Our Eco House - the Inner Workings
We produce most of our electricity from the 1740Watts of solar panels. During the day when we are producing more than we need the “green” energy flows out to the grid. At night when we are using more than we are producing we use energy from the grid. The dual meter tracks both inputs and outputs and we pay the difference. Our hydro bills average about $30 a month, most of which is service charges. We have an integrated battery backup which allows us to still have power in the event of a blackout for all critical appliances.
The average Canadian home uses 35Kw per day of electricity – we use between 5-10Kw – all CFL’s, Energystar appliances, 3 computers, two televisions, DVD players all on power bar. We have no dishwasher, clothes dryer, air conditioner.
The metal roof allows us to collect cleaner rainwater into the rain barrels and we also have the ability, should it be required, to direct one of the downspouts into the cistern.
