I am currently trying to solve a problem for my dissertation. Help would be greatly appreciated. :)

A silicon solar panel of area 1m^2 is being warmed by the sun. It achieves a constant temperature of 80 degrees celcius.

I am trying to cool this panel which is constantly being provided solar radiation. The equilibrium temperature would be 80, however, I am trying to cool it down to 50 degrees celcius. Would the rate at which I need to expel the energy simply be q= c*(80-50)m? c- being specific heat, m being mass and delta T being temp difference? In that case I obtained a value of 4.96 kJ per second.

I am trying to cool this panel using flowing water which is at 30 degrees celcius. How would I calculate the mass flow rate of water to obtain desirable cooling? Thank you for your time!
