Sunlight is converted to DC electricity power by Solar PV module. This DC power is converted into AC power in synchronization with grid using grid tied solar inverters, the generated energy by solar system is recorded by solar meter and supplied as per loads need of building.
If power required by load is more than power generated than power is drawn from grid. This energy drawn is recorded as import energy units in ‘Net-meter’. If power required by load is less than power generated by solar system, then balance power is supplied to the grid. This energy supplied to grid is recorded as export units.
As per net metering policy, consumer has to pay for net units i.e. import-export of units.
The purpose of installing on-grid solar system is to reduce electricity bill.
Below is the table to understand how to choose on-grid solar system capacity based upon power consumption and monthly electricity meter reading.
Average daily power Estimated monthly bill Recommended on grid
consumption (units) @ Rs. 10 per unit solar PV system (kw)
0-5 units Rs.0 to 1500 1KW
5-10 unit Rs.1500 to 3000 2kw
10-15 units Rs.3000 to 4,500 3kw
15-25 units Rs. 4,500 to 7,500 5kw
25-50 units Rs. 7,500 to 15,000 10kw
50- 125 units Rs. 15,000 to 35,000 25kw
On-grid solar system price varies with the selection of brands, quality of products used, and system replacement warranty. Latest price list of the on-grid solar system in India.
On-Grid system Capacity Price (all inclusive)
1KW ₹ 60,000
2kw ₹ 1,20,000
3kw ₹ 1,80,000
5kw ₹ 3,00,000
10kw ₹ 6,00,000
25kw ₹ 15,00,000
The economics of rooftop solar energy in India has become extremely compelling. It makes great sense for Residential customers to use rooftop solar energy as it has become much cheaper than the grid electricity. You can convert your own property into a revenue-generating avenue by investing in solar and achieving ROI in just 4-5 years.

The advantage of on-grid solar system is awesome, if you are not using electricity at your home, the power generated from solar system will be fed back to the grid. The state government will compensate your EB bill for sending electricity to gird in case of NET METER to Residential only
Yes, But it will be more effective , if we done survey of your consumption load, than matching the survey data to solar real time data.
