Palmetto Reviews
Palmetto is an excellent solar power source. I have had no issues with Palmetto. I am a Sr IT Professional and utilize a lot of power. It is essential that you do a site survey for an annual average to get enough panels.

Overall great experience with Palmetto right from 1st contact till the panels are activated. I was informed on each and every step in advance, pricing is great, and the install crew was amazing. During inspection one small issue was observed and the crew came and fixed it asap without need of further follow ups.

I went through several quotes for solar panels before landing on Palmetto. Their quote was below other vendors, but it wasn’t a decision based on price. I chose them because they explained the product and the installation process very well. I was then set up with an app for tracking the installation process. I’m so happy I chose a company that cares about customer service!

Katy Electricity Prices
Curious why your Katy, TX energy bills keep climbing? Understanding local electricity costs is the first step toward smarter energy decisions.
Electricity isn’t getting cheaper. In Texas, average prices rose about 23%—from 12.1 cents per kWh in 2021 to 14.9 cents in 2024—steadily increasing what Katy homeowners pay each year.
Solar offers a way to take control. By generating your own power under Katy’s abundant sunshine, you can rely less on the grid and reduce your exposure to rising utility rates.
Over the long term, solar can bring more predictable energy costs. While utility prices tend to climb, a home solar system helps Katy families plan ahead with greater confidence and stability.

Katy Area Utility Providers
In Katy, TX, most homeowners get their power from Entergy. In 2023 (the latest data available), Entergy’s rate was about 13.2¢ per kWh—below both the state average of 14.5¢ and the national average of 16.0¢.
Why is Katy’s rate lower? Texas runs its own deregulated grid, and abundant natural gas and wind resources help keep costs down. This gives many Katy homeowners more affordable electricity than the national average in 2023.
Even with below-average rates, electricity prices can shift year to year. Solar panels let you generate your own power and gain more predictable energy costs, helping you rely less on changing utility rates over time.

Texas Solar Incentives
Several state and local programs can help offset the cost of solar panel installation in Katy, TX. Explore the available solar incentives in Texas below.
Texas homeowners benefit from a 100% property tax exemption on added home value and a sales tax exemption on solar equipment. Together, these lower both your upfront and long-term costs.
Local utility rebates, battery storage programs, and solar buyback plans add further savings. While the federal tax credit is no longer available, Texas incentives still make solar worthwhile. Leasing through LightReach also simplifies things—Palmetto handles the commercial ITC and passes savings along through lower monthly payments.
| Incentive | Type | Description | Source |
|---|---|---|---|
| Texas Property Tax Exemption for Solar Energy Systems | Property Tax Exemption | Texas homeowners receive a 100% property tax exemption on the added home value from a solar energy system installation, saving hundreds of dollars per year. | Learn More |
| Texas Sales Tax Exemption for Solar Equipment | Sales Tax Exemption | Solar energy equipment purchased in Texas is exempt from the state sales tax, reducing the upfront cost of installation. | Learn More |
| Texas Solar Buyback & Net Billing Programs | Net Metering | Texas does not mandate statewide net metering, but solar homeowners in deregulated areas can choose a Retail Electric Provider (REP) offering a solar buyback plan to receive credits for excess energy exported to the grid. | Learn More |
| Tesla Virtual Power Plant (VPP) Program | Rebate | Powerwall owners in select Oncor and CenterPoint service territories can earn a $10/month bill credit by enrolling in Tesla Electric’s Virtual Power Plant program. |
To claim the exemption, you must file Form 50-123 (Exemption Application for Solar or Wind-Powered Energy Devices) with your county appraisal district by April 30 of the year following installation. You do not need to re-file annually — the exemption remains in effect as long as the solar system is operational. Battery storage systems installed as part of a solar energy system and used to store solar-generated electricity generally qualify under the same exemption.
