How Carbon Footprint Calculation Works
Energy Generation
Daily generation = System Size × Peak Sun Hours × System Efficiency = 5kW × 5h × 80% = 20 kWh/day
Yearly: 20 kWh/day × 365 days = 7,300 kWh
CO2 Savings Calculation
CO2 saved = Energy Generated × Grid Carbon Intensity = 7,300 kWh × 0.82 kg/kWh = 5,986 kg CO2/year
Lifetime (with 0.5% annual degradation): 141.01 tons CO2 saved over 25 years
Environmental Equivalents
• Trees: 1 tree absorbs ~840 kg CO2 over 40 years → 1,41,005.93 kg ÷ 840 = 168 trees
• Cars: Average car emits 0.404 kg CO2/mile → 3,49,025 miles avoided
• Coal: 1 kg coal = 2.42 kg CO2 → 58,267 kg coal not burned
• Coal: 1 kg coal = 2.42 kg CO2 → 58,267 kg coal not burned
System Degradation
Solar panels degrade at ~0.5% per year. Lifetime calculation accounts for reduced output over 25 years.
Year 1: 100% → Year 25: ~88.67% efficiency
