How Net-Metered Solar Works

Net-metering allows you to produce more power than you need at a given moment and send the excess back to the grid. The diagram shows how net-metered solar works on a grid-tied solar system. For a more detailed explanationof the benefits, see Net-Metering or call us at 802-728-3600.

  • Solar Photovoltaic (PV) Array creates direct current (DC) electricity.
  • The Inverter changes the DC power to alternating Current (AC), which is what the utility is supplying to the house.
  • The Net Meter connects you to the utility grid. The solar electric system’s size is measured in kilowatts (kW) DC.
  • A typical size is a 5-6kW with approximately 20-24 solar panels.
  • A system’s production is measured in kilowatt hours (kWh), and in our region a 5kW system produces between 5000 – 6000 kWh’s per year.
  • The energy you produce with your Solar PV installation offsets your utility use, and you are paid a retail rate for your power.
  • Some utilities have additional incentives for adding solar electricity to your home, farm or business (i.e. Green Mountain Power). Contact us for more information at 802-728-3600 or info@new.catamountsolar.com
