How to choose a solar installer in Louisiana

Check licensing & certification

Solar installs in Louisiana involve electrical work, so the contractor (or their electrician) needs the proper state license. Favor companies with NABCEP-certified staff, the industry's recognized credential, and confirm they carry liability insurance and a workmanship warranty, not just the manufacturer's panel warranty.

Get three quotes and compare price per watt

Quotes vary widely. Compare the total cash price divided by system size (dollars per watt) rather than the monthly financed payment, which can hide markups. Make sure each quote lists the same panel and inverter brands, the production estimate, and exactly what's included.

Confirm permits, interconnection & net metering

A reputable installer pulls the building/electrical permits and files the utility interconnection paperwork for you. Ask how net metering works with your local Louisiana utility: it determines how much credit you earn for excess power you send back to the grid, which drives your real savings.

What to know before hiring in Louisiana

The largest utilities serving Louisiana homes are Entergy Louisiana (957,522 residential customers, 11.1¢/kWh), Cleco Power (251,927 residential customers, 12.3¢/kWh) and Southwestern Electric Power (207,011 residential customers, 13.5¢/kWh). Your utility sets the rate your solar production offsets, and it is also who an installer files interconnection or service paperwork with, so name it when you ask for quotes.

Check the license before you sign

Electrical contractors in Louisiana are licensed by the Louisiana State Licensing Board for Contractors. Electrical work over $10,000 needs a Commercial contractor license with an electrical classification; journeyman and master electricians are licensed by parishes and cities.

Frequently asked questions

Get at least three written quotes, confirm the company holds the licenses Louisiana requires for electrical and solar work, check that they pull permits and handle the utility interconnection, and look for NABCEP-certified installers. Compare total price per watt, the equipment brands offered, and the workmanship warranty, not just the monthly payment.
