  • Solar Power..any one run one of these?

    http://www.solarenergyalliance.com/s...%20laptops.htm

    Be curious to see if anyone has ever adapted one of these for their in car power use?

    "They provide power even with bullet holes or in partial shade."

    sounds like a selling point to me

        you know - i bet it wouldnt be too trivial to have that hooked up in a laptop in a car, and keep the laptop running 24/7. Of course, there would be some catches, such as shady days. You'd need to get the biggest battery for yor laptop and so on,

            Man, why are solar panels still so expensive.

            The technology has been around for so long now, you would think this stuff would be dirt cheap. But over 400 for that!

            Not from my wallet!

              No one pushes the technology for anything but LARGE arrays, and the average consumer couldnt afford that so its a niche market and thusly R&D costs are always high.

                I'm curious whether the technology WOULD allow for a 24/7 running car computer. I mean, would it act as a capacitor too storing energy so that the computer could run on non-sunny days? This would solve my remote laptop power on scheme

                  No, the cells do not act as a capacitor, nor is a capacitor what you are looking at incorporating (they are used for quick/short bursts of stored power, not long/sustained power supply). You would need a rechargeable battery. I'm not a battery expert but my instincts tell me you could go one of two routes:

                  1. a deep cycle marine battery powering your laptop (or carPC for that matter) that you could try and charge from both the solar cells and your alternator (when the car is running... and this may require a stronger alternator in your vehicle... but this also has a whole host of issues of itself)

                  or 2.) find a laptop with two modular bays and put the largest battery they provide in each. sony or dell would be good for something like this as they both have models that do this exact thing. I do not know how long you could run the laptop off of two batteries, however. you may be able to suppliment this solution with a small car battery as well, but again, anytime you start talking about adding a second battery to a car and having the car charge the battery, there are a large amount of considerations that come into play...

                    Like if you can afford to get all the materials needed in order to get the needed amount of watts to power your carputer, then you can afford to do something cheaper.

                      they do infact have cheep solar pannels. but the eff. on them is even lower than the good ones which iirc were down to 15%. so 5-10% eff. isnt a problem when you are putting them ontop of your warehouse, but in the back window of your car, you want as much as you can get for that small amount of realestate.

                      personally, ill be running something like this eventually when i get my aux cooling setup(cools when the car is off in the sun, ie 150F internal tempsl.)
