If you're considering going solar in India, the first question on your mind is almost certainly: "How much is this going to cost me?" The answer isn't a simple number â it depends on your system size, the panels you choose, your state's policies, and what subsidies you're eligible for.
In this guide, we break down solar panel costs in India for 2025 comprehensively â so you can walk into a quote discussion informed and confident.
1. Average Solar Panel Costs in India (2025)
Solar panel prices in India have dropped significantly over the past decade. In 2025, the average cost of a complete grid-tied rooftop solar system (including panels, inverter, mounting structure, cables, and installation) ranges from:
âš40,000 â âš80,000 per kW before any government subsidies, depending on panel brand, inverter quality, and state.
This means a typical 3 kW system for a mid-sized home would cost âš1,20,000 â âš2,40,000 before subsidies, and after the central government subsidy of up to âš78,000, your effective cost drops to âš42,000 â âš1,62,000.
2. Cost by System Capacity
The table below shows approximate all-inclusive costs (panels + inverter + installation + net metering application) for different system sizes in India in 2025:
| System Size | Avg. Monthly Units | Cost Before Subsidy | Subsidy (Central) | Net Cost After Subsidy |
|---|---|---|---|---|
| 1 kW | 90â110 units | âš60,000ââš80,000 | âš30,000 | âš30,000ââš50,000 |
| 2 kW | 180â220 units | âš1,00,000ââš1,50,000 | âš60,000 | âš40,000ââš90,000 |
| 3 kW | 270â330 units | âš1,30,000ââš2,00,000 | âš78,000 | âš52,000ââš1,22,000 |
| 5 kW | 450â550 units | âš2,00,000ââš3,20,000 | âš78,000* | âš1,22,000ââš2,42,000 |
| 10 kW | 900â1100 units | âš4,00,000ââš6,00,000 | âš78,000* | âš3,22,000ââš5,22,000 |
* Central subsidy is capped at âš78,000 (for 3 kW). Systems above 3 kW may qualify for additional state-level subsidies. Prices vary by state and vendor.
3. Cost by Panel Brand
Panel quality and brand reputation significantly impact both cost and long-term performance. Here's a rough price guide by brand tier for 2025:
| Brand | Tier | Price Range (per Wp) | Efficiency |
|---|---|---|---|
| Tata Power Solar | Premium | âš28ââš35 | 20â22% |
| Adani Solar | Premium | âš26ââš33 | 20â22% |
| Waaree Energies | Mid-Premium | âš24ââš30 | 19â21% |
| Vikram Solar | Mid-Premium | âš24ââš30 | 19â21% |
| Luminous | Mid-Range | âš22ââš27 | 18â20% |
| Goldi Solar | Mid-Range | âš21ââš26 | 17â20% |
| Generic/Economy | Budget | âš16ââš22 | 15â18% |
For most homeowners, mid-premium brands like Waaree or Vikram offer the best balance of efficiency, warranty, and price. Premium brands like Tata and Adani offer better long-term assurance but at a higher upfront cost.

4. Factors That Affect Solar System Cost
Panel Type
Monocrystalline panels (the most common in 2025) are more efficient and slightly more expensive than polycrystalline panels. Bifacial panels, which generate energy from both sides, cost 10â15% more but can produce 5â10% more energy.
Inverter Type
String inverters (most common) are the most affordable option. Microinverters offer per-panel optimisation and longer warranties but cost 20â30% more. For most residential installations, a quality string inverter from Sungrow, ABB, or Growatt is the right choice.
Mounting Structure
A galvanised steel or aluminium mounting structure is critical for longevity. Budget systems may skimp on structure quality â always ask for the material specification. Expect to pay âš5,000ââš15,000 for a quality structure per kW.
State and Location
Labour costs, local DISCOM net metering charges, and state subsidies vary significantly. States like Rajasthan, Gujarat, and Maharashtra tend to have competitive pricing due to high installer density. Remote or hilly areas may cost 15â25% more due to logistics.
5. Government Subsidy: How Much You Can Save
Under the PM Surya Ghar Muft Bijli Yojana (launched February 2024), residential consumers can claim a central financial assistance subsidy of:
- 1â2 kW systems: âš30,000 per kW â Up to âš60,000 for a 2 kW system
- 2â3 kW systems: âš18,000 per kW for the additional capacity â âš18,000 extra for the 3rd kW
- Maximum subsidy: âš78,000 for a 3 kW or larger system
Additionally, several states offer their own subsidies on top of the central scheme. For example, Gujarat offers up to âš10,000 per kW, and Maharashtra has additional incentives for BPL families.
To claim the subsidy, you must register on the PM Surya Ghar portal and use an MNRE-empanelled vendor. For the complete step-by-step application process, read our Solar Subsidy Guide.
6. Return on Investment & Payback Period
Let's calculate the return on investment for a typical 3 kW system in a city like Jaipur (high solar irradiation, âš7/unit tariff):
| Parameter | Value |
|---|---|
| System Size | 3 kW |
| Total Cost (after âš78,000 subsidy) | ~âš72,000ââš1,00,000 |
| Annual Energy Production | ~4,200 kWh |
| Annual Bill Savings (@âš7/unit) | ~âš29,400 |
| Simple Payback Period | 2.5â3.5 years |
| System Lifespan | 25+ years |
| Lifetime Savings | âš6â7 lakhs |
Even in cities with lower tariffs, the payback period rarely exceeds 6â7 years. With tariffs increasing 3â5% annually, the financial case for solar only gets stronger over time.
Frequently Asked Questions
Economy-grade polycrystalline panels from domestic manufacturers are priced at âš16ââš22 per watt. However, we recommend mid-range or premium panels for better long-term performance and warranty assurance. A budget panel that degrades faster or fails early will end up costing you more.
A complete 1 kW rooftop solar system (on-grid) in India costs approximately âš60,000ââš80,000 before subsidies. After the PM Surya Ghar subsidy of âš30,000, your net cost is âš30,000ââš50,000. A 1 kW system generates approximately 90â110 units per month.
It depends on the vendor. Always ask for an all-inclusive quote that covers panels, inverter, mounting structure, wiring, DC MCBs, earthing, installation labour, and DISCOM net metering application charges. Some vendors quote only equipment costs, which can cause unpleasant surprises.
Yes. Several nationalised banks (SBI, Bank of Baroda) and NBFCs offer solar loans at 7â10% interest rates, often with no collateral for amounts under âš5 lakhs. The PM Surya Ghar scheme also enables loan disbursement linked to subsidy claims. Some states offer interest subsidy on solar loans for BPL families.
