Solar Power Size Calculator

For off-grid systems you can approximate your solar PV system wattage with this calculator:

1. What is the Total Power (Watts/W) your electronics will consume?
2. How long are you going to use these devices totally per day?

3. How long are you planning to use after full charging?

4. How many days are you planing to charge your battery fully?

5. What is your controller efficiency (PWM: 80%, MPPT: 90%)

6. What is the Average Sunshine Hours locally per day?

1. Minimum Solar Panel Size Recommended:

2. Minimum 12V Battery Volume Recommended:

3. Minimum 24V Battery Volume Recommended:
