On-grid solar power system is a solar power generation system where it is connected to the utility grid. The electricity produced by the system is routed to the grid from where it is used to run the various appliances. The installation of the same is also fuss-free and easy to maintain.
Off-grid systems work independently of the grid but have batteries which can store the solar power generated by the system. The system usually consists of solar panels, battery, charge controller, grid box, inverter, mounting structure and balance of systems.
A hybrid solar system is grid-tied with battery storage. They come with a special 'smart' inverter that can transmit direct current (DC) power to and from your batteries, and channel alternating current (AC) power between the grid and your home when necessary.
