PIPE DREAM, SAY LOCAL AUTHORITIES; 'TREND' NOT LIKELY TO GROW ON NORTH COAST Law enforcement around the country report that illegal marijuana growers are turning to solar panels to power indoor lights. New Mexico state police recently busted a marijuana operation around the Four Corners region that used solar panels to pump water, according to the Associated Press, and authorities in California have stepped up enforcement against solar panel thefts from vineyards that they believe were headed to illegal growers. On the North Coast, however, authorities say that solar-powered pot grows wouldn't make sense. "They'd have to cover a mountainside," Eureka Police Chief Murl Harpham said. "PG&E is the cheapest power you can get." While Harpham has an array of solar panels on his own mountain cabin that powers lights and appliances, the amount of energy needed to grow marijuana indoors under halide lights far exceeds the generating power of a few panels, and local law enforcement officials say they've never seen solar power used for indoor grows. It's expensive to install, inefficient for growers' needs and doesn't provide much protection from nosy cops. Humboldt County Sheriff's Office Sgt. Steve Quenell has only seen solar power used to power fans -- "a few arrays here and there, typically on the large greenhouses." Quenell said those sophisticated grows likely only use solar because they are off the grid, and agreed that solar panels could not provide the extreme amount of energy -- a "crapton," by Quenell's estimate -- that grow lights need. In the North Coast's towns and cities, some growers might see logic in using solar panels on residential houses to conceal high energy use, which could potentially tip off police to an indoor grow, Harpham said. But according to Pacific Gas and Electric Co. spokeswoman Brittany McKannay, PG&E doesn't just hand out energy usage statistics for houses. "Confidentiality to our customers is something we take seriously." McKannay said. While PG&E investigates energy theft and other issues, by the time it hands over records sought by subpoenas or search warrants, law enforcement is already in the process of investigating a suspected marijuana grow. PG&E officials have said they are uncomfortable with their employees being made to look like enforcers, which could lead to confrontations with nervous marijuana growers. "When it comes to just usage, that's not something we're monitoring," McKannay said. The Associated Press reported last month that marijuana growers elsewhere, in an attempt to avoid detection, have turned to solar power. During last month's bust in New Mexico, agents raided a solar-operated facility and seized around 250 marijuana plants that were between six- to eight-feet tall in an isolated area of Rio Arriba County. In 2010, police in Socorro, N.M., pulled more than 1,500 plants from three locations in a marijuana operation that detectives called "very elaborate and sophisticated." Police said the operation used solar panels, water pumps, batteries and hundreds of yards of hose that functioned on timers. The use of expensive solar panels allows illegal marijuana operations avoid the need for massive power consumption from nearby power companies, tipping off local and federal authorities, investigators say. Solar power works in two ways: Energy gathered from the panels can be stored in batteries, or the panels can be wired to an existing utility grid. Most residential solar panels are wired to feed into the grid. This saves a homeowner from purchasing expensive batteries and can make the homeowner a bit of money if they end up providing more power to the grid than they use. At the very least, the homeowner's electricity bill drops. Arcata Mayor Michael Winkler said he hasn't heard of solar panels being used in grow houses busted by Arcata Police. "I just don't see that there's any practicality at all," he said. "It might be a gesture on the part of a grower to put up panels but doesn't make much sense." Winkler, who is an energy consultant by trade, said 97 percent of a sun ray's energy would be lost in converting sunlight to grow light. "It's so interruptive in getting lights to the plants," he said. "It's like having a three percent skylight." Anthony Silvaggio, a Humboldt State University sociology professor and member of the Humboldt Institute for Interdisciplinary Marijuana Research, said solar powered grows don't add up financially or ecologically. "I don't think that's gonna be a trend anytime soon," he said. "The amount of space you'd need to power an industrial grow -- you'd need an acre. It'd be ridiculous." Solar panel construction and the deforestation required to put in a sufficient number of panels would make solar growing ecologically unfriendly. "It's not an appropriate use of the technology because you can grow it in the sun," Silvaggio said. Arcata voted a law into effect this year that will tax residents who exceed a PG&E electricity usage baseline. Under the measure, high usage households that exceed the baseline by 600 percent would be charged an additional 45 percent of the electricity portion of a bill. While the tax was designed to discourage residential grow houses -- as well as legal high energy users -- Winkler doesn't think that growers will rush to build solar arrays in order to slip under the tax threshold. "What would make more sense for them would be to switch to higher efficiency lights," he said. Silvaggio said that even indoor growers looking at solar to shave a little money off of their monthly bill is unlikely. A solar setup costs $25,000 -- more if it's installed by a black market electrician -- and takes five years to pay for itself, Silvaggio said. That's a big investment for a business that could be shut down by police at any moment. McKannay said that state utility regulations would also discourage solar powered grows. Solar panel arrays must be set up according to a residence's historic usage so that a customer can lower their bill but not necessarily make scads of money selling power to a utility, McKannay said. That invites a round of inspections that growers aren't likely to invite upon themselves, Silvaggio said. "There's a whole sort of slew of procedural things that happen," he said. And while law enforcement in sun-rich areas like New Mexico may herald a burgeoning trend, that's not something that's been seen on the North Coast, or is likely to be, Silvaggio said. "When you're looking at marijuana production, it doesn't make sense to do it like that," he said. - --- MAP posted-by: Jo-D
