Solar Inverter Calculator
Calculate solar inverter performance, energy output, efficiency, and return on investment for residential and commercial solar systems.
Step 1: System Specifications
Energy Production Formula
Daily Energy (kWh) = Solar Capacity (kW) × Sunlight Hours × Efficiency
Annual Energy = Daily Energy × 365 days
Step 2: System Configuration
Typical System Sizes
Residential: 3-10 kW
Small Commercial: 10-50 kW
Large Commercial: 50-500 kW
Utility Scale: 500+ kW

Financial Analysis & ROI
Return on Investment Calculation
Payback Period = System Cost ÷ Annual Savings
ROI = (Annual Savings × System Lifetime) ÷ System Cost
Typical residential solar system: $15,000-$25,000
Typical commercial system: $50,000-$200,000+
Incentives & Rebates
Common Solar Incentives
• Federal Tax Credit: 26-30% of system cost
• State Rebates: Varies by location
• Net Metering: Credit for excess energy
• SRECs: Solar Renewable Energy Certificates
• Property Tax Exemptions: In many states
