Vietnam is a country with huge potential for developing solar power. However, in reality, the development of this power source is still limited. According to the data of the electricity industry, the average solar radiation intensity in Vietnam is quite high, about 5kW/ m2/ day and the number of sunny hours is about 1700 - 2500 hours/ year. However, in reality, the development of this power source in Vietnam is very modest and not fully exploited. Solar power has predominant advantages than other natural power sources. For example, biomass power generation capacity is very modest while investment costs are high. As for wind power, according to calculations, to make 1MW of wind power requires 2 hectares, just only in some areas. Comparision with solar power, to produce 1MW just needs only 1 hectare of land and can be deployed in all regions of the country - especially the use of panels located on the roof. The cost of solar power is low, for example, solar panel connected to ...
