For a while developments in solar panel costs have been getting all the attention, but recently innovations in solar panel applications are getting their time in the...sun. This article describes three different applications:
1000 sqft solar mirrors that generate enough energy per year to power 24 homes, but require much less land (and no water!) compared to conventional concentrated solar systems.
A system designed to generate continuous solar energy, day and night, rain or shine, by connecting 4 - 8 PV panels to a 6'x8' 'Power Pod' that contains a turbine generator
Printable, flexible, organic PV panels ranging in size from the back of a smartphone to a large window - these have been in development for years but are only now becoming commercially
...AND NOT YOUR GRANDMA'S STAINED GLASS WINDOWS
Another innovative use of PVs. It's a contemporary stained glass window, energy source, and phone/tablet charging station all in one.
