant predictions in the 15th century, followed by the emergence of the world’s first solar cell in the 19th century, but the conversion efficiency was only 1%.
2. Composition of solar cells
Most solar cells are made of silicon, which is the second richest resource in the earth’s crust. Compared with traditional fuels (oil, coal, etc.), it will not damage the environment and human health problems, including carbon dioxide emissions, acid rain, air pollution, smoke, water pollution, rapid filling of waste treatment plants, and the damage and accidents of oil spills to habitats.
3. Solar energy is a free and renewable resource
Using solar energy is a free and renewable green resource, and can reduce the generation of carbon footprint. Solar users can save up to 75 million barrels of oil and 35 million tons of carbon dioxide annually. In addition, a large amount of energy can also be obtained from the sun: in just one hour, the energy received by the earth exceeds the energy consumed throughout the year (about 120 terawatts).
4. Utilization of solar energy
The solar panel is different from the solar water heater used on the roof. The solar panel uses solar energy to convert into electric energy, and the solar water heater uses the heat of the sun to heat water. The common ground of the two is environmental protection.
5. Installation cost of solar panel
The initial installation cost of solar panels may be relatively high, but there may be some government subsidies. Secondly, with the economic development, the manufacturing cost and installation cost of solar panels will decrease year by year. Just make sure they are clean and not covered by anything. Sloping roofs require less cleaning because rain helps remove dirt.
6. Post-maintenance cost of solar panels
Solar panel maintenance is almost unnecessary. Just make sure that the solar panel is clean and not covered by anything, and the power generation efficiency will not be affected. Sloping roofs require less cleaning because rain helps remove dirt. Secondly, if the service life of glass solar panels can reach 20-25 years, it is not that they cannot be used, but their power generation efficiency may be reduced by about 40% at the beginning of purchase.
7. Working time of solar panel
Crystalline silicon solar panels are used to generate electricity in the outdoor sun. When the sun is not strong, they can also generate electricity. However, it does not work in rainy days and at night because there is no sunlight, but it can use batteries to store the extra power generated.
8. Potential problems of solar panels
Before installing solar panels, you should consider the shape and inclination of the roof and the location of the house itself. It is important to keep the panel away from shrubs and trees for two reasons: they may mask the device, and branches and leaves may scratch the surface, thus reducing its performance.
9. Wide range of applications of solar panels
Solar panels can be used in buildings, monitoring, roads and bridges, and even spacecraft and satellites. Even some portable solar charging panels can be used in mobile phones, computers and other places.
10. Solar panel reliability
The photovoltaic system can maintain power supply even under the worst conditions. In contrast, traditional technologies are often unable to provide power at the most critical time.
