Development of Standardized, Low-Cost AC PV Systems: Final Technical Report, 8 September 1995 - 30 June 1998

    Research output: NRELSubcontract Report


    Solar Design Associates, Inc. (SDA), of Harvard, Massachusetts, and Solarex Corporation, of Frederick, Maryland, teamed with Advanced Energy Systems (AES) of Wilton, New Hampshire, to pursue a multi-level program under a Photovoltaic Manufacturing Technology (PVMaT) solicitation. This program was targeted at design innovation, standardization, and modularity, with the goal to deliver low-cost ACPV systems to the utility-interactive market. One significant result of this program is that Solarex filed a U.S. patent application on the new module frame and mounting system that was developed with support from PVMaT. Solarex has already started to manufacture this new combination framing and array mounting system, and a number of residential-scale installations are already in place in thefield. The major AES accomplishment under this program was the development of a reliable, FCC-compliant AC module inverter fully listed by Underwriters Laboratories (UL). The inverter passed various environmental tests, including those required by UL (the same temperature and humidity cycling tests that PV modules require), and is now in commercial production.
