📚 About Solar Calculators

How It Works

•Uses real sunrise/sunset data from your location
•Calculates peak sun hours based on latitude
•Accounts for system efficiency, shading, and tilt
•Provides seasonal production breakdown
•Includes 30% federal tax credit (2024)

Key Factors

•Location: Determines sun exposure
•Panel Quality: 15-22% efficiency typical
•Tilt Angle: Optimal = latitude angle
•Shading: Even partial shade reduces output
•System Losses: 15% typical (85% efficiency)
