Arosa Solar Energy Demonstration Lakewood Cheder

it is a little bit dark in here why don't we get the lights off before we start beautiful did someone just tell me what just happened with these light switches over here and then when we turned on this way it's your parents that now get an extra bill an electric bill that they have to be paying for but it's no problem how do you pay it but the bottom line is this waste is circumvent that this shouldn't cost so much money it's making its way back to countries that are producing oil and this is all something that we really if we want to be part of a independent all independent on our own and not being dependent on other countries our correct way is to try to figure out a way that when we do flip the light switch there was no extra there was no electricity use that we have to pay for that we have to pay other people for how do we go about doing that hashem created by a glorious world part of the glorious world that he created was the sun everyone knows every single morning the sun goes up every single night the sun goes down has that ever stopped in history yes yes how many times that's right twice it's tough on it twice and but since then as we all know it's something that happens every single day and is expected now we can take a solar panel like this this solar panel is made in such a way that when the sun hits it it produces energy it produces electricity i'm going to have to give a very special welcome to my very good old friend of mine we used to produce a different type of energy together yes so anyways as the song comes down and it's the it hits very hard to describe the exact answer of how exactly it produces it it's a very very uh highly technical method of what it does but it definitely produces regular electricity just like you would use at all now just to prove that everyone got a picture over here of some funny type of plane floating around that's not really a plane that is the the solar that is the space station the the national and that the international space station that everyone knows about now how does the international space station where do they get their electricity from if you look closely at the picture on both sides you will see that there are solar panels coming all over the place there wherever there's an extra place they're stuck in solar panels so when that solar and then when that space station is orbiting around the earth it's picking up all its electricity from the sun the sun is always bright out there it's always picking up we have another solar panel going around you can feel what it is what a solar panel that is a real solar panel you would put that into the sun and plug it in it would produce electricity as you can see over here here the panel looks so extra large over here however in real life if you'll take a look at this picture it's a small little thing sitting up on the roof it doesn't bother anybody and it's producing what's known as clean energy when we using oil oil is something that burns up it creates a certain smell it creates a madness in the air a certain pollution in the air correct same thing when you're burning coal coal produce it produces terrible pollution in the air this is what's known as clean energy and that's the main reason why it's being pushed along so hard by the governments by the state government by the by the federal government only because it's producing clean energy now where do you put this panel everyone over here knows where does the sun come up from everyone else very good where is the sun set very good which side of from east to west does it pass on the southern side or on the northern side very good these guys know their stuff so if we have the sun coming up on the east side over here sun is standing on the west side over here the sun is passing throughout the southern side all along what we always want to do is make sure that these panels are having a southern orientation that are tilted towards the south to pick up as much of the sun as possible throughout the day every so often we if you'll take a look at nina's dinette the picture his building is facing perfectly south when we put those panels up when we put those panels up as soon as as soon as the sun started coming up it hits that those panels right away and it's basically there for most of the day unless certain parts of the summer now does everyone know that the sun goes up and down different ways in the winter and in the summer i mean how many of you are for watching in the winter the sun is always going to be much lower than what it's going to be in the summer the sun is always going to be much higher up and therefore going to give a much stronger impact on the panels therefore producing much more electricity just for another short little thing just to know that the state of new jersey and the federal government of the united states is really really interested in solar energy therefore they provide a lot of incentives and a lot of rebates for people to go out there and buy themselves any system you put up typically 55 about 55 of the system is already paid for before you finish putting it up between the state of new jersey and the federal government so really today it's not even such an expensive thing to go in there and put that solar energy and in the long run it ends up saving people a lot a lot of money any questions about anybody some of my students actually had a few questions first of all let's say i'm doing snowing if it would snow on the panel then it would not work for those few hours of days that the pan was thrown up what's important to know is that whenever it's snowing whenever you put in solar let's forget about snow what happens if it's raining or what happens it turns night every night so polar energy actually only produces one of the substrates there are certain systems where you can take the sun and you where you take the solar energy that's produced and store it in batteries and then use it throughout the night most systems that are produced do not work that way most systems work only when the sun is shining and the rest of the time you have to be lying on the regular adjacency and now whatever your uh another question they have is so let's say we have a very hot with a very sunny week how long will that score uh for the clarity this one well again most systems do not work with scoring what happens is if you're producing energy and you're producing more energy than what you really happen to need in such a case the the extra the excess energy will be sent back to jcptnl and they will buy that energy off you and therefore you'll have a credit on your electrical bill which you will use up at night times unless they're doing real hot summer days the air conditioning is blasting away and you're using too much energy and you can't provide it anything else now how do we know how much shading is going to be producing how much shading there isn't is it really a problem maybe only in the summer and maybe only in the winter and after the summer we have this camera over here if you pull the camera we can actually try to take some type of picture with it and just to give you an idea this is called a solomatic for the video uh you can pick up which area you are in so we're going to pick more branches in jersey as the area that we're in um it looks like a gps yes guys there's really not much you can see from over here but this is what i'll show you something very interesting in a moment oh it may take about 20 minutes now very important when you take this picture is the camera has to be longed on towards sound all right everyone with the compass on it just stand right okay this just took a picture he was on the side of the picture as everybody saw and if you take a look at the picture see myself there you go this camera i'm going to take it around the choke very quickly if okay yeah yeah the point is that this is a camera that takes pictures not just of what street in front of it or what's right on top of it it really goes around to all the sides of the thing and therefore you could really is um oh
