If you want a roof that makes electricity, you have two very different paths: solar shingles, where the roof itself generates power, or traditional solar panels mounted on top of a regular roof. They look different, cost very different amounts, and suit different situations. Here is how they compare, and an important 2026 change to the federal tax credit you should know before you spend.
The two approaches
The difference is integration:
- Solar shingles, sometimes called solar roofing, are the roof and the solar system in one. Products like the Tesla Solar Roof and GAF Timberline Solar replace your roof and generate power at the same time.
- Solar panels are rigid modules bolted onto an existing roof with racking. Your roof stays a normal roof, and the panels sit on top.
What they cost
This is the biggest practical difference. Panels are far cheaper per unit of power:
- Traditional panels: roughly 15,000 to 25,000 dollars before any incentives, at about 2.50 to 3.50 dollars per watt.
- GAF solar shingles: roughly 33,000 to 42,000 dollars for a typical system on an average home.
- Tesla Solar Roof: often 50,000 to well over 100,000 dollars, since it is a premium full roof plus solar.
The key insight is that solar shingles only start to make financial sense when you need a new roof anyway. If you are replacing the roof and adding solar, a solar roof does both jobs at once. If your roof is fine, panels are the far better value.
Efficiency and looks
Panels are more efficient, usually converting 20 to 24 percent of sunlight, and they produce more power per dollar. Solar shingles are a bit less efficient, especially the glass-tile type, though the better shingle products come close to panels. Where shingles win is looks: they lie flush and blend into the roof, while panels sit up on racks. It is a trade of value and output, which panels win, against aesthetics and integration, which shingles win.
When each makes sense
- Choose solar shingles when you need a new roof anyway, want solar, and care about a seamless look.
- Choose panels when you have a good existing roof and want the best value and fastest payback.
The 30 percent federal solar credit ended after 2025
This is a big change. For years, homeowners who bought a solar system could claim a 30 percent federal tax credit, and it was scheduled to run through 2032. A 2025 law ended it early. A system you buy and install in 2026 or later no longer qualifies for that homeowner credit. A solar lease or power purchase agreement may still capture a credit through the installer, and some state, local, and utility incentives remain. This changed recently and is easy to get wrong, so verify the current rules and talk to a tax professional.
You can check the current federal rules on the IRS home energy credits page. We cover the roofing side of the change, and the fact that a plain new roof was never eligible anyway, in is a new roof tax deductible.
Lifespan
Both approaches carry warranties around 25 to 30 years. Remember that solar shingles are also your roof, so they carry both a power warranty and a roofing warranty, and the leading products are rated for high wind and impact, which matters in Texas and Florida.
“Panels are the better value on a good roof. Solar shingles make sense when you need a new roof anyway and want the clean, integrated look.”
The bottom line
For most homeowners with a sound roof, panels deliver more power for less money. If your roof is due for replacement and you want solar with a seamless appearance, solar shingles do both at once. Either way, the roof under it all has to be right, which starts with choosing the material, as we cover in types of roof shingles and the best roofing material for hot climates.
With Hommy you can post your job once and get quotes from vetted local roofers, each with real ratings from other homeowners, so the roof under your solar is one you can trust.
