This system works two-ways – the supply of electricity can flow from the grid to which it is connected to the user’s home and from the user’s home to the grid. This feature makes the on-grid solar system affordable and highly useful. The solar panels, installed on the user’s home are ‘tied’ to the grid. These panels generate electricity when the sun is shining brightly and this electricity is then ‘sent’ to the electrical distribution panel in the home for use.
The off-grid solar system is not connected to the power grid but instead the energy produced during the day from the sun’s rays, is stored in batteries. This system is efficient for those homes that cannot have access to the electricity produced by the grid and is therefore completely independent of it. The power stored in the batteries is used by homes at night and at other times when the solar panels are unable to generate as much electricity as is required.
The main difference between the hybrid solar system and others is that it has both battery backup and connection to the grid. This system is high on dependability since there is a constant electricity supply to the home. The ability to store the solar electricity in batteries for use at any time, without the need to draw on the electricity generated by the grid greatly reduces electricity costs for the home.
