Super Orchard

Chapter 75 Photovoltaic Power Generation
The sun rose slowly, bringing warmth to Jinquan Village after the autumn rain. The crowd of onlookers at Wang Chunmei's house slowly dispersed, and Shen Yangguang returned to the orchard again.

During this period of time, the weather was getting colder, and the lowest temperature at night was close to zero. Shen Yangguang suddenly remembered the heavy snowfall last autumn, and the snow removal system built in the greenhouse could not work due to power problems.

Seeing that the first snow of this year is coming soon, Shen Yangguang began to think about laying photovoltaic power generation panels to provide sufficient power for lighting and heating equipment in the orchard.

There is no need to search for a manufacturer of photovoltaic power generation panels. The company that installed the street lights just happened to have this kind of equipment. Shen Yangguang called Zhao Ming, the boss of their company, and a group of people came to the scene the next day.

After using the solar street lights in the orchard for a period of time, not only did Zhao Ming work well, but there were no problems, so Shen Yangguang was very relieved of Zhao Ming's company.

Shen Yangguang stood waiting at the gate of the orchard, and a commercial vehicle with a provincial license plate also stopped at the gate. After Zhao Ming got out of the car and shook hands with Shen Yangguang enthusiastically, the two talked about specific construction matters while walking.

Shen Yangguang pointed to the road in the orchard and said: "I want to erect photovoltaic power generation panels on this road, Mr. Zhao, do you think there is any problem?"

Setting up photovoltaic power generation panels above the road is an idea that Shen Yang had long ago. This can not only improve the efficiency of land use, but also help the road surface to block rain and snow in winter and prevent the road surface from being slippery.

In summer, it can also shade the road surface, so that people walking on it do not have to endure the sun exposure, which can be said to serve multiple purposes.

Zhao Ming nodded and said, "That's no problem at all. You just need to bury supports on both sides of the road, build a solid roof over it, and put photovoltaic power generation panels on it."

The conversation turned and he continued: "Mr. Shen, your idea is very good. The power generation panels and roads can use the space three-dimensionally, directly doubling the utilization rate of the land, but..."

"But what?" Shen Yangguang thought there was some flaw in this idea, so he hurriedly asked.

"But if you do this, the street lights laid before will be wasted."

What is the relationship between street lights and photovoltaic panels?Shen Yangguang was puzzled and asked, "How do you say that?"

"Think about it, after this kind of photovoltaic power generation equipment is assumed, there are brackets on both sides that can be used as light poles, the photovoltaic power generation panels on the top can directly generate electricity, and there are batteries and so on. The lamp head and controller can be used as a street lamp, where is it necessary to build a special street lamp?"

Knowing that it cost a full 100 million yuan to erect these street lights, Shen Yangguang was a little annoyed and said, "Mr. Zhao, why didn't you say so earlier!"

Zhao Ming said helplessly: "At that time, you just said that you wanted to lay photovoltaic power generation panels. I thought you were planning to find an open space. Who knew it was going to be erected on the road. If I knew your idea at that time, I would definitely I will advise you."

Think about it, let alone Shen Yangguang, an outsider, even Zhao Ming has been in this industry for so many years, and he has never heard of any place where photovoltaic power generation panels are erected above the road.

It is not impossible to do this, but almost all places where photovoltaic power generation panels are laid have enough open space, and there is no need to share a piece of land with the road, not to mention that the cost of the support will increase if the photovoltaic power generation panels are erected several meters high A lot, people have a lot of open space, why bother and spend more money?
Shen Yangguang sighed, and said with a wry smile: "That's how it is, the street lamps are all set up, so they can't be taken down again, right?"

Zhao Ming quickly glanced at both sides of the road and said: "It's not impossible to dismantle it. I have an idea. I don't know if Mr. Shen is willing to listen to it?"

"What attention?"

"The road in the orchard is two kilometers long. There should be no need to lay photovoltaic power generation panels with such a large area, right? I want to remove the street lights on the road where the power generation panels are laid and hang them directly on the brackets under the power generation panels. Lamp holders and controllers, these dismantled street lamps must not be many, your orchard is so big, you can continue to use it wherever you want.”

Shen Yangguang thought it made sense, and Zhao Ming went on to say: "There are no complicated cables at the bottom of the solar street light, and it is very simple to move there. It is just a matter of digging a hole and filling it. You can continue to keep the street lamps to provide lighting. Of course, if you want to add photovoltaic power generation panels in the future, you can continue to move the street lamps. Anyway, the orchard is so big, these street lamps will not be wasted.”

Shen Yangguang thought about it carefully, and found that Zhao Ming was really business-minded. If he followed what he said, not to mention solar street lamps and photovoltaic power generation panels, the other party could sell him a large number of lamp holders and controllers.

However, what Zhao Ming said is also very reasonable. In the short term, this will increase the cost by one ratio, but in the long run, it can save a lot of money. You must know that only installing the lamp head and controller is more expensive than installing street lights. Save a lot of money.

Besides, as the orchard expands, there will be more and more greenhouses in the future. In addition to this main road, there are some auxiliary roads at the entrance of the greenhouse that need to install more solar street lights, so these street lights are not at all. will be wasted.

After adopting Zhao Ming's opinion, the two continued to discuss the size of photovoltaic power generation panels to be laid.

Currently there are only three greenhouses in the orchard. Under the leadership of Shen Yangguang, Zhao Ming recorded the power consumption of each greenhouse, took out a calculator and began to calculate.

Shen Yangguang also introduced the specific amount of electricity used in the greenhouse.

"The electricity consumption of the first greenhouse and the second greenhouse is slightly higher in winter, which is mainly determined by the characteristics of tropical fruit trees for picking strawberries and mango trees in winter."

"However, it doesn't need too much. We only need to provide some lighting at ordinary times. Only when the winter is the coldest, we need to turn on the second level of warm air in the evening to increase the temperature. In addition, when it snows, we will turn on the third level to melt and remove snow. .”

"If the weather is abnormally cold and the temperature drops suddenly, the opening time of the second gear will be extended, and the third gear will also be opened from time to time to rapidly increase the temperature."

"The third greenhouse grower is Bufona. It doesn't have high temperature requirements. It only needs ordinary lighting. It is enough to turn on the second gear to increase the temperature in the coldest time. By the way, there are also rainy and snowy days. Snow removal will be done as well.”

Zhao Ming calculated the average energy consumption based on the different powers of the first gear, second gear and third gear in the greenhouse, combined with the approximate use time of each gear, and calculated for a long time based on the power generation efficiency of the photovoltaic power generation panel and the storage capacity of the battery. Get a string of numbers.

"Mr. Shen, we now have two types of solar panels, crystalline silicon and amorphous silicon. The power generation efficiency per unit area is about half, and the price is the same."

"I would also like to ask Mr. Zhao to introduce you carefully."

"Crystalline silicon solar panels have a power generation efficiency of 140 watts per square meter, and the price is about 500 yuan per square meter. Of course, this price includes all auxiliary equipment, but the price of the bracket is based on ordinary brackets. Forget it, if it is erected in the air at a height of several meters, there should be some more."

"The power generation efficiency of amorphous silicon solar panels is about 80 to [-] watts, and the price is more than [-] yuan per square meter. Which one do you want to choose, Mr. Shen?"

Of these two materials, crystalline silicon solar panels are obviously more cost-effective. The power generation efficiency of the same area is directly doubled, which can save a lot of laying area. Shen Yangguang directly chose crystalline silicon solar panels without hesitation.

Zhao Ming nodded, and then said: "Your road is ten meters wide. If you want to erect a roof, you can extend one or two meters to both sides, so that you can better shelter from wind and rain, and you can also lay a roof. More solar panels."

Shen Yangguang thought for a while and said: "The two sides extend 15 meters each, and the overall width is [-] meters. Is this no problem?"

"According to the power generation efficiency of 140 watts per square meter and the width of 15 meters, the power generation efficiency per meter of length is 20 watts. I have also calculated the power consumption of your three greenhouses. The overall need is more than 30 130 watts, less than [-] watts, so it is enough to lay about [-] meters, but I suggest to increase it slightly, just in case of power shortage.”

In addition to the need for electricity for the greenhouse in the orchard, there are also a series of equipment in the office. Shen Yangguang didn't want to calculate carefully. He directly gave the length of 200 meters, multiplied by the width of 15 meters, and the overall laying area reached [-] meters. square meters.
