Solar Panel Cost in El Paso, Texas (2026)

Installed residential solar in Texas runs roughly $2.20 to $2.80 per watt before incentives. In El Paso that puts a typical 8 kW system somewhere around $17,600 to $22,400, and a 12 kW system around $26,400 to $33,600. If your quote sits inside that band, the hardware price is not your problem.

Your problem is the rate you'll be on after it turns on.

El Paso is the Texas city where the least of the standard Texas solar advice applies. Like Austin and San Antonio it has no retail choice — but unlike anywhere else in the state it is served by a regulated, vertically integrated utility outside ERCOT, on the Western Interconnection, with a mandatory demand charge on rooftop solar. Per the PUCT's own Scope of Competition report, El Paso Electric is "the only investor-owned vertically-integrated utility in Texas that is a member of WECC," and its customers "do not have a choice of provider." No retail choice. No ERCOT wholesale plans. No TDU delivery charges on your bill.

And since May 1, 2026, every non-grandfathered rooftop solar customer in EPE's Texas territory is on a mandatory Distributed Generation Rate carrying a $5.65 per kW demand charge. That single line item does more to decide whether your system pays off than anything on the installer's price sheet.

So: best sun in Texas, and arguably the least forgiving residential solar tariff in Texas. That's the whole story of this page. For the statewide baseline, start with the Texas solar cost guide — then come back here, because El Paso is the exception to most of it.

What a system costs in El Paso, by size

That last column is real and it is specific to here. The City of El Paso's Schedule C fee list prices solar electrical permits at a $110 non-refundable base fee plus $14 per solar panel, "based on quantity plus base fee and applicable technology fee." Most cities charge a flat or valuation-based permit fee. El Paso charges you by the module, so permit cost scales linearly with array size.

Three honest caveats on that column:

• The $110 / $14-per-panel figures come from the most recent machine-readable edition of the City's Schedule C I could read (FY 2024). The current FY 2027 schedule is published as a scanned image with no text layer, and the City's own "Current Schedule C" link returns a 404. Treat these as last-confirmed, not current. Call the One Stop Shop at 811 Texas Ave, (915) 212-0104, and get the current per-panel number in writing.
• There is also a $200 residential submittal fee deposit charged at plan submittal (credited toward the permit fee), effective September 1, 2025, plus an optional $200 expedited plan review. Permits are filed through the Accela Citizen Access portal or in person.
• The FY 2024 schedule lists solar under Electrical, Mechanical, Plumbing and Building permits, which implies more than one permit type may apply to a rooftop array. I could not find a City document that states the exact required permit set for residential rooftop PV. Ask your installer to list every permit they're pulling and what each costs.

One design detail worth knowing: El Paso's currently adopted electrical code is the 2020 NFPA 70 (NEC), alongside the 2021 IBC, IRC, IECC and IFC. Rapid-shutdown and PV circuit design here answers to NEC 2020, not the 2023 edition a lot of national guides assume.

The charge that actually decides your payback: $5.65 per kW

EPE's residential tariff (Schedule No. 01) now contains a Distributed Generation Rate. Read the applicability line carefully: "The Distributed Generation Rate is applicable to all non-grandfathered DG customers." It is not a plan you choose. Install solar, and it is your rate.

It has a customer charge of $13.71 per meter per month and a demand charge of $5.65 per kW — the same amount in summer and non-summer. Here is how the tariff defines the kW it bills you on:

"Maximum demand is defined as the highest measured sixty (60) minute interval kilowatt (kW) load during the billing period. Monthly billing demand will be the maximum demand."

Three things follow from that sentence, and they are the whole ballgame:

1. One hour sets the month. Not your average. Not your total kWh. The single worst 60-minute stretch of grid draw.
2. There is no time-of-day window. A 3 a.m. peak counts exactly the same as a 5 p.m. peak. Charging an EV overnight while the dryer and the AC are running will set your demand charge just as surely as a hot afternoon.
3. Solar production does not obviously help at the peak hour. If your worst hour is after sunset, your panels contributed nothing to lowering it.

The arithmetic, straight off the $5.65/kW rate:

Solar United Neighbors has reported the charge running "$28.50 to $47.50 for most DG customers" per month. That back-solves to peaks of roughly 5 to 8.4 kW, which lines up with the tariff — so I'm treating both figures as sound.

El Paso Matters reported one homeowner who installed in 2022 and watched a typical ~$30 bill become $117 in May 2026, while charging an EV overnight "during off-peak hours." Under a demand charge with no time window, off-peak charging buys you nothing.

The trade EPE made, which no savings calculator models

The DG Rate's energy charges are exactly 3.333 cents per kWh lower than standard residential in every tier: DG summer first 600 kWh is $0.09564 against the standard $0.12897; DG non-summer is $0.07564 against $0.10897. EPE moved volumetric revenue into the demand charge.

Which means a self-consumed kWh is worth about 3.3 cents less to you than the same kWh is worth to your non-solar neighbor. Every generic "your electricity costs 15 cents, so each solar kWh saves you 15 cents" calculation is wrong in El Paso by roughly a fifth, before you even get to the demand charge.

What an exported kWh is worth here: about 1.6 cents

Texas has no statewide net metering, and El Paso doesn't have the workaround the rest of the state uses. In Houston, Dallas or Corpus Christi you can shop retail providers and pick a solar buyback plan. In El Paso you cannot switch providers at all, so that entire strategy is unavailable to you. If a salesperson pitches you a buyback plan in El Paso, they don't know your market.

What you get instead is EPE's Schedule No. 48. For systems of 100 kW or less — every residential system — EPE pays:

"the lesser of the Company's cost of fuel and purchased power per kilowatt-hour (kWh) for the billing month in which the energy was received or, the Company's avoided energy cost..."

EPE's published 2026 Effective Purchased Power Factor for Method A / net-metered service at secondary (residential) voltage is $0.016154/kWh for March through September 2026. Call it roughly 1.5 to 2 cents — and I'd hold it loosely, because EPE publishes a second table of purchased-power adjustment factors on the same page and does not spell out the netting arithmetic. Ask EPE to confirm your actual per-kWh export credit in writing before you size anything around exports.

Against an all-in retail rate around 15 cents, that's close to a 9-to-1 haircut. Compared to what a self-consumed kWh saves you on the DG rate (~11.8 cents right now), it's still roughly 7-to-1.

The 10% cap almost nobody mentions

Schedule 48 also says this, and it is the most-missed provision in El Paso:

"Measured net production shall be purchased... and is limited, on an annual basis, to ten percent of the Customer's annual kWh consumption prior to service under this rate schedule."

EPE will buy exports equal to at most 10% of what you used the year before you went solar. Past that, additional export has no purchase obligation behind it. Combined with the statutory condition that EPE's net-metering option is only available where the system is rated at or below your prior-year consumption (Texas Utilities Code §39.554(e), which also sets the 50 kW cap — long-standing statute, not a new EPE policy), oversizing for export income in El Paso is pointless. The economics here point toward self-consumption, not production.

On credit balances: amounts of $50 or less roll to the next bill; anything above $50 is refunded by check.

The bill floor solar does not eliminate

In the rest of Texas, the piece solar can't touch is the TDU delivery charge — Oncor, for instance, publishes $4.06/month plus 6.0295 cents/kWh for 2026, so 1,000 delivered kWh carries $64.36 in delivery. Those charges are set by the PUCT, not by a retail provider, and they are revised on the PUCT's schedule — March 1 and September 1, not the installer's. If your quote was written by a company that mostly works Dallas or Houston and it references TDU charges, that's a tell — there is no TDU on an El Paso bill.

El Paso's version of the unavoidable floor is bigger. Every month, regardless of production:

• $13.71 customer charge
• $2.70 AMS surcharge per residential meter (billing months January 2023 through December 2027)
• $5.65 × your peak kW demand charge

The two fixed items alone are $196.92 a year. Add the demand charge at the reported typical range of $28.50–$47.50/month ($342–$570/year), and you're looking at roughly $540 to $770 a year that solar does not remove. At a 10 kW peak it's closer to $875. Any 25-year savings model that doesn't carry that line is overstating your return.

Do not size a system off an August–October 2026 bill

Two temporary riders are cancelling each other out on your bill right now, and one of them is about to lapse.

• Schedule RBRS, the Relate Back Revenue Surcharge: +$0.01924/kWh for twelve months starting August 1, 2026, collecting ten months of retroactive rate-increase revenue (residential class balance: $48,959,313). It shows on your bill as its own line, "Relate Back Revenue Surcharge."
• A temporary fuel refund (Schedule 98-FIRS): −$0.019402/kWh, effective August 17, 2026, for three months only.

Those nearly cancel. When the refund lapses — roughly mid-November 2026, though verify the end date on your own bill — your effective rate jumps about 1.94 cents/kWh with no rate case involved.

Here's the current stack, summer first-600-kWh tier, standard residential (my arithmetic on EPE's published components): $0.12897 energy + $0.016154 fixed fuel + $0.000687 EECRF + $0.00349 GCRR + $0.001825 RPRF + $0.000361 rate case expense surcharge = $0.151487, then +$0.01924 RBRS − $0.019402 refund = about $0.1513/kWh today, and about $0.1707/kWh once the refund lapses. Non-summer: about $0.1313 now, $0.1507 after. Subtract the DG rate's 3.333-cent-lower energy charge and a solar customer sees roughly $0.1180/kWh summer and $0.0980/kWh non-summer today, rising to about $0.1374 summer and $0.1174 non-summer once the refund lapses.

I did not price two smaller live riders (the COVID-19 asset surcharge and MBDRF), so those figures are slightly understated. Treat them as a floor, not a quote.

The practical point: a proposal built on an August, September or October 2026 bill will understate your rate. Ask for the model to be re-run at the post-refund rate.

El Paso has the best sun in Texas — and that part is real

NASA's POWER dataset (20-year climatology, 2001–2020, global horizontal irradiance) puts El Paso at 5.90 kWh/m²/day annually, against Dallas at 4.71, Houston at 4.65, Austin 4.81, San Antonio 4.84, Corpus Christi 4.87, Lubbock 5.35 and Midland 5.58. That's roughly 27% more sun than Houston and 25% more than Dallas. The seasonal swing is steep: 8.13 in June, 3.40 in December — December is about 42% of June.

One caution I want to be blunt about: that is irradiance, not system output. It is not a kWh-per-kW production figure and it should not be multiplied by your system size. If a proposal gives you an annual kWh number, ask which modeling tool produced it (PVWatts, Helioscope, Aurora), at what tilt, azimuth, shading and system-loss assumptions, and get the file.

What is actually in effect versus what was only proposed

This market has been the subject of a genuinely contested rate proceeding, and a lot of what's floating around online is either stale or is a proposal being reported as policy. What I can and can't verify:

The $30.25 rooftop solar minimum bill is gone from the tariff. It no longer appears in Schedule 01. DSIRE — the database most solar blogs copy from — still lists it as current and never mentions the demand charge or the 10% export cap. Any 2026 article citing a "$30.25 minimum bill" for El Paso is working from stale data.

The SOAH judges recommended against changing the minimum bill. According to the City of El Paso's February 18, 2026 news release describing the SOAH judges' December 2025 Proposal for Decision, the judges recommended "no rooftop solar minimum bill changes: keep the current minimum bill in place pending further review." The PUCT went the other way. Citing the PFD as the outcome would be a serious error.

HB 912 did not reverse the demand charge. HB 912 (89th Legislature) passed the House 148-0 and the Senate 31-0, and took effect September 1, 2026. It now requires the PUCT to make a utility "conduct and submit... a comprehensive cost-benefit analysis" before approving an alternative DG compensation method or DG-only fee. But EPE filed this rate case in January 2025; the PUCT issued its final order in Docket No. 57568 in early 2026 (news coverage reports February; I could not retrieve the order itself to confirm the signature date); it hit bills May 1, 2026. The new requirement came later. Advocates are pressing for a cost-benefit analysis. The charge stands unless and until the PUCT changes it.

What I could not verify, and won't pretend otherwise: Docket No. 57568 is still procedurally live. The City of El Paso sought rehearing on March 2, 2026, and the PUCT's June 18, 2026 open meeting agenda listed an "Order on Rehearing" for the docket. I could not read that order — the PUCT filings interface blocked every retrieval method I tried. So I will not tell you the rehearing left the demand charge untouched. What I can tell you is that the $5.65/kW DG Rate is what EPE currently publishes in the Schedule 01 revision posted August 1, 2026. Before you sign, pull that tariff yourself from epelectric.com and confirm it's still what's there.

Worth knowing: EPE's own homeowner-facing "Residential Consumer Guide to Solar Power," still linked from its Rooftop Solar page, is dated March 2022. It predates this entire rate change. The utility's consumer education is four years behind its own tariff.

Interconnection, and two gotchas that are pure El Paso

EPE's interconnection fees are published and small: $85 for a facility rated 100 kW or less, $42.50 for an expansion. Pre-interconnection study fees are waived for pre-certified inverter-based units up to 20 kW connected to a distribution network — which covers most homes, but confirm your equipment is on the pre-certified list, because if it isn't, an exporting 0–10 kW system can carry a study fee of $259 or more.

The sequence: EPE design approval → City permits → install → City final electrical inspection → your contractor emails EPE for the field inspection and meter swap → EPE installs a bi-directional meter → EPE returns the fully executed agreement. Do not energize before the meter swap.

Two local traps:

1. Going solar removes you from Budget Billing and from the Texas Community Solar Program — automatically. EPE states it plainly. That stings more here than anywhere else in Texas: the demand charge makes bills volatile month to month, and level-pay is exactly the tool that would have smoothed it. You lose the smoothing at the same moment you acquire the volatility.
2. The old water-heater meter. Plenty of older El Paso homes have a separate legacy off-peak water-heater meter. It must be rewired and formally removed before you request the EPE solar field inspection, or the inspection is blocked. EPE's instruction is explicit: rewire first, then call Customer Care at (915) 543-5790 to request removal. This is a schedule-killer that no out-of-town installer will know about.

If your home already has solar, or you're buying one that does

Grandfathering is worth real money and it has a trapdoor. Customers whose interconnection application was submitted and accepted by EPE before December 17, 2017 are exempt from the DG Rate for 20 years from interconnection, and that grandfathering runs with the premises to later owners for the remainder of the term.

You can add panels or add battery storage without losing it (the amendment fee is capped at 50% of a new interconnection fee). But cancelling the interconnection agreement and completely removing the existing system forfeits grandfathering permanently. If you're re-roofing, replacing an aged array, or buying a legacy solar home, that's a five-figure decision hiding in the paperwork. Ask EPE in writing what the interconnection date on the premises is before anyone touches the system.

Incentives that actually exist in El Paso in 2026

The 30% federal residential credit (Section 25D) terminated December 31, 2025. A 2026 cash or loan purchase gets no personal federal tax credit. If a proposal still shows a 30% federal credit line, that is not a rounding error — it's tens of thousands of dollars of fictional savings, and it's the single biggest red flag on a 2026 quote. A lease or PPA provider may be claiming a different, commercial credit on their own return; whether any of that value reaches you depends entirely on the contract language and is not automatic.

The Texas property tax exemption is real and it's yours to claim. Tax Code §11.27 exempts 100% of the appraised value added by a solar energy device used primarily for on-site energy. You claim it on Comptroller Form 50-123, filed with the El Paso County Appraisal District — not with the Comptroller, not with the IRS. Nobody files it for you. More on the statewide picture in the Texas incentives guide.

There is no Texas state solar rebate and no state income tax credit. As for EPE: I found only energy-efficiency rebates (evaporative and refrigerated cooling), no current residential solar or battery incentive. I did not exhaustively check every EPE program page, so ask them directly rather than taking my word for it.

One rider almost never mentioned in solar content: EPE's Low Income Rider waives the $13.71 customer charge for qualifying SNAP-matched households in El Paso, Hudspeth and Culberson counties. If that's your household, ask about it whether or not you go solar.

Questions to ask before you sign, in El Paso specifically

1. "Show me the Distributed Generation Rate in your model." Not the standard residential rate. Point at where the $5.65/kW demand charge and the 3.333-cent-lower energy charges appear. If the model doesn't contain them, it is not a model of your bill.
2. "What monthly peak kW did you assume, and where did that number come from?" The demand charge is set by one 60-minute interval. If they can't tell you the assumed peak, they can't tell you your savings. Ask for the savings figure at 5 kW, 7 kW and 9 kW peaks so you can see the sensitivity.
3. "What export credit per kWh did you use?" If the answer is anywhere near retail, walk. EPE's published Method A factor for 2026 is about 1.6 cents.
4. "Does your model respect the 10% annual export purchase cap in Schedule 48?" Most national modeling software has no idea this provision exists.
5. "Was this built off a bill dated August, September or October 2026?" If yes, the fuel refund made my rate look artificially low. Re-run it at the post-refund rate.
6. "What is your plan for the demand charge?" A battery is the only thing that directly attacks a demand charge, and whether it pencils depends on how big your peak actually is and what the battery costs. Anyone who tells you solar alone eliminates the demand charge has not read the tariff.
7. "Does this address have a legacy water-heater meter?" If nobody on the crew knows what you're talking about, they haven't done El Paso.
8. "Which permits are you pulling, and what does each cost?" Per-panel electrical fees, the $200 submittal deposit, and any additional permit types — itemized.
9. "Show me the End-Use Customer Acknowledgement Regarding Rates." This is the one I'd push hardest on. EPE requires you personally to sign a form acknowledging that its "rates, charges, and fee structures are subject to change at any time" and that such changes "could affect the economics... including the magnitude and existence of any net savings on my bill." If a salesperson has told you your rate is locked in, they've been contradicted by a document you are about to sign with your own hand.

One scheduling note for a market that runs on out-of-town call centers: El Paso is on Mountain time, an hour behind the rest of Texas. EPE's own tariff writes it into the optional time-of-day rate, whose on-peak window is 2:00 to 7:00 p.m. Mountain Daylight Time, weekdays, summer only.

The honest summary

El Paso has the best solar resource of any major metro in Texas. It also has, since May 2026, a mandatory demand charge, an export credit near 1.6 cents, and a 10% cap on how much export the utility will even buy. Those facts don't make solar a bad decision here. They make it a different decision — one built around self-consumption and peak management, not around exporting to the grid, and one where a national savings calculator will be wrong by a wide margin.

The good news: the hardware price band is the same as the rest of Texas. If you're inside $2.20–$2.80 per watt, you're paying a fair price for the equipment. What you need checked is everything after that.

I'm an independent solar broker. I don't install anything, I have no crew in El Paso, and I don't get paid by whoever quoted you. Send me the quote and I'll read it for free — I'll tell you whether the modeling accounts for the DG Rate, what export credit they assumed, whether the numbers came off a fuel-refund month, and whether the price holds up. If it's a good deal, I'll say so and you should sign it.
