School self
Recently, Jinan secondary investment of 1.2 million, in the school self-built a small solar power station, which primary and secondary schools in Jinan City, the first time on campus. However, the station can only send more than ten units of electricity a day, from the perspective of input-output operator, 20 years to recover the costs. In this regard, it was felt, as a secondary school, not cost-effective to spend money to build such a facility, there is this necessary? However, teachers and students but does not think so, the students of the school with solar power stations are very proud of the teachers think that students who contribute to environmental awareness and scientific spirit.
Students were very proud of, "We can use solar power school friends!"
13 afternoon, held in Jinan secondary grid solar power station official ceremony, after the power station has been test run a few days, and has made more than 100 kWh. Teaching building's roof in the school to see this solar power plant, which is mainly from the 12 high-purity crystalline silicon plate (pictured) and an inverter component.
"Our school can use solar power it!" The school's students build solar power plants on the school all felt very proud of their working principle of solar power generation is very familiar, the students, said to reporters, the crystalline silicon board to receive sunlight, the voltage difference will have to output current. Because the resulting direct current, they must go through an inverter, these DC into AC, stabilized at 220 volts, so that can be incorporated into the school network, to supply a normal school.
Many people question the "input 120 000, 20 years to recover the cost, not worth"
However, the reporter learned that this sets the price of solar power equipment is not cheap, in charge of the project, Vice President of Jinan School, said Yang changzhai for building the small solar power plants, schools invested 12 million, mainly because solar power is the main raw materials of high purity crystalline silicon, crystalline silicon purification costs are very high, and inverters are not cheap, but this solar power station, once completed, the performance is very stable and can run at least 30 years.
Then the solar power station can send the number of units of electricity a day do? Professor Yang said that from the point of generation cost, the solar facility is clearly not worth the current average of the power station can send a dozen of electricity a day, doing we can send 3,600 kWh a year, while last year all schools in electricity 940 000 degrees such calculations, solar power generating capacity of only 0.4% of the school can be said to drop in the bucket.
Professor Yang said, because of cost, for this project, many people have put forward different views, for example, many schools will put their money into planting trees on campus, or in the teaching building Shop beautiful brick wall paintings, as do such things will soon see the results. This time the school put so much money to buy back a few crystal plates can be made more than ten units of electricity a day, the need for so many years to recover the cost, if this is some not worth it?
School think so, "in practice to improve student awareness of environmental protection"
Jinan Environmental Protection Bureau of Environmental Protection as a volunteer, Jinan School Vice President Yang changzhai clear that he believes that in the school garden, spend money building a green project, a very exemplary. Because the national primary and secondary school students in the promotion of energy conservation, but often talking a lot, but little has been done specifically. The school is to invest in solar energy power stations make the students feel the genuineness of the new
Energy Environmental effects and principle, in practice, to improve the environmental awareness of students.
According to Professor Yang introduced solar power station set up in schools, primary and secondary schools in Jinan city in the first case of its kind. Primary and secondary schools in the current daily classroom teaching, many subjects will be referred to the knowledge of new energy sources, but are often on paper, but now schools are able to see for themselves how solar power is how to save energy so that what students really understand what it is "low-carbon life", and thus the growth of students is very helpful.
