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. This standardized measurement helps calculate solar energy production regardless of location.
- 1 peak sun hour = 1 hour of 1,000 W/m² sunlight
- Different from actual daylight hours
- Varies by season and location
- Essential for sizing solar systems
Why Sun Hours Matter
Understanding your location’s sun hours helps optimize solar energy systems:
- Accurately size solar panel systems
- Estimate energy production and ROI
- Determine battery storage requirements
- Compare locations for solar viability
- Optimize panel orientation and tilt
Regions with more peak sun hours generate more solar energy per panel.
Increasing Solar Production
Maximize your solar energy yield with these tips:
- Optimize panel angle for your latitude
- Face panels true south (northern hemisphere)
- Keep panels clean and unobstructed
- Use micro-inverters for shaded areas
- Consider solar tracking systems
Proper installation can increase energy production by 10-25%.
Frequently Asked Questions
What are sun hours in kWh?
Sun hours in kWh refer to the amount of solar energy received at a specific location. One peak sun hour equals 1,000 watt-hours (1 kWh) of solar energy per square meter. This measurement helps calculate how much electricity a solar panel system can produce in your location.
Is there a sun hours calculator app?
Yes, there are several apps available for calculating sun hours. Our web-based calculator is mobile-friendly and works like an app on your smartphone. Simply enter your location or use GPS to get instant peak sun hour data without downloading anything.
How do I calculate peak sun hours?
Peak sun hours are calculated by converting solar irradiance data into equivalent hours of peak sunlight. Our calculator uses your location’s latitude, longitude, and historical solar data to determine average daily peak sun hours. The formula: Peak Sun Hours = Total Daily Solar Insolation (kWh/m²) ÷ 1 kW/m².
How do I find peak sun hours by location?
You can find peak sun hours by location using our calculator. Enter your address, ZIP code, or use your current location. We access solar databases to provide accurate peak sun hour data specific to your geographical coordinates.
