Solar absorber coatings are produced by the galvanic deposition technique from an electrolyte containing nickel chloride 100g/l, stannous chloride 5g/l, ammonium bifluoride 30g/l at a pH of 6.0-6.5 and temperature 30-35 °C by employing magnesium as counter electrode. Optical properties of solar absorptance 0.95 and thermal emittance of 0.11 are achieved in a time duration of 120 seconds. This technique is characterized by its simplicity, low cost, low capital investment and longer time duration required for the production of selective coating in comparison to very short durations (15-45 seconds) required for conventional black chrome coatings at a current density of 20 A/dm2
