Solar Powered Sun Bricks

These aren't the first solar powered walkway tiles we've seen, but they are the largest. The previously linked sets were smaller and perhaps easier to integrate into some tile work, but this version of the same idea comes in more of a standard brick size - and in the end, the more options the better, really. From the site:

Flush-to-the-ground, integral solar panels generate up to 8 hours of light each night. So guests can follow a cheerfully illuminated path to your door...Sun Bricks come on automatically when darkness falls, and incur no operating costs. Just recess them in your walkway, and forget them!
