Benchmark Cost Analysis

2026 Solar & Battery Installation Costs

Getting those savings requires an upfront investment, but federal and state incentives make it highly manageable.

  • A solar-only system, sufficient to generate these savings, typically costs about $11,500 before incentives. After the 30% federal tax credit, the final cost to you is around $8,050, delivering a payback of about 9 years.
  • For total energy resilience, adding a home battery for outage protection raises the initial cost to $23,500, or $16,450 after the tax credit. This is the choice for homeowners who prioritize uninterrupted power.

Incentives & Tax Credits

Making Solar Affordable: Credits and Exemptions

The primary driver of affordability is the 30% Residential Clean Energy Credit, a direct dollar-for-dollar reduction of your federal income taxes. In Colorado, you also benefit from a complete sales tax exemption on the purchase of your system and a property tax exemption. This means that while solar panels add significant value to your home, your property tax bill won't increase as a result.

The Key to Savings: Xcel's Full Retail Net Metering

Unlike states that have weakened their solar programs, Colorado's net metering law remains incredibly favorable for homeowners. Here’s how it works for you in Lafayette: for every unit of excess electricity your panels produce and send to the grid, Xcel Energy gives you a one-for-one credit. This means the kilowatt-hours you export during a sunny afternoon are worth the same as the ones you import from the grid at night. This simple, fair exchange is what makes solar pencil out so well here.

Projected Savings

Expected Yearly Savings in Lafayette

Leveraging that powerful net metering policy translates directly into cash savings. A system sized to meet the needs of a typical home using 750 kWh per month will eliminate around $879 in electricity costs per year. Over the 25-year warranty of your panels, that adds up to over $21,975 in savings, protecting your family from decades of unpredictable utility rate increases.

Local Questions Answered

How big of a solar system do I need for my Lafayette home?
A 4 kW system is a good starting point for a home with a $109 monthly electric bill. However, the ideal size depends on your actual yearly energy consumption, roof space, and orientation. Our calculator can provide a more precise recommendation.
Will Lafayette's sometimes cloudy weather affect my solar production?
While clouds do reduce output, Colorado's high altitude and 300+ sunny days a year more than compensate. Panels still produce energy on overcast days from indirect light. Annual production estimates always account for local weather patterns.
What's the difference between Xcel's net metering and what's happening in California?
Colorado has true net metering (1-for-1 credit). California has switched to a 'net billing' system where they pay homeowners a much lower wholesale rate for exported energy. This makes solar far more valuable in Colorado today and is a major reason to consider it now.
