Draw a schematic diagram and show components of solar power plants.

The graph shows the variation with the incident solar intensity $\mathrm{I}$ of the temperature of a solar panel used to heat water. Thermal energy is extracted at a rate of $320 \mathrm{W}$ . The area of the panel is  $2.0 {\mathrm{m}}^2$. Calculate, for a solar intensity of $400 \mathrm{W}/{\mathrm{m}}^2$, the temperature of the water,

Explain the difference.

Thermal electricity generation and solar thermal electricity generation.

A diagram of OTEC (Ocean Thermal Energy Conversion) system is given below. In which part water is converted into water vapours?  

Sunlight of intensity of $700 {\mathrm{Wm}}^{-2}$ is captured with $70\%$ efficiency by a solar panel, which then sends the captured energy into a house with $50\%$efficiency. a. The house loses thermal energy through bad insulation at a rate of $3.0 \mathrm{kW}$. Find the area of the solar panel needed in order to keep the temperature of the house constant.
