Does Your Situation Sound Like This?

Texas law limits how much an HOA can restrict solar. Deed restrictions on setbacks or street-facing visibility may still apply — a county (and sometimes city) permit is still required either way.

Most of Bastrop and Fayette County has no HOA at all outside city limits. A county permit is still required regardless.

Mostly served by Bluebonnet Electric Cooperative. See your city's location page for the specific utility that covers your address.

Split between municipal utilities and Fayette Electric Cooperative. Depends on the specific city — see your city's location page.

Reasonable — timelines vary by utility. We give you a real estimate specific to your address rather than a single sitewide number.

Worth knowing what's involved first. Permit review, utility interconnection review, and Permission to Operate are three separate steps most homeowners underestimate.

Two Separate Processes

A Permit and an Interconnection Agreement Are Not the Same Thing

The Permit Confirms Code Compliance

The permit — typically a county permit, and sometimes a city one depending on your exact address — confirms the installation itself meets electrical and building code. Texas's SB1202 also created a standardized third-party review process some jurisdictions use for solar permit review specifically, separate from a general building permit.

The Interconnection Agreement Is a Separate Process With Your Utility

This confirms your system can safely connect to the grid, and it isn't complete until the utility issues Permission to Operate (PTO) — the actual green light to turn your system on and start generating.

Which Utility Covers Your Property Is the One Genuinely Local Fact Here

Bastrop County properties are mostly served by Bluebonnet Electric Cooperative; Fayette County splits between municipal utilities and Fayette Electric Cooperative depending on the city — and each utility runs its own interconnection review timeline and requirements. Rather than repeat utility-specific detail here, that's covered on each city's own location page, since it's a fact that changes by address, not by which solar service you're getting.

Skipping Ahead Has Real Consequences

A system installed but not yet through PTO isn't authorized to export power to the grid, and running it prematurely creates a real safety issue — it can backfeed power into lines utility crews may believe are de-energized. We don't turn a system on until PTO is actually issued.

Costs & Incentives

What This Process Actually Costs

Permit & Interconnection Fees

Fees vary by county, city, and utility, and are handled as part of your project rather than quoted as a flat sitewide number.

Federal Tax Credit

The federal Residential Clean Energy Credit ended for systems installed on or after January 1, 2026 (One Big Beautiful Bill Act, per IRS FS-2025-05). Older marketing referencing a 30% federal credit is outdated.

Texas Property Tax Exemption

Still active. Texas Tax Code §11.27 exempts the added value of a solar energy device from your home's appraised value — filed via Form 50-123 with your county appraisal district (Bastrop CAD or Fayette CAD) after installation, once PTO is issued.

Top Questions, Ranked

Permitting & Interconnection FAQ

1. Do I actually need a permit to install solar in Texas?
Yes — nearly every residential solar installation requires at least a county permit, and sometimes a city permit as well depending on your specific address. This is standard practice statewide, not a Bastrop- or Fayette-specific requirement.
2. What's the difference between a permit and a utility interconnection agreement?
The permit confirms the installation meets electrical and building code and is issued by your county or city. The interconnection agreement is a separate process with your utility confirming the system can safely connect to the grid, and it's the interconnection process — not the permit — that ends with Permission to Operate.
3. Which utility serves my property, and does that change the process?
Yes, it changes the interconnection timeline and requirements specifically. Bastrop County is mostly served by Bluebonnet Electric Cooperative; Fayette County splits between municipal utilities and Fayette Electric Cooperative depending on the city. See your city's location page for the specific utility that covers your address.
4. How long does the whole permitting-and-interconnection process actually take?
It varies by county, city, and utility — permit review and utility interconnection review run on their own separate timelines and don't necessarily happen at the same pace. We give you a real estimate specific to your address and utility rather than a single sitewide number.
5. What is Permission to Operate (PTO), and why does it matter?
PTO is your utility's formal authorization to energize your system and begin exporting power to the grid. It comes after the interconnection agreement, inspection, and meter installation — and it's the actual point at which your system is authorized to legally turn on, not the moment installation finishes.
6. Who handles this paperwork — me or the installer?
We handle both the permit application and the utility interconnection paperwork as part of the installation process, including confirming which specific utility and permitting authority apply to your address.
7. Can an HOA or the county actually block my solar installation?
Texas law limits how much an HOA can restrict solar installations, though deed restrictions on setbacks or street-facing visibility may still apply depending on your subdivision. Outside city limits, most of Bastrop and Fayette County has no HOA at all. A county permit — and sometimes a city one — is still required regardless of HOA status.
8. Does a bigger or unusual system require a different process?
Sometimes — a larger system, a ground-mount array with its own foundation, or one that includes battery storage can involve additional review depending on your county and utility. This is confirmed for your specific project during the design and permitting process rather than assumed upfront.
9. What happens if I skip a step or turn my system on before approval?
The system isn't authorized to export power to the grid until PTO is issued, and doing so anyway creates a real safety risk to utility crews who may not expect the line to be energized. We don't activate a system before PTO is confirmed, for exactly this reason.
10. What documentation should I keep for insurance or a future home sale?
Your permit approval, interconnection agreement, and PTO confirmation are worth keeping on file — they document that the system was installed and connected through the proper process, which can matter for insurance purposes or when the property is eventually sold.
