Comprehensive Guide to Photovoltaic System Sizing
Designing a reliable solar power system requires a precise evaluation of electrical parameters, geographic variables, and load specifications. This advanced calculator provides accurate architectural specifications for standalone or hybrid photovoltaic arrays.
Formula Used
- Solar Array Peak Power: $\text{Array Power} = \frac{\text{Daily kWh}}{\text{Peak Sun Hours} \times \text{Efficiency}} \times \text{Safety Factor}$
- Battery Bank Capacity: $\text{Capacity (Ah)} = \frac{\text{Daily kWh} \times 1000 \times \text{Days of Autonomy}}{\text{Battery Voltage} \times \text{DoD}}$
- Inverter Rating: $\text{Inverter kW} = \text{Peak Load kW} \times \text{Inverter Safety Margin}$
How to Use This Calculator
Input your daily energy consumption in kilowatt-hours, determine your local peak sun hours, select individual component ratings, and click calculate to view immediate metrics.
Frequently Asked Questions
What are peak sun hours? Peak sun hours represent the equivalent number of hours per day when solar irradiance averages 1,000 watts per square meter.
Why is a safety factor necessary? Safety factors compensate for environmental degradation, temperature variations, and dust accumulation on panels.
