PARABOLIC TROUGH SOLAR MIRROR
Time：2019-11-01 18:17 Number of visits：
Parabolic Groove Solar Mirror will take a large area of parabolic trough solar mirrors to track the sun and achieve the maximum sunshine concentration on the collector tube, the transferred fluid in the tube will collect the solar radiation and convert the solar energy into heat, the heat will then generate steam to drive the steam turbine to generate elecricity.
