high quality solar collector

OWON M-plate solar collector plate is copper core, black chrome coating 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 future. Flat-plate collector light and thermal conversion efficiency depends on surface coating materials of panel, how to improve the surface of selective absorption rate and lower reflection the rate is our goal. Require the higher absorption rate, the better, in order to keep the absorbed radiation, require the lower reflection rate the better. Higher absorption rate and lower reflection rate help entire system get higher conversion rate.
    From the world of solar energy research results, to date, recognized the best there is for the selective absorption of heat-fin coating material is selective and chromium-plated copper, the material of heat transfer efficiency , Corrosion-resistant, very good durability, moisture, oxidation, resistance, low temperature-resistant high-change, good thermal stability, and other fine features, and simple to maintain collector.
