When he left, Ye Nan fell into thinking, he was thinking about another thing, that is, the problem of new countryside and new energy.

The construction of the new countryside is easy to do, as long as the roads in the village are paved, as for the issue of new energy, Ye Nan once again fell into deep thought.

Biogas is only used as an energy source for fuel, and this energy source is interrelated with the lives of the villagers.

Therefore, this new energy source cannot guarantee people's normal life.

Ye Nan thought seriously, over the years, new energy has mainly been wind and water, but this is a basin, and feng shui obviously cannot be used as a resource.

Solar energy!

Ye Nan looked up at the sky and suddenly thought of the sun, only solar energy is inexhaustible.

Now that you have the idea of solar energy, you have to buy enough solar panels.

Of course, with these, it is still not enough, the voltage generated by Tianyang can be unstable, it needs to be stabilized, and the excess power also needs to be stored by batteries.

Once you have the idea, it's not a solar panel, it's a system.

Not to mention here, even in the city, or even in a larger city, the use of solar power by individuals is also a minority.

Therefore, Ye Nan not only needs the approval of some relevant departments, but also needs to have enough funds and enough places to bury solar panels.

There are many places on the mountain where solar panels can be laid, and these energy sources will be used as real yàn, first of all, he wants to let his villa use these things.

Thinking of this, Ye Nan didn't hesitate too much, he just wanted to investigate.

Of course, this was a few days later, and for the next few days, Ye Nan had been busy at school, all the time according to his plan.

So, he left the school under construction and went to Mohai City.

The purpose of his visit is to generate solar panels.

Mohai City is very large, but this market is very small, because, without a systematic guidance, it is too difficult to make money with these things.

Of course, if you don't buy much, the price is relatively high.

Ye Nan was in a building materials market and finally found a small store for sale of solar panels.

Ye Nan stood at the door and saw that the boss was sleeping, so he didn't bother rashly.

"Bangbang!" After Ye Nan made sure that there was no second person, he knocked lightly on the door.

The middle-aged man opened his eyes in a daze, saw someone coming, stood up, and pushed the chaise longue aside energetically.

"Sir, are you going to buy solar panels?" The middle-aged man said very happily, and took Ye Nan inside.

"Hmm." Ye Nan gave a gentle sigh of encouragement and followed in.

"Sir, what do you need, is it a whole system, or just solar panels?" The middle-aged man asked Ye Nan's intentions.

"The whole system." As Ye Nan spoke, he saw several solar panels of the whole system.

"There are a few of them, you can take a look."

"What's the maximum power of this?" Ye Nan asked casually.

"The most powerful one we have here is 120 watts, and a single panel alone is worth more than 400." The boss said this, so he showed Ye Nan that product.

"How much does this set cost?" Ye Nan looked at a style and asked.

"Ten thousand."

Ye Nan nodded, there are more than 10,000 sets, and the price is okay.

This system consists of two solar panels, a solar controller, a storage battery, and an inverter.

These things are necessary, as long as the battery panel is added, the others do not need to be added at all.

Battery panels, a good one, are only four or five hundred, and if they are average, they are about three hundred.

"You tell me which battery is the best."

The battery is the most critical, because Ye Nan's idea is that this electrical energy will be used in his house, so the battery must be large enough.

"It depends on how old you are."

"How big it is, show me." Ye Nan is also not very clear about the industry standards.

"This is the best, made in Germany, in all aspects, it is much better than the others, but in terms of price, it will be more expensive." The boss, instead of taking the ordinary, showed him this kind of battery produced in Germany.

Ye Nan nodded, the German industry is very strong in the first place, and the quality of their products can generally be guaranteed.

"That's what I'm going to do." Ye Nan didn't hesitate too much and made a decision directly.

"This one thing, but it costs 12,000, and I won't buy one point less." The boss said this and shook his head, this price, ordinary people will retreat directly when they hear it.

Ye Nan thought for a while, "Twelve thousand is fine, and you have to give me other things." Ye Nanxiang put forward his own idea.

The boss fell into deep thought, because he couldn't make a rash decision, and when he made money, he had to make it clear.

"No, 12,000 is too low, so let's see how much it costs to add other things." The boss said this and began to calculate.

Although Ye Nan didn't know the specific numbers he was calculating, he knew that since he wanted to do this business, he would not lose money.

"Fifteen thousand, you take everything." The boss said happily.

"I'm going to buy a lot of panels, and you give a good price." Ye Nan is not stingy, and he can't spend money indiscriminately.

"How many pieces do you need, do you need someone to install them?"

In general, if a person wants more solar panels, they will be delivered to the door and installed.

In the mountainous area, Yejia Village.

"Mountain villages have to pay for installation."

Ye Nan nodded, "This is no problem." "However, now I don't install, and in a few days, I will start installing."

"I'll give you a 20% discount, this is the lowest discount, no, forget it."

Ye Nan nodded, "Okay, cash on delivery, at the latest, I'll give it to you the next day." ”

"That's fine." The boss readily agreed.

"How many pieces?"

"Let's get a hundred dollars first." Ye Nan thought about it, a hundred yuan is not much.

"One Hundred ...... Block? The boss looked at Ye Nan in disbelief.

"Yes, a hundred." Ye Nan nodded heavily.

The boss looked at Ye Nan in surprise, what kind of person is this, he actually bought so much in one go, of course, the boss was very happy.

"There must be a deposit for this, you can pay a deposit of 20,000 yuan." The boss didn't think much about it, so he asked him to pay a deposit of 20,000 yuan.

"This one does."

Ye Nan agreed.

"Okay, you want that much, we have to sign a contract." The boss said, printing out a few pieces of paper on the computer, on which were some basic contracts.

"I don't have the money on me for the time being, otherwise, you will go to our Yejia Village tomorrow with some products, and when the time comes, if you think it's okay, you can continue to sign the contract, if not, I'll change to another one." Ye Nan didn't force him, after all, it wasn't easy for everyone.

The boss thought about it seriously, and it took him half a minute before he spoke, "Okay, I'll go to your village tomorrow." ”

Ye Nan nodded, and the most important thing was solved.
