flat panel solar collectors

 Higher absorption rate and lower reflection rate ensures the higher conversion rate of the whole system.  
From the research and test results on solar energy of the whole world, the most ideal selective coating material for heat assorting fin is copper strip with selectively plated black chrome. It is featured as high thermal conductivity, , excellent durability, moisture proof, anti-oxidation, good durability of temperature change, good thermal stability and easy maintenance.

MingZhuang M-plate solar collector plate has red copper core with black chrome coating, which has an excellent spectral selectivity, thermal stability and anti-high temperature performance for high-temperature conditions. It can work under 300 degrees conditions for long time. In addition, the black chrome coating also has good corrosion resistance and weather- ability.
    The solar collectors will be mainly based on flat-plate collector in the future. The conversion efficiency between sun irradiation and thermal depends on surface coating materials of the panel. We devote ourselves to improve the absorption rate of the selective surface and reduce the reflection rate. The higher the absorption rate of the selective surface has the better. To sustain the absorbed sun irradiation as much as possible, the lower reflection rate of the surface has the better.
