An off grid comfortable modern dwelling using solar to provide as much of the energy for the house as economically feasible.

We had originally intended to use solar just for heating and domestic hot water, but we discovered that connection to the grid would involve high cost, tree cutting, and issues with neighbours. As Solar NS members we knew that living off grid was possible and we proceeded to do exactly that. We sidestepped the need for Nova Scotia Power, and have lived happily ever after.

What would we do different?

We tried to use the propane stove for a hot water backup heater. The effort was a failure because we could not transfer enough heat to thermo-siphon water to a hot water tank.
