A few decades ago, our technology was not so advanced, so the exploitation and use of natural resources can be described as unrestrained, which has also led to the depletion of some resources.
The so-called science and technology can change the times, with the continuous research and development of technology, now our life is more and more advanced, all kinds of electrical appliances not only into thousands of households, but also the global energy structure has been fully adjusted.
Nowadays, there are many renewable energy sources in our lives, such as wind energy and solar energy, which are fully utilized, wind power, solar lighting, etc., have brought a lot of convenience to our lives.
In the past two years, the mainland has made good achievements in the field of new energy, which has promoted the mainland to stand in the leading position in the world in this regard, and the photovoltaic power generation industry has gradually become the mainstream in the field of new energy.
The mainland has a relatively strong voice in this regard, and the technology is ahead of many Western countries, but some people have raised questions about this, is it really good that the mountains are full of photovoltaic panels?
First, the advantages of photovoltaic panels
With the increasing global demand for renewable energy, photovoltaic power generation has become a clean and efficient energy model, and it is being widely used in various fields.
We have always said that man and nature should live in harmony, but as the natural environment continues to change, we have also found that there are many natural forces that we cannot contend with.
In order to achieve sustainable development, scientists have begun to conduct continuous research to make the best use of all kinds of natural resources.
At this time, everyone found that wind and solar energy in nature are endless, unlike those coal resources, which require hundreds of years or thousands of geological evolution to form.
As a result, wind power generation equipment has appeared in many regions, and large-scale power stations have been established in many areas, and wind power generation is very efficient and meets the most basic needs of life in the city.
With the continuous improvement of technology, the mainland's power generation equipment is becoming more and more comprehensive, and photovoltaic panels have come into being, which are devices that convert solar energy into electrical energy.
In other words, as long as the photovoltaic panel is placed outdoors and exposed to sunlight, it can generate electricity, and in the process it does not require any fuel at all, and does not produce harmful carbon dioxide gases.
This not only converts natural resources into renewable energy that can be used by us, but also achieves an environmental effect, without the need for media and unnecessary waste in the process.
Nowadays, some mobile phones and various electrical appliances used by outdoor personnel will be equipped with small photovoltaic panels, which can help them achieve sufficient power in the field environment.
At this time, some people may point out that the production and manufacturing of photovoltaic panels requires a lot of costs, but its service life is particularly long, ordinary photovoltaic panels can be more than 25 years, and its later maintenance costs are particularly low.
In the past, when photovoltaic panels were first launched, many regions encouraged people to install them, and installers could use photovoltaic panels to provide long-term power support for homes or businesses.
The surplus electricity generated can also be sold to local power supply companies, which can then use the electricity collected from retail customers to use it in the industrial field or sell it directly to other countries to increase fiscal revenue.
At that time, many people made a lot of money from this project, and the sun would rise every day, which meant that you didn't have to do anything after installing photovoltaic panels, and you had a fixed income every day.
Photovoltaic panels do not have much requirements for the installation environment, you can install them on the roof, you can install them in the yard, and even install them in the field, and it is precisely because of this that it can provide corresponding convenience to different places.
Second, the disadvantages of photovoltaic panels
But we also know that everything must have drawbacks, the advantages of photovoltaic panels are obvious, and they have been widely recognized by everyone, but it also has disadvantages in the process of use.
This device is particularly demanding on sunlight, and if you are in an area with constant rainy days all year round, it may lead to a lack of sunlight, or if you install it at the wrong angle, the power production of the photovoltaic panels will be greatly reduced.
After installing photovoltaic panels, some people originally wanted to make a profit, but in the end they found that after spending tens of thousands of yuan in installation fees, the final electricity generated was only enough for the daily use of the family.
It is likely that because you install it at the wrong angle, the power production environment of the photovoltaic panels will be affected by the local climate, which must be considered before installation.
Photovoltaic panels convert solar energy into electricity, mainly relying on various equipment inside, of which silicon wafers are the main and most core components.
In the process of use, photovoltaic panels consume a particularly large amount of energy, especially silicon wafers, which require a large amount of electrical energy and material resources, which may lead to high environmental costs for photovoltaic panel production.
But we also know that there will be high harvest with high investment, and the first group of people to install photovoltaic panels did make money, and there are many farmers who can earn five or six thousand a month by relying on photovoltaic panels, which greatly increases family income and improves the economic conditions of the masses.
Installing photovoltaic panels definitely costs money, most of them range from tens of thousands of yuan, if you can earn 5,000 a month, the installation cost can be paid back in more than a year, and it will be profitable for you for more than 20 years.
Of course, we also have to make decisions based on our own financial situation when installing, and we should be cautious if we install this facility, which may cause huge debts to the family.
3. The impact of photovoltaic panels on the future
Now is undoubtedly an era of science and technology, any field is developing in the direction of high efficiency and energy saving, so even if photovoltaic panels have shortcomings, they have also been widely recognized by the society.
From the perspective of environmental protection, it is a relatively environmentally friendly form of energy, which can effectively reduce carbon emissions and environmental pollution, and provide energy security for everyone.
With the continuous mining, environmental protection problems are becoming more and more serious, photovoltaic panels are a product of this era, and may be used in more fields in the future.
If you consider it from an economic perspective, there may be a relatively high investment in the early stage, but with the continuous maturity of technology, its price is also decreasing, and his future prospects are very good, and the possibility of profitability is very high.
Now there are many business tycoons who have taken a fancy to this field and made high investments, which can also be seen that this is a sunrise industry.
Just like the new energy vehicles in the current era, after playing the slogan of zero emissions, they quickly seized the market share, and now there is a trend to replace fuel vehicles.
Photovoltaic panels can make full use of natural resources, further realize the expectation of harmonious coexistence between man and nature, and once there is an energy crisis one day in the future, photovoltaic panels will definitely come in handy.
Fourth, the mountain of photovoltaic panel cells
Now we have gradually accepted the mode of photovoltaic panel power generation, and many areas have begun to be officially applied, in the Taihang Mountains of Handan, Hebei Province, the whole has been laid with photovoltaic panels, the scene is very spectacular.
From the pictures taken by netizens using drones, we can see that the entire Taihang Mountains are undulating, and after laying photovoltaic panels, they emit sparkling light under the sun, just like a giant dragon.
Photovoltaic panels have been installed in many nearby mountain ranges, which is reported to be poverty alleviation by the local photovoltaic industry, which can effectively solve the electricity problem of the local people.
The Taihang Mountains have beautiful scenery, and now they are wearing a layer of armor, just like a general guarding a piece of land, and solving the energy problem for the people.
The installation of this electric power generation equipment has been supported by the local people, and it has also been likened to planting the sun, which has made people's lives look new.
The mountains in the vicinity are difficult to grow crops, and the economy is slow due to the rugged roads, which is why the state has installed photovoltaic panels on the slopes of these impoverished areas.
These hills are also idle, usually overgrown with weeds, it does not have much use value, it is better to press it on photovoltaic panels, can bring economic benefits to the local government and enterprises.
According to the data, after the area is covered with photovoltaic panels, it can provide an average of about 240 million kilowatt hours of green energy to the local area every year, saving 84,000 tons of standard carbon and reducing carbon dioxide emissions by 239,000 tons per year.
Some people were shocked to see this scene, and felt that this was the best portrayal of technology changing life, but some people questioned it.
Some netizens said that the scenery was destroyed, and although the photovoltaic panels were laid, they could absorb solar energy and convert it into electricity to meet everyone's living needs, reflecting the current level of science and technology.
But for Dashan, so many photovoltaic panels are like a big plaster sticking to his body, and he can't get rid of it, which causes the vegetation on the mountain to grow normally, and it will definitely change the ecological environment over time.
This netizen's concern is also reasonable, but the advantages of laying photovoltaic panels on barren mountains outweigh the disadvantages, and the country's decision will definitely be based on the interests of more people.
In fact, this thing is the same as breathing air, everyone's life depends on air, and carbon dioxide is also produced between breathing and breathing, and if you breathe less, it is good for others.
summary
In some remote areas, the state will give more scientific and technological and economic assistance, which is to improve the local economic outlook and allow more people to enjoy the benefits of science and technology.
Photovoltaic panels are laid in a large area on the Taihang Mountains, which not only generates electricity to ensure everyone's energy needs, but also effectively cools the local area, because photovoltaic panels can absorb heat, which can be described as killing multiple birds with one stone.
We need to look at this matter from a scientific perspective, in areas where the environment is harsh or there is no grass, or where precipitation is low, photovoltaic panels are an effective way to improve the environment, which can block some sun exposure and also play a certain role in local soil erosion.
