solar cell info

 1 sun produce roughly 1000 Watt/metre square
 1 sun = 100mW/cm2
 if effeciency is 24%, we can generate 24mW/cm2 or 240 watt/m2
 basic electrical device need 240 Watt to function
 so if we can generate 24% solar cell we can TV with free using 1 m2 solar panel.
 but we must measure how many watt per hour a solar panel can produce...
