Estimated Solar Panel Costs in Lafayette (2026)
The upfront cost is the first number most homeowners consider. For a typical home in Lafayette, a 6.7 kW solar panel system is estimated to cost around $18,425. This price reflects the full installation before any savings are applied.
What About a Solar Battery?
Adding a home battery for backup power is an option, but it significantly increases the cost. A combined solar and battery system would be closer to $33,425. Because Colorado offers strong net metering, a battery isn't necessary to achieve bill savings; its primary value is providing power during a grid outage.
Incentives & Tax Credits
Colorado's Pro-Solar Policies Make a Difference
While the 30% federal tax credit for systems placed in service is no longer the default for homeowners in 2026, Colorado provides significant state-level advantages that support a strong return on investment:
- Property Tax Exemption: Installing solar panels adds value to your home, but Colorado law exempts this added value from your property tax assessment. You get the benefit without the higher tax bill.
- Sales and Use Tax Exemption: You won't pay state sales tax on your solar panels, batteries, or installation hardware, which directly reduces the total upfront cost of the project.
- Strong Net Metering: This is the most critical financial incentive. Public Service Co of Colorado's program ensures you get full value for the excess power you produce.
Beyond direct savings, an owned solar system can also be a compelling feature for potential buyers, potentially supporting your home's resale appeal.

Understanding Net Metering with Public Service Co of Colorado
Colorado's net metering policy is a major reason solar remains financially viable. Here’s how it works: when your solar panels produce more electricity than your home is using, the excess power flows to the grid. Public Service Co of Colorado credits your account for this energy at the full retail rate—the same price you pay for electricity. These credits are then used to offset the cost of the electricity you draw from the grid at night or on cloudy days. This 1-for-1 exchange maximizes the value of every kilowatt-hour your system generates.
Projected Savings
How Solar Creates Long-Term Value
A 6.7 kW system in Lafayette is modeled to produce approximately $1,227 in electricity savings in its first year. This translates to a payback period of about 12.3 years. After the system has paid for itself, the electricity it generates is essentially free for the life of the panels, which are typically warrantied for 25 years. Solar is not only about today's bill; if grid electricity from Public Service Co of Colorado becomes more expensive over time, rooftop generation can offset costlier power in future years, making your investment even more valuable.
