Cost + savings
How much do solar panels cost in 2026?
A typical 8-12 kW residential solar system in Texas costs $20,000 to $35,000 fully installed in 2026, before any incentives. That works out to roughly $2.50 to $3.50 per watt. Your specific number depends on system size, panel choice, whether you add a battery, roof complexity, and how many electrical upgrades the install requires.
What's actually in the price
| Line item | Typical share | What it covers |
|---|---|---|
| Panels | 20–25% | Tier-1 modules (Mission Solar, Q CELLS, etc.) |
| Inverter or microinverters | 10–15% | Either one string inverter or per-panel microinverters |
| Racking + flashing | 5–10% | Aluminum rails + watertight roof penetrations |
| Electrical work | 10–15% | Service-panel upgrades, wiring, conduit, breakers |
| Permits + interconnection | 3–5% | City permit, utility application, inspection |
| Install labor | 20–30% | Crew, foreman, design, project management |
| Monitoring + commissioning | 2–5% | Gateway hardware + first-day system test |
Three ways to pay
How you pay changes the lifetime cost, not the install price. The three options Kaizen offers:
- Cash — full system price up front. Highest lifetime savings, fastest payback (typically 6-9 years in Texas).
- $0-down loan — monthly payment usually less than your prior utility bill from day one. 12-25 year terms with rates from approved lenders.
- Lease / TPO — Kaizen's third-party-ownership partner owns the system; you pay a locked-in per-kWh rate well below your utility's. Zero maintenance, no maintenance contract needed.
Battery adds about $10k-$18k
A single Tesla Powerwall 3 (13.5 kWh) installed runs roughly $13,000-$15,000. An Enphase IQ Battery 5P (5 kWh module) is closer to $7,000-$9,000 per module. Whole-home backup typically requires two Powerwalls or three to four IQ modules.
Federal incentive status
The federal Residential Clean Energy Credit (Section 25D, formerly the ITC) is a separate question your CPA should answer based on your tax situation. Kaizen does not provide tax advice. We design and install the system; the tax conversation stays between you and your accountant.
Common questions
Frequently asked
- What is the average solar payback in Texas?
- For cash purchases at current Texas utility rates (12-15¢/kWh), payback is typically 6-9 years on a properly-sized system. After payback, every kWh produced is essentially free for the remaining 16-19 years of the warranty.
- Why does the same system cost more on some quotes than others?
- The biggest variables are panel tier, inverter architecture, dealer markup, and whether the price includes a battery. Always ask for a per-watt cost — that's the apples-to-apples comparison.
- Do I have to pay for the system before it produces?
- On cash, yes — typically a 20% deposit at contract signing and the balance at install. On loans and leases, your first payment doesn't start until the system is producing.
