The most expensive part of a solar system isn't the panels — it's the battery. A single LiFePO4 battery adds ₱26,000 to ₱100,000+ to your system cost.
| Feature | Grid-Tied | Hybrid |
|---|---|---|
| Upfront cost (5kW) | ₱180K - ₱230K | ₱280K - ₱350K |
| Works during blackouts | No | Yes |
| Net metering | Yes | Yes |
| Payback period | 2.5 - 3.5 years | 3.5 - 5 years |
| Maintenance | Almost zero | Battery replacement in 10-15 years |
| Brand | Model | Capacity | Price | ₱/kWh |
|---|---|---|---|---|
| Pylontech | US2000C | 2.4 kWh | ₱26,000 | ₱10,833 |
| Pylontech | US3000C | 3.5 kWh | ₱43,000 | ₱12,286 |
| HIGEE | 48V 100Ah | 4.8 kWh | ₱51,500 | ₱10,729 |
| Pylontech | US5000C | 4.8 kWh | ₱62,500 | ₱13,021 |
| LvTopSun | 51.2V 200Ah | 10.24 kWh | ₱72,500 | ₱7,080 |
| Dyness | DL5.0C | 5.12 kWh | ₱65,000 | ₱12,695 |
Lower ₱/kWh = better value. LvTopSun 200Ah offers the best value per kWh.
Total nighttime load (watts) × hours needed ÷ 0.8 (depth of discharge) = required Wh
Example: 500W load × 8 hours ÷ 0.8 = 5,000 Wh = 5 kWh battery
