   Of course you can. A robot that is built around a frame that is lighter than air (like a blimp or zeppelin) can easily be designed to be solar powered. Solar power doesn’t provide enough energy for a regular airplane, but since blimps don’t need power to float they are ideal for solar-powered vehicles.

   However, such a robot would be of only limited use on other planets.

   Some planets, like Mercury, have no atmosphere at all, so such a vehicle could not fly. Other planets like Mars have very thin atmospheres so a blimp-type aircraft would have to be enormous to fly.

   Some planets have thick atmospheres. Venus, for example, has an atmosphere much thicker than ours. However, Venus’ atmosphere is very cloudy so any solar-powered vehicles would have to remain above the cloud tops to remain powered. And the clouds are made of sulfuric acid, and are extremely hot, so your aerobot would have to be very sturdy in order to survive.

   Other planets like Jupiter and Saturn have atmospheres that are less dangerous than that of Venus. However, at Jupiter the sun only provides 1/25th the energy it provides here on Earth, and like Venus, Jupiter is pretty cloudy. Saturn is even worse, receiving 1/100th of the solar energy that we get here. The planets of Uranus and Neptune are even further away.

   So in short, on planets where solar energy is easily available, such as Mars and Mercury, an aerobot wouldn’t be able to fly. But on planets where an aerobot could fly, like Venus or Jupiter, solar energy isn’t really an effective power source.

   yes,solar energy can be harness in a space mission but the photoradiation about which are talking
   is very weak so it is can become as main fuel but we can use it as alternative source
