New report shows Arizona added a record amount of solar capacity in 2025

New data shows that Arizona installed a record amount of solar capacity last year.

Arizona added nearly 2-gigwatts of solar power, bringing the total amount statewide to about 11.5 gigawatts. To put that in perspective, APS’ peak demand last year was more than 8 and a half gigawatts.

The gains were the largest among utilities, followed by residential and commercial sectors.

While Arizona added a record amount, the rest of the nation saw a decline in solar installation.

That drop came the same year President Donald Trump signed his major tax and spending bill that gutted clean energy tax cuts.

The report was from the research company Wood Mackenzie and the Solar Energy Industries Association.
