After looking forward to the upcoming good life for a while, Hu Zhao was still pulled by Guan Ning to drink a little wine. The effect of this alcohol on the nervous system suddenly made both of them feel a lot more interested.

After the strings in their heads loosened, what the two of them said became unscrupulous.

"Say, why did the lord send the two of us to this place where birds don't?"

Hearing Guan Ning ask, Hu Zhao didn't think much about it, and immediately replied: "Who said that birds here don't." There is no human industrial pollution here, so how can there be no birds that everywhere. ”

Guan Ning smiled and said nothing, the focus of what he said was, of course, not the issue of the birds' exclusion.

Seeing that his face was starting to become serious, Hu Zhao couldn't help but feel a little surprised in his heart, and hurriedly asked, "What problem did You'an have in mind?" ”

"Exactly." Guan Ning took a bite of the rabbit meat in his hand and replied, "We are just setting an example for those who come after us." ”

"Role models?" Hu Zhao didn't understand it.

Guan Ning then explained: "Do you see what our lord means, like someone who is ready to be in a corner of peace? Sooner or later, they will have to develop externally. We're just the first people to be tasked with finding the way. What we are going to do now will be repeated countless times in the future. Those who come after will begin to explore on various planes, extending our empire into an infinite expanse of time and space. ”

"I see." Hu Zhao stood up and said, "We are pathfinders. What we are doing now will be the object of imitation by those who come after us. In this way, our task is of great significance. ”

"Of course." Guan Ning smiled, "I think it's better to write a diary of everything that will happen here, so that it can be used as a reference for later generations." In addition, we also have to record the experience in practice and condense it into another book, if necessary, to help those who come after us to speed up. ”

Hu Zhao clapped his hands and exclaimed, "This is a good idea. Just do as you say."

There was nothing to do, and the two gathered around the campfire and discussed carefully.

Even if the direction has been basically determined, and an accurate map of the Survey Office is needed, it must be necessary to have modern equipment such as total stations, and this equipment will not be able to be shipped with logistical supplies such as seeds and building materials in the near future, so all that can be done now is to simply look up and look for the North Star.

At this time, solar panels that have been exposed to the sun for a while during the day can already come in handy. More than a dozen small LED bulbs that are more energy-efficient are suspended. Several of the tents were also lit up. This made the camp a bright area that few people dared to approach easily in a short time. Of course, insects such as mosquitoes with strong phototaxis can only fly here faster, so Qin Han can only carry insecticides to each tent for slaughter.

Hu Zhao still admires the solar power business. However, according to Guan Ning, the lords' requirements for the solar energy industry do keep everyone clear-headed.

Although the one-time input cost of solar power generation is relatively high in small-scale use, the practicability has been greatly improved with the development of technology. However, in terms of large-scale power generation, solar energy intermittent, variable, random and other factors from the light aspect restrict its effective development. In the field of small-scale long-distance power transmission, the most serious problem caused by these characteristics is voltage instability, and then too much line loss.

Therefore, despite the various benefits of solar power generation, such as energy conservation and emission reduction, green pollution-free, etc., we must remain rational when looking at its development.

There are a lot of face-saving projects now, such as solar street lights in cities, and solar-powered cars in some government agencies -- the kind with internal combustion engines. Why bring an internal combustion engine? Because the solar electric equipment is too big, it can't be carried by itself, so it has to be pulled by the internal combustion engine. In this way, the internal combustion engine of a car was used to tow the vehicle itself and people, but a set of weight and equipment was added to this. If this can be regarded as urban energy conservation and emission reduction, it is really a hell of a life.

As for the solar street lamp, the author of this kind of small citizen suddenly felt tall and high, and there was a feeling of uncertainty. But when I went out, I found that it was not bright, why? God is not happy, it's cloudy.

This solar street lamp, to put it bluntly, means that the government takes the procurement authority in its hands to support some industries that are still profitable in the future. This is not possible in a complete market economy. But in our country, this kind of thing is not uncommon.

It is true that this system points out the direction for the healthy development of the industrial chain, but it does not necessarily report its fairness and reasonableness, resulting in many people looking for loopholes from it. For example, Sun Luo got this small solar power generation project.

Sun Luo's R&D this time is purely based on earth technology. Who let the celebrity group have a state-owned solar photovoltaic production plant, and it is the kind that almost collapsed. It was only after Sun Luo injected him a large amount of money that the manufacturer resumed production. At present, Hu Zhao and others are using products under the new technology.

In the past, this factory was a victim of imperfect competition, but now after he rises again, he will come out to take revenge.

Compared with the common ones in the market, solar panels can last for 15 to 20 years. Xingmao Group's products will be used for ten years at most, and the reason is very simple. Because ten years later, Sun Luo will definitely update and research the next generation of products with Saturn's technological characteristics. And now there is no need to invest more in costs.

On the other hand, in terms of material selection, Xingmao Group uses cadmium telluride thin-film solar panels. The cost is about $0.7 per watt. That's seven hundred dollars per kilowatt. In ten years, or more than 80,000 hours, it seems that each kilowatt-hour of electricity is less than a penny, that is, less than a dime. In fact, there is still a market.

Of course, other facilities may not be free. Counting solar panels alone is definitely not a no-go.

Other components of the solar power system are the preservation unit, which is mainly used to store electrical energy, which is generally undertaken by the battery; Controller, to ensure that the power generation process has been in a relatively efficient state, the current charging control technology generally adopts pulse width modulation technology, that is, PWM control mode; The inverter, this thing turns the direct current coming out of the battery panel into the alternating current that we usually use.

The production standard of Xingmao Group is naturally in accordance with the standard of 220V and 50HZ.

Add these costs to the next level, and in the best case, the price per kilowatt-hour is relatively close to the market price.

It seems that there is still a certain competitiveness, but once combined with the actual situation, we can see that the pit people are coming.

This set of technology is equivalent to the need for users to pay the electricity bill for the next ten years at once, who does not use the country's electricity first, and then pay the money, who can afford such an investment.

Moreover, there is a major flaw in this way of calculating. That is, whether the power generation can meet the needs of users.

Tens of watts for TVs, hundreds of watts for computers, refrigerators and air conditioners, and more. How many such power generation units are needed to meet the needs of users at the same time, rather than letting you bathe in the sun for ten years and then pass it on to the electrical appliances.

Therefore, when theory is combined with practice, the original calculation is very ridiculous. The original hope for solar power generation is basically gone.

I don't know how big a panel that $0.7 per watt cost is calculated. (Du Niang Encyclopedia has always been very tricky) the same material of the battery panel, if there is a difference in the size of the area, the power must be different. Therefore, the cost should not only be how much money is per watt, but also how much area is occupied per watt.

Not to mention how expensive the house is now, there is simply no place to put these solar panels. Don't think that a spacious countryside is more suitable, where you can eat on the land, unless even the mountains where irrigation is not easy are planted with fruit trees, where is there empty space?

That is, in the 11th century, where the population density was not too high, there was enough space for it.

And don't forget to pay 10 years in advance for electricity.

So what other users will be able to meet such conditions?

Local tyrants, only local tyrants! A tyrant who owns a villa!

So we see that in recent years, the solar power market has either been 10 watts or 60 watts of gadgets, or products specifically for villa users.

Our small family generally doesn't make a flashy power generation system for a light bulb. Therefore, unless the conversion efficiency of solar panels can make a qualitative leap and ensure that we can provide enough power with a relatively small battery area, it is still difficult for this thing to enter thousands of households.

However, Hu Zhao knew that Sun Luo's ambition was definitely not only like this. Soon, swarms of solar panels may appear on the land of Da Viet country. And there's a good chance that it's free.

According to the current economic strength of Xingmao Group, although it is very difficult to achieve this, if there are some ingenious financing methods, it is not completely impossible for enterprises and institutions.

But another problem has arisen, the whole set of processing technology is currently on the territory of the splendid country. Could it be that the splendid country just watched the Great Yue Kingdom enter the electric age and was indifferent. Hu Zhao knew that the relationship between the strength of the two sides was very delicate, and of course Jinxiuguo did not want the power of the Star Cat Group to expand to the point where it was uncontrollable.

However, this kind of thing is not something that a small person of Hu Zhao's level can plan, so let Zhuge Liang worry about it.
