2026 Solar Panel Installation Costs in Longview
For a typical home in the Longview area, a professionally installed solar energy system has a clear price point. These figures are based on a system designed to offset the majority of an average household's electricity usage.

Incentives & Tax Credits
Key Financial Incentives for Longview Solar Owners
Even without a federal tax credit in 2026, Texas offers a major benefit that makes going solar more affordable:
- Texas Property Tax Exemption: This is the cornerstone of solar incentives in the state. Your home's assessed value will not increase because of your solar installation, meaning you will not pay additional property taxes on the system. This provides thousands of dollars in value over the life of the panels.
There are no state-level tax credits or rebates. The financial case for solar in Longview rests on the property tax exemption and the direct reduction in your monthly electricity costs. An owned solar system can also be a valuable asset, potentially improving your home's appeal to future buyers.
Net Metering: Address-specific utility or retail electricity plan
Limited Export Credit
Optional
Exporting Power in Texas: What You Need to Know
Unlike some states, Texas has no universal net metering law. The value of the excess electricity your panels produce and send to the grid is determined entirely by your Retail Electricity Provider (REP). In most cases, the buyback rate is far below the retail rate you pay for electricity.
This reality makes self-consumption the most important factor for solar savings. Your goal should be to use as much of your own solar power as possible. This is why adding a battery, while optional, often makes financial sense. It allows you to store your cheap, clean solar energy from the afternoon and use it during the evening peak hours.
Projected Savings
How Solar Reduces Your Monthly Electric Bill
Your solar panels generate electricity that your home uses first, directly offsetting power you would have otherwise purchased from the grid. Based on local solar conditions and utility rates, the financial impact is significant.
- A solar-only system is projected to save an estimated $1,181 in the first year, resulting in a payback period of about 18.2 years.
- By adding a 10 kWh battery, first-year savings increase to an estimated $1,855, which improves the payback to around 16.6 years.
The battery enhances savings by ensuring you use more of your own solar power, rather than exporting it for low credits. This strategy also provides a buffer if utility rates climb in the future, as your self-generated power will offset increasingly expensive grid electricity.
