A Way to Stabilize Your Public Service Co of Colorado Bills
For homeowners in Louisville, rooftop solar offers a powerful way to gain predictability over electricity costs. With utility rates subject to change, generating your own power provides a hedge against future price increases. Colorado's abundant sunshine and strong consumer protection policies make solar a viable financial tool, even with the phase-out of the federal residential tax credit for systems installed in 2026.

2026 Solar Installation Costs in Louisville
The estimated upfront cost for a 6.7 kW solar-only system in Louisville is $18,425. This price reflects the market in early 2026, after the conclusion of the federal residential clean energy credit. This is the total cost before any local utility rebates that may be available.
- Solar-Only System (6.7 kW): $18,425
- Solar + Battery System (6.7 kW panels with a 10 kWh battery): $33,425
Adding a battery provides valuable backup during power outages but is not financially necessary for savings under Xcel's current net metering rules. It increases the payback period to nearly 20 years, making it a choice for resilience rather than pure economics.
Incentives & Tax Credits
Key Colorado Benefits for Solar Owners
While the federal tax credit has ended for new 2026 installations, Colorado provides crucial state-level incentives that reduce the financial burden and enhance the value of going solar:
- No Sales Tax on Equipment: Homeowners are exempt from paying state sales tax on solar panels and associated equipment, which lowers the initial purchase price.
- Property Tax Exemption: Your home's assessed value will not increase due to the addition of a solar panel system. This means you gain the long-term asset of an energy-producing system without a corresponding rise in your property tax bill. An owned solar system can also be a significant selling point, adding to your home's resale appeal.
Net Metering: Public Service Co of Colorado

Understanding Net Metering with Public Service Co of Colorado (Xcel)
Louisville homeowners with solar connect to the grid under Xcel Energy's net metering program. This arrangement is simple and effective: your meter tracks both the electricity you draw from the grid and the excess electricity your panels send to it. For every unit of power you export, you receive a full retail-rate credit on your bill. These credits cover the cost of power you use at night or on overcast days, effectively letting you use the grid as a storage solution for your excess solar energy. This 1-for-1 exchange is what makes solar financially attractive without requiring a battery for bill optimization.
Projected Savings
How Much Can You Save on Electricity in Louisville?
A 6.7 kW solar system, sized for a typical home in Louisville, is estimated to produce $1,227 in electricity savings during its first year. This production is designed to offset an average monthly electric bill of around $122.25 from Public Service Co of Colorado (Xcel Energy).
With these savings, the system's payback period is approximately 12.3 years. After this point, the electricity generated is pure savings for the life of the system, which is typically warrantied for 25 years. This long-term value is especially important; as grid electricity costs rise, the savings from your fixed-cost solar system grow larger each year.
