Research on active solar energy comprehensive utilization system for Tibetan rural dwelling

Abstract

In view of the problem that in rural Tibet the solar radiation is too strong and the deep plan of traditional residential buildings has resulted in poor natural lighting, the author proposed an active natural daylighting system. The system makes full use of the abundant solar energy resources in Tibet without changing the existing structure of the building. It improves the living environment and the indoor comfort by four working modes, including light reflection guidance, thin film amorphous silicon photovoltaic power generation, Synergistic application of lighting and shading and building insulation. The research results show that with this system, the indoor illumination time extends by 3 hours and the average indoor light depth increases by more than 3.5m. Meanwhile, 119.58 degrees’ electric power can be provided per year and the building thermal insulation performance can be improved. This system has broad application prospects in rural areas of Tibet and may inspire new ideas for other relevant design.
