It is not so easy.

Airliners have fuel efficiency about 2-3 L/seat/100km.
( Many people are not aware of
the flying is more energy efficient than 1 person car driving  )
https://en.wikipedia.org/wiki/Fuel_economy_in_aircraft#Example_Values

For 200 people and 900 km/h it is 3600-5400 L/hour.
If I estimate fuel specific energy 10 MJ / L
it is 36-54 GJ / h = 10-15 MJ/s = 10-15 MW.

If I suppose panels providing 200 W /sq m,
it is 50000-75000 sq meters,
what makes area 1000 x 50-75 metres.

We do not use airplanes with such a vertical crosssection area. (smile)
And even if we do, it would not take off it there is cloudy.

Another technological challange is power supply, if batteries are used.
Aside of the price, batteries are known to be very inferior to fuels
in energy/mass parameter, what is show stopper for flying.

Another technological challange is electric engine technology,
as current implementations using just propeller engines
that are efficient for slow airplanes only.

As resume, for airliners I see as real only cases
the planes ARE powered by fuel,
but synthetically prepared with solar energy use.
In such cases the carbon cycle is closed.
