So it keeps the battery charged while your using it? I think it would be a cool idea as long as its feasible? What do you guys think?
Would a solar panel Incorporated into a laptop lid work?

It sounds like a good idea but I don't think it will work very good. Most of the time, your laptop will be:
- In a bag
- On and used, meaning the lid will be facing at least 90 -

I tried that once, with a 20 watt panel. It worked OK, but would only charge when the laptop was off. The battery died after about three weeks, though - the laptop was just smoking hot all the time and that killed the battery very quickly. You are MUCH MUCH better off having the panel be separate so the heat doesn't get transferred to the battery, and you don't have to leave the laptop in the sun.Comment

The lid would not be large enough for the panel required to keep up with the computers draw. Look at the WATTs supplied by the charger. Then look at how big a panel is that can supply that wattage.

This is a bit silly. a laptop has around 1 foot square surface area. Using the highest efficient panel you can buy is 19% or so. That works out to about 18 to 19 watts at best at noon facing directly into the sun on a bright sunny day with very low humidity.MSEE, PEComment

If the laptop has a 27" LED screen and the rear of the panel can be glycol cooled with a small radiator mounted under the laptop it should be feasible under good sun conditions providing you also place a mirror the same size as the panel flat on the desk behind the laptop to reflect the sunlight on the the panel.Comment

You know.... you guys are being silly but... it would be kind of nice to have a solar panel on it if it would at least make the battery last longer. You guys always seem to think we need to address the entire energy needs. Well I understand why, you wouldn't put only 3 gallons of gas in your car if the trip requires 5. But what I'm getting at is if you give me 1 gallon, I only need to buy 4.Comment

Take the practicality issue. How many times have you found yourself outside with your laptop with the back of the screen where the panel would be facing up into the sun. Or how about leaving your laptop outside broiling in the sun.MSEE, PEComment
