Santa Barbara, California, Dedicates Their Solar Power System Today, March 11, 2009

Santa Barbara, California, dedicates their solar power system today, March 11, 2009 with a ceremony and educational tour from 2:00pm through 3:00pm in the David Gebhard Meeting Room, at 630 Garden Street.

Santa Barbara's City Corporate Yard solar system can produce 550,000 kWh of energy per year, effectively offsetting 421,466 lbs, or 191 metric tons, of carbon dioxide emissions. Similarly equal to removing about 35 cars from the road, saving 21,328 gallons of gasoline, or powering over 100 Santa Barbara-area homes a year (based on a single family occupancy energy use of 5,000 kWh per year). And of course, reducing the City's need for power grid use (and their subsequent power bills)!

The solar power system, spread among the Corporate Yard's roofs, was installed through a partnership of Suntech Power Holdings Co., Ltd and Tioga Energy in which the City of Santa Barbara. The system was installed over a three-month period in the last part of 2008.

Some Ranting on Solar - Alternatives to Photovoltaics

(I posted this in a different forum -- but since it's MY writing, I claim it as my own *grin*)

Solar doesn't always have to be about the "photovoltaics" (although that always seems to be the *sexy* thing that gets the media hype).

Solar mirrors and solar heat have been used long, long, long before the photovoltaics were even invented.

Parabolic solar collectors aimed at water pipes can create a good steam pressure (aka "head") to run turbines to generate electricity... also, the flat-plate mirrors (sun-tracking mirrors called "heliostats") can be focused on salt-containers and heat-exchange units to create thermal heat to run generators. These can be done on a large scale--like the solar-collecting troughs of Solar-1 plant in Nevada, the heliostats of Solar-1 plant near Barstow, California .. .or the large test facility near Albuquerque, New Mexico.

But on a smaller scale, individuals can spray-paint copper-piping with flat-black paint and enclose those pipes into a glass-faced box such that the water flowing through the pipes can either radiate heat into their dwelling or provide hot water for washing.

Yes, we should look into the "industrial-strength-sized" solar concentrating plants for large-scale power generation. But this technology isn't new or even a "breakthrough". This technology (and the underlying concepts) have been used for decades. I'm happy to see that the governments and the research institutions are looking at it again.

Passive solar homes have been around since the 1800's. Tromb walls, clerestory windows, thermal mass, phase-change-materials (PCM), radiative heat exchangers, proper insulation, proper landscaping, -- all of these go a long way to making more energy-efficient homes... but combined with active solar concentrators AND photovoltaics... along with wind and other technologies, you can really squeeze more energy out of highly available sources.

Solar Happenings in the San Francisco Bay Area

Chinese solar photovoltaic manufacturer Trina Solar Ltd. of Changzhou, China, has chosen San Francisco, California as its base for North America sales operations. A few miles south, in the Silicon Valley, the San Jose Tech Museum of Innovation dedicated a 185 kW solar-electric system on the roof of their Parkside Hall--an ancillary building next to their main facility. The solar installation of SunPower solar panels mounted on non-roof-penetrating T10 Solar Roof Tiles was designed and installed by SunPower Corporation.
