Fifteen thousand solar devotees from around the world are expected to meet in San Francisco this week in an event that organizers hope will “create strong global relationships.”

Actually, the sun worshippers will be fully-clothed (many in suits, no doubt). These movers and shakers, metaphorically speaking, will be attending the continent’s largest business-to-business solar trade conference and exhibition, called Intersolar, from July 14-16 at the Moscone Center.

Intersolar has been holding similar gatherings in Germany for eight years, helping businesses from across the solar supply chain meet, network and cut deals. The first North American Intersolar event was organized last year, as interest in clean and renewable energy sources in the US was beginning to grow.

With the Obama administration pumping billions of stimulus dollars into energy sources like solar, Intersolar organizers have expanded the North American trade show. Five hundred suppliers from over two dozen countries are setting up exhibits covering 120,000 square feet, three times the size of last year’s exhibition.

Grist thanks its sponsors. Become one.

Paula Mints, of Navigant Consulting PV Services, is helping to coordinate the event.

According to Mints, some of the topics being covered by speakers at the conference include, “low-cost methods for achieving higher efficiencies, new inverter technology options, thin film improvements, concentrating technologies, solar thermal power plants, solar air conditioning, and maximizing the value of solar power generation with smart grid.”
