"The sun? You mean solar? Liu Qingquan's eyes looked at the sun, and after filtering out the rays and ultraviolet rays that are harmful to the human body through the thick protective glass, the sun's rays were not much different from the earth in his eyes, and they were still so bright and dazzling.

"Well, that's right, the technology of using solar power is relatively simple, the construction cost is not large, and the operation is even simpler, you only need to erect a huge solar panel in space!" Jiang Zhipeng nodded.

"The technology is really simple and the cost is not huge, but to meet the needs of the future, this area should need to be very large!" Liu Qingquan is no stranger to solar power generation, and you can often see other countries' space stations, satellites, etc., all with some wing-like things, which are solar power panels.

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

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

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

How much does a square meter generate electricity in a day? Generally speaking, 1 square crystalline silicon solar panel is about 200-220W (technological progress, now it is generally 120-140W), if calculated according to 200W, 120W is equal to 0.2 kWh, equal to 0.2 kWh!

"Area is needed a lot, now the best monocrystalline silicon solar panels can generate 0.2 degrees of electricity an 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 5-10 times that of the ground, even if we are 5 times, a square of monocrystalline silicon solar panels in space can generate 1 kilowatt-hour of electricity!"

"And in space, we can generate electricity 24 hours a day, and will not be affected by day and night like the ground, and solar panels can work 24 hours a day with the best direct light, and this power generation efficiency is still quite good!"

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 new energy, because solar power generation will not produce any pollution.

In 2008, the Japanese planned to invest 2 trillion yen to build a solar power plant in space at an altitude of 36,000 kilometers above the ground, and the power generation capacity is expected to reach 1 billion kilowatt hours!

There is no atmosphere in the sun to weaken the light, and it can work at its best 24 hours a day, so solar power generation is still quite attractive.

"1 square hour of electricity generation 1 degree, a day is 24 degrees, a year is 8760 degrees of electricity, according to the current Chang'an Space City 150 billion kilowatt-hours of electricity a year, we need to build nearly 20 million square meters of solar panels, 20 million square meters is equal to 20 square kilometers!"

Liu Qingquan's hearing head turned sharply, and he quickly calculated the area that needed to be built.

"It's almost 20 square kilometers, but we plan to build 100 square kilometers of solar panels at a time for the future, so that we don't have to worry about energy problems for a long time in the future!"

Jiang Zhipeng said the plan, an area of 100 square kilometers, according to calculations, is enough to produce five times the current electricity consumption of Chang'an Space City, enough for the future phase II of the space factory and the upcoming construction of the Mars exploration spacecraft, and even has excess energy to support the moon base or earth base.

"It's a lot of money, how much is the estimated cost?" Liu Qingquan smiled, Jiang Zhipeng's solar power generation plan is still quite feasible, as he said that there is no technical content, and it is very simple and practical, and now we need to pay attention to its cost.

"About 500 US dollars per square meter on the ground, the most important cost is the battery, accounting for nearly half, we have more advanced magnetic field batteries, this can be saved, and because we are large-scale procurement, the price can still be negotiated, but we need to be transported from the earth to space, and we also need to install, so this cost is really not easy to calculate!"

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

There is also as Jiang Zhipeng said, Qingquan Technology this time is a large-scale centralized procurement, the price can be pressed to a very low, now solar power generation equipment enterprises because of the impact of Qingquan Technology's new energy tree, life is very difficult, Qingquan Technology's orders, I believe that even if you don't make money, you are willing to do it.

As long as you can find enough orders for the enterprise, so that the enterprise can survive and survive the difficulties, it is acceptable not to make money.

This price is subtracted and subtracted, and at the same time added and added, it is really not a simple thing to calculate!

"What's the budget?" Since the price is not easy to calculate, Liu Qingquan asked about the budget again, this can be controlled, and for projects that can solve future energy problems, Liu Qingquan probably already has a number in his heart.

"The budget is $1 trillion, which I think is almost enough!" Jiang Zhipeng said the planned budget of the project.

"Is a trillion dollars enough?" One trillion dollars is nothing for the current Qingquan Technology, Qingquan Technology now monopolizes many industries around the world, and the monopoly of the global flying car market alone can make Qingquan Technology earn more than 10 trillion US dollars in profits from the world every year.

"Let's take a look first, let's add to the budget if it's not enough, anyway, it's a waste if you don't have to use the numbers in the Earth Bank!" Jiang Zhipeng is used to the generosity of the boss.

"Okay, you first polish the plan, make the cost and budget more detailed, and then put it forward to the board of directors for everyone to go through!"

Liu Qingquan nodded and agreed with Jiang Zhipeng's plan, but now Qingquan Technology has begun to slowly develop into a small country structure, and such a large project involving a trillion US dollars still needs to be approved by the board of directors.

"Yes, okay!" (To be continued.) )
