Hi everyone welcome back to BP Solar Energy of course it is a lost previous to a lecture we already
discussed the ZBB sizing we understood that maybe sizing is a way used to give us the exact rating called
each components or BP says that such as battery inverter solar charger controller and number of panels.
There are c v v sizing missiles.
The first method is by using Excel sheet like this one where they discussed in their second lecture
or by using manual configuration as we already understood in their first lecture.
In this section now we are going to use Peavey source software program.
This program is the easiest way to describe as a v v system according to several angles.
This is the BP source software premium.
This software helps you to provide every sizing to three connected or standalone system I'm using the
be sold premium software version seven point five.
This version is used for great connected system only
this is a welcome mat of Z self to it.
Right here you can find out exactly the source of to your premium use the four great connector system.
This is used to introduce to the program right here you can add new project or orbit or the project
or you can open the recent projects or you can build in an example project from Z example project in
Z system.
Second that is a project there criteria can and is a project data.
First of all project number let's call it one.
The first project that is designed to meet John customer number.
Let's say the first customer number.
This is the contact person.
The company is New Way Academy.
You can add any that you want the phone let's say zero defects is zero.
Email zero and the address is zero.
You can add your data right here
the project started in twenty seven all six of 2019.
The project name.
We are going to do great connected project as we already understood that.
Oh great.
Sister connect you can form right here as a project image.
If you had the project image in your computer right here the grid connected this project description
I'm doing great connected project for a living key to walk speak and you can write this off in a stylish
right here.
Second thing we are going to do what is the climate and the grid and system type from right here and
you can put Z country.
I'm going to choose country.
Let's say Germany as it or as a location we are going to choose bowling.
You can choose any location you want from right here.
This icon
of course the exact temperature and the data from out and latitude and longitude and the coefficient
performance from right here.
You can add by zip code
sensing is the type of design.
There are two types of design.
By entering the data or by using 3D design I don't prefers 3d design so I'm going to use enter that
zealous thing in this that is choosing the type of the system this of two premium seven point five is
used to only food great connected TV system.
I'm going to add that beefy salt software premiums used for direct connected with this system and stand
alone in resources.
So go to resource download the program and start doing what I'm doing now.
I'm going to grid connected TV system Fulford and you can choose the grid connected with small loot
or direct connected with loot and with battery.
I'm going to with grid connected totally fit and you can enter Z type of E C means supply of grid.
I am on two hundred and seventy volt three figures PA factor is one the maximum.
We had no clinic.
Second thing we are going to do is entering the b v module types were doing managed selection and waiting
for
loading.
You can from right here choose any type of company producing beefy banner I'm going with some PA company
right here.
I'm going to choose the model is B or E twenty two one hundred and forty five.
You can find that a sheet of some power this model by choosing this icon.
As you already see in this tab you find any type of companies we are really choosing some part is B
or E twenty two hundred and forty five of the company calls some.
That power rating is two hundred and forty five for the maximum power play in voltage is forty point
five involved and maximum power point current is six point all five.
Empire.
This one is evil so going with this
there are two ways of entering module area.
First type by drawing is a graphical coverage.
Second type by that that data input we want to use exists generator for living king.
While it
so we can use number of BBM modules equal to 45 modules orientation is one hundred and eighty degree
mean go to South said.
Total is about 30 degree you can find from here.
That type of mounting roof Pearl or mounted roof.
We are going to choose multitudes
the degradation of the module because as you see that modules is already mounted onto the roof so as
there is no shading right here sensing we are going to do is the degradation of the module the meaning
of the gradation is the precision of the modules means the power of the modules is going down into an
easier by say for 20 years going to 80 percent of Zumwalt you mean 1 percent for each year now we are
see the the modules going to the next one is selecting Zane vert from this step to select Zain Verjee
you can select any type from right here.
Select
you can add or remove any type of modules from right here
and I'm going to choose the inverter of APB this one and this third calculation
we have different calibration of this methyl first timers is the modules by using surface three hundred
what we are going to use three modules each module is connected in series with 15 module
the second type is 40 hundred What is less calibrated put Xen is the first one because as you see right
here they can be pretty is about 85 percent right here is eighty one percent is going down so is the
best one is the first one this one B V S 300 T.
Thirty three hundred.
What two we are going to use three inverters a chain voter is connected to 15 modules and we already
choose this one each a strength or each inverter is connected to strength and Asia steering is consist
of 15 modules ensues as shown right here seven saying we are going to choose is a type of a cable we
can as Z cable losses from right here directly or by diesels let's say in details we have two types
of cables easy cable and DC cable first list a thought by AC keep their meter is this thing as far from
the inverter let's say twenty five meter we are using cover wire of four millimeters squared.
We are using circuit breaker and residuals comms device what are you using in BBT 1 and is a number
of the ambulance under the tracker is for 3 for each string and 1 common for the count you can add from
here the isolated later 0 are two types of isolated first isolated implemented is the inverter like
this one or so variously from the inverter I'm using says separately 1
we are going now to the second type is a cable that DC cable or string killed let's say we are using
cable connected between Z drink and Z inverter let's say 5 meter of 4 millimeter squared square cover
you can choose one less than for a.
We are going choose 2.5 and we have to choose for this one is six millimeter squared is better than
fourth.
Now we are going to draw as a circuit diagram of this one from this tap as you see you can draw a the
wrong let's say the second diagram ignore waiting this as the circuit diagram of the outburst we are
using three inverters each inverter connected to string it just strength consist of 15 modules in serious
the cable connected between the strengths and the inverter is five meter as a cross section area is
two point five millimeter squared to getting connected between the inverter and the meter is twenty
five meter of Cross section area six millimeters squared.
This is the residual current device.
This one is the circuit breaker.
This one is circuit breaker.
This one is isolated.
You can find inside the right put on that type of the system and z table as a source Z system output
that company and system address created boy approved by port number and the title of this project and
the number of sheep and the issue.
This that is used for financial analysis according to any country has at any kind of fees and financial
analysis.
You can't choose you or financial assets from right here I'm leaving it as it is then we are going to
calculation
from right here you can find that total energy or production for cost is a whole leave into January
and December has the lowest energy in the entire year.
But in May has the highest value is about fifteen hundred kilowatt hour Z total energy in the year is
about eleven thousand three hundred and twenty seven kilowatt hour Z amount of energy beer.
Q What beat is equal to one thousand twenty six point nine kilowatt hour.
B A kilowatt the middle form and c issue is about 88 percent
energy from grid is about 44 kilowatt hour per year.
And ZB system is four point eleven kilowatt hour.
Very you can find the right use it in preacher in the entire year.
The look of is for that I would cite in preacher or Satan preacher for any variant of zero.
Or you can find Z module temperature is the rate curve as you already understood from Z.
Second Section Z Z due to pressure must be greater than the outside temperature dependent on the of
solar radiance and ambient in breach.
Second thing you can find right here is the solar radiance value on the entire year.
This is January and this town has the lowest value of their solar radiance.
But in May and June and July you'll find XYZ value of the Z solar radiance.
The blue curve is used for a radius until horizontal Glenn this curve is used to for a radius onto the
satellite surface.
You can find right here is a performance ratio the performance ratio is going between eighty eight percent
you can find the right here's the beat the system energy balance Z relation between Z input energy and
the losses to give us all good energy.
We have is a little bit.
All right this is one thousand forty two key to what our beer meter squared.
We had division losses from the standard.
Spectrum is about minus ten point forty two kilowatt very meter squared.
You mean that global or ideation as a module must be equal to one thousand one hundred sixty eight point
five kilowatt hour.
It needs a split we are already using for five modules.
Those four to five modules covers an area about fifty six meters squared so fifty six meters squared
times one thousand one hundred sixty eight point five.
Q What our parameters glad will give us suggestive five cells in four hundred fifteen point four kilowatt
hour we have losses according to its DC conversion as the rated efficiency of the modules is about nineteen
point seven percent times as value you can multiply that nineteen point seven percent times this is
very you'll find out that rated b the energy is about twelve thousand eight hundred and eighty three
point seven kilowatt hour we have low light performance losses and division losses from Z no mean then
Module Two pressure and diet losses and mismatch according to manufacturer information and mismatch
do according to shadow because we already leaning on the roof so their schedule mis mesh losses is equal
to zero to sustaining cable or DC cable has losses about minus two point to five kilowatt hour so that
outward energy ought to be v energy DC without inverter is equal to twelve thousand ninety six point
eight kilowatt hour by ending Z maximum power by.
You'll find out z b v energy C without inverter is about twelve thousand eighty two kilowatt hour
after adding to the losses of the inverter such as Z voltage division and DC AC conversion efficiency
as a stand by consumption and easy.
Cable losses you'll find out z z then V energy E C minus this then the boy use is in eleven cells in
two one hundred eighty three kilowatt hour.
By adding Z standard by consumption or forty three point five it you will find out Z great fit n is
eleven thousand three hundred twenty six point seven kilowatt of the last step is for financial analysis
according to your country you can find right here that financial analysis the B vision greater outward
and Z start of Operation and return ends a total investment of course you need and the incoming net
subsides and of course and so on.
You can find the cash flow table for each year first year you had to be Z investment cause they export
trophies give you about one million pound and so on for a second year 30 years for CFC is six year seven
year as on you can find the year the cash flow as you already can see it.
And as for teen year you can find the first proper return of
after 14 years.
You can find the first profit return
the lost 14 year helps you to get Z investment cost so less debt is used to give you that view presentation
to the project mean that that sheet of the project can find right here in the first page Z.
Project name the company client
is a phone and email and contact the better some
ends a project Iris as a start or completion date and project description.
It is a second page you can find that great connected TV system that I was at B V system and the climate
date and DMV visionary to Parliament is about 11 kilo what their peak
their surface area is fifty six meters square.
We are using forty five modules and three number of converts.
This is the same single diagram of our system.
Zale is eleven thousand and hundred twenty seven kilowatt hour.
Barry their performance issue is about 88 percent their total cost investment.
Is this 1 0.
Their this percentage after sixteen point seven years.
You can find that first the profit
second pitch is used for setup of the systems and b v module area and losses and the inverter easy man
supply.
As a kid
you can find right here the simulation results.
Such as the system.
This is the curve of production for cost general area and the sound has the lowest value and the army
has the highest value
you can find.
The idea is that BP Solar energy balance Z total and Billboard said that output both according to several
type of losses you can find the right here's the financial analysis and the cash flow you can find right.
Here's a cash flow table and right here ZBB module is from a company called SunPower solar type is monetarist
the line cell phone number of cells in each module is 22 number of Bibles out in each module.
These three Z dimension of Z modules is one this module is families has no frame.
So I take care of the maximum boilerplate voltage and maximum Burbank grant and a maximum boilerplate
power.
Zelman circuit voltage at all shorted current
under us of that phraseology you can fry anything right here is it as a sheet of the inverter.
It is from a company called ABC as NBC polar rating is three point four is the ABC board rating is three
point three.
The efficiency of this inverter is about three point three over city point for
you can find right here as a nominal DC voltage and the medicine input voltage and Mesa and we'll and
feet and from us on you can find that out right here is their maximum power plant tracker that is sheets
right here lust saying we are going to discuss in this that a sheet is that you can find right here.
The single line diagram
this never showed you can export as PBF or even the more you can find this result in simulation Excel
sheet.
I hope you had the agreed benefit of this course.
I hope you understood new information about V V systems is a Z on grid or standalone b v system.
And understands that devious system component and how to choose every component.
I hope you have fun with us.
Thank you for listening.
And if you had any problems please don't hesitate to ask us any question and we will help you with answer.
Thank you for listening.
See you in the next course.
