Solar Energy Formula:
| From: | To: |
The solar energy calculation estimates the energy output of solar panels based on their capacity, annual sunlight hours, and system efficiency. It helps determine the potential energy production of solar installations in Canadian conditions.
The calculator uses the solar energy formula:
Where:
Explanation: The equation calculates the total energy output by multiplying the panel capacity by the number of sunlight hours and adjusting for system efficiency losses.
Details: Accurate energy estimation is crucial for sizing solar installations, calculating return on investment, and understanding the environmental benefits of solar power in the Canadian context.
Tips: Enter panel capacity in kW, annual sunlight hours, and system efficiency (typically 0.75-0.85 for most residential systems). All values must be positive numbers.
Q1: What is a typical efficiency value for solar systems?
A: Most residential solar systems have efficiencies between 75-85% (0.75-0.85) when accounting for inverter losses, temperature effects, and other factors.
Q2: How many sunlight hours can I expect in Canada?
A: This varies by region. Southern Canada typically gets 1,200-1,600 hours of effective sunlight annually, while northern regions may get 800-1,200 hours.
Q3: Does this account for seasonal variations?
A: The calculation uses annual averages. For more precise monthly estimates, you would need location-specific data for each month.
Q4: What factors affect solar panel efficiency?
A: Temperature, shading, panel orientation, dust/dirt accumulation, and system age all impact efficiency over time.
Q5: Can this calculator be used for commercial systems?
A: Yes, the same formula applies to both residential and commercial solar installations, though commercial systems may have different efficiency factors.
