How Many Watts of Solar Panels Do You Need for 220V Systems? | EK SOLAR Guide
Understanding Solar Panel Requirements for 220V Applications
Wondering how to power your 220V devices with solar energy? The answer lies in understanding three key factors: daily energy consumption, sunlight availability, and system efficiency. Let's break it down with real-world examples and actionable calculations.
Key Components of a 220V Solar System
- Solar panels (monocrystalline or polycrystalline)
- MPPT charge controller
- 48V battery bank
- 3000W pure sine wave inverter
Pro Tip: Always add 20-30% extra capacity to account for system losses and future expansion.
Wattage Calculation Formula
Use this simple equation to estimate your solar needs:
Total Watts = (Daily kWh ÷ Sun Hours) × 1,000 × 1.3
Real-World Example: Home Appliances
| Appliance | Power (W) | Daily Use | Solar Panels Needed* |
|---|---|---|---|
| Refrigerator | 150 | 24h | 4×400W |
| Air Conditioner | 1,500 | 8h | 8×400W |
*Based on 5 peak sun hours daily
