Oceana High School in Pacifica, California has become the latest victim of solar theft, a crime that has become more common as the California solar energy industry continues to gain momentum.

The school was just two months away from putting into service a new rooftop solar electric system, worth $43,700, when thieves climbed onto the building’s roof and, according to San Jose Mercury News, made off with 108 solar panels — the first batch that had been installed.

Despite the increase in incidences of solar theft, particularly in Napa and Sonoma counties in California, very few of the thieves have been caught. Last fall, 25 panels worth roughly $30,000 were lifted from a Napa, California winery. And earlier in the year GetSolar ran a post, “Chico, CA: Hotbed of Solar Crime.” Police suspect that stolen panels are sold informally at cheaper rates.

Despite the setback, Oceana High School will continue to pursue its California solar installation. Luckily for school administrators, the solar contractor, Photon, is responsible for any lost or stolen parts of the solar energy system.

This isn’t the first time solar panels have been stolen from a Jefferson District School, which includes Oceana High. In September, about 40 vanished from another site.

The school district is offering an award of $1,000 to anyone who provides information that leads to an arrest.
