Navigating Net Metering & REPs in East Texas

Longview is in a deregulated electricity market. This means you must choose a Retail Electric Provider (REP) that offers a good solar buyback plan. Some REPs offer near retail rate credit for your excess solar, while others offer much less. Researching plans from providers like TXU Energy, Rhythm, or Green Mountain Energy is critical to maximizing your savings. A solar battery simplifies this, as you can store and use your own energy, making you less dependent on the buyback rate your REP offers.

Projected Savings

What Are the Monthly Solar Savings in Longview?

With an average electricity rate of $0.14 per kWh from various Retail Electric Providers (REPs), a 4 kW solar system is projected to save a Longview household about $819 per year. Over the 25-year warrantied life of the panels, that amounts to over $20,000 in savings, shielding you from the inevitable rate increases in the Texas electricity market.

Local Questions Answered

Which REP has the best solar buyback plan in Longview?
Solar buyback plans change frequently. It's essential to check current offers when you're ready to install. Look for plans that offer a 1:1 credit or a fixed-rate buyback. Your solar installer can often help you find the most favorable plan.
How does the East Texas humidity affect solar panels?
High heat and humidity can slightly reduce panel efficiency, but this is already factored into production estimates for our region. Modern panels are designed to perform well in these conditions, and the regular rainfall in East Texas helps keep them clean, maintaining their output.
What's the payback period for a solar-only system in Longview?
For a solar-only system costing about $8,050 after incentives, the payback period is just under 10 years. For a solar and battery system, the financial payback extends to about 20 years, though the non-financial benefits of backup power begin immediately.
