I also learned that a macbook can take the power brick from a macbook
pro which has a higher voltage (18.35V) than the stock power source
(16.5V) which means that there's some tolerance for varying voltage.

I guess my question is:
For the purpose of trickle charging a laptop through a solar panel, do
I need to worry about anything other than voltage (given that Wattage
and Current will be lower than the normal power source)

As long as the voltage is within the expected range, can I just charge
directly from the panels into the power input of the laptop? Am I
being too hopeful?

The input to the laptop is a special power supply designed to charge the Li
battery. You will starve the supply and could cause damage to the charger or
battery.

This assumes the ratings on the AC charger are realistic and not maximums.

In any event, you won't be trickle charging the battery. Charging Li
batteries is a critical process and requires a smart charger>

I would be careful.
