GRID TIED SYSTEMS

Grid Tied Systems

Grid-tied systems are the most common type of solar PV system. Grid-tied systems are connected to the electrical grid, and allow residents of a building to use solar energy as well as electricity from the grid. Owners of a grid-tied system complete a net metering agreement with their utility. This agreement allows utility customers to receive credit for the excess energy they generate, typically credited as a kilowatt-hour credit on the next month's bill. Net metering policies and agreements are dierent for each utility. Living with a grid-tied solar PV system is no dierent than living with utility electricity, except that some or all of the electricity you use comes from the sun. Grid-tied systems do not provide protection from power outages. When the electrical grid fails, grid-tied systems will not continue to operate. This allows utility employees to fix the power lines safely without wasting time identifying solar energy systems that are still feeding electricity into the power lines.

System components:
  • PV panels (multiple panels make up an array)
  • inverter(s)
  • required electrical safety gear (i.e. fuses, breakers, disconnects)
  • monitoring system to monitor energy production (optional)
