The difference between energy storage and grid connection

What is the difference between a grid-tied solar system and battery storage?

Grid-tied systems feed excess solar energy back to the utility company, offsetting electric bills. Battery storage – or an off-grid solar system – provides true energy independence by retaining solar energy in batteries for use anytime. With the grid, you avoid big upfront battery costs but remain dependent on unsteady utility pricing and power.

Are grid-tied solar systems better than off-grid solar?

Unlike off-grid solar systems that operate independently, grid-tied systems rely on the grid for supplemental power. Overall, grid-connected systems provide an affordable way to harness solar power while maintaining convenient access to the grid when needed. However, reliance on the grid can result in a need for more energy independence.

Why should you use a grid-connected system?

With grid connection, you avoid that steep battery cost by simply feeding excess power back to the grid. But you still depend on the grid for supplemental electricity when your panels underproduce. Grid-connected systems provide convenience and integrate seamlessly with your existing on-grid setup.

What happens to excess electricity in a grid-tied system?

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.

How does a grid-connected solar system work?

With a grid-connected solar system, your solar panels link to the existing electricity grid to send excess solar power back into the grid. This allows you to get credit or payment for the excess solar energy you produce.

What is the difference between grid-tied solar and hybrid solar?

While grid-tied solar offers convenience and batteries provide energy independence, hybrid systems strike a balance using both solar storage and grid connection. With a hybrid PV system, batteries can store solar energy to power electrical appliances and devices during grid outages.
