The ZIPs around Fairview hold about 7,000 single-family lots of an acre or more — more than any other town in this part of Collin County.
Fairview is also one of the few places that publishes what its solar permit costs, which tells you something about how the Town handles them.
Your electric bill answers the first question here: who you buy from.
The Town lists three electric companies, and which one you are on decides whether your exported power is worth the retail rate or a fraction of it.
Nothing else on this page moves the arithmetic that far.
On GCEC lines you cannot shop for a provider, and in exchange you get kilowatt-hour netting at the full retail rate.
Every unit you send back takes a unit off your bill whether you used it or not, and unused units are banked for the following month.
Going solar moves you onto the distributed generation rate: a $40 monthly base charge where the ordinary residential rate carries $25, plus a one-time $40 application fee billed after the net meter is set.
The co-op states plainly that a $40 minimum bill stands even in a month you over-generate.
With retail netting the array can be sized to the land rather than to your own consumption, because the extra production keeps its full value instead of dropping to an export rate.
CoServ buys all of it and sells all of it back.
Exported energy earns CoServ's avoided wholesale cost — 8.5 cents a kilowatt hour in September 2026 — against a retail rate around twelve.
The credit shows up in dollars, and what you do not use rolls forward.
A $25 monthly minimum, made up of a $10 customer charge and a $15 distributed generation charge, and the credit is allowed to offset it.
On CoServ the array wants sizing to your own daytime use, because a unit that leaves the property is worth roughly two thirds of one you keep.
Oncor owns the wires and delivers the power; it does not buy any of it back — your retail provider does, on whatever terms that plan carries.
You can change providers when the contract ends, so it is the one arrangement here that is not fixed for the life of the array.
Every North Texas provider's terms are on one page: what each utility pays for exported solar
Fairview publishes the number: a residential solar PV permit is $175 on the Town's fee schedule.
The packet wants contractor registration, a plot plan, the electrical plan, attachment and elevation details, wiring calculations, equipment specifications and a structural letter.
The Town also runs a remote virtual inspection programme for solar, where photographs and video shot to a published specification stand in for a visit.
Its picture list is written for rooftop arrays — roof planes, rafters, roof jack flashing — so we agree with the department which items a ground mount answers before we shoot it.
Outside the Town limits, Texas counties have no general authority to require a building permit for ordinary single-family construction, and Collin County publishes none that reaches a residential array.
Septic setbacks, floodplain rules and the utility's interconnection approval apply either way.
We pull whichever applies, and where the Town will take a virtual inspection we shoot it to their spec rather than waiting on a visit.
Fairview is 92 percent dark clay topsoil, and the rock is on the west side.
A third of the points west of town reach bedrock inside three feet; north, east and south it is about one in five.
Those numbers come from 111 points of the USDA soil survey on land within six miles of the Town.
Houston Black clay covers close to half of them.
Another sixth is Austin silty clay, a shallower soil with rock at about thirty inches.
None came back sandy.
Blackland clay swells when it is wet and shrinks when it is not.
The movement is seasonal and it is uneven, which is what rotates a shallow foundation a few degrees off where it was set.
So the foundation reaches past the zone that moves, or into the rock where it is shallow.
On the acre-plus lots around here there is usually more than one workable spot, and the soil is part of choosing between them.
A south-facing array at the thirty degree tilt we build makes about 1,530 kWh a year for every kW installed at Fairview's latitude.
Ten kW installed is roughly 15,300 kWh a year.
Yours will differ a little.
Which way your land faces moves it, and anything shading it moves it more than that — the design tool runs your own coordinates rather than a town figure.
What the number is worth is the part that changes by street here, because three utilities pay three different things for the same exported kilowatt hour.
Texas law stops an HOA banning solar outright, but lets it keep a ground mount inside a fenced yard and no taller than the fence. What an HOA can and cannot do
Fairview is HOA country — close to eight in ten houses in these ZIPs were built in 2000 or later, the highest share of the six cities we have measured.
Assume an association applies and check the dedicatory instrument early, because we have not found a Town ordinance capping ground-mount height and the association is usually what binds.
Where a fence line does govern, we bring the tilt down on the same frame until the array fits under it — about fourteen degrees puts four modules below six feet.
A flatter array gives up a little production; it does not kill the job.
No holes in your roof, panels aimed south instead of wherever the house faces, and room to add panels when the load grows. Ground mount vs rooftop
$175 for a residential solar PV permit, on the Town's own published fee schedule.
That is unusual — most cities around here price a solar permit off a general fee table or a project valuation, so you do not know the number until you apply.
In Fairview you do.
Not always.
The Town runs a remote virtual inspection programme for solar — photographs and video shot to a published specification and uploaded to the permit, with a signed certification form.
The published picture list was written for rooftop arrays, so for a ground mount we agree the shot list with the department first.
Where that route is available it takes days off the end of the job.
It matters more than any equipment decision.
On Grayson-Collin lines your export nets at the retail rate.
On CoServ it is bought at 8.5 cents against a retail rate around twelve.
On Oncor lines it is whatever your retail plan says.
Your bill names the company, and we confirm it before quoting because it changes what size array is worth building.
It is a constraint, not a wall.
Texas law stops an association banning solar outright, but it lets one confine a ground mount to a fenced yard and cap it at the fence line.
On the acre-plus lots common around Fairview there is normally a screened spot that satisfies both the association and the sun, and we settle that before anyone pours a foundation.
