The sun? You mean solar energy? Liu Qingquan looked at the sun. After filtering out the rays and ultraviolet rays that were harmful to the human body through the thick protective glass, the light of the sun reached his eyes and did not have much light on the earth. The difference is still as bright and dazzling.

Well, yes, the technology of using solar power to generate electricity is relatively simple, the construction cost is not large, and the operation is even simpler. You only need to set up a huge solar panel in space! Jiang Zhipeng nodded. .

The technology is really simple and the cost is not too big, but to meet future needs, this area should be very large! Liu Qingquan is no stranger to solar power generation, and space stations of other countries can often be seen in Space City. , satellites, etc., all with some wing-like things on them, these are solar panels.

There are several kinds of solar power generation, one is crystalline silicon material, there are two kinds of monocrystalline silicon and polycrystalline silicon, the other is amorphous silicon power generation, that is, not crystalline silicon, there are thin film solar power, flexible solar power generation.

Crystalline silicon solar panels are basically useless in low light environments, while amorphous silicon solar panels can still work well in low light.

However, the conversion rate of amorphous is low, and crystalline silicon solar power is more widely used now.

What is the average power generation per square meter per day? Generally speaking, 1 square crystalline silicon solar panel is about 200-220W (technical progress, now it is generally 120-140W), if it is calculated by 200W, 120W is equal to 0.2 kWh, which is equal to 0.2 kWh!

The area needs a lot. Now the most hǎode monocrystalline silicon solar panels can generate 0.2 degrees of electricity per hour. Of course, this is on the earth. If it is in space, because there is no weakening of the atmosphere, the intensity of sunlight in space is the same as that of the ground. 5-10 times, we can even consider 5 times, a square monocrystalline silicon solar panel can generate 1 kWh of electricity in one hour in space!

And in space, we can generate electricity 24 hours a day without a gap, and it will not be affected by day and night like the ground. The solar power generation panel can work 24 hours with the most direct sunlight, and the power generation efficiency is quite acceptable!

Jiang Zhipeng nodded and said the data he had memorized for a long time. Solar power generation technology is not a new technology, but it is a kind of new energy, because solar power generation does not produce any pollution.

The idea of ​​using solar power in space has been proposed as early as the last century. The Japanese even planned to invest 2 trillion yen in 2008 to build in space at an altitude of 36,000 kilometers from the ground. A solar power station is expected to generate 1 billion kWh!

There is no atmosphere in the sun to weaken the light, and it can be in the best working condition 24 hours a day, so solar power generation is quite attractive.

One square meter generates 1 degree of electricity per hour, 24 degrees per day, and 8,760 kilowatt-hours in one year. According to the current annual consumption of 150 billion kilowatt-hours of electricity in Chang'an Space City, we need to build nearly 20 million square meters of solar power generation. The board will do, 20 million square meters is equal to 20 square kilometers!

Liu Qingquan's head turned sharply, and he quickly calculated the area to be constructed.

It's almost 20 square kilometers, but for future consideration, we plan to build 100 square kilometers of solar panels at one time.

In this way, we will not have to worry about energy problems for a long time in the future!

Jiang Zhipeng explained the plan. According to calculations, the area of ​​100 square kilometers is enough to produce 5 times the electricity consumption of Chang'an Space City, enough for the future Phase 2 space factory and the upcoming Mars exploration spacecraft. Electricity demand, and even excess energy can be supported to the moon base or the earth base.

It's quite big, how much is the estimated cost? Liu Qingquan smiled. Jiang Zhipeng's solar power generation plan is still quite feasible. As he said, it has no technical content and is very simple and practical. Now what needs to be paid attention to is its cost.

A square meter on the ground costs about 500 US dollars. The main cost is the battery, which accounts for nearly half. We have a more advanced magnetic field battery, which can be saved. At the same time, because we are large-scale purchases , the price can still be negotiated, but we need to transport it from the earth to space, and also need to install it, so this cost is really hard to calculate all of a sudden!

When it comes to the cost, Jiang Zhipeng frowned, because this piece is really not easy to calculate, the price on the ground is the price on the ground, and the 2 yuan bottle of mineral water on the ground is too expensive to transport into space. Even if Qingquan Technology now has an advanced space shuttle, the price of this transportation will not be too cheap.

In addition, as Jiang Zhipeng said, Qingquan Technology is a large-scale centralized procurement this time, and the price can be kept very low. The current solar power equipment companies are affected by Qingquan Technology's new energy tree. It's not easy, Qingquan Technology's orders are believed to be willing to do even if they don't make money.

As long as it can find enough orders for the enterprise, it is acceptable for the enterprise to survive, overcome the difficulties, and not make money. Of course, with such a large order of Qingquan Technology, the cost can naturally be reduced if the volume is large, and the profit will naturally come out.

This price is subtracted, subtracted, and added at the same time. It is really not an easy thing to calculate!

What's the budget? Since the price is not easy to calculate, Liu Qingquan asked about the budget again. This is controllable. For projects that can solve the future energy problem, Liu Qingquan probably already has a number in mind.

The budget is 1 trillion US dollars, I think it should be enough! Jiang Zhipeng said the planned budget of the project.

Is one trillion US dollars enough? One trillion US dollars is nothing to the current Qingquan Technology. Qingquan Technology now monopolizes many industries in the world. Simply monopolizing the global flying car market can make Qingquan Technology go from The world has earned more than 10 trillion US dollars in profits. Now the company has not paid attention to the earth currency. What everyone now pays attention to is the internal contribution point!

Let's take a look first, if it's not enough, then add more budget. Anyway, the numbers in the Earth Bank are not wasteful! Jiang Zhipeng was used to the boss's generosity.

That's it, you first polish the plan, make some details about the cost and budget, and then bring it up to the board of directors for everyone to have a look at!

Liu Qingquan nodded and agreed with Jiang Zhipeng's plan, but now Qingquan Technology has begun to slowly develop into a small country structure. Such a large project involving one trillion US dollars still needs to be approved by the board of directors. Although Liu Qingquan also has this power , but Liu Qingquan still has to respect everyone's opinions, or at least ask everyone to have a good time.

Well, hǎode! (To be continued.)
