Solar panel installation is the process of mounting photovoltaic (PV) panels on a roof or ground frame and connecting them to a home’s electrical system so the house can generate its own electricity. A complete system turns sunlight into power, offsets what the home would otherwise buy from the utility, and feeds any surplus back to the grid. The reasons to install it changed sharply in 2026, because the federal tax credit that made the math easy for a decade expired at the end of 2025. Evolution Moving Company works with households across Dallas, Fort Worth, San Antonio, and Austin who buy and sell homes with solar already on the roof, so this guide explains both the why and the how in plain terms, using current 2026 cost and policy data.
Homeowners install solar to replace a rising, unpredictable utility bill with a fixed, owned asset. A solar system typically reduces a home’s grid electricity use by 70 to 90 percent, and the panels keep producing for decades after they are paid off. That is the core appeal, and it holds even now that the federal credit is gone.
The savings are real but vary by location. Across 25 years, owners commonly save somewhere between $37,000 and over $100,000 in avoided electricity costs, with the figure rising in states with high power rates. The catch is the payback period, the time it takes for savings to cover the system cost. Nationally that period now runs about 8 to 12 years. In Texas it tends to run longer, often around 13 years, because Texas electricity rates are relatively low, which means each kilowatt-hour you offset is worth less. Solar still pays off here, it simply takes more patience than in a high-rate state.
There is also a home-value effect. Studies consistently find that an owned solar system raises a home’s resale value, similar to other durable upgrades. If you are weighing solar against other improvements, our guide to 7 brilliant DIY home remodel ideas compares the return on more common projects.
Solar panel cost in 2026 is measured in dollars per watt of installed capacity. The national average runs roughly $2.50 to $3.50 per watt before any incentives, which puts a typical system somewhere between $20,000 and $30,000 installed. Texas sits at the low end of the cost range, near $2.20 to $2.35 per watt, thanks to strong sun and heavy installer competition.
Several factors move the final price: system size, roof type and pitch, the equipment you select, and local labor rates. Larger systems cost more in total but less per watt, because the fixed costs spread across more panels. Panels themselves are only a fraction of the price, with permits, labor, and other soft costs making up the rest.
The single biggest change for 2026 is that the federal residential solar tax credit no longer exists for new homeowner-owned systems. The Residential Clean Energy Credit, known in the tax code as Section 25D, gave homeowners 30 percent of their solar costs back as a credit against federal income tax. The One Big Beautiful Bill Act, signed in July 2025, terminated that credit for any system installed after December 31, 2025. The IRS has confirmed that a system must have been fully installed by that date to qualify, and no phase-down or partial credit applies in 2026.
Some paths to a federal incentive remain, but they are indirect. A separate commercial credit, Section 48E, can still be claimed by businesses, which means a homeowner can capture part of its value through a third-party-owned arrangement such as a lease or a power purchase agreement (PPA). A PPA is a contract where a company owns the panels on your roof and sells you the power, usually at a rate below the utility’s. State and local incentives also continue independently of federal law, and net metering still matters in many areas. Net metering is a billing policy that credits you for surplus electricity your panels send back to the grid.
Texas has no state income tax, so there is no state solar tax credit to claim, but the state does exempt the added home value from solar from property tax, and several utilities offer their own buyback or rebate programs. Because tax rules are specific to each household and each year, treat this section as background and confirm your own situation with a licensed tax professional before you sign anything.

Solar panel installation follows a defined sequence that usually spans a few weeks from contract to activation, even though the physical work on your roof takes only a day or two. The steps are consistent across most installers.
- Site assessment. An installer evaluates your roof’s age, angle, shading, and your past electricity use to size the system.
- System design and proposal. The installer designs the array, estimates production, and gives you a written quote with the cost per watt and projected savings.
- Permitting. The installer files the permits your city and utility require, which is often the longest wait in the timeline.
- Installation day. The crew mounts the racking, sets the panels, installs the inverter, and connects the system to your electrical panel.
- Inspection. A local official inspects the work to confirm it meets electrical and building code.
- Interconnection and permission to operate. The utility approves the connection and issues permission to operate (PTO), and only then can the system legally generate power for your home.
Once you have PTO, the system begins producing electricity and offsetting your bill from that day forward.
A solar panel system is built to generate electricity for 25 to 30 years. Panels lose a small amount of output each year, a process called degradation, but most are still producing around 85 to 90 percent of their original capacity after 25 years. That long life is what makes the multi-year payback acceptable, since the system keeps saving money long after it breaks even.
Maintenance is light. Rain handles most cleaning, though panels in dusty or pollen-heavy areas benefit from an occasional rinse. The inverter is the component most likely to need replacement during the system’s life, typically once after 10 to 15 years. Keep the panels free of heavy shade from growing trees, and the system largely runs itself.
Solar changes a home sale, and whether it helps or complicates the deal depends on one question: is the system owned or leased. An owned system, paid in cash or financed and fully yours, transfers with the house and generally adds value, because the buyer inherits free electricity. A leased system or a PPA is different. The contract has to be transferred to the buyer or bought out, and some buyers hesitate to take on payments they did not choose.
If you are buying a home with solar, ask for the system’s ownership status, its age, the production history, and any transferable warranty before you close. If you are selling, gather those same documents in advance so the panels read as an asset, not a question mark.
Choosing an installer is the decision that most affects whether solar pays off, because installation quality determines production and durability. Compare at least three written quotes on the same basis, the cost per watt, so you are comparing equal terms.
Look for an installer who holds NABCEP certification, the North American Board of Certified Energy Practitioners credential that signals trained, vetted professionals. Confirm the workmanship warranty and the separate equipment warranties on the panels and inverter, and ask for a production estimate in writing. A larger refresh of the home around a solar install can make sense too, and our comparison of bath vs shower options, costs, and tradeoffs is a useful companion if you are budgeting several projects at once.
