Solar panels and powering

I was reading an email from Kenneth (an engineer at Queens) and the targeted advertisements from google came up with the following:

http://www.solarland.com/sd1/page1/home%20system.html
}This is a really wide selection of complete systems (panels, wiring, and lights) for various uses. everything from boats to homes.

http://www.ctsolar.com/
}These are more targeted towards laptops and wilderness excursions. The website seems kinda hacked together at the last minute, and so gives me the impression of sketchy... shrugs

}and finally, the selection of links provided. They're all commercial of course, but some of them seem worth looking into.
