- Use Case: Large-scale solar systems (10+ kW).
2. Installation Fees
- Professional Installation: PKR 10,000–30,000
- Includes labor costs for installing the battery, connecting it to the solar system, and ensuring proper wiring and safety measures.
- Additional Components: PKR 5,000–20,000
- Includes cables, connectors, mounting hardware, and other accessories required for installation.
3. Inverter Costs (if needed)
- Hybrid Inverter: PKR 50,000–150,000
- Required if your solar system does not already have an inverter compatible with lithium batteries.
- Off-Grid Inverter: PKR 30,000–100,000
- Suitable for off-grid solar systems.
4. Maintenance Costs
- Annual Maintenance: PKR 5,000–10,000
- Includes routine checks, cleaning, and performance monitoring to ensure the battery operates efficiently.
Total Cost Estimate
| Component | Cost Range (PKR) | Notes |
|---|---|---|
| Lithium Battery | 40,000–350,000 | Depends on capacity and brand. |
| Installation Fees | 10,000–30,000 | Includes labor and additional components. |
| Inverter (if needed) | 30,000–150,000 | Required for new or incompatible systems. |
| Maintenance | 5,000–10,000 (annual) | Routine checks and performance monitoring. |
Factors Affecting Total Cost
