Looks like Ten K Solar is doing pretty well, new deal in China. http://tenksolar.com/news/   As you can see the image of the solar panels is the same as in Electrovaya's presentations. http://tenksolar.com/products/reflect/   Electrovaya is one of their partners.  http://tenksolar.com/alliance/  They show they are compatible with other batteries but list only Electrovaya as their partner. http://tenksolar.com/technology/storage/  Their new Chinese partner looks impressive as well, this is going to require further invesigation. http://www.asiacleancapital.com/acc-ten-k-solar-en/
