Payback lengthens with size here: exported power is credited at an avoided-cost rate well below retail, so oversizing has a smaller payoff than under true net metering.
What makes El Paso different
1. El Paso Electric sets the interconnection rules
El Paso sits in El Paso Electric territory. Interconnection, the export credit rate and any capacity caps all come from that utility and are subject to change — confirm the current rules before signing a contract.
2. Export credit treatment matters more than panel brand
How exported power is credited has a bigger effect on payback than which panels you buy. Size to your own annual usage first, then pick equipment.
3. Exported power is credited at avoided cost
El Paso sits in an avoided-cost regime: exports are valued below retail, often well below. Batteries that let you self-consume instead of export carry more value here than in a true net-metering market.
4. Heat cuts real output
Panels lose roughly 10–15% of nameplate output above 25°C, and El Paso summers are hard on them. The 1850 kWh per kW figure on this page already reflects local conditions — a national-average calculator will overstate your output.
5. Low local rates mean size discipline matters
At about 13¢/kWh, El Paso has cheap power by national standards. Cheap rates stretch payback, so an oversized system hurts more here than in a high-rate market. Match the array to your own annual usage.
What affects your price in El Paso
- System size — the single biggest driver.
- Roof pitch and height — steep or two-storey roofs add labour.
- Roof age — replace worn shingles first; re-roofing around panels costs more later.
- Panel and inverter tier — premium modules and microinverters add 15–25%.
- Main panel upgrade — older homes may need a 200A service upgrade, $1,500–$3,000.
- Battery — optional, roughly $10,000–$15,000 installed.
- Season — late autumn and winter installs are often cheaper.
