Exceptional Solar Conditions
| Factor | EPE Territory | National Average |
|---|---|---|
| Peak sun hours/day | ~6.0 | ~4.5 |
| Annual sunny days | ~300+ | ~205 |
| Annual kWh per kW installed | 1,700-1,900 | 1,200-1,400 |
| Solar irradiance | Excellent | Moderate |
Climate Considerations
- Abundant sunshine: 300+ sunny days annually
- Desert climate: Low humidity, clear skies
- Summer heat: High temps slightly reduce efficiency

Net Metering Policy
EPE Net Metering Programs
El Paso Electric's net metering policies vary by state:
| Feature | Texas (El Paso) | New Mexico |
|---|---|---|
| Net metering available | Limited/varies | Yes |
| Credit rate | Check current policy | Retail rate (traditional) |
| System size limit | Varies | 80 MW aggregate cap |

New Mexico Advantage
New Mexico customers benefit from state-mandated net metering rules that provide more favorable terms than Texas. If you're in the Las Cruces area or other NM portions of EPE territory, net metering policies are generally stronger.
Texas Considerations
Texas has a deregulated electricity market in most areas, but El Paso is in a regulated zone served exclusively by EPE. This means EPE's policies apply directly, without retail choice. Check current EPE policies for the latest Texas solar program details.

Frequently Asked Questions
Does El Paso Electric have net metering?
It depends on your state. New Mexico customers have state-mandated net metering with favorable terms. Texas policies are evolving—check current EPE programs for El Paso County.
How much sun does El Paso get?
El Paso averages approximately 6.0 peak sun hours per day and over 300 sunny days annually. This is among the highest solar resources in the United States, rivaling Phoenix and Yuma.
What is the payback period with EPE?
For purchased systems without the federal credit, expect 12-16 years payback. New Mexico customers may see faster payback due to the state tax credit (10% up to $6,000).
Is it better to be in Texas or New Mexico for solar?
For EPE customers, New Mexico has better solar policies: mandated net metering, a 10% state tax credit, and sales tax exemption. Texas offers the property tax exemption but fewer state-level solar incentives.
Can I get the federal tax credit with EPE?
For purchased systems, the 30% federal credit (Section 25D) expired December 31, 2025. For PPA/Lease agreements, the Section 48E credit (30%) remains through 2027—the solar company claims it and passes savings to you.
Does desert heat hurt solar panels?
Extreme heat slightly reduces panel efficiency—typically 0.3-0.5% per degree above 77F (25C). However, El Paso's exceptional sunlight more than compensates for this loss. Production estimates account for heat.
