Grid-tied solar systems. Grid-tied systems are solar panel installations that are connected to the utility power grid.With a grid-connected system, a home can use the solar energy produced by its solar panels and electricity that comes from the utility grid.. If the solar panels generate more electricity than a home needs, the excess is sent to the grid.
1. Standalone or Off-Grid Systems The off-grid system term states the system not relating to the gird facility. Primarily, the system which is not connected to the main electrical grid is term as off-grid PV system (Weis, 2013). Off-grid system also called standalone system or mini grid which can generate the power and run the appliances by itself.
What Do You Need for an Off-grid Solar Power System? An off-grid solar power system is made up of several key components.
