Solar panels convert sunlight into electrical energy by encapsulating solar cells in a laminated layer.
1. The emergence of the concept of solar panels
Da Vinci made a related prediction in the 15th century, followed by the emergence of the world's first solar cell in the 19th century, but its conversion efficiency was only 1%.
2. Components of solar cells
Most solar cells are made from silicon, which is the second most abundant resource in the Earth's crust. Compared to traditional fuels (petroleum, coal, etc.), it does not cause environmental damage or human health problems, including carbon dioxide emissions that contribute to climate change, acid rain, air pollution, smog, water pollution, rapidly filling waste disposal sites, and damage to habitats and accidents caused by oil spills.
3. Solar energy is a free and renewable resource
Using solar energy is a free and renewable green resource that can reduce carbon footprints. Solar energy users can save up to 75 million barrels of oil and 35 million tonnes of carbon dioxide annually. In addition, a large amount of energy can be obtained from the sun: in just one hour, the Earth receives more energy than it consumes in an entire year (approximately 120 terawatts).
4. Utilisation of solar energy
Solar panels are different from solar water heaters used on roofs. Solar panels convert solar energy into electrical energy, while solar water heaters use the sun's heat to heat water. What they have in common is that they are environmentally friendly.
5. Solar panel installation costs
The initial installation costs for solar panels may be relatively high, but there may be some government subsidies available. Secondly, as the economy develops, the manufacturing and installation costs of solar panels will decrease year by year. Just make sure they are clean and not obstructed by anything. Sloped roofs require less cleaning, as rain helps to remove dirt.
6. Post-installation maintenance costs for solar panels
Maintenance of XinDongKe solar panels is virtually non-existent. Simply ensure that the solar panels are clean and not obstructed by any objects, and their power generation efficiency will not be significantly affected. Sloped roofs require less cleaning, as rainwater helps remove dirt. Additionally, the lifespan of glass solar panels can reach 20–25 years. This does not mean they cannot be used, but their power generation efficiency may decrease by approximately 40% compared to when they were first purchased.
7. Solar panel operating time
Crystalline silicon solar panels generate electricity outdoors under sunlight. Even when the sunlight is not strong, they can still generate electricity. However, they do not work on cloudy days or at night because there is no sunlight. However, the excess electricity generated can be stored in batteries.
8. Potential problems with solar panels
Before installing solar panels, you should consider the shape and slope of your roof and the location of your house. It is important to keep the panels away from bushes and trees for two reasons: they may block the panels, and branches and leaves may scratch the surface, reducing their performance.
9. Solar panels have a wide range of applications
Solar panels can be used in buildings, surveillance, road bridges, and even spacecraft and satellites. Some portable solar charging panels can even be used with mobile phones, computers, and other devices.
10. Solar panel reliability
Even under the most adverse conditions, photovoltaic systems can maintain power supply. In contrast, traditional technologies often fail to provide power when it is most needed.
