    Peg board would be just fine, shear reinforcement doesn’t need to be very strong at all to give a lot of benefit.

    I know it has been said by many others but it is important, FUSE. I would have taped into the power distribution box (let the manufacture tap to the battery). I would also have looked to tap into a circuit controlled by the ignition. I would make for a bad day trying to start your car and no power because the seats were left on.

    Anyone ever tried a Peltier? heated and cooled seats?

    This was really interesting, although with the approximately 13% mobile users, how about a slightly more mobile friendly site (although it has improved over the last few years).

    Thank you for supporting the government employees who are without jobs by no wrong doing of their own. You get it that government employees are not the ones who get to make the call. While I am not one of the currently furloughed federal employees, most of my coworkers were in the same situation when a certain state shutdown a few years ago, it is a huge impact on their lives. This just gave me one more reason to support sparkfun as much as I can, you guys ROCK, thanks for being awesome.

    Although one should take into account that in poor weather the system is less likely to be used, so you could go with a less conservative value (I looked at the NREL Red Book and got about 7-8 as reasonable).

    You are absolutely right though that especially for systems looking for year round use more power will be needed. Thats how I have a 800w system driving a 3 amp load (extreme case).

    With GPS accuracy and speed are goals at odds with each other. I would say you could use the GPS for basic vario functions, however augment it with the pressure altitude you are also collecting. You should be able to read it far quicker and more accurately. I am thinking something like using the GPS altitude to “calibrate” or relate the pressure altitude to GPS altitude. As a addon if you went to a more powerful processor you could find and download a DEM (digital elevation model) and get your ground altitude over the actual ground you are currently over as well as referenced to your airport. Sounds like a fun project.

    One thing you didn’t mention was the rated power is at standard test conditions, which may not be realistic for your application. For a project I was derating my panels to less than half the “nameplate” power. I admit it was an extreme case; 100% up time, safety application, northern climate (snow, low insolation); but I would not expect to get what the spec sheet says.
