Generating electricity on house roofs and
developing household-created electricity is a good solution for clean energy,
especially when large solar power projects are having difficulties due to high
investment rates and lack of land. Under Prime Minister’s Decision No 11,
Electricity of Viet Nam (EVN) has the responsibility of buying electricity from
solar power projects at VND2,086 per kwh, or 9.35 cent. Experts, in a
fact-finding trip to Binh Thuan province 2016, found that many households were
still of two minds about installing solar power generation systems on their
roofs. The problem was that if the systems generate more electricity than they
need, they cannot sell the excess electricity. Some households installed
low-capacity systems to avoid waste. However, with the new policy, the systems’
owners will be able to sell electricity to the national grid at prices set by
state management agencies. “If the State applies a reasonable and flexible
policy on buying and selling electricity, people will develop large-scale
electricity generation systems,” said Vu Hai from Binh Thuan province who has a
VND140 million solar power system. Surveys all found great potential of
developing solar power on roofs in Viet Nam. In Ho Chi Minh City alone, there
are at least 300,000 house roofs on which solar panels can be set up to
generate electricity. If two solar panels are set up on every roof, the city
will have the total solar power capacity of 78 MW, or 105 million kwh, equal to
the output of the Can Don Hydropower Plant in Binh Phuoc province. One
household just needs to install the system to generate 4-5 kwh a day which can
provide power for four fluorescent bulbs, four fans and one TV. However, Hoang
Tien Dung, Head of the Energy Institute under the Ministry of Industry and
Trade, warned that while it is technologically easy to generate electricity on
roofs, it is still difficult to set up the pricing policy. Estimates show that
solar electricity on the roofs need to be sold at 12-13 cent per kwh to make
profit. Solar energy getting cheaper Dang Dinh Thong from the Viet Nam Clean
Energy Association said that the lower investment rate, plus the higher
electricity price fixed by the government, will help encourage the development
of solar power in Viet Nam. “Ten years ago, the investment rate was USD6,000-7,000
per KWp, but the rate is only USD1,000 now,” he said. As for the new
electricity price set by the government, Diep Bao Canh, CEO of Red Sun, said
9.35 cents per kwh can ensure moderate profit, but investors’ expected price is
over 10 cents.
