Ground Mount Solar Cost in Texas

What to expect when pricing a backyard solar installation in 2025. Real numbers, no surprises.

The Quick Answer

Ground mount solar in Texas typically costs $3.50 - $5.00 per watt before incentives. That's roughly 10-15% more than rooftop solar due to the additional racking and foundation work.

For a typical 8kW system: $28,000 - $40,000 before the 30% federal tax credit, or $19,600 - $28,000 after.

Why Ground Mount Costs More (And Why It's Worth It)

Ground mount systems require more materials and labor than rooftop. But that extra investment often pays for itself.

The Extra Costs

  • • Heavy-duty steel racking system
  • • Concrete or helical pile foundations
  • • Trenching for underground wiring
  • • Additional engineering requirements

The Payoff

  • • 10-25% better energy production (optimal angle)
  • • No roof damage or leak risk
  • • No $10K removal cost if roof needs work
  • • Easier maintenance and cleaning
  • • Longer system lifespan

After 30% credit:$24,500 - $35,000
15 kW

Produces 19,500-23,500 kWh/year

Before tax credit:$52,500 - $75,000
After 30% credit:$36,750 - $52,500

The 30% Federal Tax Credit

The federal Investment Tax Credit (ITC) lets you deduct 30% of your total solar installation cost from your federal taxes. This applies to ground mount systems just like rooftop.

  • • Available through 2032 at 30%
  • • Steps down to 26% in 2033, 22% in 2034
  • • Applies to equipment, labor, permits, and engineering
  • • Can be carried forward if you don't owe enough taxes

Note: This is a tax credit, not a rebate. Consult a tax professional for your specific situation.

Payback Period & ROI

Most Texas ground mount systems pay for themselves in 7-10 years, with 25+ year equipment warranties. Here's how the math works:

$150-200

Typical monthly savings

(8kW system, average usage)

7-10

Years to payback

After federal tax credit

$50K+

Lifetime savings

Over 25 year lifespan

What Affects Your Specific Cost

Soil Conditions

Rocky Hill Country soil may require helical piles instead of concrete, adding $0.10-0.20/W. Soft soil is easier and cheaper.

Distance from Electrical Panel

Longer trenching runs increase wiring costs. Typical residential is 50-100 feet; longer runs add $1-3 per foot.

System Size

Larger systems have lower per-watt costs due to fixed expenses being spread across more capacity.

Equipment Quality

Tier 1 panels and premium inverters cost more upfront but offer better warranties and longer lifespans.
