Solar Panel Calculator

This interactive tool helps you estimate the number of solar panels required to power your home or business based on your energy consumption, location, and panel efficiency. It provides a clear breakdown of costs, savings, and environmental impact.

How to Use:

• Enter your average monthly electricity usage (in kWh).
• Select your location to account for sunlight hours.
• Input the wattage of the solar panels you're considering.
• Adjust for system efficiency (typically 75-85%).

Example Calculation:

For a home using 900 kWh/month in California (5 peak sun hours/day) with 400W panels at 80% efficiency:

Key Outputs:

• Estimated number of panels required
• Total system cost (with adjustable $/watt)
• Annual electricity production
• Payback period
• CO2 emissions reduced

Note: This calculator provides estimates only. Actual performance may vary based on installation angle, shading, weather patterns, and other factors. Consult with a solar professional for precise calculations.

Advanced Features: Some versions may include battery storage calculations, financing options, or comparison tools between different panel types.
