Backend Formula for the Energy Yield Calculator
The Energy Yield Calculator relies on a fundamental formula that considers several variables:
- Energy Yield (kWh) = System Capacity (kW) × Annual Solar Irradiance (kWh/m²) × Performance Ratio
Each component plays a critical role:
- System Capacity: The maximum output capacity of the system, usually measured in kilowatts (kW).
- Annual Solar Irradiance: The total solar energy received per square meter over a year, influenced by location and weather patterns.
- Performance Ratio: A coefficient reflecting system efficiency, accounting for losses due to temperature, shading, and equipment inefficiencies.
For example, consider a 5 kW solar system located in an area with an annual solar irradiance of 1600 kWh/m² and a performance ratio of 0.8. The estimated energy yield would be 6400 kWh per year.
Alternative formulas may adjust for specific conditions, such as incorporating seasonal variations or advanced loss factors, enhancing precision for particular applications.
