Chapter 1038 China's First Photovoltaic Power Station

Qin Tianshan frowned, with worry in his tone: "Xiaoqing, don't lie to me, I know that photovoltaics is a clean energy, and I have been thinking about this recently.

Photovoltaic power generation has limited conversion efficiency, and photovoltaic panels occupy a large area, so there are too few scenarios where it can be used on a large scale!

The places where photovoltaic power generation can be arranged now are all sparsely populated areas.

You have generated electricity, but how do you use it? How do you transmit it? These are all problems!

If power is abandoned in the future, it will be a waste of resources!"

Qing Yun patiently explained: "Second Uncle, what you mentioned is indeed the challenge that photovoltaic power generation is currently facing.

However, have you ever thought that with the advancement of technology, the conversion efficiency of photovoltaic panels is constantly improving and the cost is decreasing year by year.

More importantly, photovoltaic power generation can actually be very flexible, and Uncle Er..."

He was too lazy to talk about distributed power generation, and pulled Qin Tianshan out. "Don't worry, uncle. Come with me to a place. I will let you see the true potential of photovoltaic power generation."

As he spoke, he gestured to Sister Xiaoya and Yang Bingnan to go and notify the convoy.

Everything you say is just empty talk, seeing it with your own eyes is believing!
Coincidentally, there is a place in Lanzhou that can provide cases, and it is not far from here.

After all, Jincheng is a provincial capital, and the Yanhuang Group has subsidiaries here. The vehicles and other things have been arranged long ago, and they don’t use all of Dongfang Houpu’s cars.

……

A small convoy consisting of several black cars was speeding on the Dingxi to Jincheng section of the Qinglan Expressway which had just opened to traffic, following Qing Yun's instructions.

Qin Tianshan sat in the car and did not ask Qingyun where he was going. Instead, he chose to close his eyes and rest.

In fact, he already believed it a little bit in his heart.

Not for others.

Just because Qing Yun knew the situation in Jincheng so well, he realized that this brat had a very deep mind.

This means that Qingyun has truly conducted in-depth research on this industry and even the development of this industry in Jincheng.

The convoy got off the highway and finally stopped on an inconspicuous road.

After Qin Tianshan got off the bus, he looked around. This place was obviously far away from the hustle and bustle of the city, but he still couldn't help asking, where is this?
He remembered that the convoy had just passed by the only 985 university in Longyou - Jincheng University. How come they came to such a remote place in the blink of an eye?

Qing Yun smiled and said mysteriously, "Uncle, we need to go up the mountain. It's not far. We can get there in about ten minutes on foot."

Although Qin Tianshan was curious, he did not ask much and walked away with his hands behind his back.

Xiao Ya followed the team, her heart full of doubts.

How did the little kid find such a remote place?
Soon, the group arrived at the hillside and saw a stone sign from afar - Longyou Natural Energy Research Institute Asia-Pacific Solar Energy Research Institute.

The name on the sign sounds grand, but the scale of the institute seems a bit shabby, with only two three-story buildings.

However, when Qin Tianshan saw the photovoltaic panels on the roof sparkling in the sun, he was stunned.

Qing Yun said calmly: "The photovoltaic power station in Yuanzicha Township, Yuzhong County, Jincheng, Longyou, is the first photovoltaic power station in our country. It was built in 1983."

"1983?" Qin Tianshan took a breath. He didn't expect that photovoltaic power generation has such a long history in China.

Qing Yun nodded with a smile and continued to explain, "He is older than me and it has been 20 years now.

The installed capacity is 10 kilowatts. Due to the imperfect infrastructure in that era, the village we just visited had no electricity.

The Natural Energy Research Institute used the solar cells and a set of photovoltaic panels donated by Sakura to build a photovoltaic power station for them.

10 kilowatts is not a lot, but it is enough for each of the 36 households in the village to use two fluorescent lamps.

In the 90s, electricity from the national grid was delivered to the village below, and the photovoltaic power station was abandoned.

The Natural Energy Research Institute moved the power station inside the institute for internal use.

The power station is still generating electricity and was connected to the grid last year.”

Qing Yun was talking on the phone at the same time, and soon the door of the Natural Science Institute opened.

Several staff members appeared at the door to greet them.

Qing Yun explained to Qin Tianshan in a low voice: "I asked my teacher to arrange it."

After that, he walked up to the leading staff and started chatting: "Hello, Mr. Lan."

The staff member is called Lan Fanfan, the chief engineer of the Natural Energy Research Institute. After receiving a call from Chen Yiquan, he rushed over from the laboratory of Jincheng University.

He warmly welcomed Qing Yun and his party and took them to visit this historic photovoltaic power station.

Lan Fanfan led a group of people into the exhibition hall of the institute. The old photos hanging on the wall recorded the history of the establishment and use of this photovoltaic power station. He pointed to one of the photos and began to introduce: "This photovoltaic power station was built in 1983. It is the first photovoltaic power station in my country. At that time, it was built to solve the problem of no electricity available here."

There was a hint of pride in his voice: "At that time, photovoltaic technology was just starting out internationally, and it was not easy for our country to take the first step in this field.

The original installed capacity of this power station was 10 kilowatts. Although it seems small now, at that time, it helped the residents of Yuanzicha Township say goodbye to kerosene lamps. "

“…After the relocation, due to the loss of some parts, the installed capacity of the entire power station is now 7 kilowatts, but it is enough for our institute’s office use.

Early photovoltaic panel technology was immature, the conversion efficiency was relatively low, and the materials were not as durable as they are today.

However, they can still operate stably in harsh environments, which proves the reliability of photovoltaic power generation."

Lan Fanfan introduced to them the operation and maintenance of the entire photovoltaic power station.

Under Lan Fanfan's introduction, Qin Tianshan carefully observed every detail of the power station, from the arrangement of photovoltaic panels to the operation of inverters, and to the storage and transmission of electricity.

Looking around, I saw that the computers, printers and other equipment in the institute's office were operating normally. It was obvious that the electricity provided by this power station was stable and reliable.

Lan Fanfan took them to visit the control room of the power station and pointed to a running inverter and said,

“This inverter was replaced later. It can convert the direct current generated by the photovoltaic panels into alternating current for our use.

Moreover, it has an automatic adjustment function, which can adjust the output power according to the changes in light intensity to ensure a stable supply of electricity.”

Qin Tianshan's eyes gradually revealed recognition and appreciation, and he began to understand why Qing Yun was so confident in photovoltaic power generation.

Damn, in 20 years, the photovoltaic power generation efficiency of the entire power station has only dropped by 13% compared with the design value.

In other words, the original belief that photovoltaic modules have a lifespan of 25 years is a serious underestimate.

Doing business is all about accounting, let alone Qin Tianshan, the godfather of business who is famous for his cost control.

His eyes lit up instantly.

Seeing that he understood, Emperor Yun curled up his lips into a smile.

More than 25 years...

After another 20 years, when the power station is 40 years old, the overall efficiency value will only decrease by 21%.

This is because the villagers did not properly maintain the power station and even used it as a pigpen door during the first few years after the power station was abandoned.

According to Yundi’s own calculations, the efficiency attenuation value of the entire photovoltaic module should not exceed 40% in 16 years.

The life of the entire solar panel actually depends entirely on the life of its accessories, tempered glass, TPT (polyethylene terephthalate)/PEVA (polyethylene vinyl acetate), rather than on the polycrystalline silicon or monocrystalline silicon itself.

In other words, all the economic modeling based on a 25-year design life was wrong.

The enormous value and low cost of photovoltaics are something that people at this time are simply not aware of.

This has led to a serious overestimation of the cost of photovoltaic power generation.

如果修改经济测算模型按照运维40年计算，2023年光伏度电成本仅0.07元，光照充足区域最低可达0.04元，远低于水电的0.25元和风电的0.2元。

Qing Yun is very clear that with the implementation of the Green Mountains and Clear Waters Strategy, his investment, which he had made early arrangements for, will be richly rewarded.

Qin Tianshan stood in front of this micro photovoltaic power station that has been in operation for 20 years and was amazed.

His eyes wandered over the photovoltaic panels that still sparkled in the sun, full of respect for the durability and reliability of this technology.

Lan Fanfan stood aside with a smile, answering Qin Tianshan and Qing Yun's questions from time to time.

He knew very well that the two people in front of him were potential big money sponsors.

He kept touting the superiority of photovoltaic power generation, not because he had any personal interest in it, but because this was what he was researching, and naturally he hoped that the industry would be more prosperous, and perhaps there would be opportunities for cooperation.

There must be one.

After all, in this area of ​​Jincheng, a large construction site covering thousands of acres suddenly appeared, which was hard not to attract attention.

The local news could not be concealed. Everyone knew that the construction site was the joint factory of Dongfang Houpu and Yanhuang Group.

The total investment is at least tens of billions of yuan, and it should be considered Jincheng’s largest investment promotion project this year.

It’s just that it hasn’t been officially announced yet.

After all, according to local practice, in addition to the signing ceremony, a grand groundbreaking ceremony is also required.
