California’s Distributed Energy Future

GTM Research has established itself as the premier source of information on solar industry trends and developments in the United States. It’s instructive that from that perspective, they chose to organize a conference focusing on a single state, California. We who participate in the solar industry here have recognized the state as a leader, but the less patronizing among us also recognize that the magnitude of this lead is only temporary. If solar is to realize its potential as one means of reducing environmental damage while reducing future customer utility costs, then other parts of the United States need to catch up

Yikes! Is California’s interest in Solar Energy Collapsing?

GTM Research and the Solar Energy Industries Association (SEIA) released their US Solar Market Insight 2015 Year in Review on Wednesday, March 9. We’ve been tracking their PV capacity reports for the past several years, and in the figure below we plot the 2015 capacity increases reported in their Executive Summary. While there was strong national growth in installation capacity this past year, California’s capacity additions were less than in 2014. After a couple years of providing over half the annual capacity additions in the country (57% last year), California’s share has fallen to a mere 45%.

Solar Power International: Moving into Second Gear?

It’s a challenge to summarize what transpired over four days at an event with 600 exhibits, 70 concurrent sessions (forcing choice between 6 at a time), 15 manufacturer-sponsored hands-on training sessions, 10 workshops, plenary sessions, parties and, oh, did I mention solar-supportive keynote remarks by Vice President Joe Biden to an enthusiastic audience. With participants from over 75 countries, it’s easy to see why Solar Power International (SPI) claims to be the largest and fastest growing solar conference in North America. But let me try to extract a few themes from this mid-September event sprawled across all four Exhibit Halls at the Anaheim Convention Center.

InterSolar 2015: Industry Growth or Decline is Up to Us

One advantage of living in San Francisco is that the world periodically beats a path to our doorstep. For solar professionals and aficionados, this has happened for the past eight July’s with InterSolar North America at the Moscone Convention Center, the show claiming the highest attendance of any solar event in North America. I have attended these since 2012, by which time attendance had reached approximately 18,000 visitors (excluding exhibitors), a level it has since sustained.
