Who We Are

Operating Unit of Advisory Engineering & Analytics, PE

We are a registered Texas Professional Engineering Firm (Firm #14614, P.E. 66872) based in De Kalb, Texas. GroundArrayUSA opened its doors in response to local requests after we engineered and constructed our own customized solar solution to power our farm in Bowie County.

With a background of over 35 years designing and constructing large-scale national communications and utility networks, we bring unmatched rigour to residential and commercial energy systems. We help homeowners, farmers, ranchers, and business owners secure backup power, eliminate escalating utility bills, and establish a sustainable energy future.

Licensed Professionals: All configurations are approved by a Texas Professional Engineer (PE).
Local Presence: Proudly based in De Kalb, TX, serving our rural neighbors.
Honest Guidance: We pick up the phone, carry spare parts locally, and prioritize sizing systems correctly over selling upsells.
Why Ground Arrays?

The Ground-Mount Advantage

Unless a home is structurally designed and built to support the weight and angle of solar panels, we prefer not to load your roof. If you have land, ground-mounting is superior in every way.

Protect Your Roof

Zero roof penetrations. Avoid structural stress, roof leaks, and the massive cost of removing panels when you need to re-shingle your home.

Optimal Siting & Angle

Roofs force a fixed angle and direction. Ground arrays can be sited at the perfect compass heading and pitch to maximize solar gain year-round.

Easy Maintenance

Keep your panels clear of dust, leaves, and snow without ever climbing a ladder. Siting batteries, inverters, and well-controls at chest level keeps hardware safe and easily accessible.

How We Build It

Our 6-Step Engineered Delivery Process

A typical ground array takes approximately 6 weeks from a signed proposal to final power-on and client training.

1
Week 1 (Initial)

Site Visit & Load Analysis

We visit your homestead to inspect the topography, measure sun shading, review your past 12-month utility bills, and outline critical loads (like well pumps and HVAC).

2
Week 1 (Design)

Custom Proposal & Modeling

Our engineering team designs the exact structural grounding, electrical paths, and selects components. You receive a fully itemized proposal with clear budget tiers.

3
Week 2

CPA & Bank Review

Review the design details and structural calculations with your local bank for financing options and your CPA to finalize 2026 tax rebate carryforwards.

4
Weeks 3 - 4

Order Parts & Siting Prep

We order the components through Signature Solar. While shipping occurs, we prepare the ground array location, install concrete footings, and construct the steel frame.

5
Weeks 5 - 6

Build & Connection

Our crew mounts the solar panels and conduits. A licensed local electrician completes the backup switch, battery connections, well-controls, and utility tie-ins.

6
Week 6 (Completion)

Test, Calibrate & Train

We commission the system, test safety cut-offs, load charge parameters, and spend hours training you exactly how to operate, monitor, and configure the backup features.

2026 Policy Landscape

Tax Rebates, Credits, and Incentives for Residential Solar

The incentives for residential solar installations have transitioned in 2026 after the passage of the One Big Beautiful Bill Act (OBBBA) on July 4, 2025.

1. Federal Credit (Section 25D) Expiry

The standard federal residential solar tax credit has expired for direct consumer purchases of solar systems placed in service on or after January 1, 2026. However, any carryover amounts from systems installed prior to December 31, 2025, are likely applicable to offset your tax liability.

2. Third-Party Leases & PPAs

While the personal tax credit (Section 25D) has ended, the commercial solar credit (Section 48E) remains active. Solar leasing or Power Purchase Agreements (PPAs) allow developers to utilize the tax credit and pass savings directly to consumers through reduced rental rates.

Important Legal & Financial Disclaimer

Please note: As with everything legal and financial, we are not your CPA or attorney. We do not provide tax or legal advice. Please consult with a qualified CPA or attorney to ask how the tax rules, credits, and laws apply to your specific financial situation.

Incentives Summary Report

Compliance Date: July 19, 2026

Section 25D Credit (Purchases) Expired (12/31/2025)
Section 48E Commercial Credit (Leases) Active (Up to 30%)
TX Property Tax Valuation Add-on 100% Exempt
Virtual Power Plant (VPP) Payouts Utility Dependent

Consult Your Tax Professional: Siting ground arrays on active agricultural land or farms can sometimes open commercial classification options. Consult your tax preparer.

Got Questions?

Frequently Asked Questions

Here are common questions we receive regarding ground arrays, battery storage, and solar installations.

Our focus is strictly on constructing ground array systems. Unless a home was specifically engineered from the ground up to support solar panels, we prefer not to load your structure. Ground-mounting on your land is safer, maximizes efficiency, and avoids structural stress or leak hazards.

  • Basic System: Requires about 25 ft x 15 ft of land for 18–20 panels; the electronics box requires 8 ft of wall space.
  • Hybrid System: Requires about 50 ft x 15 ft of land for 36 panels; the electronics cabinet requires 12 ft of wall space.
  • Large System: Scalable based on loads, typically combining multiple rows of arrays.

We are a division of Advisory Engineering & Analytics, LLC (a registered Texas Engineering Firm). We opened our doors after completing our own complex ground array setup on our Bowie County homestead to ensure our local community had access to engineered, reliable solar solutions designed by professional engineers.

EG4 power electronics, lithium batteries, and balancing equipment are field-proven and extremely reliable. Best of all, Signature Solar is based nearby in Sulphur Springs, Texas. If a part needs to be replaced under warranty or serviced, we can secure it within hours—rather than waiting weeks for overseas shipping, which is critical during storm and harvest seasons.
