What Components do I Need for a Grid-Tie Solar Electric System?

A basic overview of the components needed for an utility grid-connected system.

Grid-tie systems are inherently simpler than both grid-tie systems with battery backup and stand-alone solar systems (off-grid solar systems).

In fact, the main differences are basically:

A grid-tie system is essentially just solar modules and a grid-tie inverter!

Today’s sophisticated grid-tie inverters incorporate most of the components needed to convert the direct current from the modules to alternating current, track the maximum power point of the modules to operate the system at peak efficiencies and terminate the grid connection if grid power is interrupted from the utility.
