a solar cell of area 2m^2 has maximum a power output per unit area of 20W/m^2 . if four solar cells are used together at once, how much energy is release in 2 mins at max power output?
max output of 1 cell = 20x2= 40w , so four cells gives 4x40 = 160w so if it gives 160 joules a second then in 2 mins it will put out 160 x (2x60) = 19200 joules
