Both: Hi Guys! Kimroy: Welcome back to another video in our
educational series: Step by Step Solar A series dedicated to teaching you how to
make money from the solar industry In this episode guys I will be doing an overview
of all the components in a solar system Mrs. Bailey is very green to renewable energy. She knows little or nothing just like many
of our viewers. So she is going to ask questions and I am
going to question her and you as well. Kimroy: So, what is the heartbeat of a solar
system Mrs. Bailey? Kimroy: NO! Its actually the solar panel. Mrs. Bailey: Solar Panels
Kimroy: Solar panels are the heartbeat of the solar system. The real name for these are photovoltaic panels. That is how we generate voltage from photons
in the sun rays. That is why shadowing is very important and
ensure that the solar panels are currectly positioned. Later in the series we will be doing a video
series dedicated to solar panels. In those videos we will talk about the angle
of the solar panels, the sun rays, the equator and all that good stuff. Kimroy: So now, let us go in further details
into our solar system. The sun light hits the solar panel. The solar panel has wires at the back, like
this. Finally, the solar panel is actually connected to a circuit breaker. Kimroy: Why do we connect our solar panels
to a breaker Mrs. Bailey? Do you have any idea whatsoever? Mrs. Bailey: Circuit breakers control the
electricity and the flow of electricity Kimroy: very good. Mrs. Bailey: or it stops the flow of electricity. Kimroy: Yes. It can stop it by turning the circuit breaker
on and off. Good! Connecting the solar panel to a breaker like
MRs. Bailey said allows me to stop the flow of electricity. Take a look at this guys! The power comes here and is connected to a
breaker. From the breaker we then go to the charge
controller. Do you have any idea what is a charge controller
Mrs. Bailey? MRs. Bailey: Yeah! A charge controller… uhmm… No, no I don’t know what a charge controller
is. Kimroy: She does not know what a charge controller
is. Well she tried
Kimroy: What does the word charge imply? Mrs. Bailey: Electricity! Kimroy: Yes. Have you ever charge your cell phone before? Mrs. Bailey: Yes! Kimroy: What do you do when you charge your
phone? Mrs. Bailey: I plug in the charge to the cell
phone Kimroy: And what does it do? MRs. Bailey: when it is fully charged I take
it out Kimroy: What what is fully charged? MRs. Bailey: The battery! Kimroy: Wow! (Applause) You used the word battery! Therefore, the charge controller helps in
charging the…? Mrs. Bailey: Battery
Kimroy: Well, great! So from the solar panels to the …..?
Mrs. Bailey: circuit breaker Kimroy: from the circuit breaker to the …. ?
Mrs. Bailey: charge controller Kimroy: and from the charge controller to
the … ? Mrs. Bailey: Batteries
Kimroy: Great! That is very good. Mrs. Bailey: So let’s overview from the
solar panel to the breaker, then to the charge controller and then to the batteries. Kimroy: That is great! So the whole point of collecting the energy
from the sun is to enable us to charge our batteries. And why would we want to charge our batteries
MRs. Bailey? Mrs. Bailey: Well charging the batteries, that much I know! The battery stores the energy. Kimroy: Very good. And what time do most home owners go to work
in the mornings? Mrs. Bailey: From about 9:00am to 5:00 pm. Kimroy: Good. And about what time do they return home? Mrs. Bailey: at about 6:00pm. Kimroy: and where is the sun at 6:00pm? Mrs. Bailey: There is no sun at 6:00pm
Kimroy: There is no sunshine at 6:00pm What happens therefore is that most of the
energy is actually used by the home owner when the sun is
Both: Down Kimroy: Very good. And that is why the battery is the heartbeat
of all Off Grid solar systems. because it allows home owners, once they come home They want to turn on the TV, they use the
microwave, they also turn on the lights. At that time they are using energy from the
batteries. Mrs. Bailey: Batteries
Kimroy: The energy then leaves from the batteries and goes to another? Mrs. Bailey: Circuit breaker
Kimroy: Very good! And from that circuit breaker we go to the
…? Mrs. Bailey: That is the inverter. Kimroy: Any idea what the inverter does? Mrs. Bailey: Awhh it transforms the electricity
form DC to AC Kimroy: Wow good answer! Mrs. Bailey: Ok guys, Guys it said that on
the thing (inverter), from DC to AC Kimroy: Let’s talk a little about DC and AC DC stands for direct current. Direct current is generated by the solar panel and stored in the batteries. But when you plug your cell phone to the wall outlet at home you receive alternating current Hence we need a component that transfers from Direct current (DC) to AC Alternating current (AC) and that component is the Inverter. Kimroy: So the Inverter basically, all it does is it powers your home by converting DC energy into AC energy. Whats AC enrgy Mrs. Bailey? Mrs. Bailey: Alternating current
Kimroy: and whats DC energy? Mrs. Bailey: Direct Current Kimroy: Let’s do a quick breakdown again.. Both: From solar panel to beaker, from breaker to charge controller, from charge controller to batteries
From battery to Inverter Kimroy: Something comes before leaving from the battery to the Inverter Mrs. Bailey: What’s this thing? (points at a wind turbine charge controller) Kimroy: Ah great this is another charge controller for a wind turbine and in our next video we are going to be assembling a demonstration wind turbine for you to understand the the principles of wind turbine technology and how it works Mrs. Bailey: What step did I miss from the
battery to the inverter? Kimroy: Actually between the battery and the Inverter is another breaker Mrs. Bailey: Ahhh!!!! Kimroy: Alright so let us take it from the
top Mrs. Bailey: From the solar panel to the breaker,
then from the breaker to the charge controller, from the charge controller to the batteries,
from batteries to breaker and from breaker to the Inverter
Kimroy: Very good , very good. Alright let’s look at this (the labels on the
breaker box). (Each circuit breaker has a label, it says)
Charge controller, Solar Panel and Inverter. Kimroy: So what this does quickly solar panel
to a circuit breaker. This protects the charge controller from the
power coming in from the solar panel if we want to turn off that breaker. Therefore we leave from the solar panel to
the charge controller breaker. We then go to another breaker from the charge
controller and then to the battery. Finally we go to another breaker from the
battery and then to the inverter. Here we have two things on the side, I will
not ask because Mrs. Bailey does not know what they are. These are actually called surge protectors. And that I will ask her! MRs. Bailey what do you think a surge protector
is used to do. Mrs. Bailey: Well the surge protectors that
I know are the ones that you plug your laptops in For example if there is a lightening strike
the surge protector protects your laptop. But I have never seen a surge protector looking like two cylindrical items before. Kimroy: So these use the very same principle. This is a direct current or a DC surge protector while this is a AC (alternating current) surge protector From the solar panels if there should be any
lightening strike or any surge or any short circuit This (DC surge protector) will essentially self destruct to protect the other components in the circuit. The same principle applies on the AC side. The alternating current comes from our inverter so if there is any thing wrong on the grid or any feedback electricity from the appliances this
surge protector will self-destruct to protect the appliances in the circuit. That is what our surge protector is used to
do. Kimroy: And guest what? Voila! That is the overview of our system. So can you do a quick recap for us Mrs. Bailey? Mrs. Bailey: I believe Ican! Kimroy: Great
Mrs. Bailey: So it is from your solar panel to your breaker then to your charge controller
and from your charge controller to your battery and from your battery to another circuit breaker
and from that circuit breaker to the inverter. Mrs. Bailey: The inverter converts the direct
current to the AC current. Kimroy: Very Good
Mrs. Bailey: What is the AC current again? Kimroy: Al….. Mrs. Bailey: Alternating current? Kimroy: Very good! It is Alternating Current. Mrs. Bailey: And I also learned about the
surge protectors which will self destruct to protect the rest of the system. Kimroy: And can you tell me what the charge
controller is used to do? Mrs. Bailey: Yeah! The Charge controller is used protect the
batteries. Kimroy: Yes! The charge controller helps to charge the
batteries and when they are fully charge it protects them by not allowing them to over
charge. Very very very GOOD! Kimroy: She did a good job, didn’t she? OK Guys check out the course material below
this video. Go ahead and complete our quick quiz and be sure to read the supplementary material to learn all about the different components There are different types of solar systems
such as the grid tied and the off grid system which we also looked at. There are also larger inverters, different
charge controllers. But this video only provides a quick run through of a typical solar system. Thank you so much for watching. Do subscribe to our YouTube Channel. And finally check out the course material
