Reduce EB Bill through Net Metering
Reduce EB Bill through Net Metering
On-grid solar systems are connected directly to the electricity board (EB) grid. You generate solar power during the day and export excess power back to the grid through net metering.
- No batteries required.
- Lower investment. Faster payback.
How On-Grid Solar Works
How On-Grid Solar Works
Solar Panels → Grid-Tie Inverter → Net Meter → EB Grid → Load
Daytime solar power runs your loads
Extra power goes to EB grid
EB adjusts units in monthly bill
Night-time power comes from EB as usual

Example (5 kW Residential System – Tamil Nadu)
Example (5 kW Residential System – Tamil Nadu)
- Average monthly EB bill: ₹5,000–₹8,000
- Annual consumption: ~7,000 units
- Solar generation: ~7,500 units/year
- Net savings: 70–90% reduction in EB bill
- Average monthly EB bill: ₹5,000–₹8,000
- Annual consumption: ~7,000 units
- Solar generation: ~7,500 units/year
- Net savings: 70–90% reduction in EB bill
- 3–5 Years (depending on usage & subsidy)
- After that → 15–20 years of near-free electricity.

Bank Loan Possibilities
Many banks support rooftop solar financing:
Available Options:
SBI Green Loan
Nationalized banks
Private banks
NBFC solar financing
7–10 years tenure
8%–11% interest (varies)
EMI often less than EB savings
Example:
If EMI = ₹4,500/month
And EB saving = ₹6,000/month
You still save ₹1,500/month.
After loan closure → full savings.
