On-Grid Solar System in Chennai
Switch to a grid connected solar system that’s built for real EB savings. An on-grid solar system is connected to EB—it powers your daytime loads using solar and exports surplus electricity through approved metering (net meter for homes). Since it’s a solar power system without battery, it’s usually the most cost-effective way to reduce EB bills long term.Synergy Automatics is specialist in on-grid solar system in Chennai based on your EB bill pattern, roof space, shading, and safety requirements—so the output estimate and savings expectations stay practical, not exaggerated.
What Is an EB Connected Solar System?
An on-grid solar system works along with EB power. Solar energy is used first during the day, and any excess is sent to the grid. When solar power is not available, electricity is drawn automatically from EB—without any manual switching.In simple terms, it is solar power with EB connection—a solar power connected to electricity board supply that automatically balances between solar generation and EB usage.
Components in an On-Grid Solar Power System
- Significant reduction in EB electricity bills
- No battery purchase or battery maintenance (battery-free system)
- Simple, reliable day-to-day operation
- Long operational life with correct installation
- Faster ROI compared to battery systems (depends on usage & tariff)
- Environment-friendly power generation
How an On-Grid Solar System Works
- Solar panels generate DC electricity from sunlight
- Grid-tied inverter converts DC to usable AC power
- Your loads consume solar power first (daytime)
- Excess solar is exported to EB through the meter
- EB supplies power when solar generation is low or unavailable
Everything works automatically—no manual changeover.
Benefits of On-Grid Solar in Chennai
- Solar PV panels
- Grid-connected (on-grid) inverter
- Net meter / Net feed meter (as applicable)
- Mounting structure
- AC & DC distribution panels
- Earthing and lightning protection (as applicable)
- Necessary isolators and protection devices (as applicable)
Net Meter / Net Feed Meter Approval Process (TANGEDCO)
A correct process matters because this is a solar power connected to electricity board. Typical steps include:
- Site feasibility + load review
- Application submission (as applicable)
- Required drawings/documents submission
- EB inspection and verification
- Net meter / net feed meter installation
- Grid synchronization and commissioning
Applications of On-Grid Solar in Chennai
Homes – Net Meter Savings You Can Track
A home solar system connected to EB with a net meter reduces your EB bill by adjusting exported solar units against imported units (units-to-units). It’s the simplest solar power system without battery and the most common bill-saving approach. Settlement-period rules apply for any remaining surplus at year-end as per TNERC net metering provisions.
Commercial & Industrial – Net Feed (Bill-to-Bill) for High EB Consumers
For commercial and industrial consumers, the same solar power with EB connection typically works under net feed / net billing, where exported solar is credited by value and adjusted against the bill amount. Carry-forward and settlement/payment options at period end are handled as per TNERC orders. Ideal for schools, office, malls, hospitals, factory.Large systems (25 kW–1 MW+) can be planned as an on-grid solar plant for own use or through a third-party model where you pay for solar via a commercial agreement instead of owning the system.
Subsidy for On-Grid Solar in Chennai
Residential only (subsidy capped up to 3 kW)
For domestic/residential customers, the central subsidy under PM Surya Ghar is available only for residential grid-connected rooftop/on-grid systems, and the subsidy benefit is capped at 3 kW (maximum benefit up to ₹78,000, subject to scheme rules and DISCOM approval).
Commercial & Industrial (no subsidy)
For commercial and industrial consumers, there is no central subsidy under the residential CFA/subsidy programme. These systems are typically installed on a non-subsidy basis and the benefit comes from EB bill savings (and tax/accounting benefits where applicable).

FAQs – On-Grid Solar System in Chennai
1) Is on-grid solar the same as a solar system connected to EB?
Yes. People commonly call it a solar system connected to EB or solar power with EB connection because it operates in sync with the electricity board supply.
2) Does an on-grid solar power system need a battery?
No. An on-grid setup is a solar power system without battery. That’s why it’s usually more cost-effective and easier to maintain compared to battery-based systems.
3) If I export extra solar units to EB, will I get them back?
For residential net metering, exported units are generally credited and adjusted unit-to-unit against EB import within the settlement period. If surplus remains, it is carried forward and settled at the end of the settlement/financial year as per TANGEDCO/TNERC rules.
4) Will on-grid solar work during a power cut?
No. For safety, a grid connected solar system shuts down during EB outages to prevent back-feeding into the grid. If you need backup, you’ll need a hybrid/backup solution.
5) How much roof area is needed for an on-grid solar system?
It depends on panel wattage and layout. The key requirement is usable shade-free space. We confirm exact space during the site visit after checking shadows and placement feasibility.
6) Is there a subsidy for on-grid solar in Chennai?
- Residential: Subsidy is applicable only for residential systems and the benefit is capped up to 3 kW (as per scheme limits and eligibility).
- Commercial/Industrial: No subsidy for commercial or industrial on-grid solar.
7) Can I expand my on-grid solar system later?
Often yes—depending on inverter capacity, EB limits/sanctioned load, and available space. We can plan “expand-ready” systems if you expect growth.
