Light Thru

I’m interested in a PV array for the home.  My research has led me to a couple more architecturally pleasing panels such as the Sanyo double HIT and the Suntech light thru.  Both panels seem to have the ability to be installed in an application such as a patio cover and can provide partial light/shade while generating power.  I like the partial lighting idea, However, the Suntech panel does not seem readily available and I don’t really need a double sided HIT panel at close to $1,000 a unit.  Does anyone know if there is another manufacturer with a similar style panel that is readily available?  thks
