On-grid solar power systems generate power using a solar power system and are directly connected to the utility power grid.These systems send excess power generated by the solar power system to the utility grid and consumers get compensated for the extra power fed back. These systems work in collaboration with the power grid. In the case when there is not enough sunlight to meet your business’ needs, the system runs on the power supplied by the grid. These systems are best suitable when your power consumption is high and you wish to reduce your electricity bills. These system do not work during the power outage.
