Solar Energy Formula:
| From: | To: |
The solar energy calculation estimates the amount of energy a solar panel system can produce based on location-specific insolation, panel area, and system efficiency. It provides a practical assessment of potential energy generation for solar installations.
The calculator uses the solar energy equation:
Where:
Explanation: The equation calculates daily energy production by multiplying the solar radiation available at a location by the panel area and the system's efficiency factor.
Details: Accurate solar energy estimation is crucial for sizing solar power systems, evaluating economic viability, and planning energy production for residential, commercial, and utility-scale installations.
Tips: Enter insolation in kWh/m²/day, area in square meters, and efficiency as a decimal between 0 and 1. All values must be valid positive numbers.
Q1: What is typical insolation value for my location?
A: Insolation values vary by geographic location and season. Typical values range from 3-7 kWh/m²/day depending on climate and latitude.
Q2: What efficiency values are realistic for solar panels?
A: Modern solar panels typically have efficiencies between 15-22%, while complete system efficiencies accounting for inverters and other components are usually 12-18%.
Q3: How does panel orientation affect energy production?
A: Optimal orientation (south-facing in northern hemisphere) maximizes energy production. Deviations from optimal orientation can reduce output by 10-25%.
Q4: Are there limitations to this calculation?
A: This simplified calculation doesn't account for temperature effects, shading, panel degradation over time, or seasonal variations in sun angle.
Q5: Should this calculation be used for system sizing?
A: For precise system sizing, professional solar assessments that include detailed shading analysis and local weather patterns are recommended.
