Solar panels convert sunlight into electricity by encapsulating and laminating solar cells.
1. The emergence of the concept of solar panels
Da Vinci made related predictions in the 15th century, followed by the emergence of the world’s first solar cell in the 19th century, but with a conversion efficiency of only 1%.
2. Composition of solar cells
Most solar cells are made of silicon, which is the second most abundant resource in the Earth’s crust. Compared to traditional fuels such as oil and coal, it does not cause environmental and human health problems, including carbon dioxide emissions that lead to climate change, acid rain, air pollution, smoke, water pollution, rapidly filling waste treatment plants, as well as habitat damage and accidents caused by oil spills.
3. Solar energy is a free and renewable resource
The use of solar energy is a free and renewable green resource that 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 it consumes throughout the year (approximately 120 terawatts).
4. Utilization of solar energy
Solar panels and rooftop solar water heaters are different. Solar panels convert solar energy into electricity, while solar water heaters use the heat of the sun to heat water. The common feature of the two is environmental protection.
5. Installation cost of solar panels
The initial installation cost of solar panels may be relatively high, but there may be some government subsidies. Secondly, with the development of the economy, the manufacturing and installation costs of solar panels will be decreasing year by year. Just make sure they are clean and not obstructed by anything. Sloping roofs require less cleaning as rainwater helps remove dirt.
6. Post maintenance cost of solar panels
Maintenance of Disheng solar panels is almost unnecessary. Just make sure that the solar panels are clean and not obstructed by anything, and the power generation efficiency will naturally not be affected. Sloping roofs require less cleaning as rainwater helps remove dirt. Secondly, if glass solar panels have a lifespan of 20-25 years, it does not mean they cannot be used, but their power generation efficiency may decrease by about 40% at the beginning of purchase.
7. Working time of solar panels
Crystal silicon solar panels generate electricity outdoors in the sunlight, and even when the sunlight is not strong, they can generate electricity. But on rainy days and nights, it does not work because there is no sunlight, but the excess electricity generated can be stored using batteries.
8. Potential issues with solar panels
Before installing solar panels, you should consider the shape and inclination of the roof, as well as the location of the house itself. It is important to keep the panel away from shrubs and trees for two reasons: they may obscure the device, and branches and leaves may scratch the surface, thereby reducing its performance.
9. Solar panels have a wide range of applications and scenarios
Solar panels can be used in buildings, monitoring, roads, bridges, and even spacecraft and satellites. Some portable solar charging panels can even be used in places such as mobile phones and computers.
10. Solar panel reliability
Even under the harshest conditions, photovoltaic systems can maintain power supply. In contrast, traditional technologies often cannot provide electricity at the most critical time.
