There are three types of solar system mostly used in a market. First one is on-grid, the second one is off-grid and the third one is a hybrid solar system. In an on-grid solar system, you don’t need a battery. It is connected with a grid and works with it. It saves power and generates a unit. The second one is off-grid which is used in that place where the power supply problem is faced, so that we get power and backup for the battery. In an off-grid solar system battery is used. The third one is the hybrid solar system. It works on a combination of solar and power if there occurs a problem for a day or two.  In this situation, you can use the grid and bypass it.
