Benchmark Cost Analysis

System Costs: Solar vs. Solar + Battery in Wylie

You have two main paths when going solar in 2026. While a solar-only system offers a quicker payback, adding a battery provides critical backup power and stability against an unpredictable grid.

  • Solar-Only System (4kW): The upfront cost is around $11,500. After the 30% Federal Tax Credit, you're looking at a net cost of approximately $8,050. This option has a payback period of around 9-10 years.
  • Solar + Battery System: For complete energy security, a combined system costs roughly $23,500 upfront. The federal incentive brings this down to $16,450. While the payback extends to over 18 years based on savings alone, the real value comes from never being in the dark during an ERCOT power outage.

Incentives & Tax Credits

Tax Credits & Local Incentives

Texas homeowners benefit from some excellent financial perks. First and foremost is the 30% Federal ITC, which slashes your gross system cost. In addition, Texas has two state-level exemptions that help your investment: a 100% property tax exemption on the added value of your solar system and a full sales tax exemption on the equipment itself. This ensures you aren't penalized for improving your home's energy efficiency.

Navigating Net Metering in a Deregulated Market

Texas doesn't have a statewide net metering policy, which creates a different landscape than other states. Oncor manages the power lines, but your actual electricity plan comes from a Retail Electric Provider (REP). The key to maximizing solar savings is finding an REP that offers a competitive solar buyback plan. Some plans offer credits for your excess energy, while others don't. Before signing with a solar installer, it's critical to review your REP's specific solar policy.

Projected Savings

Calculating Your Monthly Electric Bill Savings

With an average electricity rate of $0.14/kWh in the Oncor service area, a standard 4kW system can generate about 6,131 kWh per year. This offsets a significant portion of a typical 1,000 kWh monthly bill, leading to annual savings of around $858. During the brutal Texas summer heat, those savings feel even bigger when the AC is running non-stop.

Local Questions Answered

Will my solar panels work during an ERCOT power outage?
Only if you have a battery. Standard grid-tied solar systems automatically shut down during an outage to protect utility workers. A solar-plus-battery system can isolate from the grid and use your stored solar energy to power your essential appliances.
How do solar panels hold up to Texas hail?
Modern solar panels are built to be incredibly durable. They are typically rated to withstand impacts from 1-inch hail at over 50 mph. While severe storms can occasionally cause damage, it's rare, and your homeowner's insurance policy usually provides coverage.
Do I need approval from Oncor to install solar?
Yes, you will need to submit an interconnection agreement through your installer to Oncor. They need to approve the system to ensure it's safe to connect to the grid. This is a standard part of the installation process.
