Is there a way to adapt a solar panel to my quadcopter to increase flight time?

I would say no. You are talking about a panel that would be producing milliamps of current (given the physical size and voltage requirements) in hopes of charging your main battery that is sucking down amps of current. It would be much like pouring a cup of water into a swimming pool and wondering why you didn't notice the level increase.

And as was already mentioned, the power to weight ratio would be in the negative category.

There's a way to add a solar panel and decrease flight time! Adding solar panel adds weight. Will the power that the solar panel add over the duration of the flight equal or be more than the energy required to lift it. Doubtful is being optimistic. Solar panels work on lanes and planes can require less energy fly.

Using solar power charge batteries on the ground is more useful. But would be slooooow.
