Imagine this.
Your rooftop solar system generates electricity from 8 AM to 4 PM.
But nobody is at home.
Your children are at school.
You are at work.
Your air conditioners are off.
Your appliances are barely running.
So what happens to all the electricity your solar panels generate?
This is where net metering becomes one of the most valuable benefits of rooftop solar.
Without net metering, a significant portion of your solar generation may not be fully utilized.
With net metering, excess electricity can be exported to the electricity grid and accounted for through a bidirectional meter.
For homeowners across West Bengal, net metering is one of the key reasons rooftop solar has become financially attractive.
What Is Net Metering?
Net metering is a system that allows electricity generated by your rooftop solar system to flow to and from the electricity grid.
A special bidirectional meter records:
✓ Electricity Imported
✓ Electricity Exported
This enables homeowners to utilize solar energy more effectively throughout the year.
Why Net Metering Changes Everything
Most homeowners think solar only works when they are using electricity.
That is incorrect.
A rooftop solar system often generates the highest amount of electricity during the daytime.
Exactly when many homeowners are away from home.
Net metering allows this surplus electricity to be exported rather than wasted.
This is why net metering dramatically improves the value of rooftop solar.
How Net Metering Works
Morning
Solar begins generating electricity.
Your home consumes solar power first.
Afternoon
Solar generation exceeds household demand.
Surplus electricity is exported.
Evening
Solar generation stops.
Your home imports electricity as required.
Throughout The Year
The net meter records:
- Import Units
- Export Units
creating an accurate record of energy flow.
Example: 3 kW Solar System With Net Metering
Monthly Consumption:
300 Units
Recommended Solar Capacity:
3 kW
Annual Generation:
3900–4350 Units
Many homeowners find that a substantial portion of annual consumption can be offset through properly designed rooftop solar systems combined with net metering.
Example: 5 kW Solar System With Net Metering
Monthly Consumption:
500 Units
Recommended Solar Capacity:
5 kW
Annual Generation:
6500–7250 Units
Suitable for:
- Air Conditioners
- Larger Families
- Higher Electricity Usage
Example: 10 kW Solar System With Net Metering
Monthly Consumption:
1000 Units
Recommended Solar Capacity:
10 kW
Annual Generation:
13000–14500 Units
Ideal for:
- Villas
- Luxury Homes
- Premium Residences

What Is The Difference Between A Normal Meter And A Net Meter?
| Feature | Normal Meter | Net Meter |
| Records Consumption | Yes | Yes |
| Records Export | No | Yes |
| Two-Way Energy Flow | No | Yes |
| Suitable For Solar | Limited | Yes |
Net Metering Vs Gross Metering
Many homeowners confuse these terms.
Net Metering
Electricity is first consumed within the home.
Surplus electricity is exported.
Gross Metering
Electricity generated is measured separately according to applicable utility policies.
For most residential consumers, net metering is the commonly discussed mechanism associated with rooftop solar.
Can You Earn Money Through Net Metering?
Most homeowners should think about:
Reducing Electricity Purchases
rather than “earning money.”
The primary benefit is maximizing the utilization of rooftop solar generation and reducing dependence on purchased electricity.
Biggest Net Metering Mistakes
Installing Wrong Capacity
Undersized systems reduce savings.
Oversized systems may not match consumption patterns.
Choosing Cheap Installers
Poor engineering often creates operational problems.
Ignoring Roof Design
Shading and orientation directly affect generation.
Not Understanding Utility Requirements
Professional guidance is important before installation.
