An on-grid solar system is an electrical generator using solar energy, a non-conventional source of energy. In contrast with off-grid systems, grid-tied systems are connected to the grid. As a consequence, the not used generated power of the system can be sold to the electrical company. In addition, the user can buy energy from the grid if needed.
