Abstract
Vietnam is considered a country with huge potential for solar energy, especially in the central and southern regions of the country, with an average solar radiation intensity of about 5 kWh / m2. Meanwhile, solar radiation intensity is lower in the Northern regions, estimated at 4 kWh / m2 due to weather conditions with cloudy sky and drizzle in winter and spring. In Vietnam, the average solar radiation of 150 kcal / m2 accounts for about 2,000 - 5,000 hours per year, with a theoretical potential estimate of about 43.9 billion TOE. Solar energy in Vietnam is available year-round, quite stable and widely distributed in different regions of the country. In particular, the average number of sunny days in the provinces of the central and southern regions is about 300 days / year. Solar energy can be harnessed for two uses: electricity generation and heat supply. There are four types of solar technology currently available in Vietnam market. These are household-scale, commercial-scale solar technologies used for hotels, restaurants, hospitals, military and service centers, for villages such as public lighting and sound., TVs and charging stations. In Vietnam, photovoltaic panels (Photo-voltaic: PV) are imported while other components of the system are domestically produced. Vietnam Posts and Telecommunications Group (VNPT) and Vietnam Electricity (EVN) own member companies that design and install solar power systems for internal use.
