| Peak sun hours per day | 4.8 – 5.6 |
|---|---|
| Annual kWh per kW installed | 1,400 – 1,650 |
| Typical system size | 8 – 12 kW |
| Electricity rates | Near the national average, but bills run high on summer cooling |
| Export credit regime | No statewide mandate — retailer-specific buyback |
How Texas credits the power you export
Texas has no statewide net metering requirement. In the
deregulated part of the market, individual retail electricity providers offer
their own solar buyback plans, and terms differ wildly — some credit near the
retail rate, some credit a fraction of it, some cap monthly credits. Municipal
utilities and co-ops set their own rules independently.
This makes Texas the state where shopping your electricity plan matters
as much as shopping your installer. A good buyback plan can be worth more
over 20 years than a better price per watt. Confirm the plan's terms — and whether
it can be changed on you at contract renewal — before you size a system around it.
The general mechanics are in net metering explained; this is how they land in Texas.
What a system costs here
Texas pricing sits broadly within the national band of $2.50–$3.50 per watt before incentives, so a typical 8 – 12 kW system lands somewhere around $20,000–$42,000 before credits. Local labour rates, permitting fees and whether you need an electrical panel upgrade move that more than the panel brand does. Full breakdown in what solar panels cost.
Incentives that stack in Texas
| Layer | What it does |
|---|---|
| Property tax | Texas has exempted the added home value from solar from property tax assessment. |
| Utility rebates | Several municipal utilities and co-ops have run their own rebate programmes. Availability is local, not statewide. |
| No state income tax | Which also means no state income tax credit — the federal position is the whole tax story here. |
When solar is a poor fit in Texas
- A cheap fixed-rate electricity plan narrows the savings; solar competes against what you actually pay.
- If your retailer has a poor buyback rate, an oversized array is money spent for very little return.
- Hail is a real consideration in parts of the state — check what your homeowner's policy says about roof-mounted equipment before you install.
The universal disqualifiers apply here too — renting, a roof near end of life, or moving within a few years. See roof age and solar and what happens when you sell.
Texas solar questions
Does Texas have net metering?
Not as a statewide requirement. Buyback is offered plan by plan in the deregulated market and utility by utility elsewhere, and the rates differ substantially. Always confirm the specific plan terms rather than assuming a standard arrangement.
How many solar panels does a Texas home need?
Texas homes often need larger systems than the national average because summer cooling loads are high — 8 to 12 kW is a common range, or roughly 20 to 30 panels. Size it from twelve months of your own kWh, not from a state average.
Will solar help during a grid outage in Texas?
Only with a battery and the right inverter setup. A standard grid-tied array shuts down in an outage for line-worker safety. If outage resilience is the reason you are considering solar, say so early — it changes the design.
