Sustainable Energy in School- Solar Power |

As I?ve written in my previous report, my friends and I did some research on sustainable energy development within our school facility. In this article, I would like to focus on solar power. There were two types of solar energy generation in our school: Solar heat and sunlight. Out of these two, we did an extensive research on electricity generation based on sunlight. What we worked on was the relationship between weather and the actual amount of electricity generated from sunlight. We gathered daily, monthly, and yearly data from the generator, and did a couple of analysis using data programs. The result was close to what we expected in the first place, but we were able to discover some surprising facts. First of all, sunlight generation did not have any positive relationship with the temperature. In fact, it was just the opposite. While most of us believe that solar energy generation would be much more active in the summer than any other season, it is actually the lowest. Although this is the case of Korea, and the results may vary from reason to reason depending on the climate, it came as a big shock. We later concluded that the results were related to Korea?s rainy season in the summer. Although we expect summer with most sunlight, it had the least because of the cloudy atmosphere. Second, the research showed that solar energy production had a startlingly similar relationship with the energy use in our school. The energy use in our school was highest in December and March, as seen in the graph below. The interesting fact was that solar energy generation also had a similar graph, with the generation rate at its peak in March and October. This series of research in our school taught us that renewable energy can be approached quite easily, and also produces a relatively large amount of electricity than what we usually believe. Although it is true that the installation of sustainable energy generators can be costly, it is also true that sustainable energy can be much more effiecient and even economic than fossil fuels in the long term. 1.

@Konstantinos, the playground is behind the school building, as you have guessed!

Surprised to see the sunlight energy generation lowest during summer but as you said the result may vary according to the region. Very glad to see sustainable energy used in your school and you involved in the research regarding it. Keep researching, keep posting :)

Well article,Thanks for sharing interesting report.

@Konstantinos, I guess they have a gym on the top floor of the building since there's no place for the playgound because they're located in the middle of the urban area. Am I right? @Jyeonghyun? :)

OH MY GOD! This is a completely useful article. (for me) Thanks for posting it. If you didnt post it, I would have been blind about this forever. I agree with Wulan, I also hope schools in Indonesia have solar power. It can save the fee to pay for the electricity ehehe.

Well written, Lee. We are surprised by the results for your studies. With passage of time the cost of sustainable energy will definitely come down. Then the usage will be effective.

It's very surprising to note that your research showed that solar energy generation is not directly proportional to temperature unlike we usually believe. It is true that unfortunately renewable energy deployment is very costly still that's why it is not picking up.Thanks for sharing interesting report, Lee.

Very interesting article Lee. Your analysis proves facts beyond intuitive human consideration.
Also I am impressed from your beautiful school in your picture. A question: Where is the school yard? Is it inside the building or behind it, we cannot see it in the picture? How many students more or less has the school? Is it a typical high school in your town? Is it Public or Private?
I hope not many questions :)

Nice article. It is great that your school has solar power. I hope many schools in Bali would have solar power by early 2016. You said that highest energy usage is commonly in December and March, is that due to cold weather?
