1. What is Solar Insolation?

Solar insolation refers to the amount of solar radiation energy received on a given surface area during a specific time period. It is a crucial factor in determining the efficiency and output of solar panel systems.

2. How Does the Calculator Work?

The calculator uses the insolation formula:

Where:

• \( Latitude\;Factor \) — Location-based solar radiation multiplier
• \( Day\;Length \) — Duration of sunlight hours per day

Explanation: The formula calculates daily solar energy potential by combining geographical location efficiency with available sunlight duration.

3. Importance of Insolation Calculation

Details: Accurate insolation calculation is essential for sizing solar power systems, estimating energy production, and optimizing solar panel placement and orientation.

4. Using the Calculator

Tips: Enter latitude factor (typically 0.6-1.2 depending on location) and day length in hours. Both values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What is a typical latitude factor range?
A: Latitude factors typically range from 0.6 (higher latitudes) to 1.2 (equatorial regions), representing solar radiation intensity variation.

Q2: How does season affect insolation?
A: Insolation varies significantly with seasons due to changes in day length and sun angle, with summer months typically having higher values.

Q3: What is considered good daily insolation?
A: Good insolation is typically 4-6 kWh/m²/day, while excellent conditions can reach 6-8 kWh/m²/day in optimal locations.

Q4: How accurate is this calculation?
A: This provides a basic estimate. For precise solar system design, consider additional factors like weather patterns, shading, and panel efficiency.

Q5: Can this be used for off-grid systems?
A: Yes, this calculation helps determine battery storage needs and panel sizing for off-grid solar installations.
