Question 1

How much does solar cost in Texas?

Accepted Answer

About $2.45 to $3.10 per watt installed for a cash purchase. A typical 8kW system runs roughly $21,760 before incentives and $15,232 after the 30% federal credit. See our Texas solar panel cost guide at /solar-panel-cost-texas.

Question 2

What is a good price per watt?

Accepted Answer

Anything at or below $2.85 per watt from a licensed local installer is competitive in most Texas markets in 2026.

Question 3

Why are some quotes 40% higher for the same panels?

Accepted Answer

Usually financing dealer fees or high-cost sales channels. Ask every installer for the cash price and the financed price separately. Details at /solar-loan-vs-cash.

Question 4

How much does a 5kW system cost?

Accepted Answer

About $13,600 gross and $9,520 after the federal credit. Full breakdown at /5kw-solar-system-cost.

Question 5

How much does a 10kW system cost?

Accepted Answer

About $27,200 gross and $19,040 net. See /10kw-solar-system-cost.

Question 6

What does a solar battery cost?

Accepted Answer

Roughly $11,000 to $16,000 installed for a 13.5 kWh unit, before the 30% credit. See /solar-battery-cost.

Question 7

Are there hidden costs?

Accepted Answer

The common ones are a main electrical panel upgrade ($1,800 to $4,000) and roof work. Both should appear as line items. See /solar-installation-cost.

Question 8

Does a new roof need to come first?

Accepted Answer

If your roof has under ten years of life left, replace it first. Removing and reinstalling an array later costs $2,000 to $6,000.

Question 9

How much will I save with solar in Texas?

Accepted Answer

A household paying $220 a month typically avoids $2,300 to $2,900 in year-one electricity. Run your own numbers at /texas-solar-calculator.

Question 10

What is the typical payback period?

Accepted Answer

Eight to twelve years for a cash purchase, against a 25-year production warranty. Model yours at /solar-payback-calculator.

Question 11

Will solar eliminate my electric bill?

Accepted Answer

Almost never entirely. Base and delivery charges remain, and most homes draw grid power at night without storage.

Question 12

Do savings grow over time?

Accepted Answer

Yes. Texas retail rates have risen around 3% a year long-run, so avoided electricity is worth more each year while your system cost is fixed.

Question 13

Does solar increase home value?

Accepted Answer

Owned systems generally do. Leased systems typically do not and can complicate a sale. See /solar-lease-vs-buying.

Question 14

What if I move?

Accepted Answer

An owned system transfers with the home. A loan must be paid off or assumed at closing; a lease must be transferred or bought out.

Question 15

Is solar worth it if my bill is under $120?

Accepted Answer

Often not. Lower bills stretch payback past twelve years. Check yours at /solar-savings-calculator before committing.

Question 16

What return does solar deliver?

Accepted Answer

Well-priced Texas systems commonly return 150% to 250% of net cost over 25 years. See /solar-roi-calculator.

Question 17

Does Texas have a state solar tax credit?

Accepted Answer

No, because Texas has no state income tax. The state incentives are a property tax exemption and local utility rebates. See /texas-solar-incentives.

Question 18

How does the 30% federal credit work?

Accepted Answer

It reduces federal income tax owed by 30% of your total installed cost, with unused amounts carrying forward. See /federal-solar-tax-credit.

Question 19

Is the federal credit refundable?

Accepted Answer

No. It offsets tax liability rather than generating a refund on its own.

Question 20

Do batteries qualify for the credit?

Accepted Answer

Yes, storage of 3 kWh or more qualifies, even standalone.

Question 21

Will solar raise my property taxes?

Accepted Answer

Not if you file the exemption. See /property-tax-exemption.

Question 22

How do I claim the property tax exemption?

Accepted Answer

File Form 50-123 with your county appraisal district after installation.

Question 23

Are there rebates in my city?

Accepted Answer

Austin Energy, CPS Energy, Denton, and Garland run programs. See /solar-rebates-texas.

Question 24

Can I stack a rebate with the federal credit?

Accepted Answer

Usually yes, though a rebate may reduce the basis used for the federal credit. Ask a CPA.

Question 25

Does Texas have net metering?

Accepted Answer

Not as a statewide requirement. Credit comes from your municipal utility or retail provider's buyback plan. See /net-metering-texas.

Question 26

Who sets my buyback rate?

Accepted Answer

Your retail electric provider in deregulated areas, or your city utility in municipal territory.

Question 27

What does Oncor pay for solar?

Accepted Answer

Oncor delivers power but does not buy it. Your REP sets the rate. See /oncor-solar.

Question 28

How does Austin Energy credit solar?

Accepted Answer

Through a Value of Solar credit per kWh produced, separate from your usage charges. See /austin-energy-solar.

Question 29

How does CPS Energy handle solar?

Accepted Answer

It nets production against usage on the monthly bill and offers a per-watt rebate. See /cps-energy-solar.

Question 30

How long does interconnection take?

Accepted Answer

Two to eight weeks after final inspection, depending on the utility queue.

Question 31

Can I switch electricity plans after going solar?

Accepted Answer

Yes in deregulated areas, but confirm the new plan supports distributed generation and check its export rate.

Question 32

Should I oversize my system?

Accepted Answer

Only if your buyback rate is close to retail. With weak export credit, size closer to daytime self-consumption.

Question 33

How many panels will I need?

Accepted Answer

Most Texas homes need 15 to 30 modern panels. Calculate yours at /solar-panel-calculator.

Question 34

How long do panels last?

Accepted Answer

25 to 30 years with about 0.5% annual degradation. See /learn/solar-panels.

Question 35

Do panels survive Texas hail?

Accepted Answer

Modern tempered-glass modules survive most events. Check the hail rating and confirm insurance coverage.

Question 36

Microinverters or a string inverter?

Accepted Answer

Microinverters for shaded or complex roofs; a string inverter with optimizers is fine on a clean south plane. See /learn/solar-inverters.

Question 37

Do I need a battery?

Accepted Answer

Not for savings in most cases. Batteries are for outage resilience. See /learn/solar-batteries.

Question 38

Will solar work during an outage?

Accepted Answer

Only with a battery and islanding gateway. Grid-tied systems shut down for line-worker safety.

Question 39

How long does installation take?

Accepted Answer

One to three days on the roof, six to twelve weeks total including permits and interconnection. See /learn/solar-installation.

Question 40

How do I vet an installer?

Accepted Answer

Ask for the Texas electrical license number, insurance certificates, workmanship warranty term, and three local references from the past year.
