So, what is grid-connected solar?
A grid-connected or grid-tied solar system is connected to the electrical power grid (mains power). Any electricity produced by a grid-connected system but not needed by your house (or solar batteries) is simply exported back to the grid, and purchased by your electricity retailer by the kWh (kilowatt-hour) at a set price (buyback rate).
