3 kW on grid system receives approximately ₹78,000 subsidy

4 kW on grid system receives the same ₹78,000 cap

Residential homes can apply easily through TANGEDCO with Heliostrom’s assistance

By claiming these subsidies, your solar panel price in Chennai drops by 30 to 40 percent.

4. Buy High Efficiency Panels for Maximum Value

High efficiency mono PERC panels or bifacial panels are ideal for Chennai’s sunny weather. They produce more energy from the same rooftop space.

Heliostrom provides Grade A panels that meet BIS and IEC certifications. This ensures that every rupee you spend gives you maximum energy output and a faster payback period.

5. Check Local Dealers but Verify Eligibility

Some homeowners in Chennai consider buying panels from local shops or suppliers like gdthangamaligai.in to save initial costs.

While this can reduce panel cost, subsidy eligibility applies only when installation is handled by an MNRE registered company like Heliostrom. This is important to consider before making a decision.

6. Evaluate Long Term Savings and ROI

The right solar panel system is not just about the initial price. A 3 kW system in Chennai can generate 360 to 400 units per month. This means a saving of approximately ₹30,000 annually.

With subsidy applied, you can recover your investment in 5 to 6 years. For larger systems, businesses often see ROI in 4 to 5 years.

7. Site Survey and Roof Assessment are Key

Your rooftop direction, shade, and tilt angle will influence performance. Heliostrom offers a free site survey to measure your roof capacity, design a proper structure, and ensure maximum daily generation.

8. Monitor Your System Performance

Installing solar is only the first step. Heliostrom provides remote monitoring systems so you can track unit generation, compare monthly savings, and detect faults early.

9. Choose Service and Warranty Over Low Price

A cheaper, unregistered installer may reduce upfront cost but can lead to higher long term losses. Heliostrom offers

25 years panel performance warranty

5 years inverter and installation warranty

Lifetime technical support for subsidy customers

10. Seasonal Timing and Price Advantage

Panel prices in India sometimes drop after major tenders or import duty cuts. Planning your purchase around seasonal offers can save an extra 5 to 10 percent. HelioStrom keeps customers informed so they buy at the right time.
