Solectria Renewables’ solar inverters will be used in the 30-MW Alamosa Solar Generating Project, the largest high concentrating photovoltaic power (CPV) generating facility in the world. The solar project consists of over 500 large CPV pedestals, solar inverters and dual axis trackers. The site is located in Alamosa, CO, and extends 225 acres. The San Luis Valley in Colorado has a high altitude and is one of the best places for solar projects in the United States.
Cogentrix Energy, LLC, a nationally active independent power provider based in Charlotte, NC, said it choose the solar inverters because of their product performance at high altitudes and track record for reliable operation in harsh desert conditions.
The site is interconnected at the 115-kV transmission level and uses a photovoltaic system controller, allowing the operator to choose between a variety of smart grid operating modes. The photovoltaic system can provide large amounts of reactive power, closed loop power factor control, as well as AC voltage regulation. Moreover, the controller can throttle the site’s solar energy output to help regulate the grid frequency, when needed.
