1
00:00:01,750 --> 00:00:09,540
Hi everyone welcome back to BP Solar Energy of course it is a lost previous to a lecture we already

2
00:00:09,550 --> 00:00:19,330
discussed the ZBB sizing we understood that maybe sizing is a way used to give us the exact rating called

3
00:00:19,480 --> 00:00:29,780
each components or BP says that such as battery inverter solar charger controller and number of panels.

4
00:00:29,830 --> 00:00:33,430
There are c v v sizing missiles.

5
00:00:33,430 --> 00:00:41,380
The first method is by using Excel sheet like this one where they discussed in their second lecture

6
00:00:41,500 --> 00:00:47,650
or by using manual configuration as we already understood in their first lecture.

7
00:00:47,640 --> 00:00:53,470
In this section now we are going to use Peavey source software program.

8
00:00:53,470 --> 00:01:01,630
This program is the easiest way to describe as a v v system according to several angles.

9
00:01:01,720 --> 00:01:05,370
This is the BP source software premium.

10
00:01:05,440 --> 00:01:15,350
This software helps you to provide every sizing to three connected or standalone system I'm using the

11
00:01:15,360 --> 00:01:19,930
be sold premium software version seven point five.

12
00:01:19,930 --> 00:01:23,860
This version is used for great connected system only

13
00:01:27,000 --> 00:01:30,770
this is a welcome mat of Z self to it.

14
00:01:30,830 --> 00:01:37,450
Right here you can find out exactly the source of to your premium use the four great connector system.

15
00:01:37,490 --> 00:01:45,560
This is used to introduce to the program right here you can add new project or orbit or the project

16
00:01:45,800 --> 00:01:55,220
or you can open the recent projects or you can build in an example project from Z example project in

17
00:01:55,220 --> 00:01:57,210
Z system.

18
00:01:57,290 --> 00:02:02,380
Second that is a project there criteria can and is a project data.

19
00:02:02,420 --> 00:02:06,700
First of all project number let's call it one.

20
00:02:06,910 --> 00:02:14,290
The first project that is designed to meet John customer number.

21
00:02:14,340 --> 00:02:17,130
Let's say the first customer number.

22
00:02:17,160 --> 00:02:19,650
This is the contact person.

23
00:02:19,650 --> 00:02:23,320
The company is New Way Academy.

24
00:02:23,430 --> 00:02:29,900
You can add any that you want the phone let's say zero defects is zero.

25
00:02:31,630 --> 00:02:35,580
Email zero and the address is zero.

26
00:02:36,820 --> 00:02:38,940
You can add your data right here

27
00:02:43,260 --> 00:02:48,420
the project started in twenty seven all six of 2019.

28
00:02:48,680 --> 00:02:50,080
The project name.

29
00:02:50,240 --> 00:02:57,920
We are going to do great connected project as we already understood that.

30
00:02:58,110 --> 00:02:58,910
Oh great.

31
00:02:58,970 --> 00:03:04,030
Sister connect you can form right here as a project image.

32
00:03:04,030 --> 00:03:10,930
If you had the project image in your computer right here the grid connected this project description

33
00:03:11,140 --> 00:03:21,710
I'm doing great connected project for a living key to walk speak and you can write this off in a stylish

34
00:03:22,230 --> 00:03:22,950
right here.

35
00:03:24,850 --> 00:03:33,680
Second thing we are going to do what is the climate and the grid and system type from right here and

36
00:03:33,680 --> 00:03:37,800
you can put Z country.

37
00:03:37,960 --> 00:03:40,230
I'm going to choose country.

38
00:03:40,230 --> 00:03:49,840
Let's say Germany as it or as a location we are going to choose bowling.

39
00:03:50,050 --> 00:03:53,840
You can choose any location you want from right here.

40
00:03:53,860 --> 00:03:54,610
This icon

41
00:04:00,680 --> 00:04:09,140
of course the exact temperature and the data from out and latitude and longitude and the coefficient

42
00:04:09,140 --> 00:04:11,580
performance from right here.

43
00:04:11,720 --> 00:04:13,970
You can add by zip code

44
00:04:17,640 --> 00:04:20,850
sensing is the type of design.

45
00:04:20,850 --> 00:04:22,700
There are two types of design.

46
00:04:24,140 --> 00:04:33,110
By entering the data or by using 3D design I don't prefers 3d design so I'm going to use enter that

47
00:04:36,600 --> 00:04:45,460
zealous thing in this that is choosing the type of the system this of two premium seven point five is

48
00:04:45,460 --> 00:04:48,820
used to only food great connected TV system.

49
00:04:48,820 --> 00:04:56,040
I'm going to add that beefy salt software premiums used for direct connected with this system and stand

50
00:04:56,050 --> 00:04:57,910
alone in resources.

51
00:04:57,910 --> 00:05:05,320
So go to resource download the program and start doing what I'm doing now.

52
00:05:05,320 --> 00:05:15,710
I'm going to grid connected TV system Fulford and you can choose the grid connected with small loot

53
00:05:17,530 --> 00:05:22,210
or direct connected with loot and with battery.

54
00:05:22,360 --> 00:05:34,140
I'm going to with grid connected totally fit and you can enter Z type of E C means supply of grid.

55
00:05:34,160 --> 00:05:40,870
I am on two hundred and seventy volt three figures PA factor is one the maximum.

56
00:05:40,910 --> 00:05:48,300
We had no clinic.

57
00:05:48,520 --> 00:05:57,300
Second thing we are going to do is entering the b v module types were doing managed selection and waiting

58
00:05:57,310 --> 00:05:57,790
for

59
00:06:00,460 --> 00:06:05,790
loading.

60
00:06:06,010 --> 00:06:15,220
You can from right here choose any type of company producing beefy banner I'm going with some PA company

61
00:06:16,000 --> 00:06:16,690
right here.

62
00:06:17,670 --> 00:06:24,630
I'm going to choose the model is B or E twenty two one hundred and forty five.

63
00:06:25,050 --> 00:06:32,700
You can find that a sheet of some power this model by choosing this icon.

64
00:06:32,910 --> 00:06:40,680
As you already see in this tab you find any type of companies we are really choosing some part is B

65
00:06:40,710 --> 00:06:45,660
or E twenty two hundred and forty five of the company calls some.

66
00:06:45,780 --> 00:06:52,650
That power rating is two hundred and forty five for the maximum power play in voltage is forty point

67
00:06:52,650 --> 00:06:57,030
five involved and maximum power point current is six point all five.

68
00:06:57,050 --> 00:06:58,390
Empire.

69
00:06:58,510 --> 00:07:01,620
This one is evil so going with this

70
00:07:05,680 --> 00:07:09,660
there are two ways of entering module area.

71
00:07:09,670 --> 00:07:13,720
First type by drawing is a graphical coverage.

72
00:07:13,720 --> 00:07:21,780
Second type by that that data input we want to use exists generator for living king.

73
00:07:21,860 --> 00:07:22,640
While it

74
00:07:26,150 --> 00:07:39,400
so we can use number of BBM modules equal to 45 modules orientation is one hundred and eighty degree

75
00:07:39,790 --> 00:07:43,810
mean go to South said.

76
00:07:43,820 --> 00:07:51,170
Total is about 30 degree you can find from here.

77
00:07:51,230 --> 00:07:56,650
That type of mounting roof Pearl or mounted roof.

78
00:07:56,750 --> 00:07:58,580
We are going to choose multitudes

79
00:08:03,760 --> 00:08:11,360
the degradation of the module because as you see that modules is already mounted onto the roof so as

80
00:08:11,380 --> 00:08:20,730
there is no shading right here sensing we are going to do is the degradation of the module the meaning

81
00:08:20,730 --> 00:08:28,620
of the gradation is the precision of the modules means the power of the modules is going down into an

82
00:08:28,630 --> 00:08:39,960
easier by say for 20 years going to 80 percent of Zumwalt you mean 1 percent for each year now we are

83
00:08:39,980 --> 00:08:48,620
see the the modules going to the next one is selecting Zane vert from this step to select Zain Verjee

84
00:08:49,560 --> 00:08:52,240
you can select any type from right here.

85
00:08:52,330 --> 00:08:53,020
Select

86
00:08:57,260 --> 00:09:02,660
you can add or remove any type of modules from right here

87
00:09:06,800 --> 00:09:14,290
and I'm going to choose the inverter of APB this one and this third calculation

88
00:09:17,160 --> 00:09:27,200
we have different calibration of this methyl first timers is the modules by using surface three hundred

89
00:09:27,200 --> 00:09:36,020
what we are going to use three modules each module is connected in series with 15 module

90
00:09:39,360 --> 00:09:48,510
the second type is 40 hundred What is less calibrated put Xen is the first one because as you see right

91
00:09:48,510 --> 00:09:58,650
here they can be pretty is about 85 percent right here is eighty one percent is going down so is the

92
00:09:58,650 --> 00:10:06,440
best one is the first one this one B V S 300 T.

93
00:10:08,120 --> 00:10:09,570
Thirty three hundred.

94
00:10:09,570 --> 00:10:20,880
What two we are going to use three inverters a chain voter is connected to 15 modules and we already

95
00:10:20,880 --> 00:10:30,320
choose this one each a strength or each inverter is connected to strength and Asia steering is consist

96
00:10:30,320 --> 00:10:41,450
of 15 modules ensues as shown right here seven saying we are going to choose is a type of a cable we

97
00:10:41,450 --> 00:10:54,850
can as Z cable losses from right here directly or by diesels let's say in details we have two types

98
00:10:54,850 --> 00:11:05,200
of cables easy cable and DC cable first list a thought by AC keep their meter is this thing as far from

99
00:11:05,350 --> 00:11:12,720
the inverter let's say twenty five meter we are using cover wire of four millimeters squared.

100
00:11:12,820 --> 00:11:22,410
We are using circuit breaker and residuals comms device what are you using in BBT 1 and is a number

101
00:11:22,590 --> 00:11:34,190
of the ambulance under the tracker is for 3 for each string and 1 common for the count you can add from

102
00:11:34,190 --> 00:11:42,920
here the isolated later 0 are two types of isolated first isolated implemented is the inverter like

103
00:11:42,930 --> 00:11:47,190
this one or so variously from the inverter I'm using says separately 1

104
00:11:50,420 --> 00:11:59,030
we are going now to the second type is a cable that DC cable or string killed let's say we are using

105
00:11:59,510 --> 00:12:09,640
cable connected between Z drink and Z inverter let's say 5 meter of 4 millimeter squared square cover

106
00:12:12,990 --> 00:12:16,330
you can choose one less than for a.

107
00:12:16,380 --> 00:12:23,730
We are going choose 2.5 and we have to choose for this one is six millimeter squared is better than

108
00:12:23,790 --> 00:12:26,550
fourth.

109
00:12:26,690 --> 00:12:34,700
Now we are going to draw as a circuit diagram of this one from this tap as you see you can draw a the

110
00:12:34,740 --> 00:12:47,310
wrong let's say the second diagram ignore waiting this as the circuit diagram of the outburst we are

111
00:12:47,310 --> 00:12:56,640
using three inverters each inverter connected to string it just strength consist of 15 modules in serious

112
00:12:58,720 --> 00:13:06,500
the cable connected between the strengths and the inverter is five meter as a cross section area is

113
00:13:06,500 --> 00:13:12,830
two point five millimeter squared to getting connected between the inverter and the meter is twenty

114
00:13:12,830 --> 00:13:16,690
five meter of Cross section area six millimeters squared.

115
00:13:16,800 --> 00:13:19,540
This is the residual current device.

116
00:13:19,610 --> 00:13:22,060
This one is the circuit breaker.

117
00:13:22,070 --> 00:13:24,200
This one is circuit breaker.

118
00:13:24,200 --> 00:13:25,900
This one is isolated.

119
00:13:26,330 --> 00:13:35,690
You can find inside the right put on that type of the system and z table as a source Z system output

120
00:13:36,460 --> 00:13:47,390
that company and system address created boy approved by port number and the title of this project and

121
00:13:47,390 --> 00:13:49,780
the number of sheep and the issue.

122
00:13:50,900 --> 00:14:03,020
This that is used for financial analysis according to any country has at any kind of fees and financial

123
00:14:03,020 --> 00:14:03,860
analysis.

124
00:14:03,860 --> 00:14:12,350
You can't choose you or financial assets from right here I'm leaving it as it is then we are going to

125
00:14:12,380 --> 00:14:13,210
calculation

126
00:14:22,440 --> 00:14:32,980
from right here you can find that total energy or production for cost is a whole leave into January

127
00:14:33,070 --> 00:14:38,370
and December has the lowest energy in the entire year.

128
00:14:38,470 --> 00:14:48,610
But in May has the highest value is about fifteen hundred kilowatt hour Z total energy in the year is

129
00:14:48,610 --> 00:14:56,370
about eleven thousand three hundred and twenty seven kilowatt hour Z amount of energy beer.

130
00:14:56,370 --> 00:15:03,110
Q What beat is equal to one thousand twenty six point nine kilowatt hour.

131
00:15:03,110 --> 00:15:09,490
B A kilowatt the middle form and c issue is about 88 percent

132
00:15:13,110 --> 00:15:18,510
energy from grid is about 44 kilowatt hour per year.

133
00:15:20,310 --> 00:15:25,140
And ZB system is four point eleven kilowatt hour.

134
00:15:25,310 --> 00:15:33,080
Very you can find the right use it in preacher in the entire year.

135
00:15:33,170 --> 00:15:44,000
The look of is for that I would cite in preacher or Satan preacher for any variant of zero.

136
00:15:45,130 --> 00:15:52,880
Or you can find Z module temperature is the rate curve as you already understood from Z.

137
00:15:53,080 --> 00:16:01,880
Second Section Z Z due to pressure must be greater than the outside temperature dependent on the of

138
00:16:01,930 --> 00:16:06,040
solar radiance and ambient in breach.

139
00:16:06,250 --> 00:16:12,260
Second thing you can find right here is the solar radiance value on the entire year.

140
00:16:12,380 --> 00:16:17,220
This is January and this town has the lowest value of their solar radiance.

141
00:16:17,820 --> 00:16:24,730
But in May and June and July you'll find XYZ value of the Z solar radiance.

142
00:16:24,820 --> 00:16:34,770
The blue curve is used for a radius until horizontal Glenn this curve is used to for a radius onto the

143
00:16:34,790 --> 00:16:36,000
satellite surface.

144
00:16:36,040 --> 00:16:43,950
You can find right here is a performance ratio the performance ratio is going between eighty eight percent

145
00:16:48,160 --> 00:16:55,530
you can find the right here's the beat the system energy balance Z relation between Z input energy and

146
00:16:55,530 --> 00:16:57,820
the losses to give us all good energy.

147
00:16:59,450 --> 00:17:00,830
We have is a little bit.

148
00:17:00,850 --> 00:17:06,650
All right this is one thousand forty two key to what our beer meter squared.

149
00:17:06,650 --> 00:17:09,620
We had division losses from the standard.

150
00:17:09,620 --> 00:17:15,930
Spectrum is about minus ten point forty two kilowatt very meter squared.

151
00:17:15,930 --> 00:17:24,170
You mean that global or ideation as a module must be equal to one thousand one hundred sixty eight point

152
00:17:24,170 --> 00:17:25,830
five kilowatt hour.

153
00:17:25,870 --> 00:17:31,690
It needs a split we are already using for five modules.

154
00:17:31,680 --> 00:17:40,320
Those four to five modules covers an area about fifty six meters squared so fifty six meters squared

155
00:17:40,350 --> 00:17:45,100
times one thousand one hundred sixty eight point five.

156
00:17:45,120 --> 00:17:53,970
Q What our parameters glad will give us suggestive five cells in four hundred fifteen point four kilowatt

157
00:17:54,090 --> 00:18:03,540
hour we have losses according to its DC conversion as the rated efficiency of the modules is about nineteen

158
00:18:03,540 --> 00:18:11,610
point seven percent times as value you can multiply that nineteen point seven percent times this is

159
00:18:11,610 --> 00:18:19,770
very you'll find out that rated b the energy is about twelve thousand eight hundred and eighty three

160
00:18:19,770 --> 00:18:27,840
point seven kilowatt hour we have low light performance losses and division losses from Z no mean then

161
00:18:27,840 --> 00:18:35,490
Module Two pressure and diet losses and mismatch according to manufacturer information and mismatch

162
00:18:35,580 --> 00:18:45,240
do according to shadow because we already leaning on the roof so their schedule mis mesh losses is equal

163
00:18:45,240 --> 00:18:55,890
to zero to sustaining cable or DC cable has losses about minus two point to five kilowatt hour so that

164
00:18:56,230 --> 00:19:06,060
outward energy ought to be v energy DC without inverter is equal to twelve thousand ninety six point

165
00:19:06,120 --> 00:19:12,590
eight kilowatt hour by ending Z maximum power by.

166
00:19:13,270 --> 00:19:23,570
You'll find out z b v energy C without inverter is about twelve thousand eighty two kilowatt hour

167
00:19:27,220 --> 00:19:36,490
after adding to the losses of the inverter such as Z voltage division and DC AC conversion efficiency

168
00:19:36,880 --> 00:19:40,020
as a stand by consumption and easy.

169
00:19:40,040 --> 00:19:49,840
Cable losses you'll find out z z then V energy E C minus this then the boy use is in eleven cells in

170
00:19:50,220 --> 00:19:53,580
two one hundred eighty three kilowatt hour.

171
00:19:53,920 --> 00:20:02,920
By adding Z standard by consumption or forty three point five it you will find out Z great fit n is

172
00:20:03,100 --> 00:20:13,920
eleven thousand three hundred twenty six point seven kilowatt of the last step is for financial analysis

173
00:20:14,280 --> 00:20:22,460
according to your country you can find right here that financial analysis the B vision greater outward

174
00:20:22,820 --> 00:20:30,890
and Z start of Operation and return ends a total investment of course you need and the incoming net

175
00:20:31,360 --> 00:20:34,520
subsides and of course and so on.

176
00:20:36,990 --> 00:20:45,930
You can find the cash flow table for each year first year you had to be Z investment cause they export

177
00:20:45,930 --> 00:20:56,730
trophies give you about one million pound and so on for a second year 30 years for CFC is six year seven

178
00:20:56,730 --> 00:21:04,350
year as on you can find the year the cash flow as you already can see it.

179
00:21:04,640 --> 00:21:10,730
And as for teen year you can find the first proper return of

180
00:21:14,520 --> 00:21:16,260
after 14 years.

181
00:21:16,320 --> 00:21:19,740
You can find the first profit return

182
00:21:23,310 --> 00:21:35,100
the lost 14 year helps you to get Z investment cost so less debt is used to give you that view presentation

183
00:21:35,280 --> 00:21:45,710
to the project mean that that sheet of the project can find right here in the first page Z.

184
00:21:46,080 --> 00:21:50,360
Project name the company client

185
00:21:53,650 --> 00:21:56,000
is a phone and email and contact the better some

186
00:21:59,980 --> 00:22:07,670
ends a project Iris as a start or completion date and project description.

187
00:22:09,140 --> 00:22:17,680
It is a second page you can find that great connected TV system that I was at B V system and the climate

188
00:22:17,680 --> 00:22:25,210
date and DMV visionary to Parliament is about 11 kilo what their peak

189
00:22:28,400 --> 00:22:32,730
their surface area is fifty six meters square.

190
00:22:32,730 --> 00:22:38,780
We are using forty five modules and three number of converts.

191
00:22:38,780 --> 00:22:42,030
This is the same single diagram of our system.

192
00:22:43,160 --> 00:22:47,940
Zale is eleven thousand and hundred twenty seven kilowatt hour.

193
00:22:47,990 --> 00:22:57,270
Barry their performance issue is about 88 percent their total cost investment.

194
00:22:57,270 --> 00:22:59,310
Is this 1 0.

195
00:22:59,320 --> 00:23:04,530
Their this percentage after sixteen point seven years.

196
00:23:04,530 --> 00:23:06,450
You can find that first the profit

197
00:23:09,220 --> 00:23:19,910
second pitch is used for setup of the systems and b v module area and losses and the inverter easy man

198
00:23:19,920 --> 00:23:20,670
supply.

199
00:23:21,420 --> 00:23:22,030
As a kid

200
00:23:25,170 --> 00:23:28,120
you can find right here the simulation results.

201
00:23:29,370 --> 00:23:30,990
Such as the system.

202
00:23:32,230 --> 00:23:40,900
This is the curve of production for cost general area and the sound has the lowest value and the army

203
00:23:40,900 --> 00:23:42,180
has the highest value

204
00:23:48,510 --> 00:23:49,080
you can find.

205
00:23:49,080 --> 00:24:00,080
The idea is that BP Solar energy balance Z total and Billboard said that output both according to several

206
00:24:00,080 --> 00:24:08,380
type of losses you can find the right here's the financial analysis and the cash flow you can find right.

207
00:24:08,420 --> 00:24:18,080
Here's a cash flow table and right here ZBB module is from a company called SunPower solar type is monetarist

208
00:24:18,080 --> 00:24:26,700
the line cell phone number of cells in each module is 22 number of Bibles out in each module.

209
00:24:26,700 --> 00:24:37,140
These three Z dimension of Z modules is one this module is families has no frame.

210
00:24:37,310 --> 00:24:43,710
So I take care of the maximum boilerplate voltage and maximum Burbank grant and a maximum boilerplate

211
00:24:43,910 --> 00:24:44,400
power.

212
00:24:46,390 --> 00:24:49,320
Zelman circuit voltage at all shorted current

213
00:24:53,130 --> 00:25:00,770
under us of that phraseology you can fry anything right here is it as a sheet of the inverter.

214
00:25:00,780 --> 00:25:10,190
It is from a company called ABC as NBC polar rating is three point four is the ABC board rating is three

215
00:25:10,190 --> 00:25:11,080
point three.

216
00:25:11,270 --> 00:25:16,700
The efficiency of this inverter is about three point three over city point for

217
00:25:20,180 --> 00:25:28,060
you can find right here as a nominal DC voltage and the medicine input voltage and Mesa and we'll and

218
00:25:28,120 --> 00:25:37,920
feet and from us on you can find that out right here is their maximum power plant tracker that is sheets

219
00:25:37,980 --> 00:25:46,840
right here lust saying we are going to discuss in this that a sheet is that you can find right here.

220
00:25:46,850 --> 00:25:48,100
The single line diagram

221
00:25:52,390 --> 00:26:03,300
this never showed you can export as PBF or even the more you can find this result in simulation Excel

222
00:26:03,300 --> 00:26:04,470
sheet.

223
00:26:04,530 --> 00:26:08,640
I hope you had the agreed benefit of this course.

224
00:26:08,640 --> 00:26:19,790
I hope you understood new information about V V systems is a Z on grid or standalone b v system.

225
00:26:20,870 --> 00:26:27,650
And understands that devious system component and how to choose every component.

226
00:26:27,710 --> 00:26:30,010
I hope you have fun with us.

227
00:26:30,680 --> 00:26:32,090
Thank you for listening.

228
00:26:33,060 --> 00:26:44,420
And if you had any problems please don't hesitate to ask us any question and we will help you with answer.

229
00:26:47,200 --> 00:26:48,550
Thank you for listening.

230
00:26:49,360 --> 00:26:51,100
See you in the next course.
