"Sun? Are you talking about solar energy?" Liu Qingquan looked at the sun and filtered out the rays that were harmful to the human body through the thick protective glass. After the ultraviolet rays, the sun's light was not much different from that on the earth. It was still so bright and dazzling.

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

"The technology is indeed very simple, and the cost is not large, but to meet future needs, this area should be very large!" Liu Qingquan is not unfamiliar with solar power generation. You can often see space stations, satellites, etc. in other countries in the Space City, all with some wing-like things on it, these are solar power panels.

There are several types of solar power generation, one is crystalline silicon material, including single crystal silicon and polycrystalline silicon, and the other is amorphous silicon power generation, that is, it is not crystalline silicon, with thin-film solar energy and flexible solar power generation.

Crystalline silicon solar panels are basically useless in low-light environments, while amorphous silicon solar panels can still have a relatively good working condition in low-light.

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

Generally, what is the power generation per square day? Generally speaking, a crystalline silicon solar panel of 1 square is about 200-220W (technical progress is generally 120-140W now). If calculated based on 200W, 120W is equal to 0.2 kWh and equal to 0.2 kWh!

"The area requires a lot. Now the best single-crystal silicon solar power generation panel can generate 0.2 degrees of electricity in one hour. Of course, this is on the earth. If it is in space, because there is no weakening of the atmosphere, the sunlight intensity in space is 5-10 times that of the ground. Even if we count 5 times, a square single-crystal silicon solar power generation panel can generate 1 degree of electricity in one hour in space!"

"And in space we can generate electricity without gaps in 24 hours, and will not be affected by day and night like the ground. Solar power panels can use the best direct emission work at 24 hours a day, so the power generation efficiency is quite good!"

Jiang Zhipeng nodded and said the data he had already remembered. Solar power generation technology is not a new technology, but it is a new energy source, because solar power generation will not cause any pollution.

The idea of ​​using solar power to generate electricity in space has been proposed as early as the last century. In 2008, the Japanese even planned to invest 2 trillion yen to build a solar power station in space at a height of 36,000 kilometers above the ground. The power generation is expected to reach 1 billion kilowatt-hours!

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

"One square hour generates one kilometer of electricity, only 24 kilometers a day, and 8760 kilometers of electricity per year. According to the current use of 150 billion kilometers of electricity per year in Changan Space City, we need to build nearly 20 million square meters of solar power panels, and 20 million square meters is equal to 20 square kilometers!"

Liu Qingquan's hearing and his mind turned sharply, and he soon calculated the area needed to be built.

"It's almost 20 square kilometers, but for the sake of future considerations, we plan to build 100 square kilometers of solar power panels at one time, so that we can not worry about energy issues 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 current power consumption of Chang'an Space City, enough to meet the electricity demand of the future Phase 2 space factory and the Mars exploration spacecraft that will be started, and there is even excess energy to support the lunar base or earth base.

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

"It costs about $500 per square meter on the ground. The main cost is the battery, which accounts for nearly half. We have more advanced magnetic field batteries, which can save this. At the same time, because we are purchasing on a large scale, the price can still be negotiated, but we need to transport it from the earth to space and install it, so this cost is really hard to calculate at once!"

When talking about the cost, Jiang Zhipeng frowned, because this area is indeed not easy to calculate. The price of the ground is the price of the ground. The transportation of mineral water at 2 yuan per bottle of the ground is sky-high. Even if Qingquan Technology now has advanced space shuttles, the price of this transportation will not be too cheap.

Also, as Jiang Zhipeng said, Qingquan Technology is a large-scale centralized procurement this time, and the price can be reduced to a very low. Today's solar power generation equipment companies are very difficult to live due to the influence of Qingquan Technology's new energy tree. 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 company to survive and overcome difficulties, it is acceptable not to make money. Of course, Qingquan Technology has such a huge order, the cost can naturally be reduced when the quantity is large, and the profit can naturally be produced.

This price is subtracted and added, and it is not an easy task to calculate it!

"What is 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 future energy problems, Liu Qingquan probably has a number in his mind.

"The budget is 1 trillion US dollars, I think it should be enough!" Jiang Zhipeng told the project's planned budget.

"Is one trillion US dollars enough?" One trillion US dollars is nothing to Qingquan Technology. Qingquan Technology now monopolizes many industries around the world. Just monopolizing the global flying car market can allow Qingquan Technology to make more than 10 trillion US dollars in profits from the world every year. Now the company no longer pays attention to the earth's currency, and everyone is paying attention to internal contribution points now!

"Let's take a look first. If it's not enough, then add the budget. Anyway, the numbers in the Earth Bank will be a waste if you don't need them!" Jiang Zhipeng has become accustomed to the boss's generousness.

"Okay, you first polish the plan, cost and budget, and then take it to the board of directors to let everyone go through it!"

Liu Qingquan nodded and agreed to Jiang Zhipeng's plan. However, Qingquan Technology has now begun to slowly develop into a small country structure. Large projects involving a trillion dollars still need to be approved by the board of directors. Although Liu Qingquan also has this power, Liu Qingquan still has to respect everyone's opinions and at least they have to go through it.

"Yeah, OK!" (To be continued.)
