Guide to On-Grid Solar Systems
An on-grid solar system, also referred to as a grid-connected system, is directly linked to the utility grid, allowing seamless integration with your local power supply. One of the key benefits of installing an on-grid solar system at home is the financial incentive provided by government subsidies. In India, homeowners can avail subsidies for rooftop on-grid solar installations, typically ranging from ₹30,000 to ₹78,000, depending on the system’s capacity.
Cost of On-Grid Solar Systems
The cost of an on-grid solar system varies based on factors such as location, system size, and additional components. To provide a sense of pricing, here are approximate costs for two different cities in India:
- 3 kW on-grid solar system in Telangana with subsidy: ~₹1,40,000
- 5 kW on-grid solar system in Telangana with subsidy: ~₹3,10,000
Note: These prices are indicative as of September 2025 and may vary depending on factors like city, local utility charges, panel type, inverter specifications, mounting structure design, after-sales service package, roof characteristics, and any savings guarantees offered. Prices are subject to change, so it’s advisable to consult with a solar provider for an accurate quote.
Understanding On-Grid Solar Systems
This guide explores the essentials of on-grid solar systems, including how they function, cost breakdowns (with and without subsidies), and practical tips for installation. Read on to learn how an on-grid solar system can power your home efficiently while reducing your electricity bills and contributing to a sustainable future.
Key Components of an On-Grid Solar Power System
An on-grid solar system, when properly maintained, can provide clean energy for up to 25 years. Regular maintenance is key to ensuring optimal performance, and professional cleaning services are recommended over using sprinklers, which can harm the panels. Below is a detailed overview of the essential components that work together to power your home with solar energy.
- Solar Panels: Solar panels are the most recognizable part of an on-grid solar system, typically installed on rooftops facing south to maximize sunlight exposure. These panels capture sunlight and convert it into direct current (DC) electricity.
- Interesting Fact: The electricity generated by solar panels is DC, but household appliances run on alternating current (AC). This is where the solar inverter comes into play, converting DC into usable AC power.
- Solar Inverter: The solar inverter is a critical component, transforming the DC electricity produced by solar panels into AC electricity suitable for home use. Without this conversion, the energy generated by the solar system would be incompatible with most household appliances, making the inverter indispensable.
- Mounting Structures: Mounting structures are sturdy frameworks that secure solar panels in place. These structures must be durable enough to support the panels’ weight and withstand harsh weather conditions, such as strong winds or storms, for the system’s 25-year lifespan. High-quality mounts are often made from galvanized steel to prevent rust and corrosion. For example, advanced mounting systems can resist wind speeds up to 170 km/h and feature protective coatings to ensure longevity.
- Solar Accessories: Though often overlooked, solar accessories are vital for the system’s functionality. These include:
- AC and DC Cables: These cables connect the solar panels, inverter, and other components, enabling the flow of electricity throughout the system.
- DC Combiner Box: This box consolidates and isolates DC current from the panels, which can reach high voltages (up to 1,000 volts or more). It safely directs the DC power to the inverter for conversion to AC.
- AC Combiner Box: After conversion, AC power from the inverter is routed through this box, which organizes the AC output from multiple inverters if applicable.
- Earthing Strips and Wires: These ensure the system is safely grounded to prevent electrical hazards. All DC connections use specialized MC4 connectors for secure and reliable wiring.
- Bi-Directional Meter: Also called a net meter, the bi-directional meter tracks the electricity exchanged with the grid. It monitors:
- Electricity supplied to the grid from the solar system.
- Electricity drawn from the grid when solar production is insufficient.
- This meter is essential for the system to function as an on-grid setup. At the end of each billing cycle, the meter’s readings determine:
- Units supplied to the grid, which can reduce your electricity bill.
- Units consumed from the grid, which are added to your bill.
How Net Metering Works: If your solar system generates more electricity than you use, the excess is sent to the grid, offsetting your bill. Conversely, if you draw additional power from the grid, those units are accounted for in your billing.
By integrating these components, an on-grid solar system efficiently powers your home while contributing to a sustainable future.
How Does an On-Grid Solar System Work?
Now that you know the components of an on-grid solar system, let’s look at how they function together to turn sunlight into usable electricity for your home.
- Capturing Sunlight and Generating DC Power: Solar panels, made up of photovoltaic (PV) cells, absorb sunlight and trigger the movement of electrons within their semiconductor layers. This activity produces direct current (DC) electricity. The output depends on panel quality, available sunlight, and shading conditions—more sunlight equals higher generation.
- Conversion of DC to AC through the Inverter: Since household appliances and the grid operate on alternating current (AC), the solar inverter converts the DC produced by panels into grid-compatible AC. Advanced inverters also come with MPPT (Maximum Power Point Tracking) technology, which continuously optimizes voltage and current to maximize energy harvest.
- Role of the Net (Bi-Directional) Meter: The converted AC power flows through a bi-directional or net meter. This smart meter tracks both:
- Electricity supplied by the grid to your home.
- Surplus solar electricity sent back from your system to the grid.
This ensures your bill reflects only the net consumption after accounting for imports and exports.
- Powering Your Home: During the day, your household devices—fans, lights, TVs, refrigerators, and air conditioners—use solar electricity first. This lowers your dependence on grid power, often reducing electricity bills drastically.
- Exporting Surplus Solar Energy: Whenever your panels generate more power than your home consumes, the extra electricity is automatically pushed back into the grid through the net meter. Depending on your state’s net metering policy, you either earn credits or monetary benefits for this exported energy.
- Drawing Power from the Grid: At night or on cloudy days, when solar generation is insufficient, the system seamlessly imports electricity from the grid. If you’ve earned credits earlier, they are adjusted against your consumption before billing, ensuring uninterrupted power supply.
Go Solar in Telangana and Andhra Pradesh: Your Guide to On-Grid Solar Systems in 2025
Switching to solar energy is a smart move for homeowners in Telangana and Andhra Pradesh. With the Indian government’s generous subsidies and the sunny climate of these states, installing an on-grid solar system can save you money while helping the environment. Let’s break down everything you need to know about costs, subsidies, and benefits, with a focus on Unilux Solar as your trusted partner.
Central Government Subsidies for On-Grid Solar Systems
Under the PM Surya Ghar Muft Bijli Yojana, the Indian government offers subsidies for on-grid rooftop solar systems, and these apply uniformly across all states, including Telangana and Andhra Pradesh:
- 1 kWp: Rs. 30,000
- 2 kWp: Rs. 60,000
- 3 kWp and above: Rs. 78,000 (maximum cap)
Note: The subsidy is capped at Rs. 78,000 for systems of 3 kWp or larger.
On-Grid Solar System Prices in Telangana and Andhra Pradesh (2025)
Below is a consolidated table of estimated prices for on-grid solar systems in Hyderabad (Telangana) and Vijayawada (Andhra Pradesh) for various system sizes, including subsidies, as of April 29, 2025. Prices are indicative for Unilux Solar’s base variant (6ft mounting structure) and may vary based on city, DISCOM charges, panel type, inverter type, and other factors.

What’s the Return on Investment (ROI)?
Your ROI depends on factors like the type of panels, inverter, and sunlight exposure. For example, a 3 kW system in Hyderabad, costing around Rs. 1,32,000 after subsidy, could save you significantly over 25 years. Assuming an electricity tariff of Rs. 12 per unit (with a 3–6% annual increase) and a 1% annual system degradation, you could save ~Rs. 16 lakhs over 25 years. The system typically pays for itself in 3–5 years, after which you enjoy virtually free electricity.
