Why do the satellites never run out of power do they have batteries that are charged by sunlight everyday? Also they transmit so much information across the globe.
Actually, satellites may kind of run out of power when their solar panels stop working properly because they have degraded with age. Then we lose connection with them and they become just trash in orbit which is endangering other satellites and most importantly the ISS.
So yes, satellites use solar energy and it is enough, since those in space are much more efficient. At 500 kilometers a satellite is not exposed to direct sunshine for more than 38% of the time. Also on Earth you encounter with cloudy weather, storms and so on.
