Evaluating Rooftop Solar in Windsor for 2026
For homeowners in Windsor, the combination of high Front Range sun exposure and rising electricity costs makes solar a compelling option. With Xcel Energy rates at $0.163/kWh, many are looking for ways to lower their monthly bills. The key question is whether the upfront investment pays off, especially now that the major federal tax credits have expired. The answer lies in Colorado's excellent state-level policies and the strong performance of solar panels in our climate.

What Do Solar Panels Cost in Windsor?
A residential solar system sized to offset a typical Windsor electricity bill is around 6.5 kW. In early 2026, the all-in cost for an installed system of this size is approximately $17,875.
- Typical System Size: 6.5 kW
- Estimated Net Cost: $17,875
- Average Cost per Watt: $2.75
For those interested in backup power during grid outages, a 10 kWh battery can be added, bringing the total system cost to around $32,875. However, since Xcel's net metering program already provides full value for your excess solar energy, a battery doesn't shorten the financial payback period; its value is primarily in providing resilience.
Incentives & Tax Credits
Key Colorado Solar Incentives (2026)
Even without a federal tax credit, the economics for solar in Windsor are supported by strong state policies that directly benefit homeowners:
- Property Tax Exemption: Installing solar panels adds value to your property, but thanks to Colorado law, it won't increase your property tax assessment. This is a significant, guaranteed benefit.
- Sales Tax Exemption: You won't pay Colorado's state sales tax on your solar panels, batteries, or installation hardware, lowering the total upfront cost.
- Owned System Resale Value: An owned solar system can be an attractive feature for potential home buyers, who value the benefit of lower, more predictable energy bills.
Net Metering: Xcel Energy

Understanding Net Metering with Xcel Energy
The financial success of rooftop solar in Windsor hinges on Xcel Energy's net metering program. This policy allows you to get full retail value for any surplus electricity your system generates. During a sunny afternoon, your panels might produce more power than you need. That excess energy is sent to the grid, and Xcel credits your account at the same rate ($0.163/kWh) you would normally pay. These credits cover the cost of electricity you use from the grid later, like at night. This 1-to-1 exchange is what makes the payback period so attractive.
Projected Savings
Potential Solar Savings in Windsor
A 6.5 kW solar installation in Windsor is estimated to produce enough power to save an average household $1,227 per year. This leads to a straightforward payback period of about 12.0 years. After the system has paid for itself, it continues to generate free electricity for another 15 years or more. This acts as a powerful hedge against inflation—if Xcel Energy's rates climb in the future, the value of the electricity you generate at home increases right along with them, making your initial investment even more valuable.
