Solar panel price list Tamil Nadu 2026
Rooftop solar prices in Tamil Nadu have stabilised in 2026 thanks to high local demand and PM Surya Ghar volume. Below is the all-in installed cost for a typical residential on-grid system using Tier-1 panels (e.g., Adani, Tata Power Solar, Rayzon, or Waaree) and a grid-tie inverter.
| System | Gross price | PM Surya Ghar subsidy | Net price |
|---|---|---|---|
| 1 kW on-grid | ₹65,000 – ₹75,000 | − ₹30,000 | ₹35,000 – ₹45,000 |
| 3 kW on-grid | ₹1,95,000 – ₹2,25,000 | − ₹78,000 | ₹1,17,000 – ₹1,47,000 |
| 5 kW on-grid | ₹3,25,000 – ₹3,75,000 | − ₹78,000 | ₹2,47,000 – ₹2,97,000 |
Prices are indicative for Tamil Nadu and include supply, installation, and commissioning. Final quote depends on roof type, cable run length, and inverter brand preference.

1 kW solar system: ideal for small homes & shops
Gross price
₹65k – ₹75k
Subsidy
− ₹30,000
Net price
₹35k – ₹45k
A 1 kW system generates roughly 4–4.5 units per day in Tamil Nadu — enough to offset a monthly EB bill of ₹500–₹700. Best for single-storey homes, small shops, or farm pump sheds.
3 kW solar system: the sweet spot for Tamil Nadu homes
Gross price
₹1.95L – ₹2.25L
Subsidy
− ₹78,000
Net price
₹1.17L – ₹1.47L
The 3 kW size is the most popular choice in Trichy, Madurai, and across Tamil Nadu because it captures the maximum PM Surya Ghar subsidy of ₹78,000. Expect 12–13.5 units per day — enough for a 2-3 BHK home with AC, fridge, and washing machine. Payback is typically 3.5–4.5 years.
5 kW solar system: large homes & small commercial
Gross price
₹3.25L – ₹3.75L
Subsidy
− ₹78,000
Net price
₹2.47L – ₹2.97L
A 5 kW system generates 20–22.5 units daily — ideal for large independent homes, guest houses, small offices, or clinics in Tamil Nadu. Although the subsidy is still capped at ₹78,000, the larger system brings faster absolute savings and future-proofs against rising TNEB tariffs.
Extra costs you should budget for
The table above covers standard on-grid installation. A few situations may add to the total:
- Hybrid inverter upgrade — if you want battery backup later, add ₹25,000–₹40,000 for a hybrid inverter (e.g., Deye, Growatt).
- Lithium battery — a 5 kWh lithium battery (51.2V / 100Ah) costs ₹75,000–₹95,000 and gives 4–6 hours of backup.
- Civil / RCC work — flat concrete roofs may need elevated structures or waterproof drilling; budget ₹5,000–₹15,000.
- Lightning arrestor & earthing — mandatory for TANGEDCO approval; usually bundled in our quote.
- AMC / cleaning service — optional annual maintenance at ₹3,000–₹5,000/year keeps panels at peak efficiency.

Frequently asked questions about solar panel prices in Tamil Nadu
Why do 1 kW and 3 kW systems have very different per-kW prices?
Smaller systems have higher per-kW labour and overhead costs (mounting, cabling, inverter). A 1 kW install is roughly ₹65,000/kW, while a 3 kW install drops to ~₹65,000–₹75,000/kW gross because fixed costs are spread across more capacity.
Is the PM Surya Ghar subsidy deducted upfront or refunded later?
It is a DBT (Direct Benefit Transfer) credited to your bank account after net-meter commissioning — typically within 30 days. You pay the net amount to the installer or arrange a solar loan for the full gross cost and receive the subsidy separately.
Do prices differ between Trichy, Madurai, and Chennai?
Marginally. Transport and labour rates are similar across Tamil Nadu, but Chennai may be 5–10% higher due to permit complexity. Trichy and Madurai are very competitive, and SVN Safetech offers the same transparent pricing statewide.
Can I get a loan for the full gross amount?
Yes. SBI, Canara Bank, and a few NBFCs offer collateral-free rooftop solar loans up to ₹2 lakh at ~7% p.a. You can apply for the loan amount equal to the gross cost and still receive the subsidy into your account later.
