APPLICATIONS OF SOLAR ENERGY IN VIETNAMTwo main applications:- Solar hot water- S

11、olar photovoltaics2.1. SOLAR HOT WATERSolar hot water has been developed since 1990. At the early period, it was very difficult to get the attention of the community.But, since around 1998, the number of installed solar hot water systems has gradually increased, especially in Ho Chi Minh city.Curren

12、tly, solar hot water has become one of products at high competition. That leads to the increase of the number of companies doing business in this field.But, there is so far no full industry referring to solar hot water. The main components of the system (solar collector,) are imported, mainly from C

13、hina. COMMENTSolar hot water has been developed very fast, especially in the southern parts of the country. Currently, it is easy to see solar hot water systems on roofs of many houses in Ho Chi Minh city.2.2. SOLAR PHOTOVOLTAICS2.2.1. RESEARCHResearches referring to solar photovoltaics have been do

18、activities of scientists in laboratory only. It has not exercised its influence on the society.2.2.2. APPLICATIONSIn 1990, the first 300Wp-unit was installed at Can Gio district, Ho Chi Minh city.From 1994, solar photovoltaics has been expanded in the whole country.Currently, total installed photovo

19、ltaics is around 2MWp. Installed locations:- Rural areas (PV units were installed at more than 3000 houses, there have been around 8500 families who can reach PV indirectly by using batteries charged from stations).- Cultural centers.- Medical centers.- Telecommunication units.- Traveling boats.- Po

20、st offices- Ambulances.- Public lighting systems.- Traffic lighting systems.- Battery charging stations. - Schools.- Islands.2000Wp810WpMain features of photovoltaic development in Vietnam:- Most budgets funded by international organizations and several funded by national agencies (there is so far n

21、early no personal budget invested to set up the system).- It leads to unstable and unsustainable development.- All solar panels are so far imported.Currently, there are only several companies doing business on photovoltaics in Vietnam.Recently, a factory producing solar panels has been installed in

22、Long An near Ho Chi Minh City. By planning, its expected capacity is 3MWp/year (first step) and 5MWp/year (next step).COMMENTSolar photovoltaics has been almost done by projects and has been installed dispersedly. There have been only a few people who want to invest the photovoltaic system by their

23、own budget.2.3. OTHER APPLICATIONSSolar Refrigeration and Air ConditioningSolar DryingSolar CookingSolar DistillationMain features of these applications:- Not popular- Research phase- Low attraction of the community3.

24、nergy and on applications of solar energy3.2. EXPECTED OUTPUTSDegree of training programsMasterPh. D.Research activitiesMainly in:Solar photovoltaicsSolar refrigeration and air conditioningSolar distillationOther applications in connection with solar energy.3.3. BASIC IDEASStudents: mainly coming fr

25、om Vietnam, but it is expected that the school can get the attention of students coming from other ASEAN countries.Language: EnglishTeaching staff and supervisors: mainly coming from Vietnam and from the USA, some selected professors from other ASEAN countries can be invited.Tuition fee:In order to

26、speed up the application of solar energy and to get the attention of students, the school should be one of the objects supported by the governments.Therefore, students pay a part of the fee only, the partners cover all the remains.Training form:Master: full time in VietnamPh.
