00:00 But I would also like to know why we are not defined by the number of panels that can be launched and in parallel, because it is important for the MPPT engine that we have chosen.
00:15 If I have chosen a MPPT of 150, the maximum voltage on the left side is 1, it means that I have to adapt the voltage of my panels by saying the voltage VOC,
00:36 to see the number of panels that I want to put in parallel so that it does not exceed, in short, so that it is in the range of the voltage acceptable by the regulator.
00:51 But I did not see this mention there, so it means that it is good to calculate the number of panels inserted in parallel.
01:01 No, we did not need that. In the calculation, we tried to integrate these parameters.
01:08 I don't know if you understand Mr. Mok.
01:13 Yes, but I didn't see the number of panels that tells me that I would need 3 panels in series and 2 groups of 3 panels in series to make 2 swings of 3.
01:25 I didn't see that.
01:27 And on the other hand, the battery, I saw.
01:31 Wait, let's go back.
01:33 At the level of the number of panels.
01:46 Yes.
01:56 I'm listening to you Mr. Mok.
01:58 Yes.
02:00 Ah, okay, that's good.
02:02 It's good, I didn't see it.
02:07 In fact, as your screen is tiny, I see it.
02:10 Yes, yes, yes.
02:12 I see the number of panels inserted, 13, and in parallel, 2.
02:18 Okay, okay.
02:20 That's where you ask your questions.
02:22 I didn't see these parameters.
02:24 Okay, that's good, I'll animate you in the evening.
02:29 I like it.
02:31 Thank you.
02:33 Well, we will continue.
02:35 Here we are.
02:38 We talked about simulation.
02:41 Well, the OECD offers two simulations.
02:46 Simulation and productivity.
02:50 And the schematic simulation, in fact, that is, how it will present itself physically.
02:59 Here we can see our production every month of the year.
03:07 Depending on the dimensioning we did.
03:10 We can notice that here, in green, we will have the surplus production over the year.
03:20 For example, in January, we will have a surplus of 15.98.
03:27 In fact, you can see, you can look at it with me, over the year, we have the surplus production.
03:36 Now, as a technician, you see, what is the purpose of the dimensioning?
03:46 Dimensioning according to what I need.
03:52 And we can notice that there is surplus production over the year.
03:57 Which means that we can still reduce the installation.
04:05 That is, if I reduce the installation, I will reduce the production.
04:10 The surplus production is just limited to what I need.
04:15 This will have the effect of reducing the cost of the installation, of course.
04:22 And I can tell you that if there is surplus production, it is because I chose an MPPT module.
04:29 If I had chosen an ondular that does not have the beach and MPPT, I would not have had surplus production.
04:38 Does anyone have a question?
04:42 Go ahead, Mr Mbom.
04:48 Wait a moment.
04:51 Yes, go ahead.
04:54 Mr Mbom.
04:57 You said you had a question.
05:15 Hello.
05:16 Yes, I'm listening.
05:18 You said that the part in green on this diagram is the surplus production.
05:24 Yes.
05:25 Okay.
05:27 As you said, the idea is to have a balanced system.
05:35 Yes.
05:36 Which will reduce the cost of investment.
05:41 Absolutely.
05:42 Because all the green energy will be lost.
05:46 In the case of injection or irrigation, is it possible to leave it like that?
05:54 Or is it not always important to leave it like that, to always have an installation?
