Power Electronics in Photovoltaic Systems Workshop

Power electronics in PV systems
Tuesday, February 8, 2011 to Wednesday, February 9, 2011
ARPA-E and EERE’s Solar Energy Technologies Program (SETP) held a two-day workshop to address the role of power electronics in PV systems on February 8 - 9, 2011 in Arlington, VA.
ARPA-E led the first day’s events – “Solar ADEPT” (a continuation of ARPA-E’s Agile Delivery of Electrical Power Technology program) - and SETP hosted the second day’s events – “Solar Energy Grid Integration Systems-Advanced Concepts (SEGIS-AC).”  While the Solar ADEPT workshop addressed the challenges and opportunities associated with incorporating advanced power electronics into photovoltaic sources of electricity generation, SEGIS-AC focused on system-related issues such as grid-integration. The workshop aimed to bring together some of the world’s foremost experts in PV technology as well as leaders from industry, academia, and government with diverse perspectives to discuss the challenges and opportunities related to the generation of solar power. 
ARPA-E sought to examine innovations in modules and power electronics, and system integration.  The primary objectives of the Solar ADEPT workshop were to:
1. Identify the most challenging technological barriers to low-cost, high-performance power conversion for photovoltaics and promising R&D paths to meet such challenges;
2. Develop a realistic set of quantifiable metrics for evaluating progress towards these goals and assessing R&D success; and
3. Identify power electronics innovations that create modular converters or centralized inverters at a significantly reduced cost (~10 ¢/W) using novel materials and circuit architectures.
