With a high quality product required to withstand the severe conditions of the high desert that only DUOMAX from Trinasolar can offer, this 2MW project should serve as an example for the future in the solar development of Latin America and the world.

Spanning over 500 luscious acres in San Luis Obispo County, Treasury Winery Estates’ vineyards are located in Californias’ coastal mountain range. This project included installation of solar panels over the rooftops of the wine storage and grape crushing facilities. The winery received a new roof in the process of the solar installation. This cost was included as part of the installation. The installation spreads across three roof areas and interconnects to two PG&E Net Meters.

Bombard teamed with JMA Architecture Studios, JBA Electrical Engineers and Martin Harris Construction to engineer, procure, and construct a 3.5 Megawatt AC solar PV power plant at the City of Las Vegas Water Pollution Control Facility. The solar power system is located on 18 plus acres of land owned by the City of Las Vegas.

This 3.5 Megawatt system will use 15,162 Trina 230 watt PV modules and zero degree single-axis trackers, along with SMA Sunny Central 500HE inverters. Other site improvements included fencing and access gates, a new trail along the wash separating theproject site from the WPCF, a perimeter road system, site grading, and provisions for communication with the existing plant supervisory control and data acquisition (SCADA) system.

This project also includes an equipment building which provides the formal entrance to the facility and serves as a highly visible demonstration of the City’s commitment to renewable energy.

The many challenges presented by this project were overcome with Trinasmart technology powered by Tigo Energy, which improves the project economics and expected generation. By clamping voltage and increasing string length from the traditional 14 modules to 18 modules, the project used 27 fewer strings, 3 fewer combiner boxes, and 13,500 feet less wire.

The project began in 2009 because of energy consumption that year. The rates were so high that the building complex tried to become more efficient. They changed the lighting and HVAC systems, and are now one of the more energy efficiency business parks in the state. Initially, they believed that a solar system would be too expensive. But upon analysis, the principals realized that the energy cost-savings, along with federal and state incentives, made the system installation a great investment. Since then, the business park has spun off a PPA company that is involved in an additional 5MW of projects.
