जानिए भारत में 3kW solar system की सरकारी सब्सिडी के बाद वास्तविक लागत कितनी होती है। Central subsidy, price after subsidy, city/state differences, units generation, savings और आवेदन प्रक्रिया। Updated 2025.
🟩 1. Introduction – 3kW Solar System Subsidy का Importance
2025 के Renewable Energy push में, भारत सरकार खासकर PM Surya Ghar Muft Bijli Yojana जैसी rooftop solar subsidy schemes के ज़रिये residential users को clean energy अपनाने के लिये subsidy देती है।
विशेष रूप से 3kW solar system छोटे से मध्यम परिवारों के लिए एक सबसे popular solar capacity है क्योंकि यह घर के अधिकांश बिजली इस्तेमाल को offset कर सकता है।
इस ब्लॉग में हम बताएँगे कि 3kW solar system की वास्तविक लागत (subsidy के बाद) कितनी होती है, किस तरह से subsidy मिलती है, savings कितनी हो सकती है, और इसे कैसे apply करना है।
🟩 2. Govt Subsidy Structure for 3kW Solar (2025)
2025 में भारत में PM Surya Ghar Muft Bijli Yojana के तहत, rooftop solar systems पर central government subsidy दी जाती है। यह subsidy system capacity पर आधारित होती है और अधिकांश residential on-grid systems में मिलती है:
📊 Central Government Subsidy
| System Size | Subsidy Amount | Notes |
|---|---|---|
| 1 kW | ₹30,000 per kW | Residential |
| 2 kW | ₹30,000 × 2 = ₹60,000 | Residential |
| 3 kW | ₹78,000 (fixed maximum) | Maximum subsidy cap |
| Above 3 kW | ₹78,000 (cap remains) | Extra capacity no central subsidy |
Meaning:
3kW systems receive a fixed ₹78,000 subsidy under the scheme — that’s the maximum central subsidy limit.
⚠ Important: Subsidy applies only to on-grid rooftop solar systems installed through MNRE/DISCOM empaneled vendors. Off-grid systems generally aren’t eligible for central rooftop subsidy (unless specific state incentives apply).
🟩 3. 3kW Solar System Price Before Subsidy (2025)
Market rates vary by city, quality of components, inverter type, mounting structure, etc., but 2025 average costs for a 3kW on-grid solar system are generally:
| Cost Component | Typical Price (₹) |
|---|---|
| Solar Panels (3 kW) | ₹75,000 – ₹84,000 |
| Inverter + Accessories | ₹22,000 – ₹35,000 |
| Mounting, Wiring, Earthing | ₹20,000 – ₹30,000 |
| Installation & Labour | ₹10,000 – ₹15,000 |
| Net Meter & Documentation | ₹3,000 – ₹5,000 |
| Total Before Subsidy | ₹1,65,000 – ₹2,15,000 |
💡 System cost usually includes panels, inverter, mounting structure, wiring, protection devices and installation fees.
🟩 4. 3kW Solar Subsidy Price After Govt Support
जब आप central subsidy ₹78,000 apply करते हैं, तो effective cost हो जाता है:
🧾 Indicative Price After Central Subsidy
| Before Subsidy | Central Subsidy | After Subsidy (₹) |
|---|---|---|
| ₹1,65,000 | ₹78,000 | ₹87,000 |
| ₹1,80,000 | ₹78,000 | ₹1,02,000 |
| ₹2,15,000 | ₹78,000 | ₹1,37,000 |
📌 Typical 3kW after-subsidy price: ₹87,000 – ₹1,37,000 approx. — depending on city and installation conditions.
👉 Many quotes observed across regions show similar numbers — after subsidy, 3kW systems often fall in the ₹80,000 – ₹1,40,000 range.
🟩 5. City-wise Example – 3kW Subsidy Price (Indicative)
| City | Before Subsidy | Subsidy | After Subsidy |
|---|---|---|---|
| Pune | ₹1,89,000 | ₹78,000 | ₹1,11,000 |
| Bhopal | ₹2,05,000 | ₹78,000 | ₹1,27,000 |

(Indicative range based on market price data and local installation differences.)
🟩 6. 3kW System Se Kitni Electricity Milegi & Savings?
A 3kW solar system typically generates:
✔ ~350–450 units per month — depending on sun hours & orientation
✔ ~4,200–5,400 units per year
📊 Savings Estimate
Assuming electricity tariff ₹7–₹9 per unit:
- Monthly savings ≈ ₹2,450 – ₹3,600
- Yearly savings ≈ ₹29,000 – ₹43,000
This means a 3kW solar system can significantly reduce your electricity bills over time and deliver a quick return on investment, especially after subsidy.
🟩 7. Why 3kW is a Popular Capacity?
3kW solar systems are ideal for:
✔ 2–3 BHK homes with monthly usage ~300–450 units
✔ Medium families with refrigerator, TV, fans, lights
✔ Net-metering benefit with grid balance
✔ Quick payback with subsidy support
Average rooftop space required is around ~180–220 sq. ft.
🟩 8. Eligibility & How to Apply for Subsidy (3kW)
To get the central subsidy, you must follow a process:
✔ Eligibility
- Residential rooftop system
- On-grid setup (net metering)
- Installation through MNRE/DISCOM empaneled vendor
- System designed as per grid code
- Application on official portal
🧾 Steps to Apply
- Visit the National Rooftop Solar Portal
- Register with your details & choose vendor
- Site inspection & feasibility approval
- Installation & commissioning
- DISCOM inspection
- Subsidy credited directly to your account
Typically, subsidy is credited within a few weeks after successful installation and board approval.
🟩 9. Additional State Subsidies (Optional)
In addition to central subsidy, some states provide extra incentives:
- Some districts may offer top-up subsidies
- Local DISCOM rebates & bonus programs
- Special incentives for low-income families or BPL groups
For example, Haryana has programs where additional assistance up to tens of thousands can be provided depending on income category.
👉 Always check with your state DISCOM or installer for any additional state/subsidy schemes available locally.
🟩 10. Payback Period After Subsidy
Because the subsidy reduces upfront cost significantly and monthly electricity savings are high, payback periods for 3kW systems are typically:
🕛 Payback Time: ~3–4 years
After this, you enjoy nearly free electricity for 20+ years given solar panel lifespan (20+ years) and minimal maintenance costs.
🟩 11. Key Things to Remember
✔ 3kW system subsidy capped at ₹78,000 and applied directly
✔ Off-grid/hybrid systems may not get full rooftop subsidy
✔ Actual final cost varies by installer, brand, location
✔ Net-metering boosts savings & economics
✔ Always verify price with 2–3 installers
🟩 12. Conclusion – 3kW Solar Subsidy Price After Govt Support
2025 में 3kW on-grid solar rooftop system के लिए typical installed cost بدون subsidy ₹1,65,000 – ₹2,15,000 है।
Central subsidy ₹78,000 मिलने के बाद effective price आमतौर पर:
📌 ₹87,000 – ₹1,37,000 approx.
(after govt support and dependent on installation factors) — making it one of the most economical residential solar configurations that deliver high electricity production and quick ROI
