This tool helps you calculate how much energy you can generate from solar panels based on your location and panel size.
How to Use the Solar Calculator
To use this calculator, enter the following values:
- Solar Panel Capacity: The power rating of your solar panel in watts (W).
- Average Sunlight Hours per Day: The average number of sunlight hours your location receives per day.
- Panel Efficiency: The efficiency of your solar panels (as a percentage, e.g., 18 for 18%).
- System Losses: The percentage of system losses due to various factors like shading, inverter loss, etc.
After filling in all the fields, click the “Calculate” button to see the estimated daily energy production in watt-hours (Wh).
Calculation Methodology
The calculator uses the following formula to calculate the daily energy production:
Daily Energy Production (Wh) = Solar Panel Capacity (W) × Average Sunlight Hours × Panel Efficiency (%) × (1 – System Losses (%))
Where:
- Solar Panel Capacity (W): The power output rating of the solar panel.
- Average Sunlight Hours: The average amount of time the panel receives direct sunlight.
- Panel Efficiency (%): The conversion efficiency of the solar cells in the panel.
- System Losses (%): The percentage of power loss due to factors like temperature, shading, and equipment inefficiencies.
Limitations
Please note that this calculator provides an estimate based on the values entered. Actual energy production can vary due to factors such as:
- Weather conditions
- Seasonal variations
- Shading from nearby objects
- Dirt and debris accumulating on the panels
- Degradation of panel efficiency over time
Always consult a solar energy professional for detailed analysis and precise calculations tailored to your specific circumstances.
