Napa Valley is a hot spot for solar panel thieves, but the Sheriff's office is on the case.

The economy may be in the tank but business is booming for solar security companies. A rash of solar panel thefts in the Napa Valley, and elsewhere, have spawned an entire new industry, solar security systems.

It seems that as prices for scrap metal have fallen, thieves have turned their attention to something else popping up in rural areas, solar panels. With more than 34,000 solar installations in California, the state is also reporting the most thefts. Napa Valley is a hot spot because of all the solar systems that have been installed in the past few years. "It is a rural area and these solar arrays are often ground mounted and tucked away in the back of vineyards, it makes them an easy target", says Napa Sheriff Deputy Jon Thompson. The Sheriff's office has been giving wineries safety tips for securing their panels. After being hit twice, Michael Honig of Honig Winery in Rutherford got wise and installed an alarm system. The third time, the thieves got caught in the act. Three local suspects were apprehended.

It is an environmental CSI case of the first order because no one knows where he panels are actually going. In some southern California solar heists, the stolen panels have turned up for sale on Craigslist. But in northern California, the stolen panels have yet to be found. Deepening the mystery, the panels are not likely valuable for their component parts raising the possibility of a black market for panels. There is a lot of speculation where they are going. Some say marijuana growers in Mendocino County are stealing panels to hide their electricity use. Others believe the panels are going off shore. In addition to security, federal legislation may come to the rescue. Congressman Mike Thompson, who represents the Napa Valley, has included a provision against solar thefts in the Solar Technology Roadmap Act. The bill would create a national registry for solar panel serial numbers to try to ‘short circuit' the crooks.

When we started working on this project, we thought it would be easy to find people to interview: D.I.Y.ers with a passion for sustainable building who were testing out new technologies in their backyards. We called consultants, local suppliers, green-minded architects, and collected as many leads as we could. We found a handful of great subjects, but we never quite tapped into that centralized hub we'd envisioned. And that, it turned out, was the point. When you're a D.I.Y.er, you tend to D things Y.

Which is what's so appealing about these projects. Green innovators like those we meet in the radio piece and slideshow are working on their own initiative, spending much more time and money than they would with more conventional technologies, and running a high risk of failure. Ultimately, though, we'll all learn from their mistakes.

Chris Beaudoin fits one type of these backyard innovators: He's a long-time environmentalist willing to spend some extra cash trying out something new. San Francisco's Department of the Environment put Beaudoin in touch with Blue Green Pacific, a local company that will ultimately have two turbines up and running on Beaudoin's garage. So far there are only about five "micro-wind" projects like this in the city, about half of them operational. But stay tuned. Gavin Newsom is encouraging homeowners to experiment with wind turbines, and the state of California is already offering rebates on home turbines.

Dixon Beatty and Stephanie Parrot, who live in West Oakland, fall at the other end of the spectrum, what I'd call extreme do-it-yourselfers (though I'm sure they'll disagree). They've spent years remodeling a beautiful old Victorian in West Oakland that they still call a work-in-progress, despite well-functioning solar thermal and photovoltaic systems that keep the house warm and lit with almost no help from PG&E.

When Lisa and Michael Rubenstein wanted to build their green dream home in Hillsborough they thought they would derive the majority of their energy from photovoltaic rooftop solar panels. PV Panels, afterall, have been the energy technology of choice for eco-friendly buildings. But as the Rubensteins waded further into construction, their architect suggested a geothermal heating cooling system. They were told geothermal can provide the most energy efficient, environmentally friendly home and so, they decided to go for it. Together, with PV solar and solar thermal panels, the Rubenstein's monthly energy bill is only eight dollars. Not bad for a 6,000 sq. foot home. It was an expensive project but what they have created is an experimental, contemporary home that gives living green a whole new aesthetic.

Also merging modern design with eco-practical, is Sunset Magazine's idea house for 2007. PIX Located in San Francisco's Mission District, Casa Verde is Sunset's first idea house to be focused in an urban setting, The model home features solar and wind power, a green roof and a sleek, eco-friendly aesthetic.

7/23/08 UPDATE: The contentious battle between solar energy and redwood trees has come to an end. Governor Arnold Schwarzenegger has signed a bill into law that guarantees if California property owners plant a tree before a neighbor installs solar panels the neighbor can't require the tree to be chopped down, or trimmed, if it is shading their solar panels. Check out this article in the San Jose Mercury News.
