Solar Panel Cost FAQ - Kentucky

The cost of solar panels in Kentucky typically ranges from $2.50 to $3.50 per watt before incentives. For a standard 6 kW residential system, homeowners in Kentucky can expect to pay between $15,000 and $21,000 before the federal tax credit. After applying the 30% federal Investment Tax Credit, the net cost drops to approximately $10,500-$14,700. Actual costs vary based on your specific roof, chosen equipment, and installer. We recommend getting at least three quotes from local Kentucky solar installers to find the best price.

The average solar payback period in Kentucky depends on local electricity rates, available incentives, and sun exposure. Most Kentucky homeowners see a payback period between 6 and 10 years. After the payback period, you essentially enjoy free electricity for the remaining 15-20+ years of your system's life. Higher local electricity rates and additional state incentives can shorten the payback period significantly. A qualified Kentucky solar installer can calculate your specific payback period based on your energy usage and roof characteristics.

Kentucky homeowners who install solar panels typically save between $20,000 and $50,000 over 25 years, depending on system size, electricity rates, and available incentives. These savings come from reduced or eliminated electricity bills, net metering credits, and any applicable SREC income. As electricity rates in Kentucky continue to rise (historically averaging 2-3% annually), your savings grow each year. The combination of the 30% federal tax credit and any Kentucky-specific incentives helps maximize your return on investment.

The right solar system size for your Kentucky home depends on your electricity consumption, roof space, and budget. The average Kentucky home uses approximately 10,000-11,000 kWh per year, which typically requires a 6-8 kW solar system. To determine your ideal size, review your annual electricity usage on recent utility bills. Factors like Kentucky's average peak sun hours, your roof orientation, and any shading will affect how many panels you need. A professional Kentucky solar installer will use satellite imagery and your usage data to recommend the optimal system size.

Yes, solar is generally worth the investment for Kentucky homeowners in 2025. With solar panel costs at historic lows, the 30% federal tax credit still available, and electricity rates continuing to rise, the financial case for solar in Kentucky is strong. Most Kentucky homeowners who go solar see positive returns within 6-10 years, followed by 15-20+ years of significant savings. Additionally, solar panels increase your home value, provide energy independence, and protect against future electricity rate increases.
