I have a standard laptop, I think it requires 110v to run. If I'm looking to run the computer for around 5 or 6 hours a day, what size or strength (ball park figure, as I'm aware there are many different factors relating to power consumption) of solar panel I would need to do this? If more details are needed, let me know. Thanks.

The 110 volts is normally converted down to 16 or 20 volts DC. If you have a 20 volt, 90 watt notebook that's about 4.5A of current needed to drive the components. Solar cells already output DC.
Most notebooks transform the 110V down to the 16V or 20V through the power pack attached to the AC cord. So the power port on the notebook is a DC input.
You would need to generate 540 watt-hours per day to sustain the notebook. You would need a sets of solar panels placed in parallel and then in series with other sets of solar panels.
If a set of four cells generates .45W x 1Hour = .45Watt-Hours then you need (540/.45) = 1200 4 set panels.
But this depends on the output of the solar panel.
You need to first create the voltage configuration to get 25volts. The two create the needed current you would place multiple voltage sets in parallel. This would run into a variable voltage controller and a current bypass circuit.
All of which needs to be on a fuse. You also need a heat sink on the voltage controller.

You need one that produces 120 volts (220 if in Europe) However this is the amount of electricity that goes into the computer at all times otherwise it will not work. If you live in Europe on some computers you can switch the power needed back to 120.

Your laptop probably has a power adapter that PLUGS INTO a 100V AC circuit.
Usually they provide DC volts to the laptop itself.
Look on the power adapter and see if it states what the output voltage is AND the amps (A) or milliamps (ma).
Then you can go from there.
