Cam and Michelle Mather grow the majority of their own food, plus enough to support a 50-member CSA program. They store enough vegetables in their root cellar, which is a food-storage method that requires no energy input, to enjoy all through Canada’s long winters.

Both idealistic and practical reasons led my wife Michelle and me to choose off-grid living 20 years ago. After a five-year search for rural property, we found 150 acres in the woods of eastern Ontario and struck out in 1998 to build our farm and homestead.

We suffered major sticker shock when our local utility quoted us $100,000 to connect to the electricity grid. Today, we’d be looking at closer to $200,000 to connect. Especially with today’s lower prices for renewable energy and advancements in technology, if I were starting over, I’d still happily make the choice to go off-grid.

Untethered Solar Power

When Michelle and I purchased our 1888 farmhouse, it was powered by eight 60-watt solar panels. We added four 75-watt panels, which were $750 each, or $10 per watt. The following year, we replaced our propane fridge with an electric model and added another four panels. (Today, those panels would cost us one-tenth of what we paid, because the cost has plummeted to about $1 per watt!) My neighbor helped me build and weld my own solar tracker, which allows our solar array to follow the trajectory of the sun across the sky. While solar trackers aren’t necessary, they’ve increased the energy output of our system by about 20 percent.

Several years later, we were offered four 175-watt panels at an excellent price, so I went to work building another solar tracker. For each solar panel we add to our array, life gets noticeably easier because we can use appliances that might have been too energy-intensive for our previous setup. Each addition also allows us to reduce our reliance on propane, which supplements our energy for cooking and heating water. Our arrays now hold 2,300 watts’ worth of solar panels, which is more than sufficient to run a refrigerator, a freezer, two laptop computers, an LCD television and DVD player, satellite TV and Internet, a washing machine, and a kitchen fully stocked with appliances. We get by without air conditioning, which would be a major energy hog. (See “Daily Energy Consumption on the Mather Homestead,” below, for a breakdown of our appliances’ energy use.)
