An on-grid solar system, also known as a grid-tied or grid-connected solar system, is connected to the public electricity grid. This type of system allows you to generate your own electricity, use it in real-time, and feed any excess back into the grid. With net metering, you receive credits for the surplus energy you export, reducing your overall electricity bill.

Understanding ROI for Solar Systems
Return on Investment (ROI) is a key metric used to evaluate the profitability of an investment. In the context of solar systems, ROI measures the financial benefits gained from the solar installation relative to its cost. Essentially, it helps you determine how long it will take to recoup your investment and start saving money.
How ROI is Calculated:
ROI is calculated using the formula:
ROI =(Net Profit / Total Investment) × 100
Net Profit: The total savings or earnings from the solar system over its lifetime minus the initial investment cost.
Total Investment: The upfront cost of purchasing and installing the solar system.
Example of ROI Calculation
Let’s consider a practical example to illustrate ROI for a 5 kW on-grid solar system:
Initial Investment:
Cost of solar system: ₹3,00,000
Installation cost: ₹20,000
Total Investment: ₹3,20,000
Annual Savings:
Average annual electricity savings: ₹30,000
System Lifetime:
Expected life of the system: 25 years
Total Savings Over System Lifetime:
Total savings: ₹30,000/year × 25 years = ₹7,50,000
Net Profit:
Net Profit = Total Savings - Total Investment
Net Profit = ₹7,50,000 - ₹3,20,000 = ₹4,30,000
ROI Calculation:
ROI = (₹4,30,000 / ₹3,20,000) × 100 = 134.38%
Conclusion:
In this example, the ROI of 134.38% indicates that over the lifetime of the solar system, you will earn back more than double your initial investment. The system will pay for itself in about 10.7 years, after which you will start enjoying pure savings.
By understanding and calculating ROI, you can make an informed decision about investing in solar energy, ensuring that it is a financially viable and beneficial option for your needs.
Key Components
Solar Panels
Capture sunlight and convert it into direct current (DC) electricity.
Inverter
Converts DC electricity from the panels into alternating current (AC) electricity, which is compatible with your home or business.
Grid Connection
Allows excess electricity to be fed into the public grid and draws power from the grid when solar production is insufficient.
Net Meter
Tracks the electricity you consume and the surplus you export, enabling you to benefit from net metering.
System Design & Customization
On-grid solar systems are connected to the local electricity grid, allowing for energy efficiency and potential savings through net metering
Energy Consumption: Designed to offset a portion or the entirety of the electricity bill, depending on the daily energy usage.
Net Metering: The system is equipped to send excess energy back to the grid, allowing homeowners or businesses to earn credits on their electricity bill.
Solar Array Size: Determined by the daily energy consumption and available rooftop space for panel installation.
Inverter Capacity: Converts DC power from solar panels to AC power, matching the grid’s voltage and frequency to ensure seamless power supply.
Grid Backup: The system seamlessly switches to grid power when solar energy is insufficient, ensuring continuous power supply without the need for battery storage.
How On-Grid Solar Systems Work
An On-Grid Solar System, also known as a grid-tied or grid-connected system, is designed to work seamlessly with the local electricity grid. Here’s how it functions:
1. Solar Panels Capture Sunlight:
The solar panels installed on your rooftop or other suitable locations capture sunlight and convert it into direct current (DC) electricity.
2. Inverter Converts DC to AC:
The DC electricity produced by the solar panels is sent to an inverter, which converts it into alternating current (AC) electricity. AC is the standard form of electricity used by household appliances and the power grid.
3. Power Your Home or Business:
The converted AC electricity is then used to power your home, office, or industrial facility. During daylight hours, solar energy can cover a significant portion, if not all, of your energy needs.
4. Excess Energy is Sent to the Grid:
Any excess electricity generated by your solar system that isn’t immediately used is fed back into the local power grid. This surplus energy can earn you credits through a process known as net metering.
5. Draw Power from the Grid When Needed:
At night or during cloudy days when your solar system isn’t producing enough energy, your system automatically draws electricity from the grid to meet your power needs. The net metering credits accumulated during high production periods can offset the cost of this electricity.
6. Net Metering:
A special meter tracks both the energy you consume from the grid and the excess energy your solar panels send back. This way, you’re billed only for the “net” energy you use (total consumption minus the energy you generated).
What is Net metering
It is a billing mechanism that allows homeowners or businesses with solar energy systems to receive credits for the excess electricity they generate and feed back into the local power grid. Here’s how it works:
1. Solar Energy Generation:
When your solar panels produce more electricity than you need during the day, the excess energy is sent to the local utility grid.
2. Earning Credits:
Your utility company tracks the amount of excess energy you send to the grid. For this, they give you credits, which are applied to your electricity bill.
3. Using Credits:
At night or during cloudy days when your solar panels aren’t producing enough electricity, you draw power from the grid. The credits you’ve earned offset the cost of this electricity, reducing or even eliminating your electricity bill.
4. Billing
At the end of the billing period, you’re only charged for the "net" energy you consumed—total energy used minus the energy you sent to the grid. If you generate more than you consume, the extra credits can often be carried over to the next billing cycle.
Benefits of Net Metering:
Cost Savings: Reduces electricity bills by allowing you to offset energy costs.
Encourages Renewable Energy: Makes solar energy more financially attractive by providing a way to recoup investment costs faster.
Grid Stability: Helps stabilize the grid by providing additional energy during peak production times.
Applications
