Choosing the Best Solar Pafor Your Home
With rising electricity costs and increasing environmental awareness, many homeowners in Tamil Nadu are turning to solar power. With ample sunlight and rising electricity costs, installing a solar system can help you save money and lower your carbon footprint. But choosing the right solar system for your home can be overwhelming. From panel types to government subsidies, this guide covers everything you need to make a smart, cost-effective decision.
1. Understand Your Power Needs
Start by reviewing your monthly electricity usage in units. Most families in Tamil Nadu typically consume between three to six kilowatts of power per month.
Tip: Check the average units used in your past six electricity bills to decide the right solar system size.
2. Types of Solar Systems
There are three main types of solar systems to choose from
On-Grid System
Works with the electricity board connection. Excess power is sent back to the grid. No battery required.
Best for: Homes with steady power supply
Off-Grid System
Works independently with battery storage. It continues to power your home even during outages.
Best for: Homes in rural or power-cut-prone areas
Hybrid System
Combines grid connection with battery backup. Offers flexibility and power backup.
Best for: Homes that want energy savings and power backup
Tip: On-grid systems are more affordable, while hybrid systems give you both savings and power security.
3. Calculate Rooftop Space
Tamil Nadu has strong sunlight throughout the year, but you still need proper space.
1 kW system needs approx. 80–100 sq. ft. of shade-free roof.
Tip: South-facing rooftops get the best sunlight and generate more energy.
VEL Systems offers free rooftop assessments in Chengalpattu and Madhuranthagam.
4. Know the Cost and ROI
Here’s a rough estimate (2025):
| System Size | Approx. Cost (₹) | Avg. Monthly Savings |
| 1 kW | ₹70,000 – ₹90,000 | ₹900 – ₹1,200 |
| 3 kW | ₹2.2L – ₹2.8L | ₹2,500 – ₹3,000 |
| 5 kW | ₹3.5L – ₹4.5L | ₹4,000 – ₹5,000 |
Costs may vary based on brands and installation type.
Tip: The larger the system, the faster your return on investment through bill savings.
5. Check for Government Subsidies
Tamil Nadu residents can avail 30–40% subsidy under MNRE and TANGEDCO schemes (for residential rooftop systems).
Required:
- Permanent EB connection
- Roof ownership
Tip: Apply for subsidy only through authorized vendors like VEL Systems to avoid rejections.
6. Choose the Right Solar Installer
Look for solar providers who
- Are registered with MNRE
- Offer end-to-end services including design, installation, and support
- Have local presence and service experience
VEL Systems delivers complete solar solutions in Chengalpattu, Madhuranthagam, and surrounding regions.
Tip: Read local customer reviews before finalizing your installer for better peace of mind.
7. Maintain Your Solar System
Solar panels are low-maintenance. Clean them every fifteen to thirty days to remove dust and dirt. Check inverter output regularly.
Tip: Schedule a professional check-up once a year to keep your system efficient and long-lasting.
Conclusion
Installing a solar system in Tamil Nadu is a cost-effective and eco-friendly decision. Choose the right system based on your electricity usage, location, and budget. With expert guidance and proper installation, you can enjoy long-term savings and energy independence.
