An ongrid solar system (also called a grid-tied solar system) is the most common type of solar setup used in homes and businesses. It is designed to work along with your existing electricity connection, helping you reduce your monthly power bills.
Unlike battery-based systems, an ongrid system uses the electricity grid as a backup, making it more affordable, efficient, and low-maintenance.
How Does an Ongrid Solar System Work?
The working principle is straightforward:
Step 1 – Solar Panels Generate Power
Solar panels convert sunlight into electricity during the day.
Step 2 – Inverter Converts Electricity
The inverter converts solar electricity into the type of power your appliances use.
Step 3 – Your Home Uses Solar First
Your property consumes solar power before drawing from the grid.
Step 4 – Extra Power Goes to the Grid
If you produce more than you use, surplus electricity is exported.
Step 5 – Net Meter Records Everything
The meter tracks both imported and exported units.
Important Terms Explained
- Solar Panels: Solar panels capture sunlight and turn it into electricity. More sunlight = more power generation.
- Solar Inverter: The inverter is the “brain” of the system. It converts solar power into usable electricity and synchronizes it with the grid.
- Net Meter:
A special meter that measures:
Units you take from the grid
Units you send back to the grid
This ensures you only pay for the difference.
- Grid Synchronization: Your solar system automatically matches the grid’s voltage and frequency, ensuring safe and stable operation.
- No Batteries Required:
In an ongrid system, batteries are not needed because the grid supplies power when solar is not generating (like at night).
This makes the system:
More affordable
More efficient
Easier to maintain
What Happens During a Power Cut?
For safety reasons, ongrid solar systems switch off during grid failure. This protects utility workers repairing power lines.
If backup during outages is important, a hybrid system can be considered.
