Arizona high school utilizes solar cooling

On the outskirts of the Phoenix metro area, one high school has harnessed the power of the intense desert sun to provide up to 100% of the facility’s cooling needs during the hottest months of the year. The solar cooling project is the largest of its kind in the U.S. and won the 2016 Intersolar Award for Outstanding Solar Projects.

A ‘perfect partnership’

In 2010, Scottsdale Unified School District in Scottsdale, Arizona, began exploring cooling options for Desert Mountain High School, which is home to 2,600 students.

“The school district was very interested in sustainability and renewable energy but needed to spend its budget on education,” said Johannes Luttenberger, chief operating officer of S.O.L.I.D. California, the stateside arm of Austria-based solar company S.O.L.I.D. “So, we developed a PPA [power purchase agreement] and invested in the solar plan ourselves.”

In order to complete the project, S.O.L.I.D. needed a design and construction partner in Scottsdale. Adroit Energy fit the bill.

“Adroit Energy is a highly innovative company with more than 30 years of experience in the renewable energy sector; they are able to deal with complex technical solutions,” Luttenberger said. “Both S.O.L.I.D. and Adroit Energy believe in the high potential of solar Continue reading

Neutra-Safe System Feeder

Neutra-Safe’s System Feeder is an automatic hydronic and thermal solar system feeder. Its 6-gallon tank introduces fluid while maintaining pressure in closed-loop systems. A digital pressure control offers adjustable cut-in and cut-out pressures between 1 and 50 psi. The unit can accommodate a remote alarm if the fluid level gets too low. Because it features a commercial-grade diaphragm pump with internal check valve, it eliminates need for a PRV and backflow preventer.
