Solar panels are employed to heat a body of water with a mass of $500\,\text{kg}$. The combined area of the solar panels is $10\,\text{m}^2$, and the mean power output from each square metre of the panels is $300\,\text{W}$. The specific heat capacity of water is $4200\,\text{J kg}^{-1}\,\text{^{\circ}C}^{-1}$. Determine the rise in the water temperature after $8.0\,\text{hours}$. Assume that no heat is lost.
