जानिए 2025 में भारत में solar battery price per kWh, lead acid vs lithium battery cost comparison, capacity (Ah vs kWh), installation, warranty, usability और best options for homes.
Introduction – Solar Battery Price per kWh kya hota hai?
Solar batteries solar systems ke liye backup power storage units hote hain — jo solar energy ko store karke power cut, rainy season aur night time usage ke liye use kiya jata hai.
Isliye inverter ke saath solar battery lena un jagah important hai jahan electricity backup ki zaroorat hai — jaise rural areas, frequent power cuts wale zones, ya off-grid/hybrid systems.
“Solar battery price per kWh” iska measure batata hai ki battery 1 unit (1 kWh) storage capacity ke liye kitne me milti hai. Ye figure help karta hai accurate system cost estimate aur ROI calculation me.
🟩 2. Battery Storage Basics — Ah vs kWh (Simple Explanation)
Solar batteries ki capacity do tarike se measure hoti hai:
🔹 Ah (Ampere-hour):
Ye batata hai battery ek fixed voltage per kitna current store kar sakti hai.
Example: 150 Ah battery at 12 V = 12 × 150 / 1000 = 1.8 kWh capacity
🔹 kWh (Kilowatt-hour):
Ye showing true usable power in kWh — easiest way to measure storage.
Conversion:
Battery kWh = (Voltage × Ah) ÷ 1000
Example:
24 V × 100 Ah = 2400 Wh = 2.4 kWh
🟩 3. Solar Battery Types & Price per kWh (2026)
Solar batteries commonly 3 types me milti hain — cost aur performance alag-alagat hota hai:
| Battery Type | Typical Price per kWh (₹) | Notes |
|---|---|---|
| Lead-Acid Tubular | ₹5,000 – ₹7,000 | Affordable, moderate life |
| Lithium LiFePO₄ | ₹8,000 – ₹15,000 | Premium, long life |
| Gel / AGM | ₹6,000 – ₹8,000 | Sealed, maintenance-free |
👉 Price difference battery chemistry, warranty, brand aur capacity par depend karta hai.
🟩 4. India 2026 – Solar Battery Price per kWh Breakdown
🔹 Lead-Acid Solar Batteries

➡ Approx price per kWh ~ ₹5,000 – ₹7,000
Lead-acid common aur budget option hai lekin lifespan (3–5 yrs) limited hota hai.
🔹 Lithium Solar Batteries
- 24 V | 100 Ah → ~2.4 kWh | ₹18,000 – ₹30,000
- 48 V | 100 Ah → ~4.8 kWh | ₹36,000 – ₹60,000
➡ Approx price per kWh ~ ₹8,000 – ₹15,000
Lithium technology fast charging, maintenance-free aur long life (8–12 yrs) deti hai. Premium systems me lithium most preferred choice hai.
🔹 Gel / AGM Solar Batteries
- 12 V | 150 Ah → ~1.8 kWh | ₹10,000 – ₹14,000
- 12 V | 200 Ah → ~2.4 kWh | ₹14,000 – ₹18,000
➡ Approx price per kWh ~ ₹6,000 – ₹8,000
Gel/AGM sealed batteries maintenance-free hoti hain and often used in hybrid/off-grid setups.
🟩 5. Why Solar Battery Price per kWh Varies
📍 Battery Chemistry
Lead-acid ➡ lowest cost
Lithium ➡ highest performance + cost
Gel/AGM ➡ mid-range
📍 Voltage Configuration
Higher voltage battery banks (24 V / 48 V) cost per kWh differ karte hain.
📍 Brand & Warranty
Top brands premium cost lete hain extended warranty ke liye.
📍 Cycle Life (number of cycles)
Higher cycle life ➡ higher price per kWh
📍 Market Supply & Demand
Global battery raw material cost se bhi influence hota hai.
