I came across the Airbus Maverick concept and using the provided model dimensions I scaled it up to see how large the actual model could be. Seeing how large the surface area on the rather flat upper surface is, I wondered how much fuel would solar panels save.https://mobdro.bio/ https://kodi.bio/

I arrived at an estimated 1000m2 that could potentially be covered with solar cells. Using an average 200W/m2 (during day in direct sunlight) this would result in 200 kW of power. Per hour this would amount to 72 MJ of energy. I looked up energy density of jet fuel, turns out to be around 45 MJ/kg...assuming 100% engine efficiency this would mean the solar energy would only save 1.6kg/hr? Is that correct or have I made a mistake somewhere? I am aware this is a massive simplification of the problem, but just wanted to get a rough estimate.

Thanks!

The aircraft is a single-seated monoplane powered by photovoltaic cells; it is capable of taking off under its own power. The prototype, often referred to as Solar Impulse 1, was designed to remain airborne up to 36 hours. It conducted its first test flight in December 2009.
