On-Grid Or Grid-Connected Roof-top system is a solar power system which is connected to the utility grid. These are mostly used in utility scale projects to supply electricity to the grid/DISCOM at pre-determined tariffs and are most suitable for areas where there are no or less power cuts and the customer pays high electricity tariffs. They can be easily synchronized with Diesel gensets to reduce the overall cost of electricity/unit and also allows system to avoid storage (batteries), which has a huge cost. It is specially helpful in case of insufficient solar power, as it switches to the grid for non-stop power supply.
