We were briefed by Grenzone's Mr Teo
on the basic operations and maintenance
of the Solar Water Fountain.

| Mr Teo explaining to us the various parts of the Solar Water Fountain, such as the control panel, water pump and battery module. | |
Today, we had another training in school by Mr. Teo. We are allowed to skipped our Coach programme as it started at 2.30pm.
ReplyDeleteIt was drizzling, which made me realised that everytime we had our trainings, the weather was bad.
We learned knowledge like introduction to photovoltaic power system and the applications. I did not know that the photovoltaic cells could be used in so many ways. Example, tellecommunications & billboards, water pump, transportation & utilities. The solar cells is also made up of many different layers. Our solar fountain is made up of amorphous silicon and it is a stand-alone PV system. We also learned the factors affecting the solar cells. Example, tilt angle & orientation, shadow, dusts, dirts and fungus.
Our solar cell is sealed properly, so we do not have to woory the fungus growing on them. But WE MUST CLEAN THE WATER PUMP AT LEAST ONCE A MONTH! If not algaes will be growing on it just like the picture Mr. Teo showed us and we will have to change a new water pump.

ReplyDeleteIts raining again! The second day of examining the solar panel and its still raining. Well besides that, we had half an hour of learning the photovoltaic system or PV. Mr. Teo, taught us the factors of the destruction of the panel. There were also some importatnt facts that we need to know. Do you know that solar energy that comes from the Sun provides 1,540 Peta kWh/year?
Well thats not all, some of the solar panels were translucent and many more.
After the lesson, we went out and examined the panel. It was drizling so we had to borrow the school umbrella in order for us not to fall ill. To make it even worse, tomorrow would be my Mother Tongue 'O' Level. ARGH!! Stress!!
When Mr. Teo explained to us about the energy the Sun provides us, Mr. Kumar had fun playing with the solar panel by blocking sunlight from entering the solar panel. Wooh! There was still a child in him. Well Thats all.

ReplyDeleteToday we had another talked by Mr teo about the solar panel. We got a better undestanding on how the solar cell function to operate the water fountain and the ways to maintain the solar panel. we also gain more knowledge on how the use of solar energy can benefit and save the Earth.The Sun actually generate 1540 peta kwh/year which is 15000 more than the electricity comsumed by human, it is actually quite a waste if we did not make full use of the Sun energy. Although it maybe a bit more costly to have the solar cells but it indeed help the Earth to save a lot of resources. It is an interesting talk.
Xin quan's reflection:
ReplyDeleteThis was the second meeting we had together, as well as the second times we do our reflections in our dear school's library.
Starting, we had Mr. Teo to have a theory lesson with us. The talk was mainly about the Photovoltic (PV). Throughout the whole lesson which last for about 30minutes, and it filled us with surprise, some of which was that the Sun actually generate 1 540 000 000 000 000 000 Kwh/year!!!
We had also learned about the Photovoltic cell's efficiency, as well as the types of different Photovoltic cells, which consists of the Monocrystalline Silicon cell, Multicrystalline(Polycrystalline) silicon cells and last but not least, what our school will be using for the solar fountain, Amorphous silicon. We had also learned about the Photovoltic System, and the appliance of
the Photovoltic system. Out of my surprise, what i though that the Solar power system was Solar water heater but this isn't true!!! After our theory lesson, we had a short outdoor activities, and as usual, it was drizzling, in the end, we need the presents of the umbrella from the school.
After all, today's training session was quite a fun and enriching one.

ReplyDeleteSolar fountain Reflection:Talks
Today I learn alot of things about 'SOLAR' as well as'PHOTOVOLTAIC SYSTEM'.
The talk today was conducted by Mr Teo. It last for about half an hour. From the talk, I learned that 'solar' is related to the 'Sun'.
The sun actually generate enormous amount of enrgy.
Solar Power System is not the same as Solar Water Heater. Although they uses solar to generate the power, but their uses are different. Solar Power System actually generate electricity while
Solar Water Heater heats up waterI also learned about Photovoltaic solar cells which convert sunlight into electric energy. The Photovoltaic contains: negative and positive-type silicon that is seperated by a junction layer.
On top of that, i learned that there are different types of PV cells such as Monocrystalline silicon cells,Multicrystalline silicon cells and Amorphous silicon.
I also learned that solar module is made up of single solar cells put together either in series or parallel.
There are several facter that affect the PV performances:-solar insolation
-tilt angle and orientation[must be tilted to about 5-10 degerees]
-temperature
-shadow
-dust,dirt,fungus,birds
-local climate
I also learned that it actually help improve living condition as well as safety and security.
HI ying ying here.
ReplyDeleteWe had another training by Mr Teo today. The training started of with some slides, teaching us about some facts of the fountain. Some are facts, applications and how the whole thing works. I also learnt some types of PV cells, such as monocrystalline Silicon cell, multicrystalline(polycrystalline) cell and amorphous(non-crystalline) cell. Our Solar Fountain uses the Amorphous cell.Some information present in the slides are layers of the PV cells, backsheet, encapsulant, solar cells, encapsulant, glass, then frame. The slides also tells us that shadows, tilt and orientation of panels, Dust,dirt,fungi can affect the output performance of the Fountain. THen is the types of photovoltaic system, components of the system, applications and some types of commonly used systems, such as Solar Home System, Solar streetlight.. After that we had the hands on activity where we learnt how to operate the system and to experiment with the panel. Although there is a slight drizzle, Mr Teo told us that the fountain can still work as the panel can captue the "blue"? light from the sun. We then experimented by covering the panel with the umbrellas and saw the distinct change in height of the water.

ReplyDeleteWe had another training today by our same old 'emcee' , Mr teo , he started with powerpoint slides that shows facts about solar panels. Well , i will give you a question to ponder about... Do you know what's the FIRST GENERATION of solar panels? Clue : Its something hovering around the universe. I will reveal the answer after I done my reflection. Anyway , I'm not going to say all the information that our 'emcee' has gone through as many of here has mentioned and repeating the same thing. After the presentation , we went to examine the solar fountain. Although it is drizzling , Mr. Oliver still gave us WGS umbrella. As the sun was 'hiding' behind the clouds , the water shot up did not even reach any of our heights and Mr. Oliver kept on laughing and joking about it. Afterwards , our very last step is to... Do this reflection ! :D
Oh , I almost forgot , the answer is.... Satellite ! There's no any energy in the universe except for the solar energy , therefore , when you see satellite on TV , there is always two fin-liked structure sticking out by the side. Those are the solar panels :D Great , isn't it? :D
