Renewable energy strategies for the future

TEP and UES are working together in partnership with The University of Arizona (UA) on advancing solar and renewable technology.

The focus of the UA research group includes building advanced system components that allow for more solar energy collection and distribution.

This partnership remains critical not only for technological improvements but also for the research data used in creating economic policies that benefit communities.

Over 600 PV modules from 20 different manufacturers are grid-tied at the Irvington solar test site #1. We are field-testing 90 kW peak of PV systems here. Since 2003, AC power measurements have been recorded every 5 minutes from individual PV systems. Since 2009, UA researchers have monitored AC power, DC power, irradiance and temperature every second, and continue to provide real-time performance data.

SOLON Corp. has developed a PV test site to demonstrate and perform R&D for SOLON's various PV technologies starting in 2009. This site is one of three in the world using the exact same technologies that are being tested for geographic and climate diversity. SOLON has three types of PV systems in place including two fixed axis systems, a single axis tracker, and a dual axis tracker. The total capacity installed for testing is approximately 30kW.

This site is in the early stages of development, and will focus on small scale advanced PV technologies, including Concentrating PV and newer planned tracking systems. This site will also be used for testing larger modules on the order of 1kW in capacity.

Petra Solar Fixed PV System Petra Micro 200W 1

There is currently over 200 kW of fixed PV installed at the Demoss Petrie station. This installation occurred in 2001, and uses ASE 300 watt modules. This station is a smaller model of our Springerville Generating Station, where the same ASE modules are being tested to provide comparison data at different locations.
