Solar when TNMP delivers your power.

Is TNMP your delivery utility?

Look for TNMP or Texas-New Mexico Power next to the delivery charges on your bill. Your bill is the authority on who serves your home. If another company, a cooperative or a city utility is named, see the utilities directory instead.

Connecting and permission steps

TNMP's page says the installer applies through its online portal and the homeowner confirms the installer is authorized.

Roof readiness before solar

Panels stay on the roof for many years. An in-person check of the roof covering, the decking and the flashing comes before any design. See check the roof before panels.

Documents to gather

• A recent electric bill showing your retail provider, plan and delivery charges
• A year of usage, if your provider shows it
• Any roof inspection report, repair records or roof age
• Every proposal and contract you have received, including financing terms

Questions to ask

1. Has someone checked my roof in person, and does it need work before panels go on?
2. Which way does the roof face, what shades it, and how long is it likely to stay in service before work is needed?
3. Who submits the application to TNMP, and who tells me when written authorization arrives?
4. Which retail electric provider plan are your numbers based on, and what does it pay or credit for exported energy?
5. Which charges on my bill stay the same with solar?
6. Who removes and reinstalls panels if the roof needs work later, and who pays?
