Grid-Tie System

Grid-tie systems generate electricity, sending this energy back to your utility company's power grid. In effect, this means the utility company will be paying you to produce energy for them, since the energy you produce counts against the energy your home or business uses.

Your solar panels will produce DC (Direct Current) electricity. This electricity will be run through an inverter to produce AC (Alternating Current) electricity. This energy is then run into your AC power panel, which feeds energy back to your utility companies power grid. If your solar power array produced enough electricity, your utility meter would begin to run backward!

The major components for grid-tie systems are:

• Solar PV panels - they convert energy from the sun into DC power, mainly 12V and 24V. The system size installed is depended upon the number and size of panel/modules.

• Combiner Box - This combines all the solar panel connections.

• DC Breaker Box - Your array's breaker safely shuts down your solar power system at a moment's notice, allowing for safe maintenance, repair, and inspection.

• Inverter - this unit converts DC power to AC power (120V, 230V, 400V etc) so that AC appliances can run. Most home appliances use AC power to operate. Note that a grid-tie system uses a special inverter than can be connected to the utility line.

• Grid Disconnect - A grid disconnect allows you to stop the flow of electricity between your solar power system and your electrical system. This provides for the safe maintenance of electrical and utility systems.

• Other components include panel mounting frames, lightning protection  and others.
