Today in Cleantech

Intersolar North America kicks off at San Francisco’s Moscone Center tomorrow — what’s on the minds of the solar power movers and shakers in attendance? Here’s a roundup of preview coverage to give a sense of the hot topics at hand. Earth2Tech’s own Ucilia Wang lays out a five-point list that includes a focus on California as an early test market for the proposition of getting one-third of a region’s power from renewable resources, including intermittent solar, and the corresponding need to figure out ways to either store that energy or shift demand to times when solar can meet it. There’s also an interest in new markets for solar, with Europe seeing sluggish sales and the promise of U.S. solar market growth facing a potential backlash from political intransigence and economic uncertainty. From Greentech Media, here’s an introduction to some of the first of what’s likely to be many announcements in the field of concentrating photovoltaic (CPV) systems, as well as a focus on the balance-of-systems equipment debates underway, such as the relative merits of central inverters vs. microinverters, and how competitors in the latter group fare against one another. From the conference itself, here’s a running feed of all the press releases and announcements coming out of the show. Enjoy the sun.
