I have an old friend, Mark MacDonald, who has
started up a business of solar tracking devices; Home Concentrated Solar Power, Home CSP; http://homecsp.com.
He is offering a lot of stuff including single
and dual axis tracking controllers as well as temperature-differential
controllers, linear actuators, and motor drives.
SolarMEGA1A single axis controller
From his site “Recent developments in
microprocessors and embedded software technology have allowed the creation
low-cost specialized controllers capable of the sophisticated analysis needed
to make CSP convenient, practical, and affordable. By combining the latest
micro-electronics technology with physics, and astronomy, and applying results
to the needs of the home, a truly new paradigm of energy usage is possible.”
There is also info on Solar Boiler Hydronics,
Heat Exchangers, Temperature Differential Controllers, and one of his latest
endeavor compound parabolic trough project.
http://homecsp.com has information guides on projects
plus a blog. He has some new stuff on a bicycle frame tracker. Although most stuff is too technical for
me to totally understand Home Concentrated Solar Power is on the right track
for affordable embedded software and electronics products for controlling all
aspects of home solar systems.
