In order to reduce the radiation heat loss during heat transfer in a fairly high temperature, two types of evacuated collector tubes with inner radiation shield were hereby put forward.

An idea about product factor of incidence is raised,the product factor of incidence is calculated and compared on the single horizontal aside solar evacuated collector tube and single tilted aside solar evacuated collector tube,a conclusion is obtained which tilted aside is better than horizontal aside,but it is limited to single tube.

In this paper, the design requirements and constructure speciality of pumping station for the solar evacuated collector tubes are reported.

According to the Clear-Day Model,the daily energy gain and its annual variation for different center-to-center distances of evacuated collector with cylindric absorber in two different axes installation on horizontal plane are studied.

According to the Clear-Day Model,the daily energy gain and its annual variation for different center-to-center distances of evacuated collector with cylindrical absorber in two different axes installation on building southern facade were studied.
