What Are Solar Panels and Why Do Costs Matter?
Solar panels are devices that capture sunlight and convert it into electricity using the photovoltaic (PV) effect. They’re the heart of any solar power system—used to power homes, businesses, and even farms.
When you think of solar panels and cost, you’re really thinking of multiple components: the panel itself, the inverter, mounting hardware, installation labor, and potential government subsidies. Understanding how each contributes to your total expense helps avoid surprises and boosts your return on investment (ROI).
Key Factors That Influence Solar Panel Costs
The price tag isn’t just about the panels—it’s the whole system. Here’s what makes up the cost of solar panel installation in India.
1. Panel Type: Monocrystalline vs. Polycrystalline vs. Bifacial
- Monocrystalline Panels: High efficiency (18–22%) and premium cost. Sleek black look.
- Polycrystalline Panels: Lower cost, moderate efficiency (~15–17%), blue tone.
- Bifacial Panels: Capture sunlight from both sides, great for ground-mounted systems.
👉 Pro tip: High-efficiency panels may cost more upfront but save more over 25 years.
2. System Size (kW)
The most common home systems range from 1 kW to 10 kW. Bigger systems generate more power but cost more. Here’s an average rate:
| System Size | Price Range (Before Subsidy) |
|---|---|
| 1 kW | ₹75,000 – ₹85,000 |
| 3 kW | ₹180,000 – ₹215,000 |
| 5 kW | ₹250,000 – ₹325,000 |
| 10 kW | ₹500,000 – ₹600,000 |
3. Rooftop Type & Mounting Structure
The installation complexity can add ₹10,000–₹50,000 more depending on whether your roof is:
- Flat (requires mounting tilt)
- Sloped (easier to align)
- Metal sheet (needs special clamps)
4. Type of Solar System
- On-grid: Connected to the electricity grid; no batteries.
- Off-grid: Includes batteries; ideal for remote areas.
- Hybrid: Grid + battery backup; most expensive.
5. Solar Inverter Cost
Essential for converting DC power to usable AC power. Inverter costs can range from:
₹20,000 to ₹80,000+, based on size and type (string or micro-inverters).
6. Location-Based Costs
Labor and material availability vary across Indian states. Cities like Chandigarh, Delhi, and Bangalore may have slightly higher service charges.
7. Other Components
- Wiring & Junction Boxes: ₹5,000–₹10,000
- Monitoring System: Optional, adds ₹5,000–₹20,000
- Net Metering Fee: Varies by DISCOM, ₹2,000–₹5,000
Cost Breakdown: Solar Panels and Installation
Here’s a full table for average solar system installation cost in India (before subsidy):
| Component | Approximate Cost (per kW) |
|---|---|
| Solar Panels | ₹30,000–₹40,000 |
| Inverter | ₹10,000 – ₹15,000 |
| Mounting System | ₹5,000 – ₹10,000 |
| Labor & Installation | ₹10,000 – ₹20,000 |
| Wiring & Accessories | ₹5,000 – ₹10,000 |
| Total | ₹60,000 – ₹85,000 |
Subsidy Schemes You Should Know in 2025
Central Government Subsidy (PM Surya Ghar Yojana)
- Up to 3 kW: 60% subsidy
- 4–10 kW: 40% subsidy
Subject to benchmark cost. Available only through DISCOM-empanelled vendors.
Example: If your 3 kW system costs ₹180,000, the subsidy could cover ₹108,000, reducing your cost to ₹72,000!
Solar ROI: Long-Term Savings
Let’s say your system produces 5 units/day and electricity costs ₹8/unit.
- Monthly savings: ₹1,200
- Annual savings: ₹14,400
- Payback period: 4–5 years
- Savings in 25 years: ₹3.5–₹4.5 lakhs!
Tips to Minimize Solar Panel Costs
- Always compare at least 3 quotes from local vendors.
- Ask about warranty, maintenance, and after-sales service.
- Consider solar loans or EMI schemes.
- Choose BIS-certified products and vendors listed under ALMM.

❓ FAQs About Solar Panels and Cost
Q1: Are solar panels worth the investment in India?
Yes! With a payback of 4–5 years and a 25+ year lifespan, solar panels significantly reduce electricity costs.
Q2: How much does a 1kW solar system cost with subsidy?
After subsidy, a 1kW on-grid system can cost as low as ₹30,000–₹35,000.
Q3: Do I need batteries with solar panels?
Only if you want an off-grid system. For most homes, on-grid systems are cheaper and more efficient.
Q4: Can I get a loan for solar panel installation?
Yes, many banks and solar vendors offer EMIs or financing schemes for residential users.
Q5: Which type of solar panel is most efficient?
Monocrystalline and Bifacial panels offer the highest efficiency, especially with TOPCon technology.
Q6: How long do solar panels last?
Most come with a 25-year warranty and can work efficiently for up to 30 years.
Q7: Can I install solar panels myself?
While it is technically possible to install solar panels yourself, professional installation ensures safety, eligibility for subsidies, and optimal performance.
Q8: What is the cost per watt of solar panels?
The cost per watt of solar panels typically ranges between ₹30 and ₹50, depending on the technology and brand.
Q9: What is net metering?
It allows you to sell excess solar power back to the grid, reducing your electricity bill.
Q10: Which is better—on-grid or off-grid solar systems?
On-grid is best for city homes with stable power. Off-grid is ideal for rural or unreliable grid areas.
Final Thoughts
Solar panels are no longer a luxury—they’re a smart, sustainable investment. As prices fall and government subsidies rise, 2025 is the perfect time to go solar. Whether you’re powering a home, farm, or office, understanding the real solar panels and cost helps you make a confident, cost-effective choice.
