Testing of commercial black painted for flat plate solar collector applications

Abstract

Abstract Hight absorption of absorber makes improve the performance of the collector. Solar coating should be safe from chemically, and structurally stable for the variable range of the temperatures. The high cost of coating collectors made an option to utilize commercial black paint to be a coating absorber. Commercial black painted for solar collector absorber surface was discussed. These are four commercial coatings was laboratory tested and compare to get the performance. Identify of properties commercial black painting was used to explore the utility of the coating surface. To improve the absorptance solar commercial coating have been used by the researchers. This would allow the use of the low-cost coating in the solar collectors.
