This is the preliminary calculation about the potential of solar power from second-floor+ houses along Hung Vuong Street, Hue city. Research team organized field trips to inventory the houses and areas, number of floors, sunshine direction of the house in accordance with its adjacent houses. We calculated the number of solar panels needed to install and the potential of solar power can be generated from each house from the second floor and more. Research team has chosen photovoltaic solar cell technology (PV) to calculate the actual solar power achieved. The calculated results of solar power reserves are 3GWh/year with an investment of 57 billion VND (not including inverter). This reserves can help to reduce 4.17 million tons of CO2, 19.08 million tons of nitrogen oxide, 0.06 million tons of sulfur dioxide, 3.12 million tons dust, 1.14 million tons of ash, 9.12 million m3 of water and 2.55 million tons of coal annually, if the lifetime of the solar system is 25 years, the emissions will decrease significantly. This research shows that the potential for solar power conversion is feasible to address the green growth needs of the economy and climate protection in Thua Thien Hue province.
