Grid-tie system is a power generating facility built on any building or land which is connected directly to the electric grid. Electricity from the Solar PV array is fed into the power grid and the utility meter records the power fed to grid as a credit.

The illustration shows how a typical Solar PV Grid-tie system is configured to send power to the grid.

When the Sun Shines, the Solar PV array silently generates DC electricity. The Inverter in the system converts that DC electricity into AC electricity. The AC electricity is finally fed into the Grid via Energy Meter. This happens throughout the life of the system whenever there is Sun.

Components of a Grid-tie System consist of Solar PV modules, Inverter, safety devices, control panel, cables etc.

As a Ontario Home / Commercial Building / Land owner you consider installing a Grid-tie Solar PV system because:

• under the FIT program, the Govt. of Ontario through OPA will pay you for Electricity delivered from your generating facility at a premium rate for a 20-year period. So by installing a system your earning is guaranteed for a long time.
• the system increases your property value as a source of earning over longer period.
• you are a part of Green House Gas reduction movement by producing green energy.
