Solar Energy: Pros and Cons for Texas Homes

Solar energy is gaining ground across Texas, and for good reason—our plentiful sunshine makes it ideal for powering homes in Dallas, Houston, the Hill Country and beyond. As solar panels pop up on rooftops, many homeowners start to wonder: is solar energy worth it?

Solar energy can help manage electricity costs and reduce environmental impact. But it’s not the right fit for everyone. There are practical tradeoffs and upfront costs to consider before going solar.

How Solar Energy Works for Homes

Solar power for homes is straightforward. Panels on your roof use photovoltaic (PV) cells to turn sunlight into direct current (DC) electricity. An inverter then changes that DC electricity into alternating current (AC)—the kind your lights, appliances and gadgets need.

You can use solar energy at home in three main ways:

1. Use it right away: Power your home as sunlight hits your panels.
2. Store it: Charge a battery for use at night or if the power goes out.
3. Share it with the grid: Send extra electricity back to the grid, which can earn you bill credits depending on your plan.

The Good: Benefits of Solar Energy

There are strong reasons to consider solar for your home.

1. Renewable and Low-Emission

Solar power comes from an abundant source and doesn’t require burning fossil fuels. Using solar can help reduce greenhouse gas emissions and other environmental impacts. 

2. Can Lower Electricity Bills

A solar system can cut down on how much electricity you need from the grid. Even small solar upgrades—like outdoor solar lighting—help lower home energy use over time.

3. Incentives Can Cut Costs

Federal and state incentives can help offset the cost of solar panels. Incentive programs vary by area, but the federal tax credit alone can be a big help. For a full list of current solar incentives, visit Go Solar Texas.

4. May Boost Home Value

Solar energy systems are seen as modern and efficient. According to Zillow, homes with panels sell for 4.1% more than similar homes without them.

5. Low Maintenance

Solar panels have no moving parts and are built to last decades. With periodic cleaning and inspection, they deliver years of reliable power.

6. Works in Many Climates

Panels generate power even on cloudy days, and cooler weather doesn’t reduce performance. In some cases, reflected sunlight can actually help.

7. Storage Adds Flexibility

Battery storage systems let you save extra solar energy for use during evenings or peak times—and can keep some essentials powered during outages.

8. Can Share Back to the Grid

If your panels make more electricity than you need, you can send the surplus to the grid. With a TXU Energy solar buyback plan, you can earn bill credits for that extra power—visit txu.com/buyback for details.

9. More Accessible Than Ever

Lower equipment prices and new financing options make solar systems more attainable. Technology has come a long way in just the last decade.

The Bad: The Major Challenges of Solar Energy

While there’s a lot to love, solar comes with some challenges.

1. High Upfront Costs

Solar panels are a significant investment, with costs for permits and installation in addition to the panels. Leasing or financing can reduce upfront expenses, but savings add up over time—usually for long-term homeowners with sunny roofs. Incentives and buyback programs may help make solar more appealing.

2. Batteries Add Cost and Complexity

Batteries bring independence, but they’re pricey and need replacing over time. Adding one can almost double your total system cost.

3. Not All Roofs Are Right

Solar works best on south-facing roofs with little shade. If you have lots of trees or an older roof, it can increase costs or limit performance.

4. Only Works When the Sun Shines

Panels don’t work at night and produce less when it’s cloudy or rainy. That means you’ll still need grid power, especially without large battery banks.

5. Long Term Maintenance

Outdoor systems are exposed to weather and the environment, so regular checkups go a long way. While panels themselves last for decades, parts like inverters or batteries may need replacing down the road. Planning for periodic professional inspections offers peace of mind and helps protect your long-term investment.

Solar Alternatives: Cleaner Energy Without Panels

You don’t need panels to support green energy. TXU Energy offers renewable electricity plans that let you power your home with solar and wind—no installation required

Is Solar Right for Your Home?

Your home, budget and long-term plans all play a part in the right energy choice.

Solar makes sense if your roof gets lots of sun, you plan to stay in your home and you’re looking for long-term savings. If your electricity bills are high and you qualify for tax incentives, going solar often makes more sense.

If rooftop solar isn’t practical, a renewable electricity plan from TXU Energy is an easy and flexible way to support cleaner energy.
