Solar to Go
A Mobile Solar Generator Makes Going Off-Grid a Little Easier

John and Victoria Mc-Bride fell in love with their 100-acre California ranch the minute they set eyes on it. The property, located in the hills of northern San Luis Obispo County’s wine country, had a stunning view overlooking Santa Margarita Lake. Signs of wildlife—eagles, mountain lions, bears, coyotes and foxes—were everywhere. There was even room for a corral big enough to hold their dozen or so horses. The land had everything they ever wanted—except electricity.
Undeterred by the hardships of rustic living, the McBride’s bought their dream property and set up a modest shelter where they could spend weekends taking family and friends on remote horseback adventures. Their power needs were met by a gas generator and a wood-burning stove. But after six years spent hauling gas fuel from a distant town, the relationship with their noisy, belching generator went sour. Alternative options were limited. The price tag for extending power lines a half mile up the road to their property was set at $50,000.
The McBride’s began to wonder if there were other off-grid solutions that could meet their power needs. During a trip to the county fair, they happened across a booth run by Travis Semmes, a young conservationist and solar entrepreneur. Semmes showed them his portable mobile solar trailer, a device born from an idea he had while working with his father, a contractor who builds solar homes. The McBrides and Semmes struck up a conversation that turned into a friendship. A few months later, Semmes drove one of his brand-new units onto the ranch—a trailer with batteries and inverter inside. He disconnected the McBride’s sputtering old diesel generator, flipped up the solar panels on the trailer, connected some wires to the house, and the McBrides began a new relationship with the sun.
Because the couple lives modestly, they have more than enough electricity to run their kitchen appliances, space heater, lights, stereo, computer and wide-screen television. A wood-burning stove gets them through the coldest nights of the year. Their gas generator has only been used once in two years.
Semmes’ company, Mobile Solar Power, provided the first maintenance lesson: filling the batteries with water once a month, cleaning the solar panels during the hot, dusty summer months and equalizing the batteries twice a year. Semmes says the upkeep is relatively simple, but it’s not for everyone. “If you don’t remember to put air in your tires or add oil to an engine,” he says, “you probably shouldn’t buy one of our units.”
John McBride estimates it will take about a decade to recover his costs. In 15 years, it will be time to think about replacing the large 24-volt, 1,640-amp-hour battery bank, at a cost of roughly $7,000.
“We don’t mind a rustic life; it allows us not to be dependent on anyone,” he says. “I highly recommend the solar generator for anyone who lives out in the middle of nowhere. If we ever move, we can take the unit with us. We wanted to go solar because we like peace and quiet. And when everyone in town is losing their power in storms, we don’t.”
