Abstract
Various selective coatings have been reported in the literature to improve the efficiency of flat plate solar collectors. In order to protect the solar absorbers from corrosion and to provide low emissive surface, nickel undercoats are widely used in the flat plate solar collector systems like solar hot water, hot air etc. With increasing trend in the cost of nickel, replacement for nickel coatings are being investigated in this laboratory. Suitability of zinc-cobalt alloy deposits as an undercoat to selective black coating is examined
