Solar compound parabolic concentrator (CPC) has the characteristics of no need for real-time tracking
adjustable acceptance half-angle
and simultaneous receiving of beam and diffuse radiation
however
conventional CPC concentrating surfaces are not easy to produce
transport
install
and maintain. Therefore
in this research
a congruent multi-section asymmetric CPC (MA-CPC) is novelty constructed and its structural characteristics
concentrating properties and economic feasibility are explored. Based on the congruent concentrating plane technology
and coupled with 3D printing manufacturing technology
plane concentrating mirrors and solar vacuum tubes to construct a solar MA-CPC experimental setup
the reliability of the concentrating characteristics of MA-CPC is verified using laser experiments. Following this
the optical efficiency
solar radiation collection
concentrating uniformity and economic efficiency characteristics of the MA-CPC system are analyzed and discussed. It is found that solar MA-CPC can achieve higher collection of radiant energy in the autumn and winter seasons
and the solar radiation gathered to the absorber surface has better uniformity than the same size N-CPC. The results also show that the constructed solar MA-CPC has a significant advantage over N-CPC in terms of annual radiant energy output for the same investment
