Net Metered Solar Connection

The term “net metered” refers to the way your solar power system is connected to the electrical grid.
Cables from the solar array are connected to the electrical service panel in your home. That way, the solar electricity is first offered to the home and if the home doesn’t need the power it flows through the bi-directional meter to the electrical grid.
Bi-directional electrical meters measure flows of electricity to and from the grid and your Hydro company reconciles these flows monthly. Credits are carried forward for 12 months when they are reset to zero. You pay monthly bill based on your usage minus credits for electricity generated by your solar array. Obviously, it doesn’t pay to produce more than you use over a 12 month period as the excess is gifted to your utility.
Because the “smart” meter is replaced by a bi-directional meter in Ontario, your billing is based on tiered rates instead of time of use rates. One great advantage is that you no longer need to worry about “peak” rates-running a  dishwasher or washing machine at noon on a workday costs no more that week-ends or nighttime. And because the electricity you generate will reduce your overall consumption, most of your billings will be at tier 1 rates which are lower than tier 2. Ideally, the only charges would be minimums to remain connected to the grid.
