		<description>The system described and shown above now comes with a more powerful 62.6 peak watt foldable solar panel, and costs $1700.  Another system includes a pair of 12-volt, 18AH batteries configured in series to deliver 24 volts, instead of using a step-up DC converter.  It&#039;s heavier, stores twice as much power, includes the larger foldable solar panel, includes two charge controllers, and costs $1900.  We can make these systems as small or as large as one requires, and use multiple solar panels for more power and faster charging.</description>

		<description>Hey John
I have a question, I&#039;m a Senior in my High School and I&#039;m working on a physics project, which involves transvering an electric powered moteor into a solar powered motor. I would appreciate some more detailed information or tips or pics
Thx

		<description>That&#039;s pretty cool.  Small aircraft batteries are known for being pretty small capacity (since planes are so weight-sensitive) so it&#039;s a common complaint that the avionics can&#039;t be run on the ground for very long without a danger of making it impossible to crank the engine afterwards.  (engine cranking requires a ridiculous amount of energy).  also people generally don&#039;t like starting their engines without needing to because of the wear and tear on the cylinders from a cold-start.  and it&#039;s just plain dangerous to have the engine running on the ground for a long time while your head is down in the cockpit.  plus, if the engine is on, you can&#039;t get out of the pilot&#039;s seat.  so external power is a great solution for exactly what this guy said - doing preflight planning while you&#039;re packing, etc.
