Energy storage bridges the gap between solar generation and consumption, especially during Pakistan’s frequent load‑shedding periods.
Why Store Solar Energy?
Storing excess daytime solar power enables you to use it at night, during cloudy periods, or when the grid is down. It also helps reduce reliance on diesel generators.
Battery Technologies Overview
| Technology | Energy Density | Cycle Life | Cost (PKR/kWh) | Typical Use Case |
|---|---|---|---|---|
| Lead‑Acid (Flooded) | Low | 500‑800 cycles | 30,000‑40,000 | Backup only, low cost |
| Lead‑Acid (AGM/GEL) | Medium | 800‑1200 cycles | 35,000‑45,000 | Small residential, limited depth‑of‑discharge |
| Lithium‑Ion (NMC) | High | 3000‑5000 cycles | 80,000‑120,000 | Premium residential, high efficiency |
| Flow Battery | Very High (scalable) | 10,000+ cycles | 150,000‑200,000 | Commercial, long‑duration storage |
Choosing the Right Battery for Your Home
- Budget Constraints – Lead‑acid offers the lowest upfront cost but requires more maintenance.
- Space Availability – Lithium packs are compact, suitable for limited indoor spaces.
- Depth of Discharge (DoD) – Lithium systems can safely discharge 80‑90% of capacity, maximizing usable energy.
- Safety and Maintenance – Lithium batteries are sealed and require minimal upkeep.
Solarium360 Battery Selection Process
- Load Evaluation – Determine nightly consumption and desired backup duration.

Installation & Warranty
Our certified technicians install battery racks, integrate them with the inverter, and set up monitoring dashboards. All battery packs come with a minimum 5‑year warranty, with optional extensions.
Case Study: 10 kWh Lithium System in Karachi
A family with a 6 kW rooftop system added a 10 kWh lithium‑ion battery. They now experience uninterrupted power for up to 8 hours during load‑shedding, saving about PKR 12,000 per month on generator diesel.
Final Thoughts
Battery storage transforms solar from a daytime-only solution into a 24‑hour power source. Contact Solarium360 to assess your home’s needs and receive a tailored storage proposal.
