• Multiple Gear ratios (see options)
• Multiple Strokes (see options)
• Input voltage: 0-15 VDC, Rated at 12VDC
• Stall current: 650mA @ 12V
• Comes with Potentiometer Feedback
Firgelli Technologies introduces the L16 Linear Actuators 12V w/ Potentiometer Feedback. Firgelli Technologies' unique line of Miniature Linear Actuators enables a new generation of motion-enabled product designs, with capabilities that have never before been combined in a device of this size. These linear actuators are a superior alternative to designing your own push/pull mechanisms.
The L16 actuators are complete, self contained linear motion devices with position feedback for sophisticated position control capabilities. Simply apply a DC voltage to extend the actuator, and reverse the polarity to retract it. The L16 is designed to push or pull a load along its full stroke length.

The applications for linear motors and linear actuators overlap, so maybe you can use a linear actuator
The latest issue of the catalog from American Science and Surplus, also found at , has a few linear actuators, but they are 12 volt, and cheap.
Similar, more expensive, units are found at the surplus giant Herbach and Rademan who have an online catalog
Personally, I would order by mail, rather than drive anywhere in S.F.
Your grid tie inverter2006-11-07 17:40:58 by solarmandotorg
From what i gathered from google, your inverter probably does use MPPT (maximum power point tracking).. read your manual and make sure though.
like i said, seasonal tilt makes a huge difference. you have about 3 times the panels i do. i leave mine in place but i can move them in about 10 minutes and that includes dragging the ladder out.
you could even set up some linear actuators to move them up and down. these are the things that swung the huge satellite dishes back in the 70' and 80s.. little moter with a long bolt that spins a nut up and down a pipe.. a tiny motor can really move something like that
Thomson introduces web-based sizing and selection tool for linear guides — The Engineer
Thomson has introduced Linear Guide Components, a sizing and selection tool that enables users to quickly configure, customise and select optimised round or square rail linear guides, with outputs that simplify and speed the machine design process.
