They appear black because they do not rreflect light but rather than absorb photons as heat they absorb them as electricity. This conversion means they do not get hot like a painted black surface does. In fact, solar panels are heat sensitive and become inefficient if too hot, so some have cooling on the back side or even water cooling.
