- A monocrystalline silicon solar panel (active area: 1m2 )has an energy conversion efficiency of 20%. What is the power output when irradiance of 800 W/m2 is shining on the solar panel? a. 320 W. b. 80 W. c. 240 W. d. 160 W. e. 400 W.Q20. A certain gas in a closed container at 0.001 atmospheres of pressure is irradiated with ionizing radiation, causing on average one electron to be stripped off each atom. The ionizing radiation also heats the gas from 20°C to 3000°C. The resulting ionized gas ("plasma") behaves like an ideal gas. What is the pressure in the plasma? a. 4.92'103 Pa b. 3.04'105 Pa O c. 1.23'103 Pa d. 2.26'103 Pa Clear my choice6.
