When solar isn't worth it
If you just ran an estimate with us and the numbers came back underwhelming, a small system, a long payback, savings that don't add up to much, this page is why.
Our estimate is built to tell you the truth, including when the truth is that solar isn't the right move for your home right now. A commissioned salesperson is paid to talk you past these reasons. We don't have any, so we'll just name them.
Here are the most common reasons an honest estimate comes back weak, and what, if anything, would change it.
Your roof gets too much shade, faces the wrong way, or has too little usable area. Solar needs sun. Heavy tree cover, a north-facing roof, or a small or cut-up roof plane can shrink the system we can fit to the point where it produces too little to matter. What would change it:trimming or removing trees can open up a roof. A north-facing roof or a genuinely small one usually can't be fixed, and that's an honest no.
Your roof is near the end of its life. Solar lasts 25 years or more. If your roof has only a few years left, the panels have to come off and go back on when you re-roof, at your cost. What would change it:replace the roof first, then go solar onto a roof that will outlast the system. We'll tell you to do it in that order.
Your electricity usage is low. A small bill means small savings, which means a long payback. If you don't use much power, there isn't much for solar to offset. What would change it: if your usage is about to climb (an electric vehicle, an addition, a heat pump, a growing household), the math can shift. Run it again when it does.
You're planning to move soon. Solar pays itself back over many years. The typical homeowner stays about 12 years. If you expect to be gone well before the system pays for itself, the savings may never reach you. What would change it: a longer time horizon. If you plan to stay, the years are on your side.
Your utility doesn't pay you back well for the power you send to the grid. Austin Energy credits the electricity you export at a wholesale-style value rather than your full retail rate, so a system sized to “cover” your usage doesn't save the way many people assume. What would change it:sizing the system to what you actually use during the day rather than overbuilding. And if you're on the Oncor grid and choose your own retail electric provider, the plan you pick can change how much your exported power is worth.
The federal tax credit no longer covers an owned system. For over a decade, a homeowner who bought solar could claim a 30% federal tax credit (Section 25D) on their return. That credit was terminated at the end of 2025. A system placed in service in 2026 or later doesn't qualify, so a customer-owned install today has no direct federal tax credit behind it. That matters most on a financed purchase, where the credit used to offset a large share of what you borrowed. Take it away and the payback stretches, especially once loan interest and any dealer fee are added in.
You may still see “30% tax credit” in solar ads. In 2026 that almost always points to the commercial credit (Section 48E), which is still in place, but it's captured by the third party who owns the panels under a lease or power-purchase agreement, not by you. Smaller state and utility incentives do still apply. Austin Energy, for one, offers a residential rebate. They just don't reach the scale the old federal credit did.
What would change it: a cash purchase on a strong roof can still pencil without leaning on a credit, since you skip the loan interest and the math rests on the system paying for itself through avoided utility costs. Whether cash, a loan, or a third-party-owned structure fits you depends on your situation, and the estimate accounts for it.
Why we tell you this
We'd rather lose the sale than sell you a system that doesn't pay you back. A customer who got a straight answer is worth more to us than one who got talked into the wrong call, and the whole company is built around handing you a real number instead of a pitch.
So if your estimate looked weak, take it at face value. And if your situation changes (you trim the trees, you replace the roof, your usage climbs, you decide to stay), run the numbers again. They might tell a different story.
