Vietnam is advantageous to take advantage of solar power in the range allocated for sunshine most of the year on the solar radiation map the world. However, the utilization of this energy source is still limited.

Water heater: decreased more than 50%
No need to waste electricity and gas costs to heat water, just buy a hot water heater solar installation on the roof of the hot water can be used safely for over 10 years. Benefits are so many water heater manufacturer solar still "charcoal sky" because of unsold products.
Discussions with VNA weekend, Carving Ming Chu, director of engineering Co., Ltd. Manufacturing - Trade - Services Khang Phu Lac, lamented: "Consumption of water heaters on the market a few years ago quite well, but about two years ago, though very slow even though the company has a policy for customer promotion. A 250 liter hot water tank type prior sale price of 8.5 million, has dropped more than 30% but still slow to sell. "
The monthly production capacity of the company reaches 300-500 Khang Phu Lac water heater solar energy, but in the last three years, a monthly average of 100 per sale yet, has sold only 20-30 per month .
"The difficulty we have to try very tense, low prices to the lowest level possible to keep the brand. Companies are doing more work on the glass screen printing to maintain jobs for workers under dozens of companies doing business long since, instead of producing its own hot water heater is not live! ".
According to Mr. Minh, Ho Chi Minh City has about 10 water heater manufacturer solar and other manufacturers who have fallen on tough consumer products.
Overall, sales of many manufacturers declined more than 50% over the previous few years. This was partly due to the number of new buildings less, other parts are still so many people are new water heater using solar energy.
He has said through customer contact, he found that many people still vague about the utilization of solar energy. Meanwhile, representatives of a manufacturer calculate the average efficiency of solar hot water: an average household uses 60 gallons of water per day heated to 60 degrees Celsius, then it takes 4-5 kWh of electricity; if the water heater using solar energy instead of electricity is just over two years is ... breakeven.
Several years ago, Khang Phu Lac is a business in the Ministry of Industry and Trade and the Vietnam Electricity Group (EVN) is selected manufacturers participating in the program to encourage people to use water heater solar energy. Under the program, each household will be supporting 1 million to install a hot water heater solar energy. But despite the support, the number of registered households still very low. EVN said promotions using the hot water heater solar in 2011-2015 (5 years) also aims to average 30,000, of which 5,000 average allocation of Ho Chi Minh City, Hanoi 4000 average, Central 5000 average ...
There is another fact that people have to use hot water heater solar energy is dominated by cheap imports, particularly from China, were sold on the market is widespread. According to the Energy Conservation Center of HCMC (ECC HCMC), HCMC currently has approximately 100 manufacturers and importers average solar hot water. Some imported products after the sale is complete, the "disappeared" to dodge stitching warranty, maintenance for customers in the future.
Vo Dong Thuc, Director of DONG Energy Joint Stock Company - specialized equipment imported water heater solar energy from Australia and China, said a few years ago, each month the company sold average 300-400 but today, the figure has more than halved.
Panels: lack of policy support
Another product also encountered similar difficulties, such as solar panels.
The biggest barrier to the development of this product in Vietnam is high production costs due to raw materials depends heavily on imports. According to Diep Bao Canh, Director of the Solar Energy shares (Red Sun Energy), tax policy was not reasonably should not encourage domestic production. For example, the import duty solar panels finished products is 0%, but some material is produced with 3-15% import tax.
Some other barriers given him wings to explain why solar energy development in Vietnam, not the State is so far not yet written permission grid connected solar power, no major of clearing (or buy back electricity from solar energy), there is no policy on the purchase price for grid-connected solar power ...
According to Mr. Wing, in two years, markets solar panels in Vietnam has increased significantly, mainly public works funded state and localities without electricity grid, street lights, electricity for agriculture ... But despite the increase, the market compared to previous solar battery in Vietnam is still very small, only 1 / 10,000 of the world.
Meanwhile, according to calculations by energy experts, to generate 1 kWh of electricity must use 8 square meters of solar panels for about $ 12,000 US dollars, n
