Marin Sanitary Service Goes Solar

Joe Garbarino, President Marin Sanitary says, "I've been a garbage man since 1948 in high school, but I was never really a garbage man, I was a scavenger. Now we're scavenging the sun -- we're recycling it." "The more of this we can do, the less we're going to depend on foreign oil, and that's hurting the US economy really bad, and it's getting worse every day." "We're leasing the solar panels and the cost is less than what our yearly energy bill would be."

Hotel Carlton, San Francisco: This Joie de Vivre Hotel uses green design to energize its roof line and its bottom line.

Making the shift to solar may be primarily about energy savings, but it also has aesthetic and infrastructural implications. Sunlight Electric, a locally based designer and retailer of photovoltaic systems, took that into consideration when mapping out the installation for this Joie de Vivre Hotels' property on Lower Nob Hill. After a system analysis, Sunlight Electric decided on a ballasted racking system for the 105 panels that would sit atop the Hotel Carlton: The panels don't penetrate the roof, so they're modular and can be moved if necessary (if the hotel decided to add floors, for instance).

Wineries Celebrate Solar Power

Rob Erlichman, CEO of Sunlight Electric, citing stats from the NorCal Solar Energy Association, said that across the Bay Area's 10 counties, the average watts per capita of installed solar is 16.7; but, Napa County far exceeds that at 51.1 watts per capita. Erlichman's research also shows "Rutherford is the most solar place in all the Bay Area."

"With a population of 525, that means our work has generated 1,135 watts per capita, so it seems that our customers are largely responsible for putting Rutherford on the solar map."

Sunlight Electric has completed five major projects in Rutherford — Frog's Leap, Honig, Long Meadow Ranch, Staglin and ZD Wines, totaling about 600 kilowatts.

Going Green at Frog's Leap

On sunny days Frog's Leap produces more energy than it needs. "That energy goes back through our meter, runs our meter backwards, and gives our neighbors the electricity that we're producing, or sells it to them," says founder John Williams. "On the days that we can't produce enough energy, or at night, that energy comes back through the grid and runs our meter forwards." And as a result Frog's Leap's electricity bills are a lot less these days. "Our first year I think our energy bill for the whole year was $1.58, or something like that," says Williams.

California Wineries Going Solar

The sun that ripens the grapes is also providing power for a growing number of California wineries, including Robert Mondavi vineyards. Sunlight Electric has installed 1,000 200 watt solar panels at Staglin Winery in Napa Valley at a cost of $1 million, reports ABC News. The panels produce almost enough power to meet all the small winery's energy needs. The vineyard hopes to recover the cost of the panels within 15 years through a combination of savings on electricity costs, state subsidies, federal tax breaks, and cash incentives from Pacific Gas & Electric.

Cover Story: How Solar Investments Are Paying Off

Oftentimes, a winery's decision to go solar leads it to evaluate its resources on a broader scale. "After talking to other wineries that have gone solar, we decided we wanted to be a member of that group, not unlike those who now drive hybrid cars," said Jay Schuppert, president of Napa Valley's Cuvaison Estate Wines (60,000 cases). He said their solar install galvanized them to review all of their practices and their use of energy, water and other resources. Flipping the switch on their new system, noted Schuppert, has already been met with enthusiasm from distributors, trade and consumers.

Havens Wine Cellars, which produces about 18,000 cases of wine annually, recently purchased a 46.5 kW system (installed by Sunlight); they anticipate that it will save them around $14,000 a year. The winery will have a net expense of 26 percent of the project's total cost after rebates and other subsidies. The system will pay for itself in a little over six years and will earn a 17 percent internal rate of return.

"We use quite a bit of electricity at the winery, especially during harvest: cooling the barrel cellar, fermenting musts and running equipment," said Michael Havens, founder of Havens Wine Cellars. "The energy that we once spent thousands of dollars on each month is now being generated on our south-facing roof." The system will reduce the winery's carbon footprint by more than 87,000 pounds of CO2 annually, which is equivalent to the carbon captured annually by 12 acres of forest.

Wineries Sizzle with Solar Power

Cuvaison Estate Wines in Napa is taking advantage of state incentives that will return a full two-thirds of the initial cost over a four-year period. Additionally, those panels will provide a minimum of 95 percent of the winery's electricity – eliminating PG&E bills that were running to $72,000 a year, according to President Jay Schuppert.

Cover Story: Sensible Solar: Why small wineries invest in sustainable energy

Keenan--set on a 100-year-old, thickly forested property purchased by Michael Keenan's late father, Robert, in 1974--was not built with solar in mind, and the winery faced special challenges. Keenan interviewed two vendors, and chose San Francisco's Sunlight Electric (, in large part because of its unique proposal to mount 10 panels each on 29 poles at the end of vine rows. Inverters, which convert DC to AC power, are located on every fourth pole, Keenan explained, a crucial consideration, since DC current rapidly loses strength the farther it travels.

"We wanted to generate our own power; not use so much fossil fuel, and devote more of our resources to making great wine," Brandon Staglin said. Upon Honig's recommendation, Sunlight Electric was chosen to install a system that will accommodate expected growth over the next five years. With 30% extra capacity, Staglin's first monthly power bill zeroed out, supplying more energy than needed for the winery's current production.

Green Beat: Napa Valley Wineries Going Solar

Concern for the environment and jumbo PG&E bills prompted Saintsbury to invest more than a half a million dollars in the solar project.

"We have a $30,000 to $40,000 utility bill every year. That's doing everything from pumping water out of the well to running the equipment that we use, says Dick Graves, president of Saintsbury Winery.

During the day when the solar panels collect the most sunlight and the winery is in full operation, the panels provide all the power Saintsbury needs.

"The whole agricultural sector is looking at its climate impact," said Graves.
