Battery Storage — Do You Really Need It?

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.

How Much Battery Do You Need?

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
