Cost + savings
Are solar panels worth it in 2026?
6 min read
For most American homeowners with a sunny roof and a 5+ year stay, yes — owned solar pays back in 6-9 years and produces near-free electricity for the remaining 16-19 years of warranty. The honest answer requires three numbers: your monthly utility bill, your roof's solar potential, and your stay horizon. The rest is arithmetic.
There are also clear cases where solar isn't worth it. We'll walk through both.
The three numbers that decide it
- Your monthly utility bill — solar payback is fastest at $200+/month consumption. Below $80/month, the math gets tight.
- Your roof's solar potential — south, east, or west pitches with minimal shading. North-only or 60%+ shade is the only true non-starter.
- Your stay horizon — 5+ years to capture meaningful payback; 8+ years to net six-figure savings on a typical Texas system.
Worth it: typical Texas case
| Variable | Value | Why it matters |
|---|---|---|
| Pre-solar bill | $280/month average | High consumption = fast payback |
| System size | 10 kW (typical 4BR home) | Sized to offset 90-100% of usage |
| Cash install cost | $28,000 | Mid-range tier-1 panels |
| Year-1 utility savings | $3,360 | $280/month × 12 |
| Payback period | 8.3 years | Cash math |
| 25-year savings | $84,000+ | After payback, nearly free electricity |
Not worth it: cases where the math doesn't work
- Pre-solar bill below $80/month — too little usage to amortize the install.
- Stay horizon under 3 years — payback math is tight unless you'll capture the resale premium.
- Roof has 60%+ shade across the south, east, and west pitches.
- Roof needs replacement within 5 years — re-roof first, then install.
- Renters — you can't capture the asset value in a system you don't own.
What changes the answer
- Adding a battery — increases install cost but unlocks backup, peak-rate avoidance, and energy independence. Math improves in markets without full retail net metering (most of Texas).
- Buying an EV or heat pump — your load profile grows, making solar payback faster.
- Utility rate hikes — every 10% rate increase shortens your payback by ~1 year. Texas rates rose 30% between 2020 and 2025.
- Time-of-use rate plans — solar without a battery captures less value when peak rates are highest after sundown.
Common questions
Frequently asked
- What's the average payback period for solar in Texas?
- 6-9 years for cash purchases at current Texas utility rates (12-15¢/kWh). Loans extend the payback because of interest, but your monthly payment is usually lower than your prior utility bill.
- Are solar panels worth it if I plan to move?
- If you're moving in less than 3 years, payback is tight. If you're moving in 3-7 years, you can typically capture much of the install cost in the resale premium (4-6% per Zillow research). 7+ years and the math is straightforwardly positive.
- Is leased solar worth it?
- Different math. Leased systems lower your monthly bill from day one with no out-of-pocket — but you don't own the asset and capture less lifetime savings than cash. Worth it for homeowners who want lower bills with zero risk and zero hardware ownership.
