Solar absorber coatings based on blackened electroless nickel are reported in this study. Such coatings have an absorptance alpha of 0.94 and an emittance e of 0.15. At a solar radiation level of 800 W m-2 an equilibrium temperature of 155 deg.C was recorded compared with 160 deg.C and 96 deg.C for black chrome panels and black paint respectively under identical conditions. Electroless nickel was deposited at room temperature and then blackened in dilute HNO3 solution. The coatings were tested for thermal stability and compared with standard black chrome panels
