Synopsis of On-grid solar power systems

A grid-tied or on-grid solar system is one that is linked to the grid. For their electrical demands, the majority of Indian homes with a dependable grid connection rely on on-grid solar power. And at Resonant Technologies, we're experts at setting up rooftop solar power systems that are connected to the grid for both private residences and apartment buildings.

The home's off-grid solar power plant is a meticulous assembly of many parts:
solar-panel
solar-powered inverter
mounting frameworks
Two-way meter
solar-related accessories

In terms of classification, an off-grid solar power system built for a single family or other smaller application comes in various capacities, ranging from 2 kW to 10 KW. Generally speaking, a solar system's capacity can be significantly more than 10 kW.

Here's what happens when you install an on-grid solar system:

Solar panels absorb sunlight and convert it into direct current (DC)
⇩
The DC current goes into the inverter that converts it into alternating current (AC)
⇩
The alternating current is fed into a bidirectional meter
⇩
The bi-directional meter supplies AC power to your home to run all household appliances
⇩
This meter supplies excess electricity (units that are not consumed) to the grid
⇩
When the exported units are needed later (eg. at night), the bi-directional meter imports them from the grid
The exchange of electricity back and forth from the grid via the bi-directional meter is called net metering.

On-grid Solar system types based on their capacities

In terms of subsidy, the government offers a subsidy for an on-grid solar system that does not exceed the capacity of 10 kW.
Let’s find out the basics since the calculations will also help you in finding out the size of the solar system that you should install at your home.
1 kW on-grid solar system
A 1 kW grid-tied solar system produces roughly 1400 units of electricity on an average/year, which means:
The approximate units generated by a 1 kW on-grid solar system in a month will be 116 units (1400/12)
If the average electricity tariff/unit in your city is ₹8, you will save approximately ₹11,200 in one year (1400 X 8)
2 kW on-grid solar system
A 2 kW grid-tied solar system will produce roughly twice the units produced by a 1 kW system i.e., 2800 units on an average/year.

It means:
The approximate units generated by a 2 kW on-grid solar system in a month will be 232 units (116 x 2)
If the average electricity tariff/unit in your city is ₹8, you will save approximately ₹22,400 in one year (2800 X 8) 3 kW on-grid solar system
A 3 kW grid-tied solar system will roughly produce three times the units produced by a 1 kW system i.e. 4200 units on an average/year.

It means:
The approximate units generated by a 3 kW on-grid solar system in a month will be 348 units (116 x 3)
If the average electricity tariff/unit in your city is ₹8, you will save approximately ₹33,600 in one year (4200 x 8) 5 kW on-grid solar system
A 5 kW grid-tied solar system will produce roughly 5 times the units produced by a 1 kW on-grid solar system i.e., 7000 units on an average/year.

It means:
The approximate units generated by a 5 kW on-grid solar system in a month will be 580 units (116 x 5)
If the average electricity tariff/unit in your city is ₹8, you will save approximately ₹56,000 in one year (7000 x 8) 10 kW on-grid solar system
A 10 kW grid-tied solar system will produce roughly 10 times the units produced by a 1 kW on-grid solar system i.e., 14,000 units on an average/year.

It means:
The approximate units generated by a 10 kW on-grid solar system in a month will be 1160 units (116 x 10) If the average electricity tariff/unit in your city is ₹8, you will save approximately ₹112,000 in one year (14,000 x 8)
