BEFORE & AFTER: EB Bill Reduction Using Solar
This is the most important part for factory owners.
Let’s compare actual impact.
BEFORE Solar Installation
| Component | Amount |
|---|---|
| Monthly Consumption | 40,000 units |
| Tariff | ₹8.5 per unit |
| Monthly EB Bill | ₹3.4 Lakhs |
| Annual EB Bill | ₹40 Lakhs |
| Demand Charges | High |
| Tariff Escalation Risk | High |
| Long-Term Stability | Low |
Factory was fully dependent on grid electricity.
AFTER Factory Rooftop Solar in Tamil Nadu
Solar Capacity: 200 kW
Annual Solar Generation: ~3,00,000 units
| Component | After Solar |
|---|---|
| Grid Units Reduced | ~60% daytime |
| Annual Solar Savings | ₹25 Lakhs |
| EB Bill Reduction | ~45% |
| Payback Period | 3–4 Years |
| Long-Term Savings (25 Years) | Multiple Crores |
| Energy Stability | High |
EB Bill Reduction Summary
Before Solar → ₹40 Lakhs per year
After Solar → Reduced by ₹25 Lakhs
Net Electricity Cost Pressure reduced significantly.
This clearly demonstrates the financial strength of Factory Rooftop Solar in Tamil Nadu.
Solar Payback Period for Industries
Annual savings: ₹25 Lakhs
Estimated payback period: 3–4 years
After payback:
Savings continue for 20+ years.
Industrial Solar ROI remains strong even after considering Solar Maintenance Cost for Industrial Plants.
Demand Charge Reduction with Solar
Before solar:
High kVA demand during production hours.
After solar:
✔ Reduced daytime grid dependency
✔ Lower kVA draw
✔ Better electricity cost control
Solar improves overall industrial energy cost optimization.
Net Metering Policy in Tamil Nadu for Businesses – Role in Savings
Under Net Metering Tamil Nadu framework:
Excess units exported were adjusted.
This improved:
✔ Savings predictability
✔ ROI stability
✔ Payback accuracy
Without net metering, EB bill reduction would be different.
Solar Maintenance Cost for Industrial Plants
Maintenance included:
✔ Periodic panel cleaning
✔ Inverter inspection
✔ Performance monitoring
✔ AMC support
Even after maintenance cost, Industrial Solar ROI Tamil Nadu remained strong.
Maintenance protects long-term savings.
Industrial Solar Plant Cost Tamil Nadu – Strategic Investment
Instead of asking:
“How much does solar cost?”
Factories should ask:
“How much will we lose by not installing solar?”
If tariff increases ₹1.5 per unit:
Additional annual cost ≈ ₹7 Lakhs
5-year impact ≈ ₹35 Lakhs
Delay increases opportunity cost.
