The shift towards sustainable energy has propelled India to be a global force in solar energy initiatives, offering exciting possibilities for homeowners in Tamil Nadu. With registered solar panel dealers across the state providing competitive prices in 2024, the reduced installation costs and government subsidies and support systems have made solar power a viable option. The state's increasing focus on clean energy alternatives with a lower carbon footprint has made solar energy a popular choice for many households.
This comprehensive guide covers everything you need to know about Tamil Nadu's solar power subsidies, helping you make an informed decision about your home's energy use.
The Tamil Nadu Government has inaugurated a Rooftop Solar Subsidy Scheme in partnership with the Government of India (Ministry of New and Renewable Energy—MNRE). This scheme has made solar power more accessible to Tamil Nadu consumers through the services of handpicked dealers. The solar power subsidy in Tamil Nadu is available for grid-connected systems. An on-grid solar system is more affordable since it does not require solar batteries. Consumers can also opt for a hybrid model system with solar batteries for on-site power reserves. However, this off-grid hybrid system is not eligible for subsidy.
Here's a detailed breakdown of solar power subsidy and system costs in Tamil Nadu:
| S. No. | Solar System Capacity in kilowatts (kW) | Tentative Price in Rs. (₹) | Subsidy in Rs. (₹) | Net Price Likely in Rs. (₹) |
|---|---|---|---|---|
| 1 | 1 | 75,000–85,000 | 30,000 | 45,000–55,000 |
| 2 | 1 | 1,50,000–1,70,000 | 60,000 | 90,000–1,10,000 |
| 3 | 1 | 1,90,000–2,16,000 | 78,000 | 1,10,000–1,37,000 |

Note: The scheme does not cover commercial or industrial consumers.
Getting a solar panel subsidy in Tamil Nadu is simple through the MNRE’s portal, the Rooftop Solar National Portal. The portal offers a user-friendly interface with simplified pricing and subsidy calculations across different slabs, making the application process straightforward. Under the PM Surya Ghar Muft Bijli Yojana scheme, over one crore households in Tamil Nadu already get monthly free electricity.
Step-by-step process: The National Portal for Rooftop Solar has outlined the process on its website. Here's how to get your solar installation with a subsidy:
Installing solar panels with government subsidies offers multiple benefits, from environmental impact to financial savings. Here's what you can expect:
Though residential rooftop solar adoption has been slow, improved subsidy policies by the state government are set to accelerate home solar installations in the coming years.

Switching to solar energy is a significant move for homeowners looking to cut down on their electricity costs while playing a part in protecting our environment. Figuring out the quantity of solar panels your house requires is not just an eco-conscious decision. It is a step towards financial liberation and self-sufficiency in energy.
This guide from Nantech, the leading solar panel supplier and dealer in Chennai, walks you through the essentials of calculating your energy consumption, realising potential savings on electricity expenses, and making informed choices regarding installing solar panels.
Let us delve into how the power of the sun can light up your way to a brighter, more sustainable future.
Understanding the electricity your house uses is the initial step in determining the required total sum of solar panels. This understanding assists you in deciding the size of the solar system that will best fulfil your energy demands.
Begin by examining your utility bills, which offer a wealth of data on your monthly electricity use. Analyse your consumption over the previous year to compute your daily and yearly average electricity usage, setting the stage for determining the required quantity of solar panels.
Note that electricity consumption varies widely among different homes. Key aspects influencing this include:
Taking these aspects into account aids in estimating your energy demands and the necessary solar system size more accurately.
Imagine your family uses around 900 kWh monthly. To find your day-to-day usage, divide this figure by the days in a month, resulting in an average daily consumption of about 30 kWh.
When picking solar panels for your residence, it is crucial to understand three aspects:
The wattage of a solar panel indicates the electricity it can generate under ideal conditions. Currently, residential solar panels on the market vary from 250 to 400 watts per piece. A 300-watt panel, for example, will produce more electricity than a 250-watt one under identical conditions. Hence, opting for higher-wattage panels might mean you will need fewer of them, especially if your roof space is limited.
Efficiency is another essential element, reflecting the percentage of sunlight a panel can convert into usable electricity. Recent advancements in solar technology have significantly boosted panel efficiency, making solar a more feasible option for homeowners. High-efficiency panels transform more sunlight into electricity, necessitating less space to meet your energy needs.
As solar technology progresses, the efficiency of solar panels continues to rise. This improvement is crucial for homeowners contemplating solar energy. With the latest advancements in photovoltaic (PV) technology, panels now capture and convert sunlight into electricity more efficiently, enhancing the effectiveness of solar systems even in less sunny locales.
The decision on the correct solar panel wattage hinges on various factors, including your home’s energy use and roof space availability.
To select the most fitting panel wattage:
To calculate the required solar panels for your residence, utilise this formula:
Wattage of solar panel wattage x maximum sunlight hours x total panel count = Daily power consumption
Assuming your house consumes 30 kWh daily, you are considering 300-watt panels, and your area gets an average of 5 maximum sunlight hours daily, you would need about 20 solar panels to meet your daily energy requirements.
While these estimates offer a general idea, several variables can impact the precise sum total of panels needed. These include your roof's orientation and slope, potential obstructions like trees or buildings, and the panels' efficiency over time.
Hence, seek guidance from solar experts who can conduct a thorough assessment to ensure your solar panel system is accurately sized.
With the correct quantity of solar panels, you can notably reduce your electricity expenses and contribute to a sustainable future. Remember, each home is unique, so a personalised assessment is essential to fully harness solar energy's benefits.
When contemplating solar panels for your residence, comprehend the initial outlay and the potential return on investment (ROI). The installation cost encompasses the following:
Government incentives and tax deductions significantly alleviate initial costs and enhance the financial feasibility of solar projects. These benefits can drastically reduce the upfront investment, rendering solar energy an even more appealing option. Investigating the incentives available in your locale is imperative to fully leverage these opportunities.
Regular maintenance is essential for maximising the lifespan of your solar panels and ensuring continued savings. By carefully weighing the initial expenses, potential savings, and available incentives, you can make a well-informed decision about solar energy and enjoy the financial and environmental benefits for years ahead.
To ensure your solar panels remain efficient and durable, several vital practices are essential:
Many options exist for those who prefer professional services to maintain their solar panel systems. Professional cleaning and maintenance services ensure your setup is inspected and cleaned by experts, which is especially advantageous for those unable to perform these tasks themselves or seeking to guarantee a thorough examination.
As our exploration of solar panels' potential to significantly trim down electricity costs and enhance energy self-sufficiency concludes, it is evident that the journey toward adopting solar energy is both fulfilling and essential.
With knowledge of calculating your house's solar needs and the impressive savings achievable, you are now ready to make a decisive move towards sustainability.
