El Paso ranks among the top U.S. cities for solar energy production. With an average of 297 sunny days per year, some of the highest solar irradiance in the country, and electricity rates from El Paso Electric (EPE) that have risen steadily over the past decade, the economic case for residential solar has never been stronger. Here's a complete analysis of whether solar makes financial sense for your home.
El Paso's Solar Advantage
Solar panels produce electricity proportional to sunlight intensity and duration. El Paso receives approximately 5.5 peak sun hours per day on average — among the highest in the continental United States, exceeding Denver, Phoenix, and all of the Southeast. A 6-kilowatt system in El Paso will produce roughly 9,000–10,000 kilowatt-hours per year, compared to perhaps 7,000 in a less sunny market.
El Paso Electric Rates and Time-of-Use Pricing
EPE's residential rates have increased approximately 3–4% annually over the past five years. As of 2026, the average residential rate in El Paso is approximately $0.12–$0.14 per kilowatt-hour, with time-of-use (TOU) plans charging higher rates during peak demand periods (typically 3–7 PM on weekdays). Solar production peaks at midday, which partially offset TOU pricing penalties but doesn't perfectly align with peak rate windows — a consideration when sizing a system and deciding whether to add battery storage.
System Cost vs. Savings
A typical 6 kW residential solar system in El Paso costs $15,000–$22,000 before incentives. The federal Investment Tax Credit (ITC) reduces your federal tax liability by 30% of the installed cost — bringing a $18,000 system down to an effective cost of $12,600. New Mexico and Texas offer limited additional state incentives, though Texas has no state solar tax credit.
At an average EPE rate of $0.13/kWh and 9,500 annual kWh of production, a 6 kW system saves approximately $1,235 per year in electricity costs. This assumes EPE's net metering arrangement, which credits excess production back to the grid at retail rates — confirm the current net metering policy with EPE before purchasing, as policies can change.
Payback Period Analysis
- System cost (after 30% ITC): ~$12,600
- Annual electricity savings: ~$1,235/year
- Simple payback period: approximately 10–11 years
- With 3% annual electricity rate increases: payback improves to 8–9 years
- System lifespan: 25–30 years (with 80% output at year 25)
- Net lifetime savings after payback: $15,000–$20,000 over system life
Impact on Home Resale Value
Multiple studies, including Lawrence Berkeley National Laboratory's Selling into the Sun report, have documented that owned solar systems increase home sale prices. The national average premium is approximately $4/watt of installed capacity — meaning a 6 kW owned system could add $24,000 in sale value. In El Paso, where solar production is exceptionally high, the premium tends to be at or above the national average.
Leased vs. Owned Solar: The Critical Distinction
This is the most important decision in the solar process from a real estate perspective. Owned systems — purchased outright or financed with a loan — add to home value and transfer to the buyer at sale. Leased systems and Power Purchase Agreements (PPAs) do NOT add to home value and often complicate sales because buyers must either assume the lease agreement or it must be bought out at closing.
Leases and PPAs are frequently offered by large national solar companies as a 'no money down' option. The monthly payment may be lower than your electricity bill, but you're essentially renting panels. If you plan to sell within 7–10 years, a lease or PPA can be a serious liability. Always choose an owned system if your finances allow it.
Battery Storage Considerations
The addition of a battery system (such as Tesla Powerwall or Enphase IQ) adds $10,000–$15,000 to system cost but provides energy independence during outages and allows you to store peak production for use during evening TOU peak windows. In El Paso, where grid outages are relatively infrequent, the financial payback on battery addition alone is typically 15+ years — it's more of a resilience purchase than a pure financial one.
