Solar Load Formula:
| From: | To: |
Solar load represents the amount of power generated or received from solar radiation, calculated by multiplying irradiance (solar power per unit area), the area of the solar panel or surface, and the efficiency of energy conversion.
The calculator uses the solar load formula:
Where:
Explanation: This formula calculates the actual power output or energy received from a solar system based on available sunlight, system size, and conversion efficiency.
Details: Accurate solar load calculation is essential for designing solar power systems, estimating energy production, sizing system components, and evaluating the economic viability of solar installations.
Tips: Enter irradiance in W/m², area in m², and efficiency as a decimal value between 0 and 1. All values must be positive numbers.
Q1: What is typical irradiance value?
A: Standard test conditions use 1000 W/m², but actual values vary by location, time of day, and weather conditions.
Q2: How do I determine system efficiency?
A: Efficiency depends on solar panel type, temperature, and system losses. Commercial panels typically range from 15-22% efficiency.
Q3: Can this calculator be used for thermal systems?
A: Yes, but the efficiency factor would represent thermal conversion efficiency rather than electrical conversion efficiency.
Q4: What factors affect solar irradiance?
A: Geographic location, time of year, time of day, weather conditions, and atmospheric clarity all impact solar irradiance levels.
Q5: How accurate is this calculation for real-world applications?
A: This provides a basic estimate. Professional solar design requires more detailed analysis including temperature coefficients, tilt angles, shading, and system losses.
