Solar Roof Application In Spatial Structure And PV-Roof Panel System Design And Research

As China's determination to improve energy efficiency and "Green Architecture" and increasing application ratio of the spatial structure in modern architecture, the energy efficiency of the spatial structure is under more and more public attention. To integrate solar energy into spatial sturecture for sure will be the trend in architecture area. This paper focus on the solar application forms on the roof of spatial structure, and based on PV roof application, a type of integrated PV roof panel system developed by the writer is explained in details, and for the solar cell back panel and ventilation problems found in the above mentioned roof panel system developing process, the relating theory is studied and two foundamental experiments has been conducted.There are lots of forms for solar application in architecture, and this paper groups them into three main forms: solar thermal application, PV application and sunlight application, and each form is explained in details.Based on PV application, the writer develops a integrated PV roof panel system for spatial stucture. As an integrated roof panel system, it can generate power besides the normal roof function such as weight-bearing, water-tight, insulation, and compared to the other forms of PV roof system, it is much simple, reliable, quick-installation and less material consumption.For the solar cell back panel and ventilation problems, the relating theory is studied and two particular experiments has been conducted. The back panel experiment is to research the influence to the solar cell as of differental kinds of back panel material. Four differental types of back panel has been selected in this experiment, and the V_OC, I_SC and temperature features of the solar cell has been recorded during the experiment phase and comes some results. The ventilation experiment is to research the influence to the solar cell as of the ventilation conditions, three ventilation conditions is used: non-ventilation, 25W*2 ventilation system, 40W*2 ventilation system, the V_OC, I_SC, temperature and ventilation speed features has been recorded during the experiment process and comes some results.
