An off-grid solar system permits electricity to be harnessed by solar panels and stored inside a battery without direct connection to the utility grid, providing an independent power supply to your home or business.
Basically, an off-grid solar system is a novel innovation which provides you independent energy harnessed by the sun. An off-grid solar system is made up of the following components.
