Why is off-grid solar better than grid-tied solar?

As opposed to grid-tied solar, off-grid solar lacks the ability to tap into the grid for energy if needed. When cloudy weather persists, there is a chance that you will use all of your stored energy. With an off-grid system, power would not be available until the solar system has a chance to replenish itself.

What are the disadvantages of an off-grid Solar System?

Many people just leave it due to the high initial cost. Another disadvantage of an off-grid solar system is that you don't have enough amount of electricity storage because your batteries can store a limited amount of electricity and you can't use it freely. You should have to be more careful in using electricity as compared to a grid system.
