you donot believe that if some of the sunlight is reflected back then the heating inside will be slower. Clearly that is stupidity of the first and second order.

Indeed I do not believe that reflecting back some of the sunlight will slow the heating of the inside. What it will do is drop the equilibrium temperature of the inside. Any idiot knows that. The time constant of the rise remains identical. Which is why I told you to consider a basic 2'nd order system. What do you think the rise time of a 2'nd order system does in response to a step function of magnitude X vs one of magnitude 2X? Is it the same or different? What is the magnitude of the steady state output? What is the magnitude of the maximum rate of change of the system output in response to these two inputs? Assume a damped 2'nd order system (make it critically damped for the heck of it) without a pole at the origin. When you can answer those questions, you will understand things.
