10 Things You Must Know About Solar Panels

1. The emergence of the solar panel concept

Leonardo da Vinci in the 15th century has put forward related prophecies, followed in the 19th century the world's first solar cell sheet appeared, but the conversion efficiency is only 1%.

2. Components of solar cell wafers

Most solar cell wafers are made from silicon, which is the second most abundant resource in the earth's crust. As opposed to traditional fuels (oil, coal, etc.), it does not damage the environment and human health issues including carbon dioxide emissions that contribute to climate change, acid rain, air pollution, smog, water pollution, rapidly filling waste disposal sites, and habitat destruction and accidents from oil spills.

3. Solar energy is a free and renewable resource

Going solar is a free renewable green resource and reduces your carbon footprint. Solar users can save up to 75 million barrels of oil and 35 million tons of carbon dioxide per year. In addition, a great deal of energy can be harvested from the sun: in just one hour, the Earth receives more energy than it consumes in an entire year (about 120 terawatts).

4. Utilization of solar energy

Solar panels are not the same as solar water heaters used on rooftops. Solar panels utilize solar energy to convert into electricity, and solar water heaters utilize the sun's heat to heat water, and the common point between the two is environmental protection.

5. Solar panel installation cost

The initial installation cost of solar panels may be relatively high, but there may be some government subsidies. Secondly, as the economy grows, the cost of manufacturing solar panels as well as the cost of installing them will decrease every year. Just make sure they are clean and not shaded by anything. Sloped roofs require less cleaning as rainwater helps to remove the dirt.

6. Solar panel maintenance cost

Dyson solar panels maintenance is almost unnecessary. Just make sure that the solar panels are clean and not blocked by anything, and the power generation efficiency will naturally not be affected much. Sloped roofs require less cleaning as rainwater helps in removing the dirt. Secondly if they are glass solar panels can last up to 20-25 years, that's not to say that they won't work, just that they may be about 40% less efficient at generating electricity than when they were first purchased.

7. Solar panel working time

Crystalline silicon solar panels generate electricity all outdoors under the sunlight, and when the sunlight is not strong, it is also able to generate electricity. However, on cloudy and rainy days as well as at night, it does not work because there is no sunlight, but the excess power generated can be stored in batteries using batteries.

8. Potential problems with solar panels

Before installing solar panels, you should consider the shape and tilt of the roof as well as the location of the house itself. It is important to keep the panels away from shrubs and trees for two reasons: they may shade the unit, and branches and leaves may scratch the surface, thus reducing its performance.

9. Wide range of applications for solar power panels

Solar panels can be used in buildings, surveillance, road and bridge and even spacecraft and satellites. Even some portable solar charging panels can be used in cell phones, computers and other places.

10. Solar Panel Reliability

Photovoltaic systems are able to maintain power supply even under the harshest conditions. In contrast, conventional technologies are often unable to provide power when it matters most.
