Do I Need a Permit for Solar Panels in El Paso, TX?
El Paso earns its "Sun City" nickname with 3,762 annual sunshine hours—more than Miami, Phoenix, or Los Angeles. This solar resource makes El Paso one of the most productive locations in the country for residential solar, with typical 6-7 kW systems generating 10,000–12,000 kWh per year. El Paso Electric's (EPE) net metering program credits homeowners for exported generation at the retail rate, making solar economics attractive. The federal 30% Investment Tax Credit expired December 31, 2025—but EPE's net metering and the city's abundant sunshine continue to drive solar adoption.
El Paso solar panel permit rules — the basics
Solar panel installations in El Paso require two permits: a building permit covering the structural attachment of the racking system to the roof, and an electrical permit covering the DC and AC wiring. The building permit application requires a site plan, a roof plan showing panel layout, mounting specifications confirming racking attachment to the roof framing (not just to the sheathing), and structural documentation if required. The electrical permit application requires a one-line diagram—a simplified schematic showing the panel string wiring, inverter connections, AC disconnect, and the connection to the home's service panel and EPE's grid connection. Both permits are applied for through El Paso's Citizen Access Portal or at the One Stop Shop at 811 Texas Ave.
El Paso Electric's interconnection process is separate from and parallel to the city permit process. EPE strongly recommends that contractors submit an interconnection application to EPE and receive EPE's design approval before beginning installation. EPE's website states clearly: "If the system is built prior to gaining EPE approval, the customer risks paying for a system that does not meet EPE's interconnection requirements." The interconnection application to EPE requires a one-line diagram and a site diagram (combined file no more than 10 MB). EPE reviews the application and approves the design before the city permits are issued. After the city inspection passes, the contractor contacts EPE at smallrenewables@epelectric.com to request the field inspection and bi-directional meter installation. The system must not be energized (connected to the grid) until after EPE's field inspection and meter swap.
El Paso's solar installer must hold a Texas TDLR electrical contractor license (for the electrical permit scope) and be qualified to install the building permit scope (structural attachment). Many El Paso solar companies hold both licenses in-house or coordinate appropriately. Before signing a solar installation contract, confirm that the company handles both the city permit applications and the EPE interconnection application as part of their service—some installers pass permitting coordination back to the homeowner, creating delays and complications that experienced solar companies avoid.
System size in El Paso is governed by EPE's interconnection requirements: the system may not be designed to produce more than 100% of the previous year's electricity consumption. EPE verifies the one-year consumption against the proposed system output during the interconnection application review. If you've recently moved into the property and have less than one year of consumption data, the solar installer and EPE can work from an estimated consumption calculator. Oversizing a system beyond 100% of consumption is not permitted under EPE's interconnection rules—a constraint that matters for homeowners planning to add significant loads (EV charger, pool) after solar installation, as the system should be sized to include projected future loads.
Why three El Paso solar situations have three different paths
| Variable | How it affects your El Paso solar permit |
|---|---|
| EPE interconnection approval — required before energizing | EPE must approve the system design before installation and inspect the installation before the bi-directional meter is installed. EPE recommends submitting the interconnection application concurrently with city permit applications. System cannot be energized until EPE completes its field inspection. Contact EPE at smallrenewables@epelectric.com after city inspection passes. |
| Building + electrical permits both required | Two El Paso city permits are required: a building permit for racking structural attachment, and an electrical permit for all DC/AC wiring. Both must be issued before installation. Final inspections for both must pass before EPE will schedule its field inspection. The solar installer typically handles both permit applications as part of their service. |
| 100% consumption cap — EPE interconnection rule | EPE limits solar system size to not exceed 100% of the previous year's electricity consumption. If you're planning to add significant future loads (EV charger, pool, home addition), discuss this with your solar installer before system design so the system is sized to include projected loads rather than just current consumption. |
| Historic district — HPO review for visible panels | Solar panels visible from public streets in El Paso's nine historic districts require HPO administrative review. Rear-slope placements invisible from the street typically receive administrative approval (2–3 weeks). Front-slope or street-visible placements require closer review under HPO's solar compatibility guidelines. Contact HPO at (915) 212-1567 before finalizing panel placement layout in any historic district. |
| Federal ITC expired December 31, 2025 | The 30% federal Investment Tax Credit for residential solar expired at the end of 2025 under the "One Big Beautiful Bill." New El Paso solar installations in 2026 do not qualify. EPE's net metering, Community Solar program, and EPE's own Texas Residential Solutions rebate program (check current availability at epelectric.com) remain as El Paso-specific incentives. |
| September 2025 fee schedule | Building permit fees are valuation-based (charged at plan submittal). On a $22,000 solar installation, combined building and electrical permit fees run approximately $350–$550. The electrical permit component is approximately 20% of total fees. Contact the One Stop Shop for a specific fee estimate before submission. |
El Paso solar economics after the federal ITC — what the numbers look like now
The expiration of the 30% federal Investment Tax Credit at the end of 2025 significantly changed the economics of residential solar in El Paso. A typical 7 kW El Paso solar system runs $18,000–$25,000 installed. Without the ITC, this cost is the homeowner's full cost; with the ITC (pre-2026), the net cost after the credit was $12,600–$17,500. The ITC's expiration extended payback periods from approximately 7–10 years to approximately 10–15 years at current electricity rates and EPE's net metering structure.
El Paso's solar economics still have several factors working in the homeowner's favor despite the ITC expiration. EPE's retail electricity rates have been rising—El Paso's rates, while historically lower than national averages, have increased as EPE invests in grid modernization. A fixed-cost solar system provides a hedge against future rate increases over a 25-year panel lifespan. El Paso's 3,762 annual sunshine hours mean systems produce at or near their rated capacity more consistently than in cloudier cities—a 7 kW El Paso system generates 10,500–11,500 kWh annually, compared to 8,500–9,500 kWh for the same system in Nashville. EPE's net metering credits exported generation at the full retail rate (not a reduced "avoided cost" rate), which maximizes the value of each exported kWh. And the $30.25 minimum monthly bill applies regardless of exports, which is an important constraint for homeowners who export significant power.
EPE's Community Solar program offers an alternative for El Paso homeowners who can't install rooftop panels (renters, shaded roofs, homeowners who don't want the installation complexity): subscribing to EPE's utility-owned solar facilities provides bill credits from solar generation without rooftop panels. Community Solar doesn't require building permits or EPE interconnection—it's a subscription service. For homeowners who have concerns about installation complexity, roof condition, or HOA restrictions, Community Solar provides access to El Paso's abundant solar resource without the capital investment of a rooftop system.
What El Paso solar inspectors check
El Paso building inspectors verify the structural mounting of the solar racking. The inspector confirms that lag screws or other mounting hardware penetrate into the roof rafters (not just the sheathing), that flashing around roof penetrations is properly installed to prevent water infiltration, and that the racking is mounted level and secure. El Paso's monsoon season delivers high wind and rain events; the inspector verifies that the racking's wind uplift resistance meets code requirements for the local wind exposure. For flat roof ballasted systems, the inspector may verify the ballast weight distribution and confirm no roof penetrations are hidden or inadequately sealed.
The electrical inspector checks the DC wiring—panel string connections, combiner box if present, conduit types and routing—the inverter installation and clearances, the AC disconnect installation and labeling, the connection to the service panel (verifying the correct breaker size for the inverter's output), and the rapid shutdown system. NEC Article 690.12 requires rapid shutdown for all rooftop solar systems—automatically de-energizing the DC conductors within 30 seconds of a shutdown command to protect firefighters. El Paso inspectors specifically verify rapid shutdown labeling at the service panel, inverter, and on the roof, and may functionally test the rapid shutdown system before passing the electrical inspection.
After both the building and electrical inspections pass, the contractor contacts EPE. EPE conducts its own field inspection to verify that the installed system matches the approved interconnection application specifications—panel count, inverter model, disconnect location, and meter socket compatibility. If the installed system differs from what was approved in the interconnection application (for example, the contractor substituted a different inverter model), EPE may require a revised interconnection application before completing the meter swap. Prevent this by confirming the installed equipment matches the EPE-approved one-line diagram before requesting the EPE field inspection.
What solar panels cost in El Paso, TX
El Paso solar installation costs are competitive with other Sun Belt markets. A complete residential rooftop solar installation in El Paso in 2025-2026 runs approximately $2.70–$3.40 per watt installed by a licensed contractor. Typical systems: 5 kW system, $13,500–$17,000; 7 kW system, $18,900–$23,800; 9 kW system, $24,300–$30,600. Without the federal ITC, these are the full homeowner costs. Battery storage (e.g., Tesla Powerwall or similar) adds $10,000–$15,000 per battery unit installed. El Paso's abundant sunshine means smaller systems provide meaningful bill offsets; a 5 kW system in El Paso generates approximately 7,500–8,500 kWh annually—covering 60–80% of the average El Paso home's electricity consumption.
City permit fees for El Paso solar: building and electrical permits combined, approximately $350–$600 for a typical residential system. These are charged at plan submittal. EPE interconnection: no government fee for standard residential systems. The solar installer typically handles both permit applications and the EPE interconnection application as part of their service price—confirm permit inclusion when comparing bids.
What happens without a permit for El Paso solar panels
Installing solar panels in El Paso without the required city permits creates a specific practical problem: EPE will not install the bi-directional meter for a system that has not received final inspection from the city's building and electrical inspectors. EPE's interconnection process requires proof of the city's final inspection before EPE will conduct its own field inspection and meter swap. A solar system installed without permits physically cannot be connected to the grid for net metering—it can only operate as an off-grid battery system (if batteries are included) or be completely non-functional as a grid-tied system.
At resale, an unpermitted solar system is a disclosure and valuation issue in El Paso's real estate market. A solar system that cannot be verified as properly permitted and EPE-interconnected is a liability rather than an asset in a home sale. The buyer's lender may not include its value in the appraisal. Texas disclosure law requires sellers to disclose known material conditions; an unpermitted solar system without EPE interconnection is a material condition. For the city permit fees of $350–$600 that are the gateway to a properly functioning and grid-connected solar system, there is no argument for bypassing the permit process.

Common questions about El Paso solar panel permits
Does El Paso Electric (EPE) need to approve my solar system before installation?
EPE strongly recommends—and effectively requires—submitting an interconnection application to EPE and receiving EPE's design approval before installation. EPE's website states that "if the system is built prior to gaining EPE approval, the customer risks paying for a system that does not meet EPE's interconnection requirements." The EPE interconnection application requires a one-line diagram and site diagram. Submit it to EPE concurrently with the city permit applications. EPE's design review typically takes 10–14 days. After the city inspection passes, contact EPE at smallrenewables@epelectric.com to request the field inspection and meter swap.
What is El Paso Electric's net metering rate for solar?
EPE's net metering rate credits excess solar generation against your electricity consumption at the retail rate—the same rate you pay for electricity you consume from the grid. This is a favorable full retail rate credit, as opposed to the reduced "avoided cost" rate some utilities offer. The program has a $30.25 minimum monthly bill, meaning your bill will be at least $30.25 per month regardless of how much you export. EPE's net metering terms may change; verify current program details at epelectric.com before finalizing your system design. EPE is not affiliated with Texas's deregulated electricity market—EPE operates as the regulated monopoly utility for its service territory in West Texas and Southern New Mexico.
Does the federal 30% solar tax credit still apply to El Paso installations?
No. The federal Investment Tax Credit (ITC) for residential solar—which provided a 30% credit of the system cost—expired on December 31, 2025 under the "One Big Beautiful Bill" signed in July 2025. New solar installations in El Paso in 2026 and beyond do not qualify for the federal ITC. El Paso's local incentives—EPE net metering, EPE's Texas Residential Solutions rebate program (verify current availability at epelectric.com), and EPE's Community Solar subscription program—remain available. Consult a tax professional for current federal energy incentive status before making solar installation decisions.
How long does the El Paso solar permit and EPE interconnection process take?
A well-organized El Paso solar installation follows this timeline: EPE interconnection application submitted concurrently with city permit applications (Day 1); EPE design approval in approximately 10–14 days; city building and electrical permits issued in 2–3 weeks; installation (1–2 days); city building and electrical inspections (1–2 days after installation); EPE field inspection request submitted (same day); EPE meter swap scheduled (typically 1–3 weeks after EPE inspection request); Permission to Operate (PTO) granted. Total from first application to PTO: approximately 6–10 weeks for a straightforward installation. Historic district properties add 2–3 weeks for HPO review before city permits.
Can I install solar panels on an El Paso historic district home?
Yes, with HPO review. El Paso's Historic Preservation Office reviews solar panel placement for properties in designated historic districts. Panels on rear-facing roof slopes not visible from public streets typically receive administrative HPO approval in 2–3 weeks at no fee. Panels on front-facing or prominently street-visible roof slopes receive closer review under HPO's design compatibility guidelines, which balance solar access with preservation goals. Contact the HPO at (915) 212-1567 before finalizing your panel layout to confirm which review track applies and whether the proposed placement is administratively approvable.
What is EPE's Community Solar program as an alternative to rooftop panels?
EPE's Community Solar program allows El Paso customers to receive bill credits from EPE-owned solar facilities without installing rooftop panels. Subscribers receive a portion of their electricity from community solar and receive corresponding credits on their bills. There's no rooftop installation, no city permit, no EPE interconnection application—just a subscription. Community Solar is available to both homeowners and renters, making it accessible to El Pasoans who can't install rooftop panels due to roof condition, shading, HOA restrictions, or rental status. Subscription waitlists may apply; check epelectric.com for current availability and subscription details.
