Frequently Asked Questions
Common questions about going solar in Lewisville
Yes, solar is typically an excellent investment in Lewisville. With 5.2 peak sun hours daily—higher than the national average—and Oncor charging $0.148/kWh, most homeowners see payback periods of 7-10 years. After that, you're generating free electricity for another 15-20 years. The 30% federal tax credit through 2032 further improves the ROI.
Savings depend on your current electricity usage. A Lewisville home with a $180/month electric bill can typically save $40,000-$60,000 over 20 years. These savings account for Oncor's current rates, historical rate increases of 3% per year, and system degradation of 0.5% annually.
Texas doesn't have statewide solar rebates, but the federal Investment Tax Credit (ITC) provides a 30% credit on your total system cost through 2032. This means a $20,000 system costs effectively $14,000 after the tax credit. Some Oncor programs may offer additional incentives—we recommend checking their current offerings.
System size depends on your electricity consumption. For a typical Lewisville home paying $180/month, you'd need approximately 8-10kW of solar panels. Our calculator above provides a personalized estimate based on your actual monthly bill and Oncor's rates.
Modern solar panels are designed to withstand extreme temperatures and typically last 25-30 years. While Texas heat can slightly reduce efficiency on the hottest days, the abundant sunshine more than compensates. Most manufacturers offer 25-year production warranties, guaranteeing at least 80% output over that period.
Standard grid-tied solar systems shut off during outages for safety reasons (to protect utility workers). If backup power is important to you, consider adding a battery storage system like Tesla Powerwall or Enphase IQ. This allows you to store solar energy and maintain power during Oncor outages.
Texas has net metering policies that vary by utility. With Oncor, excess energy you generate is typically credited to your account, offsetting future usage. The exact rate and terms depend on your specific plan—our local analysts can help you understand your options.
Studies consistently show solar panels increase home values. According to Zillow, homes with solar sell for approximately 4.1% more on average. In Lewisville, where the median home value is $350,000, this could mean an additional $14,350 in resale value.
