Vietnamese households are going green with the help of solar energy. The government has a plan to increase the percentage of households using solar-powered applications from 4.3% in 2015 to 12% by 2020 and 36% by 2030.
\nThe applications include 2 main categories: thermal application and electrical application.

<\/p>\n
Thermal application primarily goes under the form of solar water heater (SWH).<\/p>\n
This is the most developed branch of domestic solar use in Vietnam, as reportedly around 100,000 sets are installed all over the country per year, 30 \u2013 40% of which are located in Ho Chi Minh City.<\/p>\n
Vietnamese households\u2019 typical SWH have their capacity ranging from 180 liters to 360 liters, and their prices ranging from 300 to 600 USD. “Net-Metering Mechanism is the key “<\/strong><\/p>\n Rural areas, where public power grids have yet to reach or outages occur frequently, seem to be favorable locations for SHS. Since most rural households may find initial investment for SHS too expensive, financial assistance from the government and various development agencies (USAID, World Vision Vietnam, etc.), is frequently found.<\/p>\n As for gridded PV system, residential PV rooftop is the one to look out for. Basically, this system allows households to both self-consume the generated electricity and transfer the surplus amount to the public grid, hence the name \u2018gridded\u2019.<\/p>\n Right now, residential PV rooftop is in its early inception stage, as the idea has become relatively familiar but actual utilization is still quite limited.<\/p>\n However, people\u2019s usage of PV rooftop may climb up fast in the future, when net-metering mechanism is put into practice. “Shortage of relevant legal framework”<\/strong><\/p>\n Despite all the potentials and room for growth as explained above, there are still challenges laying in the way. In conclusion, Vietnam\u2019s solar energy market is more suitable for investors who have long term plans, at least until 2030 \u2013 the year at which Vietnam\u2019s government believe solar energy market will reach its maturity .

\n“5000 SHS installed nationwide”<\/strong><\/p>\n
\nSome well-known brands include \u2018Dai Thanh\u2019 of Dai Thanh Group, \u2018Kairos\u2019 of Ariston Thermo Vietnam, and \u2018Sunny\u2019 of Suntech Power.
\nThe Government has strongly promoted SWH usage. There is an active subsidy program in which Vietnam Electricity (EVN) sponsors 1 million VND (app. 45 USD) for each purchase of residential SWH. With such support, it is expected that by 2030 there will be 22 million m2<\/sup> of solar thermal collector area[i]<\/a> in Vietnam (rising from 3 million m2<\/sup> in 2015)
\nElectrical application consists of \u201coff-grid\u201d and \u201cgridded\u201d photovoltaics (PV)[ii]<\/a> systems.
\nThe residential off-grid PV system is commonly known as Solar Home System (SHS). Vietnam had about 5,000 SHS installed nationwide by the end of 2014. An average SHS (160-320Wp), whose main components are solar panel, charge controller, battery pack, and power inverter, would cost around 600 – 1,200 USD.<\/p>\n
\nThe mechanism deducts the amount of electricity a household adds to the grid from the amount it takes from the grid. As such, that household would only be billed for its \u2018net\u2019 electricity used.
\nMentioned the National Renewable Energy Development Strategy in 2015, the formulation of net-metering policy is already in progress.<\/p>\n
\nThe biggest problem is shortage of relevant legal framework. Currently, there are no performance standard, equipment certification, or code of practice for solar energy related quality control.
\nBesides, governmental incentive policies for residential usage of solar energy is quite underdeveloped, mostly as just one-off subsidy on purchase.<\/p>\n
\nIt can also be suggested that Ho Chi Minh City is the favorable location to start off solar energy business, as sunlight there is remarkably abundant and stable, while the people also have relatively high income.<\/p>\n\n
\n[ii]<\/a> Photovoltaics (PV) involves technology that converts light into electricity.
\nOff-grid PV is a system that creates electricity only for household\u2019s self-consumption, without being connected to the public power grid (thus \u2018off-grid\u2019).
\nMeanwhile, Gridded PV system, as it is connected to the public power grid, allows households to contribute its surplus generated electricity to the public system.<\/p>\n","protected":false},"excerpt":{"rendered":"
