Solar power will grow when markets
According to the experts, together with wind power and solar energy are two of the renewable energy sources viable and has great potential for exploitation and development of Vietnam. Survey data in the calculation of the meteorological sector showed the intensity of solar radiation in the daily average in the northern region is 3.69 kWh / m2 and in the south is 5.9 kWh / m2. Calculate the national average, the solar radiation varies between 3,8- 5,2 kWh / m2 / day. Average annual number of sunny hours is 1,600 hours north and south is 2,700 hours.South Central and sunny almost all year round, radiant heat stable, very consistent and favorable for the development of solar power.
These years, the Government has invested interest in research utilization of renewable energy sources, including solar power. However, the achievements made so far is just the first step of applying innovative optical technologies to supply electricity and heat to heat rays serve the needs of economic development - social. Currently, the country has only about 2.5 MWp exploited, mainly the solar panels installed on the roof of the building, the telecommunications base stations, the national security agency , transport in remote areas and islands no national grid.
Play solar power grid was also applied research in our country since 2005; Solar power works best in fighting large net capacity of 154 kWp at the National Convention Center in Hanoi. In addition, may include net play two electricity projects typically project-grid solar power in buildings Ministry of Industry and Commerce (capacity of 12 kWp) and at the Institute of Science and Technology of Vietnam with a total capacity of 6 , 7 kWp by the Institute of Energy made.Most recently, the Ho Chi Minh City Party Committee has invested in installing solar systems play 11.4 kWp grid capacity at the headquarters of the City Party Committee.
With these figures the actual exploitation mentioned above, compared to the technical potential is calculated, the solar power in our country is still in the form of potential, the pilot and a number of small applications. Vietnam has not yet formed the solar market. The mechanisms and policies to support not make investors indifferent to the field is quite new to this. Moreover, technology, human resource development of solar power is very limited. Meanwhile, the technical potential for solar power generation grid football focus of Vietnam estimated potential 1.799MW and installation of solar systems locally / family are 300,000 homes, equivalent to the capacity of 20MW.
Currently, the application of solar energy in the world and in our country even more difficult due to equipment cost solar technology is still too high. Solar power is still the most expensive electricity in the renewable energy source. Taking an independent station not play through, cost about 5- 6 USD 1Wp. According to Dr. Duong Duy Hoat, industrialized countries and markets solar power development are the countries with the right development policies, strong legal system and mechanism for support, especially support State subsidies.
To be able to fully exploit the potential of renewable energy sources of this valuable, Dr. Duong Duy activity that the current point is the need to generate solar power market, under the policy support system The Government's comprehensive. When there is a market, there will be immediate link businesses with scientists bring technology and investment capital. And with half-hearted support mechanism with a weak policy framework at present, it is difficult to develop electricity from renewable energy sources.
Thus, the State's role in building the support infrastructure to form the solar market is extremely important. To get reasonable support mechanism, sufficient market formation, should have advocated proper orientation on the basis of a law on renewable energy. In the immediate future, the law has not yet built up the research and provide a mechanism to support prices how to market can generate.These tasks should be based on the scientists to calculate appropriate and feasible, on the basis of absorbing international matching Vietnam context.
Along with that, the training of human resources for the development of renewable energy, including solar power should also soon deploy. In scientific research - technology, Dr. Duong Duy activity that should focus on applications, legacy international achievement, rather than to study again. In particular, it should choose the imported technological equipment suitable for the climate and environment in order to ensure longevity and operability of the equipment, to avoid deterioration and equipment failure as the the project has been implemented recently.
Many countries have been investing heavily in research and development, technology should use solar energy perfecting increasingly diverse, increasingly lower cost, the range widening application. Solar market growth annually from 50-60% with output in 2012 is estimated at 30GW. If solar power market is formed, this will be one of the key solutions to meet energy demand while increasing fossil energy resources are running out of our country.
