The higher the concentration, the more accuracy required in the sun tracker.
An eqitorial mount, where the rotation axis is parallel to the earth's axis
at the installation location, is a good start. However, as the seasons
progress, the sun's elevatiion changes, so the tracker must operated in

This firm, Solargenix was owned by Duke Energy and now owned by a Spanish
consortium. They are marketing their electric power producing system across
the world and putting some very interesting contracts together. One of their
secrets is keeping the cost of operations low.. that

Howdy Jones,
Looks like Sun-glitch has figured out a way to use seal beam headlamps for
solar concentrators.. probably be lotsa old cars with empty tanks missing
headlights it these guys can get off the ground.
Vancouver has become the rival of Las Vegas for creating a whole new
industry of

There is an added cost, of course, but supposedly
there would also be a fast payback, especially in
winter and especially for modular

Non-focusing concentrators have been devised, but such are not shown.

It's so much fun to hear all you folks speculate on what's happening in this
particular field. First, no one or no company has beat me to the punch in
using fresnel lenses to concentrate sunlight for a photovoltaic system. This is
an old and obvious idea, newly revived because of the run up in
--- Michael,
Hey, we kibitzers were merely waiting for you to
focus some light on the subject, so to speak ...
BTW- have you had a comparative look at what would be
the optimum level of 'shrinkage' for the solar cell
itself when under Fresnel concentration ?
