Intersolar North America 2014 Day 3 Exhibit Highlights PDF Print E-mail

I always enjoy attending the Intersolar Exhibition. The product and technology demos on display are very diverse and there are always some good “take aways”. I will share with you some things I observed while attending Day 3.

This year, similar to past years, the three floors of the San Francisco Moscone West Hall were organized by the various areas within the Solar landscape.  On Level 1 there were PV Cells, Modules & Systems, PV Manufacturing Equipment, and PV Materials & Components. Level 2 was full of companies dealing with Energy Storage, Balance of Systems, and Solar Heating & Cooling Technologies. Level 3 topped off the exhibition with miscellaneous PV components and items related to Mounting & Tracking. This year was the seventh annual occurrence of this event. The exhibition floor space seemed to be a bit smaller than last year.
