An On-Grid (or Grid-Tied) Solar System is a solar power setup connected directly to the government electricity grid. It doesn’t require batteries for energy storage. Instead, the system uses solar energy during the day and automatically switches to grid power when needed (like at night or during cloudy hours). With net metering, any extra electricity you produce is fed back into the grid and you receive credits or payments from your electricity provider — making this one of the most cost-effective and smart solar choices.
