1. What is a Peak Sun Hours Calculator for Australia?

Definition: This calculator estimates the equivalent peak sun hours based on total solar insolation data in Australia.

Purpose: It helps solar energy system designers and installers determine the effective sunlight hours for photovoltaic system sizing.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( PSH \) — Peak Sun Hours (hours)
• \( Total\ Insolation \) — Solar radiation received (Wh/m²/day)

Explanation: The total solar insolation is divided by 1000 W/m² (standard test condition for solar panels) to get equivalent peak sun hours.

3. Importance of Peak Sun Hours Calculation

Details: Accurate PSH calculation ensures proper solar system sizing, optimal energy production, and cost-effective system design.

4. Using the Calculator

Tips: Enter the total solar insolation value in Wh/m²/day (available from Australian solar maps or weather stations). Value must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: What is considered a good PSH value in Australia?
A: Most Australian locations range from 4-6 PSH, with northern regions typically higher than southern regions.

Q2: Where can I find insolation data for my location?
A: Use resources from the Bureau of Meteorology or Clean Energy Council solar maps.

Q3: Why divide by 1000?
A: Solar panels are rated at 1000 W/m² under standard test conditions, so this converts total energy to equivalent hours at peak sun.

Q4: Does this account for seasonal variations?
A: No, use monthly insolation data if you need season-specific calculations.

Q5: How does PSH affect solar system size?
A: Lower PSH values require larger systems to produce the same energy output as smaller systems in high PSH areas.
