Solar Panel Generation Formula:
| From: | To: |
The Solar Panel Generation formula calculates the total energy output from solar panels based on panel power, insolation, time period, and system efficiency. It provides an estimate of energy production for solar power systems.
The calculator uses the Solar Panel Generation formula:
Where:
Explanation: The formula calculates total energy output by multiplying panel power by daily insolation hours, then by number of days, and finally adjusting for system efficiency.
Details: Accurate energy calculation is crucial for sizing solar power systems, estimating energy production, calculating return on investment, and planning energy storage requirements.
Tips: Enter panel power in kW, insolation in hours per day, time period in days, and efficiency as a percentage. All values must be positive numbers.
Q1: What is typical solar panel efficiency?
A: Most commercial solar panels have efficiencies between 15-22%, with premium panels reaching up to 23-24%.
Q2: How is insolation measured?
A: Insolation is typically measured as peak sun hours per day, representing equivalent hours of full sunlight at 1000 W/m² intensity.
Q3: Does this account for system losses?
A: The efficiency factor should include all system losses including inverter efficiency, wiring losses, temperature effects, and soiling.
Q4: What is a good daily insolation value?
A: This varies by location. Typical values range from 3-6 hours per day depending on geographic location and season.
Q5: Can this be used for battery sizing?
A: Yes, the calculated energy output helps determine appropriate battery storage capacity for off-grid or backup power systems.
