Chapter 4690

The utilization of solar energy is related to two key data: absorption rate and conversion rate. At present, the application of solar energy technology is relatively backward. Of course, it can not be said that it is backward. To be exact, it should be a very superficial application.

Solar energy absorption rate, the best technology at present, silicon solar panel is only 50%, and in the solar energy conversion rate, this is even worse. The solar energy conversion rate of monocrystalline silicon, the best solar panel, is only about 20%, while that of polycrystalline silicon is about 17%. The conversion rate of amorphous silicon solar panel is even lower, only about 10%.

Of course, this is a mass-produced solar electronic panel, not a mass-produced one. The conversion rate will be higher. However, this does not make any sense. For the sheikhs of the United Arab Emirates, they only focus on solar technology that can be used for civilian purposes.

According to the current solar technology, the best silicon solar panel has 45% solar energy absorption rate and 20% conversion rate, and the energy received by the earth per square meter per minute is about 1367w. If converted by this formula, the final energy converted by solar energy on the ground is 1367w multiplied by 45%, and then multiplied by 20%, What's the figure? 123.03w, 0.03W ignored.

That is to say, if you install a square meter of silicon solar panels in your home, it's about 1600 dollars. The energy you can get is 123 watts per minute and 7380 watts per hour, which is equivalent to 7.38 kilowatts of electricity.

According to the normal sunshine time of 8 hours a day, you can get 59.04 kilowatt hours of electricity a day. In terms of economic value, how much is it? According to the current electricity price in China, the current domestic electricity price is 0.52-0.62 yuan per hour. In other words, you can collect 30.7008 yuan to 36.6048 yuan of electricity from solar energy in one day. The two digits after the decimal point are ignored, which means that you can get 30.7 to 36.6 yuan of electricity charges.

If a family of three is equipped with a small solar generator set, it can meet the daily electricity demand of a family of three if it is guaranteed to have 8 hours of sunlight every day. Of course, in fact, if you want to install a solar power generating set, you need additional equipment, and its operation cost and maintenance difficulty are not cost-effective compared with the current household thermal power generation.

Of course, for these UAE chiefs, they don't think about it. What are they thinking about? Solar energy ban oil! That's what they're thinking about. What are the main uses of oil? It's very simple, as we all know, as fuel. Whether it's airplanes, cannons, cars or motorcycles, they all need oil as fuel.

With the depletion of oil, as well as the destruction of the ecological environment, more and more people begin to consider using a variety of clean energy to replace petroleum fuel. Solar technology is the most important factor affecting the wealth of the UAE chiefs.

At present, electric vehicles are under research and development. Although it's rechargeable, it doesn't seem to have much to do with solar energy. But don't forget, the car is driven outside. If the solar technology has made rapid progress, then the car roof can absorb solar energy solar panels, then whether it can guarantee the long-term driving of the car?

Under normal circumstances, due to the current poor solar technology, low absorption rate and conversion rate, all this has become extravagant. But now Lin Feng's solar technology is advancing by leaps and bounds.

80% absorption, which has nearly doubled. There's an even more terrifying conversion rate. At present, the best conversion rate for civilian use is 20%. Even for military use, it will not exceed 30%. On Lin Feng's side, the news they get is not optimistic. Spend a lot, a lot of money to get the news, let them very not optimistic. That's a conversion rate of at least 50%.

1367 watts of energy per minute, 80% absorption rate, plus 50% conversion rate, what's that? It's 546.8 watts per minute, nearly four times more than current technology. This number is quite terrible.

According to the calculation of 8 hours of solar radiation, one square meter of silicon solar panel can absorb 8 * 546.8 * 60 of energy in 8 hours, which is 262464 watts of energy, that is 262.64 kilowatts of electricity. If converted into money, it's 136.5-162.8 yuan.

Of course, the sheikhs of the United Arab Emirates don't care about civilian power generation. What they care about is, what if it's used in electric cars? At present, the main model of "DPCA" is electric vehicles. There are fewer and fewer fuel vehicles. The main model of "DPCA" is electric vehicles. Moreover, according to the information obtained by these chiefs, starting next year at the latest, DPCA will completely shut down all production lines of fuel vehicles and switch to full-scale production of electric vehicles. And the Chinese government may introduce a new policy to fully implement electric vehicles.

This is a very dangerous signal! As the world's most populous country, if electric vehicles are used all over the country, what will be the result? Oil prices will plummet. This will make life less comfortable for the Arab rich in Chengmen. Though, they are still rich. But it won't be like now, lying down can make money that other people can't make in their lifetime.

Of course, what about this solar electric car? The sheikhs of the United Arab Emirates have done a very detailed survey and spent millions of dollars to get a survey, a very terrible survey.

Electric vehicle, the most excellent electric vehicle technology of DPCA, has a power of about 155 kW. Of course, the power of the motor can be improved. This is not the focus. The focus is how much power is needed to drive a car with a deadweight of 2 tons for 100 km? This is the key. If solar energy is enough, it's terrible. With the previous solar technology, only 59 kilowatt hours a day can be converted. According to the data they got, it takes about 15 kilowatt hours for DPCA to be fully charged.

How far can you run at 15 degrees? It's about 50 kilometers. In other words, the existing solar panel technology, if the solar energy is abundant every day, can make the electric vehicle with a weight of 2 tons run 196.6 kilometers at room temperature.

However, this means that we can get 8 hours of abundant solar energy every day, and the car should always be exposed to the solar energy. But what is the global average sunshine time? The sheikhs of the United Arab Emirates once again conducted a survey. Taking Europe, America and Asia as examples, the average sunshine time is about four hours. This refers to the average annual sunshine time. An average exposure time that includes cloudy, rainy, snowy, midsummer and intense heat.

Four hours! It's the sunshine schedule of the world's most populous countries. According to the existing top-level civil solar energy technology, only 29.5 kilowatt hours of electricity can be absorbed in one day, and it can only run 98.3 kilometers when transmitted to the motor!

And it's a theoretical conversion rate. In fact, there is only 20% conversion rate for converting solar energy into electric energy at present. There is also a loss rate for transferring electric energy to motors and then to four-wheel drive vehicles. What is the loss rate from electric energy to kinetic energy?

At present, it is about 10%, that is to say, after the electric energy reaches kinetic energy, the loss rate is 90%. That's to say, you can run 88.47 kilometers with $1600 a square meter of silicon solar panels. Of course, there are other aspects of the loss, the emirate of the United Arab Emirates does not matter.

Because a car, parked in the sun every day, can guarantee to run 88.47 kilometers, once the long-distance words, simply can not support the long-distance use of the car. In this case, for petroleum fuel, the impact is not so big. At most, electric vehicles are just for short distance use in cities. Although electric vehicles, in addition to solar energy, can also use electric energy to charge cars. But once you have a long distance, in broad daylight, it can be as few as a few hundred kilometers and as long as thousands of kilometers. At this time, who will give you charging time?

Therefore, this old solar technology, for them, no harm. What's more, the 1600 dollar 1 square meter solar panel, installed in the car, is not so good-looking. Then, the impact is even smaller.

But Lin Feng's technology is amazing. After 4 hours of sunshine and the discount rate, it can still provide 118.188 kwh of electricity, which can make the car run 393.96 kilometers!

As long as 4 hours of sunshine, you can make the electric car run 393.96, close to 394 kilometers away! It's amazing. Basically speaking, it can meet the whole use time of about 4 hours. And this makes electric vehicles, from the urban use, into the use of short distance vehicles. This is a qualitative leap. More importantly, Lin Feng's solar technology has solved the bending problem of solar panels. At present, it can be bent and installed in accordance with the arc range of the car roof, which can ensure the beauty of the car appearance to the greatest extent. This is a breakthrough.

What's more, Lin Feng's solar technology is still in constant progress. At present, the absorption rate of solar energy is 80%, and the conversion rate is 50%. If the absorption rate reaches 90%, even the legendary 99.99...% as Lin Feng said, the conversion rate does not reach the same 99.99...%. As long as it reaches more than 70%, the electric vehicle with solar panels can be used as a long-distance bus.

As long as a pure electric vehicle, driving distance can be more than 600 kilometers, then it can become a means of transportation between cities. And because of its environmental protection, energy saving and other advantages, it will become people's first choice.

Think about it. If you buy a car, under normal use, you can hardly provide any energy, and the car can always meet your daily needs, and it is fashionable, beautiful and environmentally friendly. Will you buy it?

What's more, according to the intelligence of the UAE chiefs, the starting price of such a two ton, 155 kW solar electric vehicle in China is about 130000 yuan. This price is super cheap. Of course, this is the most basic model. There are more luxurious SUVs with larger batteries, and other models, which are not expensive. The most expensive is only about 500000 yuan.

Such competitiveness is very strong. Even in the United States, where the oil price is the cheapest, most American families would like to have such solar cars. If so, then, once the solar car is popular, the future will be very terrible.

Then the price of oil will plummet. However, in the field of aviation, oil is still irreplaceable. But if the biggest demand for oil for civilian cars, no longer need oil, then oil prices will be so high? Moreover, it must be noted that Lin Feng's solar energy technology may not be able to be used in the aviation field. After all, the area on the plane where solar panels can be installed can be larger, and the plane can get more solar energy when it flies 10000 meters above the clouds.

When they think about it this way, they feel terrible.

So this time, in the name of "Huangdi wine" and "air water wheel", they all gathered together to talk about the solar energy technology with Lin Feng.

"What do you mean, gentlemen?" Lin Feng asked.

Many chiefs, you look at me, I look at you. Finally, Emir Tamim bin Hamad al Thani, who has a good relationship with Lin Feng, stood up.

"Mr. Lin, we think that solar energy technology is really changing the world economy, but it may not be mature at present. And we hope Mr. Lin can make the solar energy utilization rate and conversion rate reach more than 90%, and push it out after the cost is reduced. " Chief alsani said in a deep voice.

Lin Feng frowned. This request, however, is quite unreasonable.

"Of course, we will make up for it. The annual compensation is 100 billion US dollars. We, the chiefs, give Mr. Lin 100 billion US dollars of free research funds every year as compensation for the postponement of the launch of this program! " Chief al Thani looked at Lin Feng and said nothing.

All the chiefs are looking at Lin Feng. This is their response to solar technology. 100 billion dollars to buy the delayed launch of this technology.
