The strongest reserve for the doomsday

After eating, smoking, and starting the second half of the work in good spirits.

The battery, inverter, controller, and 220V switching controller of the solar power system have

been completed, and the outdoor base bracket of this system, the concrete underneath has also been solidified, and the bracket has also been completed.

Now the system is left with the laying of solar panels, reinforcement and the connection of solar panel circuits.

The solar panels are surrounded by aluminium and covered with tempered glass. Underneath is a monolithic aluminium plate, fixed with glass glue. In the middle are polycrystalline silicon solar cells.

Two wires are exposed on the back of the solar panel, one red and one black. Protruding from the back of the board, it is also fixed with glass glue.

Laying this solar panel is actually relatively simple.

First of all, the following frame should be built, this frame is very critical, a radish and a pit, and each solar panel should be placed just right, parallel to this bracket.

This allows you to proceed to the next step.

When a piece of solar panel is put into the stainless steel shelf, a long piece of stainless steel is used to press down along the aluminum alloy frame around the solar panel,

and then the solar panel and bracket are fixed with screws. All four sides are to be pressed with this stainless steel sheet.

Since there are screw holes in the solar panel, it is very strong and reliable to fix.

If a level 12 gale comes, even if the bracket is blown away, the solar panels on the bracket are still tightly fixed in the pit.

The bracket, I also call them the best and thickest bracket, the type with tempered glass and aluminum alloy wrapping for solar panels, I think this type is more reliable.

Those flexible solar energy may be more suitable for RVs, but they are easily damaged by external forces, and the power generation efficiency is not as high as mine.

That's why I chose this kind of solar panel. As for why the bracket is so expensive, it's because there is a lot of money, thank you.

The wiring of the solar panels is one board after another, because if you are all lined up at once, then you will not be able to connect the wires on top, and you will have to build a ladder underneath.

This is obviously not as convenient as picking up one piece at a time.

The wiring is underground, all of which are sleeved in the PVC pipe, and the waterproof tape is wound at the interface. It is then fixed to the aluminum plate on the back of the solar panel with 3M tape. The key parts are wrapped around the bracket with iron wire.

Finally, four thick wires extended from the outside of the house, estimated to be 6 square copper wires. Connected to two solar controllers.

I didn't expect this solar controller to show that it is charging...

This basking moon can also be recharged, which is quite surprising to me. But I don't think it can be filled much. Later, I found out that what was sunning the moon, it was a searchlight...

I've seen that the employees of these solar companies have used that kind of glass glue to seal the holes, after they've finished wiring.

I also asked Team Leader Yang to punch the glass glue into the joint gap of the solar panel bracket above, as well as the joint gap between the solar panel and the bracket, and then smoothed it with the board.

In this way, this has officially changed from a solar bracket to a sun canopy, and there will be no such thing as heavy rain on top and light rain below. Although there is no sunlight shining down in this sun canopy... But let's call it a sunshade for the time being.

With such a layer of glass glue, all the gaps on it are filled, so there is another benefit, so that the connection gap between each solar panel and the bracket is changed from a rigid connection to a flexible connection.

In this way, when the wind blows and swings, the solar panels can be better protected.

And Lao Wang's side, all the doors have been replaced with thick security doors, and the entrance door on the first floor has made me a double security door. . .

Anyway, as long as he has business, he will give me the materials desperately, and when the time comes, his income will come...

The windows are welded with anti-theft nets, this time all the anti-theft nets are welded on the façade, which is different from the city inside, I don't need to consider the situation of the façade, so it is better to install it outside.

Of course, the expansion screws are also driven, and then all the steel bars are welded to death, so although it is a little difficult to open the window, but fortunately, it is so solid. The windows can also be opened, but they can only be opened a little bit to let in air.

The courtyard gate, Lao Wang is also in line with the principle of more the merrier, originally to weld five stiffeners, in the background he bought me one get one free, directly higher than 10 stiffeners, up and down, all are steel bars, but also to my hinges to do reinforced, added 6 hinges, and the wall is firmly connected together.

When this is done, I will call everyone over for a ceremony that everyone loves—the transfer ceremony.

Everyone who was present gave me the account number, and then everyone transferred 1,500

yuan, and then it was checkout, and the solar company was 76,000 yuan, but because I used a lot of glass glue from them, and upgraded the frame material, I finally gave 80,000 yuan.

I have installed a total of 8 security doors here, as well as 12 security windows for windows, and the door reinforcement at the door.

He calculated, 4,000 yuan for one security door, 8 pieces, 32,000 yuan. One anti-theft window is 1,000 pieces, and 12 pieces are 12,000 pieces. The gate was reinforced, and I received 2,000 yuan.

So it's a total of 46,000 pieces.

Lao Wang said

, "I'm for safety, so the choice of this anti-theft door is an imported high-level

anti-theft door, so I chose a more expensive one, I'm sorry" "You're too careful, I just want a safer anti-theft door, it's okay to be more expensive"

So I transferred 46,000 yuan to Lao Wang, and also gave 4,000 yuan in benefits. It's their labor fee.

Lao Wang is such a person, he can see through your intentions, and then use this intention to guide you in his favor.

Just like this time, when I heard about 4,000 yuan a door, I must feel very expensive, I must have to bargain. Lao Wang said it himself first, it was for my good and my safety that he chose this model, and he was also very embarrassed, for my consideration.

If you look at it like this, I won't feel expensive, but I think Lao Wang did the right thing, and I want this kind of good thing. You see, I ended up paying another 4,000 benefits.

It wasn't until later that I found out that the TMD anti-theft door import was imported, but the market price was only 3000 yuan, this old Wang... What's even worse is that I forgot to give a deposit of 5,000 yuan in advance...

Throughout the afternoon and evening, the power system and safety reinforcement were completed, but at the cost of 127,000 dollars...

After sending the money and inspecting the goods, everyone went back to their respective homes and looked for their own mothers.
