Why pipe of solar heater and container of solar cookers are painted black?

We see objects as black because they do not reflect any of the wavelengths of light that shine on them. A matte surface is matte precisely because it isn't shiny - in other words, because it doesn't reflect the light very well. Matte black is least prone to reflect energy and best at absorbing it. In the case of hot water panels, it is the solar energy that is absorbed that heats the water so the more efficient the panels are at absorbing it, the better it does at heating up the water.
