To be more serious, a Cessna 152 has an 82 kW engine and a wing area of 14.9 m^2. On a sunny day (1 kW/m^2) with 20% efficient panels and a 90% efficient motor, the solar panels would supply 3.2% of that power. So it's not possible to build a solar plane this way, but it's not 0.01% either. https://en.m.wikipedia.org/wiki/Cessna_152 https://en.m.wikipedia.org/wiki/Cessna_152
