Abstract
The excessive development and utilization of traditional energy makes the energy fuel (oil, coal, etc.) on the earth tend to be exhausted. At the same time, the pollutants discharged in the process of use have caused serious harm to our living environment, resulting in increasingly acute environmental problems such as climate warming and air pollution. Solar energy is inexhaustible clean energy. At present, the use of solar energy in Jinan residential buildings mainly focuses on the installation of solar water heating system in the south facade of the building, while the use of roof of residential buildings is very little. There are two ways to use solar energy on the roof of residential buildings: photovoltaic power generation and light heat conversion. Through these two ways, solar energy is converted into electric energy and thermal energy. There are many favorable factors to promote the use of solar roof in Jinan residential building. First of all, Jinan has a long sunshine time. Secondly, the usable area of Jinan residential building roof is large. In addition, the solar energy roof of Jinan residential building has a double energy-saving effect. Finally, the solar energy roof has little adverse effect on the appearance of the residential building in Jinan.
