What size/strength solar panel would I require to run an run of the mill laptop?
Answer:
The 110 volts is normally converted down to 16 or 20 volts DC. If you hold a 20 volt, 90 watt notebook that's about 4.5A of current needed to drive the components. Solar cell 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 stipulation to generate 540 watt-hours per day to sustain the notebook. You would requirement a sets of solar panels placed contained by parallel and then within series with other sets of solar panel.
If a set of four cells generate .45W x 1Hour = .45Watt-Hours then you call for (540/.45) = 1200 4 set panels.
But this depends on the output of the solar panel.
You involve to first create the voltage configuration to get 25volts. The two create the needed current you would place multiple voltage sets contained by parallel. This would run into a variable voltage controller and a current bypass circuit.
All of which requests to be on a fuse. You also need a fry sink on the voltage controller.
You need one that produces 120 volts (220 if surrounded by Europe) However this is the amount of electricity that goes into the computer at adjectives times otherwise it will not work. If you live in Europe on some computers you can switch the power needed final 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 be in motion from there.
here's a join on ebay to them
