    Heat transfer problem for cooling a solar panel

    the water is from a reservoir and starts off at 30 degrees celcius.

    Heat transfer problem for cooling a solar panel

    I see, if I wanted to keep it at a lower temperature, I would have to remove the radiation from the sun. That means with a flow rate of water, the lowest temperature of the silicon I can achieve is 30 degrees C, but the flow rate of water would have to be increased drastically. For my problem...

    Heat transfer problem for cooling a solar panel

    I am not understanding what you mean 0.233 (mass of silicon) x 30 (temp I am trying to reduce silicon by) x 0.71 (specific heat capacity of silicon) = 4.96kJ wouldn't this be the heat required to be rejected? since equilibrium is at 80 degrees, is 4.96kJ what would be required to be rejected...

    Heat transfer problem for cooling a solar panel

    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...
