The Basic Off-Grid System. The biggest difference between grid-connected and off-grid solar installations is where the electricity goes. All the different components of the two systems revolve around this. All solar installations use solar panels to harvest sunlight to create electricity. Solar panels create direct current (DC) electricity.
