The only requirement to appear on this page is a checked state electrical license, confirmed against the state licensing board as part of our approval process, that's why every listing above shows "License checked." Installers are listed alphabetically by default, not ranked by quality, and no installer pays for placement in that order. LumoWatt does not sell ranking. If paid placement is introduced, it will be clearly labeled and will not change the standard list order. Use the sort dropdown above to re-order the list yourself by years in business or how recently we checked a listing. See our editorial policy and listing standards & verification methodology for the full details.

Central and southern Arizona (Phoenix, Tucson) see significant summer grid strain from extreme heat and monsoon-storm outages across the APS, SRP, and TEP service territories. Northern Arizona (Flagstaff) has a very different profile -- winter storm and wildfire-driven outage risk at elevation, closer to a mountain-West climate than the desert valleys to the south.
