Eighty-five percent of the year, the sun shines in Tucson, making the Solar Zone at UA Tech Park the perfect place for testing, evaluation, and demonstration of solar technologies and systems. The site is designed to generate 25 megawatts of power each day – nearly twice the daily electrical consumption of the Tech Park and enough to power the homes of more than 4,600 TEP residential consumers for a year.

Here, researchers and companies work together to evaluate how these technologies perform side-by-side under identical operating conditions. We have great sunshine and lots of it! Shining here with optimal solar radiance, solar technologies can be tested efficiently and thoroughly year-round.
