Intro

Nalanda mein har mahine ₹3000 se ₹4000 ka electricity bill ek aam baat hai, especially jab ghar mein 2 AC aur fridge jaisa load ho.

Ab question yeh aata hai – kitna kW solar system chahiye, jo yeh load handle kar sake? Kya 3kW kaafi hai ya 5kW lagega? Iska total kharcha kitna aayega, aur subsidy kaise milegi?

Iss blog mein hum step-by-step aapka confusion clear karenge.

Step 1: Ghar ka Load Estimate karo

Pehle aapko apne ghar ka approx daily unit consumption samajhna hoga. Neeche ek sample estimate diya gaya hai:

ApplianceUse per DayUnits per Day1.5 ton AC (x2)5 hours each~10 unitsRefrigerator24x7~1.5 unitsFan (6)10 hours~2 unitsLED Bulbs (10)6 hours~1 unitTV + Set Top Box3 hours~0.5 unitsWashing MachineAlternate Days~0.5 unitsWater Motor (0.5 HP)15 min/day~0.3 units

Total Daily Consumption: ~15–17 units/day
Monthly: ~450–500 units

Step 2: Kaunsa Solar System Size Sahi Rahega?

A 1kW system in Nalanda generates approx 4 units/day, considering local sunlight conditions.

So:

• 3kW = 12 units/day (Not enough for 2 ACs)
• 4kW = 16 units/day (Still borderline)
• ✅ 5kW = ~20 units/day (Best for 2 ACs + full home)

Final Recommendation:
5kW rooftop solar system is ideal for homes with:

• 2 Air Conditioners
• 1 Fridge
• Standard lights, fans, motor, etc.
  It also gives buffer for future load (e.g., second fridge or geyser).

Step 3: 5kW System Cost & Subsidy in 2025

Let’s break down the total cost in Nalanda:

DescriptionValue (INR)5kW Solar System MRP₹3,50,000PM Surya Ghar Subsidy₹78,000 (up to 3kW)Company Discount (GGS)₹20,000Final Price Payable₹2,52,000 approx

Note: Subsidy is available only up to 3kW.
5kW system par full subsidy nahi milti, but initial 3kW ke liye milta hai.

Step 4: EMI Option – Easy Monthly Payment

Agar aap ₹2.5 lakh ek saath nahi dena chahte, to 0% EMI option available hai.

DurationEMI Amount (Approx)12 mo₹21,000/month18 mo₹14,000/month24 mo₹10,500/month

Documents required:

• Aadhaar + PAN
• Latest Electricity Bill
• Cancelled Cheque or Bank Statement

Step 5: Roof Space Requirement

5kW system needs approx 500 sq. ft of shadow-free space.
Preferably south-facing or flat RCC roof.

If space is limited, you can go for:

• Elevated structure
• Partial system (3kW now, 2kW later)

Step 6: Installation Timeline in Nalanda

1. Free Site Survey
2. Subsidy application (PM Surya Ghar portal)
3. Approval from DISCOM (NBPDCL)
4. Installation (structure, panels, inverter)
5. Net Metering + Final handover

Total time: 10–15 working days

FAQs

Q1: Kya 3kW mein 2 AC chalega?
Answer: 1 AC ke liye 3kW theek hai, lekin 2 AC aur fridge ke liye 5kW better rahega.

Q2: Kya subsidy 5kW pe milegi?
Answer: Nahi. Subsidy sirf 3kW tak hi milti hai. 5kW system mein aapko first 3kW pe ₹78,000 tak subsidy milegi.

Q3: Kya system future mein upgrade ho sakta hai?
Answer: Haan, agar inverter scalable ho to baaki panels baad mein add kiye ja sakte hain.

Q4: Kya ghar ka बिजली बिल zero ho jayega?
Answer: Haan, agar aap 5kW system lagwate hain aur 500 units/month consume karte hain to bill almost zero ho sakta hai (sirf ₹100-₹200 net meter charge rahega).

Conclusion

Agar aap Nalanda mein 2 AC aur ek fridge ke saath high electricity bill face kar rahe hain, to ab waqt aa gaya hai switch karne ka. 5kW solar system aapko:

• ₹30,000+ annual saving
• ₹78,000 subsidy
• ₹2.5 lakh ke andar ka total cost
• 25 years ka peace of mind

Ghar Ghar Solar ke through aap pura system EMI pe bhi install karwa sakte hain — bina upfront cost ke.
