How to choose a solar installer in Montana
Check licensing & certification
Solar installs in Montana 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 Montana 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 Montana

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.
