## What is off grid solar energy?

Off-Grid Solar Systems

A stand-alone or off-grid solar system is not connected to the grid but uses a storage battery to store the electricity generated. Your solar panel system will produce more electricity during the day than what your home could consume.

## What is the difference between on grid and off grid solar power?

On-grid means your solar system is tied to your local utility’s GRID. … Being grid-tied is beneficial because you don’t have to buy an expensive battery back-up system to store any excess energy. Being off-grid means you are not connected in any way to your grid’s power system or utility company.

## What is needed for off grid solar system?

For a typical off-grid solar system you need solar panels, charge controller, batteries and an inverter.
