Solar power systems for house roofs
Grid-tied is also referred to as grid interactive or utility interconnected. What this means basically is that if your utility allows it, your system would be connected through your meter to the electric grid.
A grid-tied system is made up of solar panels, a grid tie inverter, and other electrical components. This is the least expensive and most logical choice if you live in an area which is serviced by the utilities. Since the power is not stored in batteries, there are no batteries to replace. However, this type of system provides no back-up power in case of power failure.
If you are producing more power than you are using, the electric meter will spin backwards which means you are producing excess electricity which is then being fed back into the grid.
