Why Rooftop Solar Is More Than Just an Energy Decision
Roof top solar systems are a fast-growing energy source for Dallas-Fort Worth homeowners. These photovoltaic (PV) systems use roof-mounted panels to convert sunlight into electricity, offering significant financial and environmental benefits. Residential systems typically range from 5-20 kW, with options for grid-tied, off-grid, or hybrid battery backup configurations. Homeowners can save an average of $50,000 over 25 years, and homes with solar sell for 4.1% more.
The growth is undeniable: U.S. residential solar capacity jumped 27-fold between 2010 and 2020, while installation costs have been cut in half. Choosing solar is a move toward energy independence, protection from rising utility rates, and a smaller environmental footprint. However, it’s a major property investment that demands careful planning.
I’m Dustin Eatman, owner of James Kate Roofing & Solar. I’ve dedicated my career to helping DFW homeowners steer the crucial link between quality roofing and roof top solar systems. A solar installation is only as reliable as the roof it sits on. This guide will provide the essential information you need to make a confident decision.
Understanding Your Roof Top Solar Systems
At its core, a roof top solar system uses photovoltaic (PV) technology to convert sunlight directly into electricity for your home or business. This happens through the photovoltaic effect: when sunlight strikes solar cells made of semiconductor materials, it creates an electric current. Individual cells are grouped into modules (panels), and panels are combined into arrays to generate sufficient power.
PV systems are modular and scalable. Residential roof top solar systems typically have a capacity of 5–20 kilowatts (kW), enough to greatly reduce or eliminate an electricity bill. Commercial systems are larger, ranging from 100 kW to over 1 megawatt (MW).
To learn more about the science, the Department of Energy offers a great resource on Solar Photovoltaic Technology Basics.
Types of Solar Systems
When considering a roof top solar system, you’ll encounter three main types:
-
Grid-Tied Systems: The most common type in the DFW area. The system is connected to the local utility grid. Excess power you generate is sent to the grid for credit, and you draw power from the grid when your panels aren’t producing enough (like at night). This setup allows you to offset your electricity costs.
-
Off-Grid Systems: These are completely independent of the utility grid and are best for remote locations. They require a battery bank to store energy for use at night or on cloudy days. Off-grid systems offer total energy independence but are more complex and expensive.
-
Hybrid Systems with Battery Storage: A hybrid system combines the benefits of grid-tied and off-grid setups. It’s connected to the grid but also includes a battery. This allows you to store excess solar energy for later use, providing backup power during outages and increasing your energy resilience—a key concern for many Texans.
Key Components of Roof Top Solar Systems
A complete roof top solar system is a set of interconnected components working together.
-
Photovoltaic (PV) Panels: These modules capture sunlight and convert it into direct current (DC) electricity. Most panels today use silicon-based solar cells.
-
Inverters: This essential device converts the DC electricity from your panels into the alternating current (AC) electricity used by your home and the grid. The two main types are:
- String Inverters: A single inverter connects a “string” of panels. They are cost-effective but can be less efficient if some panels are shaded.
- Microinverters: Each panel gets its own small inverter. This maximizes output from each panel independently, making them ideal for roofs with complex layouts or partial shading.
-
Racking and Mounting Hardware: This is the framework that securely attaches the panels to your roof. A properly installed racking system is crucial to withstand Texas weather and protect your roof’s integrity with watertight seals.
-
Solar Battery (Optional): A battery, like the Tesla Powerwall, stores excess solar energy. This stored power can be used at night, during peak-rate hours, or as a backup during a power outage, significantly boosting your energy independence.
-
Monitoring System: This system provides real-time data on your energy production and consumption, usually through a home display or a smartphone app. It allows you to track savings and ensure your system is performing correctly.
The Financial Case for Solar
The decision to install a roof top solar system is a powerful financial investment, not just an environmental one. The economics have shifted dramatically, making it a smart choice for DFW homeowners.
Key financial benefits include:
- Cost Reduction: The cost of residential solar has fallen by half in recent years, making it more accessible than ever.
- Increased Home Value: Homes with solar panels sell for an average of 4.1% more than comparable homes without them.
- Long-Term Savings: Homeowners can save an average of $50,000 over 25 years. A cash purchase could yield savings of $60,000 over 20 years, while even a loan-financed system can save $20,000 in the same period.
- Fast Energy Payback: A PV system typically generates more clean energy than was used to manufacture it within just 2 years.
For a detailed look at financing options, the Homeowner’s Guide to Solar Financing is an excellent resource.
Opening up Incentives and Tax Credits
Incentives and tax credits are major drivers of solar’s financial appeal, reducing upfront costs and speeding up your return on investment.
The most significant is the Federal Solar Investment Tax Credit (ITC), which allows you to deduct a percentage of your system’s cost from your federal taxes. This credit directly reduces your tax liability, making solar much more affordable. Its availability and percentage can change, so it’s important to check its current status.
Local utilities in Texas may also offer rebates or other incentives. The Database of State Incentives for Renewables & Efficiency is a comprehensive resource for finding programs in the DFW area.
Additionally, your roof top solar system generates Renewable Energy Credits (RECs), which represent the environmental attributes of your clean energy. These can sometimes be sold for an additional revenue stream. Learn more at the EPA’s page on Renewable Energy Certificates (RECs).
Buying vs. Leasing Your Roof Top Solar Systems
You can either purchase your system (with cash or a loan) or use a third-party ownership model like a lease or Power Purchase Agreement (PPA).
| Feature | Buying (Cash Purchase or Loan) | Leasing / Power Purchase Agreement (PPA) |
|---|---|---|
| Ownership | You own the system | Third-party company owns the system |
| Upfront Cost | Higher (cash) or low (loan, often less than energy bill) | Low to none |
| Financial Benefits | Eligible for Federal ITC, RECs, and other incentives. Maximize long-term savings. | No eligibility for Federal ITC or RECs (owner gets them). Lower electricity bill. |
| Maintenance | You are responsible | Company is responsible |
| Home Value | Increases home value (sells for 4.1% more) | Can complicate home sale (new buyer assumes contract) |
| Savings Potential | Highest total savings over system lifespan (e.g., $60,000 over 20 years with cash) | Significant savings, but less than buying (e.g., $25,000 over 20 years) |
| Flexibility | More control over system upgrades and modifications | Limited control, bound by contract terms |
-
Buying (Cash or Loan): Purchasing offers the greatest long-term financial return. You own the system and are eligible for all tax credits and incentives. Solar loans make this accessible with little to no upfront cost, and monthly payments are often less than your old utility bill.
-
Leasing or PPA: With a lease or PPA, a third party owns and maintains the system on your roof for little to no upfront cost. You pay a fixed rate for the power, which is typically lower than the utility’s rate. While you save money monthly, you are not eligible for the tax credits, and the total savings are less than with ownership.
Is Your Home a Good Candidate for Solar?
Before choosing panels and inverters, the first step is to assess if your home is a good candidate for a roof top solar system. This involves evaluating your roof, energy usage, and sun exposure. As a DFW company specializing in both roofing and solar, James Kate Roofing & Solar understands that a solar installation is only as good as the roof it’s on.
First, you must own your home. The next critical factor is your roof’s condition. If it’s old or needs repairs, it’s best to replace it before installing solar panels to avoid the future cost and hassle of removing and reinstalling the array. Our 25-year workmanship warranty provides peace of mind for both your roof and solar integration.
Your system size should be based on your electricity consumption (found on your utility bill) to maximize savings. It’s also important to check local HOA rules. Finally, the amount of direct sunlight your roof receives (insolation) is crucial, as shadows from trees or buildings can reduce efficiency.
Key Roof Assessment Factors
A professional roof assessment is essential. Here are the key factors we evaluate:
-
Roof Age and Structural Integrity: Solar panels last 25-30+ years. Your roof should be new enough to last just as long. The structure must also be strong enough to support the added weight of the panels and racking.
-
Roof Material: Different materials require different installation techniques. Asphalt shingles are common and straightforward. Metal roofs are often ideal, sometimes allowing for mounting without roof penetration. Tile roofs require specialized hardware to prevent breakage and leaks.
-
Roof Orientation and Pitch: In the DFW area, a south-facing roof is optimal for energy production. However, modern high-efficiency panels still perform very well on east or west-facing roofs.
-
Shading: Even partial shading can significantly reduce a system’s output. We assess shading from trees and structures and can recommend solutions like tree trimming or using microinverters to mitigate the impact.

The Broader Impact of Your Solar Investment
Installing a roof top solar system extends far beyond your personal financial savings. It’s a decision with ripple effects, contributing to a more resilient grid, fostering economic growth, and significantly benefiting the environment for our communities across North Texas.
How Net Metering Works
Net metering is a crucial policy that makes grid-tied roof top solar systems financially viable and attractive. Here’s how it works:
When your solar panels generate more electricity than your home or business consumes at any given moment (for example, on a sunny afternoon when you’re at work), that excess energy doesn’t go to waste. Instead, it is automatically exported back to the utility grid. Your electric meter, often a smart meter, effectively spins backward or records the amount of electricity you send to the grid.
In return for contributing clean energy to the grid, your utility company provides you with credits on your electricity bill. These credits can then be used to offset the cost of electricity you draw from the grid at other times, such as at night or on cloudy days when your panels aren’t producing enough. Essentially, net metering allows you to use the grid as a giant battery, storing your excess solar production for later use.
The specifics of net metering policies, including the rate at which you are credited for your exported power, can vary by utility and local regulations. It’s important to understand your local utility’s net metering policy to fully grasp the financial benefits of your roof top solar system. We can help you understand these local policies and how they apply to your specific situation in the DFW area.
Environmental and Community Benefits
Beyond personal savings and energy independence, embracing roof top solar systems delivers substantial benefits to the environment and our broader community:
-
