Solar shades, also called solar screen shades are a type of roller shade typically made from a synthetic mesh fabric.  Solar screen shades come in different levels of opaqueness depending on how much light control or privacy you desire.

Solar screen shades offer an alternative to standard roller shades by the fact that solar screen shades reduce the glare of the sun thereby protecting your furnishings from harmful UV rays, all while maintaining a view of the outside.

Solar screen shades are not totally private.  In the daytime, you can see out and people cannot see in.  It is just the opposite at night.  If total privacy is an issue, the solar screen shades may not be a good option.
